AVR Shark Tag Project

microcontroller project animal tag
The goal of this project was to develop a shark tag working bench-top microcontroller platform. It is to be used for on-animal, in-situ data logging applications involving sharks and potentially other large pelagic.

The project used the Atmel Mega32 microcontroller to develop the core platform and functionality of a data archival tag. The project use temperature and pressure as sensor variable. The tasks ranged from logging sensor data to developing a simple user interface that requires only the addition of a laptop and a custom RS232 serial cable in the field.

It used an off-the-shelf SD (Secure Digital) card using flash memory for large capacity multi-read/write data storage. The microcontroller’s ADCs (analog to digital converters) were used to convert analog voltages produced by select sensors into digital format.

USB AVR ISP downloader

usbasp_kit Dari judul nya pasti semua dah pada ngiler pengen nyoba nih project.. he3…,

YUpz,,, kita akan coba bikin USB downloader buat Atmel AVR microcontroller..

Firmware, Schematic n Driver project nih ak dapet dari temenku Achmad Fiqhi (meet him on FaceBook: vik_ah@yahoo.co.id).

Dia dah nyoba alat ini, n lancar2 aja. Budget yang dia kluarin skitar 50 ribu, jauh lebih murah ketimbang beli USB Downloader yang harganya rata2 diatas 150rb. Makasih banget pokoknya buat temen yg satu ini dah mau bagi2 ilmunya.

Project ini berbasis ATmega48 tapi bisa juga pake’ ATmega8. Yang perlu diinget Firmware nya harus tepat. Di akhir atikel ini kita sudah sertain file2 yang berhubungan dengan project ini,

  • Rangkaian Schematic
  • Firmware
  • Driver
  • AVRdude

Rangkaian Schematic

    buka folder “circuit
    buka file USBasp.sch menggunakan software PCB maker seperti EAGLE
    dalam file sch ini terdapat contoh rangkaian yang menggunakan ATmega48.
    temen2 bisa mengganti ATmega48 ini dengan ATmega8

Firmware

buka folder “../bin/firmware

disini terdapat file usbasp.atmega48.xxxx-xx-xx.hex (gunakan file ini jika menggunakan ATmega48)

dan

usbasp.atmega8.xxxx-xx-xx.hex (gunakan file ini jika menggunakan ATmega8)

untuk memasukkan firmware awal maka kita harus menggunakan downloder laen yang dah jadi seperti DT-HiQ AVR ISP nya innovativeelectronics.com ato downloader USB nya klinik-robot.com .dll…

ingat… set jumper J2 saat mengisikan firmware

Driver

begitu Firmware dah dimasukin ke micro, berarti USBdownloader kita dah siap pake… tinggal colokin ke PC..

saa dicolokin maka windows akad detect nih sebagai “new hardware” n butuh driver.

Nah drivernya ada di "bin/win-driver".

trus windows pasti bilang klo nih hardware “not digitally signed… n bla bla bla…….” pilih continue anyway.

AVRdude

Yooww sekarang kita bisa memasukkan program ke Atmel AVR microcontroller menggunakan USBdownloader kita.

Untuk memasukkan nya kita memakai software AVRdude.

caranya:

klik build.bat ato mega8.bat

pokoknya file “.bat” di dalam folder “.. bin/firmware“ (folder tempat “avrdude.exe”)

lalu akan muncul commandprompt (jendela layar hitam)

ketik:

avrdude -c usbasp -p atmega8535 -U flash:w:main.hex

untuk memasukkan program main.hex ke mikro ATmega8535

NB:

  • FIRMWARE adalah program yg ada pada microcontroller sebuah sistem. Suatu sistem berbasis microcontroller tentu gak akan jalan jika micro nya gk di program.. nah program di dalam mikro ini namannya firmware

Jumper2 pada USBdownloader ini adalah:

