'[PICLIST] [EE] GameBoy Sampling Oscilloscope - any'

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

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

Look into eBay. 'scopes like a Tek 465 are _very_ reasonable. These are
oldies but goodies.

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

A couple of us at work built it, and it certainly "does what it says on the
tin".  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

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
