If you mean the thing was not used for its intendent purpose, yes. But, who uses cell phone to make calls nowadays ? ;-)

I loved my MK 85 a lot! When I was at school in late 80s I used to store complex physics and trigonometrics formulas in it as a BASIC program text. Those days using calculators was allowed on exams so this little electronic cheat-sheet save

It's not only about kids. I usually watch videos regarding CNC stuff on youtube as I'm involved in CNC machining and I often find myself impulsively buying nifty things featured in those videos, although I understand they won&#x27

Even more, they are getting pretty close to x-ray now which begins at 10nm. The laser structure was grown on the (0001) face of a single-crystal aluminum nitride substrate. The measured lasing wavelength was 271.8 nm with a pulsed duration

My guess is this: Capacitors on DRAMs are usually implemented as PN junctions, maybe even parasitic capacitance of a transistor is used. Photons hitting depletion region of PN junction decreasing it hence increasing conductivity.

From what I understand scan rate depends on exposure time which is quite a bit high for such a sensor.

Decapping and testing this wont be difficult, meaning you understand how individual transistors are located on the die to reorder raw data into planar image. I wonder if this information can be recovered using some known patterns shown to s

Using decapped DRAM chip as photo sensor looks more promising: https://hackaday.com/2014/04/05/taking-pictures-with-a-dram-...

This is as old as a stone. I recall translating part of the essay to Russian when I used to study philosophy as a PhD student back in 2004. https://www.fabmicro.ru/~rz/Progstone_rus.doc

I admire people who designed and assembled this machine. So much of fine scrupulous work multiplied by enless hours of debugging.

Most likely a fabrication defect. Someone drilled a hole in a frame at wrong place during assembly, but to avoid reassebling the whole ship they just decided to quick-fix it using a glue-like substance. Obviously the fix did not stand for l

I wonder why this guy was trying to look at ROM inputs as binary bus trying to figure a truth table. AFAIK, they are selection lines from decoder, hence only one of the lines can be active at a time, i.e. depicted ROM is only 5 words of 10

Max sampling rate (4MSPS) is too small. Note that for more or less proper measurement you need at least Sampling_rate=Freq*4. So, for something real you need 200MSPS or even more. Beside that the idea is very cool, would buy one. Eagerly wa

That's right. But where are all those startups inventing alternatives to smartphones/iPhones/iPads ? I need a gulp of fresh air in communication.

What is so good about it that is missing in Beagle Board or in its many clones ? Just curious.

QNX ? What for ? I think RIM should learn from Nokia's mistake and switch to Android soon as possible. This is the only way to survive for them.

Seems like those guys knew nothing about HPCs. Why didn't they run LINPACK test? It's essential to measure any parallel computing system even of two cores. Also, any first grade CS student knows that the most significant part of an HPC is n

This is only one side of the virus. There's another one: the need to create things. I feel a great need to implement my _own_ ideas both in software and in hardware, i.e. first to understand the problem domain, then to create something that

Hardware. Seriously. I have been programming since I was 11 (I'm 34 atm). Couple of years ago I came to conclusion that designing your own hardware + software drives much more fun and it's not as difficult as it seems.

Ah.. MASM, AFD, Peter Norton's PC Programmer's Bible... anybody remembers how that first hyper-link based helpfile was called with all the INTs and stuff ? Although I studied programming (I was 13) one of those Soviet IBM System/360 clones

Are you joking ? How do you distinguish this "leaked oscillation" coming from radar-detector from all other pieces of electronics your car is stuffed up with ? Say, from your car stereo ?

I'm located outside of US, though would be happy to try your piece of hardware in my environment. Email sent.

I think by "emmitting" Tocomment means "sending update to the server", thus notifying everyone who is connected and is in some certain range from the point.

Ari, aside from legal issues, I think it mostly depends on how hard the installation process is going to be. If you manage to design a very small PCB which will use bluetooth, can be fit inside radar and needs only three wires to solder (D

I'm pretty much fascinated with the idea. Every radar-detector has one or several LED indicators. What you need is just to hook up to these LEDs and you will support virtually any radar-detector available on the market. The cost of componet

Did you pay your taxes already ? I wonder what would be your after-tax income ? Again, $2.5k is still very low even for Eastern Europe. From my own experience, I strongly recommend NOT to quit your day job. Try to run it at least for a year

They use VLF/ELF to send "message pending" and/or some other very short predefined signals. Russian military transmitter (ZEVS) is still operating on 82Hz frequency and uses Earth as an antenna. http://en.wikipedia.org/wiki/Extremely_low_f

There are many extraordinary things have been done in robotics in recent, and a lot many to be done yet. Just try to "teach" a self-balancing biped to run. In theory it's possible to run over walls and ceiling in your room (if you run fast
