Post by thread:[PICLIST] [EE] GameBoy Sampling Oscilloscope

Howdy, I found an old article about the Nintendo GameBoy Sampling Oscilloscope-project. It seems very priceworthy and interesting since I have a gameboy, I am a student with low budget and I need an oscilloscope. 1. Has anyone tried it? Experiences? Costs? 2. Anyone know it it works with the original GameBoy, or just the newer pocket size/color models? I don't see why they should not be 100% compatible, but who knows..? All the necessary information and further links can be found in this "Elektor Electronics" article in PDF, Issue 10, 2000. http://www.ziegler.desaign.de/gbdso_uk.pdf Thanks in advance, Magnus von Rosen, Sweden. Some data: Dual trace display Sampling Rate: DC to 1Msps Time Base: 100Sec to 5uS/Div Inputs: AC/DC 1Meg Ohm Input gain: 50mV to 10V/Div with 10:1 probes Line or chart recorder trace modes Real time FFT mode with dB scale Variable persistence XY mode PC link for screen or data transfer 5hrs operation from NiMH batteries Averaging and Auto trigger functions Reference trace storage -- http://www.piclist.com#nomail Going offline?

Wow, this looks like one of the coolest project I ever seen.

Hi på Dere, I have the GameBoy Oscilloscope. It is quite good really only usable for AF purposes. I believe it will work on a black & white GameBoy because it doesn't use colour for its display. If you are considering building it, you may have difficulties obtaining one of the Maxim chips. Maxim are still quoting a 15 week lead time and they've been quoting that since 2000. Future-Active do have it, but they don't seem to respond to non account holders (at least outside the States). I think Elektor have now run out of ready made models. If you're still interested email off list. Ha Det Godt Colin -- cdb, bodgy1spam_OUToptusnet.com.au on 05/06/2002 -- http://www.piclist.com#nomail Going offline?

Obviously a lot of time and effort went into the software, and it generaly works very well. In fact the only two problems I have seen so far are 1) The buttons are very unresponsive when you have long timebase settings, and 2) the screen flickers at certain timebase settings. This is on a Gameboy "Pocket" (black and white) but it works on the older gameboy (although it a fiar bit bigger and the display isn't as good). We did find some problems trying to source some of the op-amps, and eventualy we substituted them, can't remember details now but I'll check it out if you want the info. I've used it quite a bit for automotive use, looking at injector waveforms etc. Regards Mike -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

Thanks for the info! I think I will abandon the project for now anyway, the components seem hard to find, and the prospect of soldering surface mounted IC's isn't that tempting, at least not with my amateur "lab" (Ha! Lab? Ha!) Besides, it seems I can get a used Oscilloscope for a lower price than building the gameboy thing. But perhaps in the future, when I become filthy rich? :) Greetings Magnus {Original Message removed}
