I have one of these: SparkFun Tiny AVR Programmer PGM-11801. I was thinking of getting another one or two for backup, but there’s probably no need at the moment.
Also I figured out how to put a programmer on my Pluggable ATTINY Development Board For ATtiny13A/ATtiny25/ATtiny45/ATtiny85 Programming Editor Micro Usb Power Connector (see that link for details).
Here are two options for semiconductor analysis:
Also available in kit format: ATPK3 – Atlas Pro Pack – LCR45 + DCA75 + Case with the LCR45 – LCR Impedance Meter.
This isn’t super high quality content, and is basically just advertising, but what the hell. I’m not sure how regularly they get new content, but today on Maker Hub:
I found www.ldelectronics.com.au. Might try them out for PCB manufacture.
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.
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).
This dude’s web site is fun: hobbydebraj. Unfortunately the link that took me there is 404ing now.
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.