  • J1 (supply power target). Target bisa menggunakan supply +5V dari PC dengan men-set jumper ini. HATI-HATI saat menggunakan jumper ini karena jika target board short circuit resiko nya PC/laptop kita.
  • J2 (update firmware). Set saat mengisi awal atau mengganti program /firmware yg ada pada micro di USBdownloader ini. Penggantian firmware dengan bantuan Downloader yg laen
  • J3 (SCK option). Jika clock target di bawah 1,5MHZ maka jumper ini harus di set. sehingga SCK akan diturunkan dari 375KHz menjadi 8KHz

Download Firmware , Schematic dan Driver project ini di:

Why the Wii needs a price cut fast



Smooth ride up until now

The Wii needs a price cut fast and here is why. Up until now, Nintendo has had a very smooth ride this generation. They started out with the lowest price proposition by far and the most revolutionary, intuitive and immersive control scheme and biggest fun factor to top it all off. At least, that is what more than 50 million people around the globe think.

Sure, the white box can only deliver 480p as its top resolution. And the rest of its hardware is equally modest, making sure that most graphics-intensive games by third parties get either a toned down version, a completely unique adaptation (some examples are ´Overlord: Dark Legend´, ´Dead Space Extraction´, ´Resident Evil: Darkside Chronicles´) or pass the console by completely. But, all the unquestionable Nintendo goodness aside (´Metroid Prime 3´, ´Zelda: Twilight Princess´, ´Super Mario Galaxy´), hardcore gamers got a few third party gems, too. Particularly in the survival horror genre, Wii boasts more titles than any other console ever offered, I reckon (I have counted 20 already) and some are absolute must-haves. So, Wii sold to new gamers as well as to veterans, who probably own more than one console anyway. And it has been smooth sailing for Nintendo up until now, with Wii selling about as many units as the two competitors put together.

Microsoft seemed to endlessly tweak the SKU variety of their Xbox360 as well as their price. And, leaving the elusive fun factor aside, the 360 has been the best value proposition by far for a long time. But even this circumstance could not change the reality that is each companies' respective market share. Sure, Nintendo has hit dry spells in the past, with other consoles selling more units for a few months in one territory or another. But these dips were usually related to a lighter release calendar. When bigger titles drew nearer, sales rose again.

Software no longer moves hardware

Not anymore, it seems. The news of Wii hardware sales taking a 30 percent dip in the US last month despite the release of ´Wii Sports Resort´ should have Nintendo worried. Very worried, in my opinion. Because the title should move hardware as much as any other Nintendo game. A gigantic marketing campaign in the US should have made sure that the consumers were aware of the release. The fact that it did not move a significant amount of hardware can only really mean one thing: everyone that wanted to buy a Wii in the said territory has bought one. If a title like ´Wii Sports Resort´ cannot invigorate sales, then no title can (at least not of Nintendo's casual variety, which undoubtedly was the backbone of the console's success). The only option available to Nintendo of America may be a price drop. This would surely convince more people to hop on the Wii bandwagon. But software no longer seems to move hardware.

Upcoming games to disappoint

First, a little reality check: Am I being unfair here? Of course, all the other consoles sold badly in July. Well, yes. But the PS3 only took a 25 percent dip and the 360 went down a mere 15 points, only half of the Wii's loss. That is a significant difference. But what about other territories? In Japan, year-to-date year-over-year changes show big losses for the console. Europe may be the Wii's last resort (this is actually a double pun, if you remember an obscure PC game from 1996) but a worldwide downward trend is becoming clearer and clearer, it seems.

But what about other upcoming titles, particularly the third party portfolio, which is still a sore spot for Wii owners? Surely, exclusive titles like ´Monster Hunter Tri´ or ´Red Steel 2´ will sell hardware to the traditional crowd, if the more casual titles now fail to shift consoles. Unfortunately, I have it on good authority that both of these highly anticipated games will not deliver. They may look nice, but both titles are being rushed out of the door. Wii owners will have a few good survival horror titles to mull over. But there is no shortage of those on the platforms. So a ´Dead Space Extraction´, no matter how good it will be, will not become the killer app that a polished ´Monster Hunter Tri´ could have become.

