While watching TTT367 Embedded Systems and Rigol MSO5000 I learned of the Rigol DK-DS6000 Oscilloscope Demo Trainer Board which are for sale for US$231.

Constant current electronic load
Before I splash out the big bucks for a DL3021 (or similar) I might start with a much cheaper option (there is also a case available).
Rigol DL3021 Programmable DC Electronic Load
I want to get a programmable electronic load. There are a bunch of options from Rigol. I’m thinking maybe a DL3021, such as this one available from AliExpress for $742.58 + shipping. Should probably do some research and see what is available from other manufacturers.
YouTube channel: tomtektest
So I found tomtektest on YouTube. He has a series of videos on the Rigol MSO5000 (which is my scope).
Approximation of a square wave
I was reading Fast Fourier Transforms explained and I wanted to play along…
This code uses sine waves to approximate a square wave. The first is to the 11th harmonic, the second to the 9,999th…
The Electronics Workbench: A Setup Guide
So I recently completed the Udemy course: The Electronics Workbench: A Setup Guide. It was just some good introductory fun.
After watching the course lectures I decided that my electronics lab could do with a few more potentiometers, but apart from that, I already had most everything else.
I would like to get a better set of helping hands, though; the instructor had some nice ones which could be repositioned along the horizontal axis, but I can’t quite find such things on eBay.
Also I’d like to buy a desoldering gun, but I don’t have the funds just at the moment.
Most of the tools and parts recommended in the course are listed over here, but not those specific helping hands and not the desoldering gun (I’ve sent a message to the instructor asking about those two things).
I’m planning to buy these helping hands in the near future, assuming I don’t find something better.
Pico Oscilloscope Range
I was searching for oscilloscope application notes and ended up finding the Pico Oscilloscope Range. If I was in the market for a PC based scope (I’m not) then I’d probably check these out. There’s some cool equipment there!
(Note: my MSO5074 scope has 8-bit vertical resolution, which is fairly standard, but if I ever find myself needing higher vertical resolution I will check out the
PicoScope® 4000 Series high resolution oscilloscopes.)
While checking out the Pico Tech site I found some other interesting articles:
- What to look for when choosing an oscilloscope
- Debugging an I²C bus with a PicoScope mixed-signal oscilloscope
- Fast Fourier Transforms explained
- Measuring the frequency response of a loudspeaker
- Colossus: we connect a PicoScope to the world’s first computer
And I also found Common Oscilloscope Applications.
