DIY Oscilloscopes – List and Discussions

Hello, all crazy lunatics of DIY electronics! Me myself – I sure qualify to that description. Recently I got seriously addicted to DIY oscilloscopes. Different kinds of them, any level of complexity really. I was, and still am, collecting links, information, solutions, technical details. Trying already many of them. Why? Because it is addiction, and, feeding your addiction releases some “happiness hormones” into your brain, that’s why. I don’t really need oscilloscope as a tool. Have some decent ones at work, and not even using them that much. So, my point is – I have great fun finding DIY scopes projects and trying them.
Now, when I look at my bookmarks and materials I have collected to this topic, two things comes to mind. First – obviously, I am insane. But that’s okay, nothing new here. But second – hmm, lotsa work done collecting all that. So, I decided to share my findings, and encouragement from some authors and discussions participants helped, so that I am really doing it.
—–End of Lyrics ———–

Here I will maintain list of DIY scopes that I have found (and YOU will suggest) and considered interesting for one reason or another.
At first, I will post just list with, minimum (or none) descriptions. When I feel like it, I will add stuff, by editing and expanding original post.
Links to resources will be coded in groups. That, I imagine, will keep things a bit organized, and will help to reference to particular projects in upcoming discussions, if there will be any. For example, “I just tried S-03-(T) and it sucks enormously”. You got the idea.

GROUP CODES:
—————-
S-xx “Simple”, projects that have some MCU and not much else, or some other very simple solution. I mean simple just hardware-wise, don’t ignore them. If some just one MCU has 4 internal ADCs working in tandem (“quandem”…? is that a word?), results might be pretty interesting.

M-xx “Medium”, usually it will be MCU(s) plus some external ADC(s), input buffers, etc, etc.

A-xx “Advanced”, those are where things got pretty serious, usually involving FPGAs and other esoteric magic.

N-xx “Not-Finished”, projects that looks very interesting, but are maybe not finished, maybe migrated to somewhere, maybe will come back, maybe we will find where is it now.

C-xx “Clones”, direct or semi-direct clones of commercial products. Copied, reverse engineered.

P-xx “Price”. Kind of DIY, but you can not really, well, DIY. Need to pay for something. I did want to name it “G” for “greed”… Still, there are some really interesting ones, and let’s hope we migrate them to “C”-category someday.
—————–

NUMBERING
list numbers “xx” does NOT represent importance, coolness, bad-ass-ness, or anything, really. Just some number for reference. Except for “S-01”. But you will see why.
—————–

SUFFIXES
(T) – tested by me. Not necessary in finished state, but somehow tested.
(RU) – source in russian language (i am latvian, but I also know russian and english).
(DE) – source in german.
(PL) – source in polish language.
(…) – maybe some other languages too.
For “T”-marked there usually will be link to some pics of my testing.

Okay, here we go:

DDS module optional.
Android APK, and also Windows GUI. Looks like latest iteration can work to Android via USB too.
Nice! I am going to build it.

Thanks to zoomx for pointing to this one. It is low bandwidth, Arduino-based, with added analog input shield.
It looks like its ultra-detailed instructable can be good source for learning.

Just found out about this DIY USB scope project (thanks for tip, Apex!!), and it looks interesting to me – not overcomplicated, but with modern FPGA. It says there, that software is free, but non-copyable, so you have to contact Author for making it for individual use. My guess – Author is providing firmware that is locked to particular hardware (new project “GFXscope v3.0” (my code P-02-(RU)) is doing similar). I will contact Author, will post here, what are terms of getting firmware.

Nice… as I believe I may have said before, you can never have too many oscilloscopes.. or multi-meters.
I suspect you may however have just provided the catalyst to increased the “clutter” in the ahull household. I’m not sure my wife will approve.

@ThunderOwl I am not offended
I mentioned my oscilloscope just for the record, because you have done great job with the ‘DIY Oscilloscope’ list.

I just found another one, and it is STM32, and really simple and interesting – I am definetely going to build it! Well, not much to actually “build” there, really. It is this one in list:

There are some clones.
I have this one and I use it sometimes.

Thank you, zoomx. Well, DSO138 has become kind of “household item”, I did not include it in list, too obvious Will go thru other your links and include them in main list in next days.

This is successor to “GFXscope v2.0”, that was on STM32F303. User GFX admits that other two users (Alex2 and Yurick) are more authors than him, but it still goes named “GFXscope” . Firmware is not free, it is about 16 Euros (1000 russian rubels). I already bought it (with future updates, of course), and started to assemble “test bed” (see pictures). Looks like developer(s) got frustrated with limitations of F103 and F303 chips, and moved higher. Good thing I already had a board with F407. Also, in new project TFT has parallel connection to STM, so, less overcrowded SPI, I guess.

I noticed HobbyKing has this STM32 based scope on their deal of the week

https://hobbyking.com/en_us/dso138-osci … n-kit.html

Though its not entirely cheap what you get as part of the kit apart from the PCB + STM32F103C8 + Display

(or whether its such a good deal)

As I said my thought before – DSO138 is kinda “household” item now (like can opener or something, or flashlight ), they are everywhere, originals and clones, cost almost nothing, but not very good either, usable to some 300kHz, so I read. There is slightly updated version DSO150, but it is not updated in main charasteristics, so it is in the same ballpark. I think it is interesting on its own, but not for DIY heavy experimentators like us

Today, I semi-finished DIY clone of simple “Xprotolab Plain”, by “Gabotronics (list code M-10).
Pictures (not very good quality for now):
http://bildites.lv/a/69nvgudn#zc9vn6ch
it is low bandwidth device. I kind of like its Windows host software.

Entry S-14 now has “(T)” suffix, it is tested by me. Almost finished construction:
http://bildites.lv/a/xfjbphbf#6cn35b7u
as any STM32F103 based scope without additional hardware, it is usable for some tens of kHz.
When (if..) Author updates design, I will follow that and post here.

with the recent fad on stm32f407** boards
http://www.stm32duino.com/viewtopic.php … 91&p=25673

i’m thinking that we could literally do a version for stm32f4 as well
someone has done a pretty decent 16 ch x 20 msps logic analyzer
https://code.google.com/archive/p/logicdiscovery/

looking at the specs
http://www.st.com/content/st_com/en/pro … 407ve.html
-3×12-bit, 2.4 MSPS A/D converters: up to 24 channels and 7.2 MSPS in triple interleaved mode
… USB 2.0 high-speed/full-speed device/host/OTG controller with dedicated DMA, on-chip full-speed PHY and ULPI
with usb 2.0 high speed raw signaling rate of 480 Mbit/s, throughput at perhaps 200 mbps
https://en.wikipedia.org/wiki/USB#USB_2.0

assuming that it is possible to achieve the theoretical 7.2 msps x 12 bits ~ 86.4 mbps
my guess is that 1 could literally wire that ADC data stream back to the pc & display that in real time
or the permutations of 3 x 2.4 msps or 6 x 1.2 msps

I did some testing of various op-amps that I had, how does meandr looks like at 500kHz and 1MHz on one and the same oscilloscope hardware.
Maybe interesting to someone:
EDIT (important!): link to images is changed, and pictures are changed too. Previous tests were at wrong input conditions, MY BAD! I appologize…
http://bildites.lv/a/27ksd5sc#cvytkerv (this is new link, correct pictures)

(i tried to attach zip file with pictures here, but 1MB is too large for this place)

Not sure if any of you have seen this before…

… they don’t make ’em like that any more.

OMG Thank G
once upon a time they were the ‘advanced’ model