Price cut the only solution

Especially with the PlayStation3's price drop and sleeker re-design, as well as motion control around the corner for both high definition consoles, Nintendo is coming under intense pressure this generation for the very first time. The only way out seems to be a price cut, preferably to be announced around Tokyo Game Show next month (though Nintendo will not exhibit, as always). I do not see any alternative for Nintendo (and I am not alone with this opinion), if they want to maintain the impressive momentum they have exhibited so far. This is the curse of a runaway success: maintaining it. After all, a boom, in economics, is a highly unstable and volatile state. And if they do not re-position the Wii's price point, Nintendo may soon find out the hard way.

EDIT Looks like I was spot on with my analysis. The following image was published by Kotaku. It may be fake, of course. But both the timing and extent of the price cut would fit perfectly, so I believe it is legit.

Land of the Lost

I am going to break with my typical "bad blogging" habits... my penchant for writing long, carefully edited and punctiliously argued screeds dealing with serious topics (everyone says that is NOT the way to blog!)...

...and instead issue a short, ill-edited rant on popular culture.
(Ah! Now Brin is catching on top what the Internet is FOR!)

The topic? That infuriating television show LOST.

I'm going to list the inconsistencies and frustrations that most vex me in this series. They are probably not the same as what you'll read at, say, one of the fan sites, because I view it through the lens of a professional plot-smith.

First, I do try to view art in the spirit that it is offered -- and I know that the writers and producers of LOST are engaged in the art form known as the Grand Tease. Hence I won't complain about the fundamental premise -- that no character ever asks any crucial questions, not even when they had the leisure of 3 years to ask them. No, that is a central theme of the series and anyone who can't abide it simply should not watch.

But some things were revealed and made explicit. earlier. They should have been kept in mind as the series developed. They were huge clues. They deserved payoff. And, although some may seem minor, ignoring them should be cause for the producers to be (figuratively) shot!

1) The children and stewardesses etc of the crashed Oceanic flight. They were taken away by the Others. Dozens of them We even glimpsed them, near the Polar Bear cages, in one episode. A major plot element, they are now (in show-year 2006) the main group of survivors left. Above all they are the only true INNOCENTS left, and hence the ones who deserve any loyalty or attention or moral duty in the story.

2) Plot elements left hanging: The "disease"... the mysterious lethality of childbirth... the SOURCE of the "others" -- who apparently were recruited by "a magnificent man..." the deGroots and Hanso and their goals...

3) The air drop of Dharma supplies. Yes, when the Oceanic survivors found parachuted supplies meant for the last Dharma outpost in the Hatch... sure it only happened once , but the implications were HUGE! It meant that there was still a Dharma initiative out there! It implied another route to the island than by submarine. Did it bother ANYBODY else out there? It ought to.

4) Heck, what happened to the Dharma and the guys backing them and the group in Ann Arbor? Did they learn ANYTHING after all that expense and effort?

An side -- what IS it with the obsession in all TV series, of leaving contemporary society unchanged? STARGATE was a great show, but their excuses for NOT FREAKING TELLING THE WORLD that Earth was fast becoming an intergalactic imperial power started getting really, really lame. Would it have hurt to show what WE might have done, reacting to such news?*

5) There is only one character in the tale who is not relentlessly clueless and stupid. The one character who is always, always right. Hurley. The writers always show him suggesting openness and wisdom, and getting contemptuously, patronizingly spurned by his friends. He's the only one who wanted simply to tell the world about the island! And thus... render all sides in the silly "war" moot and let all humanity learn all about something miraculous that we could all share.

Is Hurley EVER going to be listened-to?

6) What the $%#! have all the governments of the world been doing, all this time? Not ONE person, anywhere or anytime, ever told any responsible group of adults about all the shenanigens going on, with incredible powers? Sure, it's more dramatic to leave the government out of it. That is... unless a pair of FBI agents - looking suspiciously like Mulder and Sculley - were to arrive and speak out for telling the world....

