Today I used my modestly expensive oscilloscope to track down a critical bug in my code: I forgot to de-assert the RESET signal. #engineering #oscilloscope #coding #EmbeddedSoftware
Today I used a Red Pitaya and I thought maybe I should buy one. Later, I remembered I am poor.

Cool project that turns a Sony Watchman into a WiFi and Bluetooth enabled vector display! I’d love to try and make one of these. Anyone done it?
New addition to the stable. A few hundred bucks that appear well spent. Still only messing around with the signal generator, but it's promising. #electronics #oscilloscope

Trying to look at a signal in two time scales. I'm varying the output with PWM, but also turning it on and off, so it would be neat if one trace was on the 2μs scale and the other was in the 2s scale.
I guess that's not a thing on my Rigol DS1102E. Do the fancy scopes do that? I could look at the slow scale on the logic analyzer, but I didn't need it bad enough.

Recently, I intentionally bought a broken oscilloscope to have some repair fun. And today it paid off! I identified the defective transistor and found a suitable replacement in my inventory. I am so happy! The oscilloscope is from the 70s and all the documentation can be found online. Including circuit diagram, PCB layout and so on. #openhardware #righttorepair #oscilloscope #repair #transistor

It's finally back from the dead! 500MHz 'not working, for parts only' #Oscilloscope from ebay will live to debug more #electronics projects. In the transition from 'not working' to 'working' it also got a new 64 GB SSD hard drive and a whopping 512MB memory upgrade. The UI now runs without any lag when navigating the menu.

Power rail probes are a handy #oscilloscope accessory, because they let you apply a voltage offset before the signal hits the scope. This allows you to look at ripple on low-impedance, highish-voltage power rails.
Commercial versions are _expensive_ (https://www.keysight.com/us/en/product/N7020A/power-rail-probe-2-ghz.html). It turns out they're not wildly complicated, so here's an #OpenHardware version.
Naming things is difficult, so I called it 'power rail probe'. Lots still to do: feedback welcome.

A week ago, I was troubleshooting whether my #Quad 306 amp was faulty.
Being a test bench noob, I set my signal generator at too high a voltage on one input channel. The amp made a 5kHz squeal and happy smoke emitted from the circuit board full of lovingly hand-placed 40 year old components.
I immediately shut it down.
There were no obvious toasted components.
Enter a week of researching proper test techniques and test equipment for such tasks.
Drunk with a bit of newfound knowledge, armed with schematic printouts, a multimeter and an #oscilloscope, tonight I thought Id try to deduce the problem.
Power on (no input), checked the voltages at various places on the board suggested by the schematic. Everything was curiously in spec. Re-checked the outputs - no unwanted voltages.
Hooked it up to the 'scope, and placed some (proper volume!) audio signals. Clean sine waves(!).
Ok.
Let's hook this effer back up to some speakers and see what we have.
AND IT WORKED.
The happy smoke must really have been the essence of harmless English fairies escaping.
Now, I've got an old variac and some test leads on the way from ebay, which may be un-needed.
That definitely looks like good video on the oscilloscope. It changes a few seconds after power on just as you'd expect with a working spectrum after it completes the ram test so I think this unmodified machine is working.
I'll need to do a mod to get composite video out of it. #retrocomputing #oscilloscope
Wait. I *think* this should already be working? Maybe it's actually a latency problem?
I need to figure out how to trigger my #oscilloscope on the region in question. Slope or width or something should do it.
What oh what can fill those empty shelves?
Feast your eyes on this coworker castoff! No idea if it works, but at ***$50**** I'll just consider it a ticket to a fun couple evenings finding out.

This is one of those: figuring out which stuff is actually still working afternoons. It turns out: my #oscilloscope is working, my #ft817 and my swr meter and my dummy load works, too.
My #ma12 trx which I wanted to test, in the first place is in desperate need of calibration. But, same goes for my KX3 and K2 #tranceivers which I took to cross check first. It took me a while to figure that out, wonder what comes next.

A plumbing accident caused me to pull out some of my older home-lab #electronic #testequipment. This #Tektronix 7904 was my main home #oscilloscope from 1995 to 2005. It still works! When I was an undergrad #physics major (1976-1980), scopes like this were in every research lab, so when the prices got low enough on eBay, I had to have one. I love the tiny lighted buttons and the character display. The mainframe has 500 MHz BW, but these 7A26 vertical amps only go up to 200 MHz. #electronics

I got to use a hantek6022bl USB #oscilloscope with #openhantek and #sigrok #pulseview this week and I immediately sold my analog oscilloscope and I'm going to get one.
Its so convenient that it can fit in a backpack and is compeltely powred over usb. It also has way more features, like fft and math etc.
The fact that there are powerful open source drivers and software also eases my mind about software support since it has no screen and relies on the computer for output.
Somebody tell me which #oscilloscope I should order from RS components UK as somebody who wants to do some basic synthesiser building/design. Very basic. Noob level. I don't know jack about oscilloscopes..
The Bluetooth serial module HC-05 seems to work fine. But I had trouble connecting it to the Arduino Nano (clone) via software serial. Good to have an oscilloscope to debug which pins the signal is actually being sent from and what baud rate is actually used (bad documentation).
