With a surplus of 3D printers at this year’s Maker Faire, it’s really surprising to see the most talked about tool among the makers is a simple oscilloscope.
[Gabriel Anzziani]’s Xprotolab is an extremely small oscilloscope, function generator, logic analyzer, and general 128×64 OLED display is the perfect addition to your next prototyping project. With its breadboard friendly format and USB output, it will dutifully serve as a 200kbps oscilloscope, 8 channel logic analyzer, or as seen in the video above, the perfect interface for a Wii Nunchuck or just a simple digital Etch-a-sketch.
In the video above the fold [Gabriel] shows off the functions of his tiny, if somewhat limited, OLED oscilloscope.
Good thing. If this was half price I would even permanently include it in some projects.
Definitely seen this posted here before.
seen this post too before…
…..erm…. “200kbps oscilloscope” ?????
Not an issue, just use a frequency
divider based on a superhet.
This is how they used to do >2G
on an old style ‘scope, back in
the old Tektronix days :-)
That and using tunnel diodes helped.
Nice. I would like to find out where I can buy these screens. I think I will pair one up to a stellaris when it comes and make my own ‘scope.
BTW – when you are interviewing in a noisy environment, it would be really useful if you can give the presenter a mic (clip-on, handheld, whatever). The background noise makes it really difficult to catch what’s being said.
they are easy to find on ebay. you can even get some on PCBs, just search for ‘oled display’.
@bothersaidpooh it’s not the number that is low, it is the unit after the number that is wrong.
Adafruit has some nice ones in different sizes on a breakout.
At the Stellaris launchpad forums, bluehash has already begun work on a similar oled.

It’s a carry over from the MSP430 OLED boosterpack

I saw these at the mini make faire in Orlando. I should have picked one up, but for some reason i didn’t. Maybe next year…
Pretty neat little gadget.
Wow, They are double the price from my local distributor (Mantech Electronics). I Would buy one other wise!
Are you talking about Mantech Electronics in Cape Town? I also shop there.
I just found out about these recently. They’re cool. He’s using an ATXMega in them…very nice work.
I’ve been developing an even smaller development platform using a 128×32 OLED display…I’ve got a little more work to do, but I’m hoping to have some ready for the world soon. [The video is pretty bad…just put it together for a friend of mine].
“a 200kbps oscilloscope”
Really? Can you at least pretend to have read the article and/or understand oscilloscope specs?
The scope and logic analyzer are 2MSPS and the scope is 200kHz analog bandwidth. The function generator is 1MSPS and 44.1kHz bandwidth.
Completely useless!
Agree
Might be useful for audio stuff, fixing amplifiers, and any other stuff that, well, works at less than 200Khz.
Completely useless… for you only. I for one have plenty of uses for them. Just as I have plenty of uses for my 300kHz function generator.
At last! Now I can get rid of my Tek 500 series scopes – all six of them.
This was by far the worst camera man on earth.
Thanks hack a day for the article!
For people interested, I have started a Kickstarter project to design a portable version of the Xprotolab.