6) Death guilt. There were hints, throughout the first two seasons, that you were either chosen by the Others - or not - depending on whether you had killed somebody or done something else that caused you to feel guilty. Jack and Hurley felt INDIRECTLY guilty, and so we left on the beach. Locke at the time had no guilt and I thought that was his reason for being "chosen". He even avoided "re-killing" his own father...

...that is, till he outright committed unprovoked MURDER by hurling a knife into the back of an innocent woman. Wha???? HAve the writers forgotten all about that thread? When Ethan told the murderer female cop "you're not worthy" they made this point very clear! Only, then they show the Others committing murder like crazy! So, WTF?

7) Speaking of Locke's father... wasn't he taken out of a "magic box" by Benjamin Linus? What ever happened to that?

Okay okay... I should have just turned off the damned box, a couple of years ago. The last season is already filmed (though a few minutes of spliced in conversation is still possible). Maybe we are best served simply by boycotting the final season, to teach a lesson to Abrams and others like him, who do not care about fealty to plot.

====

* I'll go see DISTRICT 9 soon. I hear good things. Still, I think the same concept, done in the 1980s, was intrinsically more courageous. Rent ALIEN NATION and see how that brave film did something no other ever even tried -- either before or since. It portrayed our civilization -- and its citizens -- actually behaving as they might, if such things ever happened for real.

In other words... a majority of us actually trying to behave decently and well, with tolerance and courage and smarts and a will to face the future.

Hollywood, it seems, not only cannot ever portray such things... people there cannot even seem to wrap their minds around the idea! Hence, alas, we come full circle to poor Hurley.

He represents the rest of us. The ones with more brains and heart than movie star looks. The poor schlumps with common sense.

The Real Way to Feel Safe with Artificial Intelligence

Sorry to have posted so little, of late.  We have been ensnared by a huge and complex Eagle Scout Project here... plus another kid making Black Belt, and yet another at Screenwriting camp... then the first one showing me endless online photos of "cars it would be cool to buy..."

And so, clearing my deck of topics to rant about, I'd like to post quickly this rumination on giving rights to artificial intelligences.  Bruce Sterling has lately raised this perennial issue, as did Mike Treder in an excellent piece suggesting that our initial attitudes toward such creatures may color the entire outcome of a purported "technological singularity."


The Real Reason to Ensure AI Rights

No issue is of greater importance than ensuring that our new, quasi-intelligent creations are raised properly.  While oversimplifying terribly, Hollywood visions of future machine intelligence range from TERMINATOR-like madness to admirable traits portrayed in movies like AI or in the BICENTENNIAL MAN.  

I've spoken elsewhere of one great irony -- that there is nothing new about this endeavor.  That every human generation embarks upon a similar exercise -- creating new entities that start out less intelligent and virtually helpless, but gradually transform into beings that are stronger, more capable, and sometimes more brilliant than their parents can imagine.

The difference between this older style of parenthood and the New Creation is not only that we are attempting to do all of the design de novo, with very little help from nature or evolution, but also that the pace is speeding up. It may even accelerate, once semi-intelligent computers assist in fashioning new and better successors.  

Humanity is used to the older method, in which each next generation reliably includes many who rise up, better than their ancestors... while many others sink lower, even into depravity.  It all sort of balanced out (amid great pain), but henceforth we cannot afford such haphazard ratios,  from either our traditional-organic heirs or their cybernetic creche-mates.

I agree that our near-future politics and social norms will powerfully affect what kind of "singularity" transformation we'll get -- ranging from the dismal fears of Bill Joy and Ted Kaczynski to the fizzing fantasies of Ray Kurzweil.  But first, let me say it's not the surface politics of our useless, almost-meaningless so-called Left-vs-Right axis. Nor will it be primarily a matter of allocation of taxed resources. Except for investments in science and education and infrastructure, those are not where the main action will be.  They will not determine the difference between "good" and "bad" transcendence.  Between THE MATRIX  and, say, FOUNDATION'S TRIUMPH.

