"They're the same picture." #electronics
Electronics nerds, my son is getting into building electronics. He's become a dab hand at soldering and wants to try out surface mount stuff.
So this Xmas I'm gonna buy him a little workshop setup. Pinecil and power supply, fume extractor, helping hands, other odds and ends. Some components to get him going.
But question for the #electronics #makers on here: is there a reasonable way to reflow safely and cheaply? Is it achievable for a teenager at home?

Hab das Teil aufgemacht. Sie haben den Glättungskondensator weggelassen (aus Kostengründen?), was die Lebensdauer der LED Pakete verkürzen könnte. Kann sein, dass der LED Treiber (SM2315E) das irgendwie kompensiert, aber das Datenblatt dazu gibt's anscheinend nur auf Chinesisch. #electronics

Oh boy, that was fast! Somehow we need to find more future-proof models for open-source hardware. Letting the market do its thing is showing its true colors once again. Pure evil! 👿
Hey #electronics folks, has anyone designed a board for a Quectel 5G WWAN M.2 card?
The M.2 spec says VCC typical is 3.3V maximum 3.6V, but the Quectel datasheet claims to want 3.8V typical 4.4V max. There’s claims in the Quectel datasheet that the card will shut down if VCC reaches 3.125V. It’s pretty power-hungry when the radio goes into transmit mode with 1.5A transient loads so it could possibly under-volt if I use 3.3V, but if I use 3.8V then the slot would only be usable with Quectel cards that demand the higher voltage.
Thoughts on 3.3V vs 3.8V in this situation?
In China, electricity can be "weak" (= electronics engineering) or "strong" (= electrical power / HV engineering). I thought it was a Chinese invention until I saw an English paper from a Russian author with an affiliation to a "weak current" research lab - turned out to be another case of "copied from the Soviet Union." USSR itself apparently also copied it from Germany (Norbert Wiener, Cybernetics page 56). A living fossil of a specific WW2-era technological transfer path that no longer existed. #electronics

New capacitors have arrived!
I was beginning to miss the most common values found in audio equipment from the 80s and 90s 😅
