Printed Circuit Board Manufacture
I found www.ldelectronics.com.au. Might try them out for PCB manufacture.
Silicon Chip
I think I’m gonna subscribe to Silicon Chip magazine. I’ve ordered the October issue in print format and the September issue in electronic format. Might get a 12 month print & digital subscription starting in January next year.
What You Really Need to Know About Sample Rate
I found this PDF explaining sample rate considerations: What You Really Need to Know About Sample Rate. It’s mostly about how aliasing works and what you can do about it (employ an anti-aliasing low pass filter or oversample by as much as 10x).
hobbydebraj
This dude’s web site is fun: hobbydebraj. Unfortunately the link that took me there is 404ing now.
Talks by Roland Turner
I was reading HATS: Automated testing of homebrew amateur radios and I discovered this list of talks by my mate Raz.
Rigol MSO5074 HDMI
I got my Rigol MSO5074 outputting to HDMI:
I can’t get it to work on my bigger HDMI monitor though, not sure why. Maybe the cable is too long? Maybe the signal is too low resolution? I don’t really know enough about HDMI to guess at the cause.
// 2022-09-18 jj5 – UPDATE: according to this there’s a known issue with HDMI that’s fixed with a firmware upgrade. Might have to look into that.
Rigol DK-DS6000 Oscilloscope Demo Trainer Board
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.