No, what I figure will be the determining issue is this.  Shall we maintain momentum and fealty to the underlying concepts of the Western Enlightenment? Concepts that run even deeper than democracy or the principle of equal rights, because they form the underlying, pragmatic basis for our entire renaissance.


Going With What Has Already Worked

These are, I believe, the pillars of our civilization -- the reasons that we have accomplished so much more than any other, and why we may even succeed in doing it right, when we create Neo-Humanity.

1.  We acknowledge that individual human beings  -- and also, presumably, the expected caste of neo-humans -- are inherently flawed in their subjectively biased views of the world.  

In other words...  we are all delusional! Even the very best of us.  Even (despite all their protestations to the contrary) all leaders.  And even (especially) those of you out there who believe that you have it all sussed.

This is crucial. Six thousand years of history show this to be the one towering fact of human nature.  Our combination of delusion and denial is the core predicament that stymied our creative, problem-solving abilities, delaying the great flowering that we're now part-of.  

These dismal traits still erupt everywhere, in all of us.  Moreover, it is especially important to assume that delusion and denial will arise, inevitably, in the new intelligent entities that we're about to create.  If we are wise parents, we will teach them to say what all good scientists are schooled to say, repeatedly: "I might be mistaken."  But that, alone, is not enough.

2.  There is a solution to this curse, but it is not at all the one what was recommended by Plato, or any of the other great sages of the past.  

Oh, they knew all about about the delusion problem, of course.  See Plato's "allegory of the cave," or the sayings of Buddha, or any of a myriad other sage critiques of fallible human subjectivity.  These savants were correct to point at the core problem... only then, each of them claimed that it could be solved by following their exact prescription for Right Thinking. And followers bought in, reciting or following the incantations and flattering themselves that they had a path that freed them of error.

Painfully, at great cost, we have learned that there is no such prescription. Alack, the net sum of "wisdom" that those prophets all offered only wound up fostering even more delusion.  It turns out that nothing -- no method or palliative applied by a single human mind, upon itself -- will ever accomplish the objective.  

Oh, sure, logic and reason and sound habits of scientifically-informed self-doubt can help a lot.  They may cut the error rate in half, or even by a factor of a hundred!  Nevertheless, you and I are still delusional twits.  We always will be!  It is inherent.  Live with it.  Our ancestors had to live with the consequences of this inherent human curse.

Ah, but things turned out not to be hopeless, after all!  For, eventually, the Enlightenment offered a completely different way to deal with this perennial dilemma.  We (and presumably our neo-human creations) can be forced to notice, acknowledge, and sometimes even correct our favorite delusions, through one trick that lies at the heart of every Enlightenment innovation -- the processes called Reciprocal Accountability (RA).  

In order to overcome denial and delusion, the Enlightenment tried something unprecedented -- doing without the gurus and sages and kings and priests.  Instead, it nurtured competitive systems in markets, democracy, science and courts, through which back and forth criticism is encouraged to flow, detecting many errors and allowing many innovations to improve.  Oh, competition isn't everything! Cooperation and generosity and ideals are clearly important parts of the process, too. But ingrained reciprocality of criticism -- inescapable by any leader -- is the core innovation.

3.  These systems -- including "checks and balances" exemplified in the U.S. Constitution -- help to prevent the kind of sole-sourcing of power, not only by old-fashioned human tyrants, but also the kind of oppression that we all fear might happen, if the Singularity were to run away, controlled by just one or a few mega-machine-minds. The nightmare scenarios portrayed in The Matrix, Terminator, or the Asimov universe.


The Way to Ensure AI is Both Sane and Wise

How can we ever feel safe, in a near future dominated by powerful artificial intelligences that far outstrip our own? What force or power could possibly keep such a being, or beings, accountable?  

Um, by now, isn't it obvious?

The most reassuring thing that could happen would be for us mere legacy/organic humans to peer upward and see a great diversity of mega minds, contending with each other, politely, and under civil rules, but vigorously nonetheless, holding each other to account and ensuring everything is above-board.  

This outcome -- almost never portrayed in fiction --  would strike us as inherently more likely to be safe and successful.  After all, isn't it today's situation?  The vast majority of citizens do not understand arcane matters of science or policy or finance.  They watch the wrangling among alphas and are reassured to see them applying accountability upon each other.... a reassurance that was betrayed by recent attempts to draw clouds of secrecy across all of our deliberative processes.  

Sure, it is profoundly imperfect, and fickle citizens can be swayed by mogul-controlled media to apply their votes in unwise directions.  We sigh and shake our heads... as future AI Leaders will moan in near-despair over organic-human sovereignty.  But, if they are truly wise, they'll continue this compact.  Because the most far-seeing among them will recognize that "I might be wrong" is still the greatest thing than any mind can say.  And that we reciprocal criticism is even better.

Alas, even those who want to keep our values strong, heading into the Singularity Age, seldom parse it down to this fundamental level.  They talk - for example - about giving AI "rights" in purely moral terms...  or perhaps to placate them and prevent them from rebelling and squashing us.

But the real reason to do this is far more pragmatic.  If the new AIs feel vested in a civilization that considers them "human" then they may engage in our give and take process of shining light upon delusion. Each others delusions, above all.

 Reciprocal accountability -- extrapolated to a higher level -- may thus maintain the core innovation of our civilization.  It's central and vital insight.

And thus, we may find that our new leaders -- our godlike grandchildren -- will still care about us... and keep trying to explain.

Pressure Sensitive Keyboard

Some of my colleagues in the Applied Sciences group in Microsoft Hardware have recently gotten some media exposure for one of their recent projects: the pressure sensitive keyboard



Congrats! It's a very nice prototype, and I look forward to seeing what the students at UIST cook up in the innovation contest.

If you aren't familiar with UIST (User Interface Software and Technology), it is a conference dedicated to new interface research. It is one of my favorite conferences to attend. It's where I demonstrated my past work like Automatic Projector Calibration, Foldable Interactive Displays, where Chris Harrison (recently known for Physically Changing Displays) showed off Scratch Input, Andy Wilson showed early pre-Surface touch tables, Hrvoje Benko showed Spherical Surface, MSR-Cambridge presented Second Light, and where Jeff Han first demonstrated FTIR. ...and that's just a small sample from the last 2-3 years.

So if you are interested in new interface technology (or you are part of the tech media) I would encourage you to attend UIST in October this year. You'll get to see what the latest interface researchers are doing all over the world and get to talk to the people behind the ones you have read about.

New Site in the works

I will be moving everything over to my new site very shortly, and I will include a better tutorial on how to mod you controller with the d-pad as well.  Thanks to the many who have emailed asking for it.  I want to get my first game project out on the Indie Games channel, and then I will move everything over.  So hopefully within the next two weeks.

Flash Cards

Getting back to a project that I started with almost a year ago, a project that was my first attempt with any form of programming outside of Basic in Junior High that is. This is based off something I made using many years ago with a presentation program, I had it simply loop through cards every few seconds with the alphabet, numbers, colors, shapes, different objects and animals.

I decided to use this as my first program idea for Xna, it is something my son now uses and used in the past. And it was neat to see him very early on in his life identify something that he had seen in the game(ok it was a slide), and try to say the word. The first time we took him to the Zoo it was a neat experience for many reasons.

As it stands this game does not yet include animals or other world objects, I cannot draw well enough, and I am still checking on the rights for using clipart.

The neat thing about what the Xna team has done, is that we can now upgrade our games at any time, and when you load your game it will notify you if there is in an update. You no longer have to go and check to see if an Indie game has been updated.

So here are the latest screenshots, I fully expect to put this game out for peer review next week.







I have added the ability to pause on a certain object, if you want to concentrate on a certain letter for instance. You can play without audio by pressing X to select that set of cards, while pressing A will play audio. There is a mini game in the credits, you can move a rocket around the screen with the left thumbstick.

After each screen is done looping it will exit back out to the main menu, currently it takes 3 seconds between cards.

There is also a trial mode, but it limits each screen to the first three objects.
