Hello,
with such small packages, I was wondering what was the max temp to solder these?
the datasheet says the max temp these chips can handle is 150° but melting tin needs at least 250°

Hello,
I wanted to build a humbucker preamp, allowing me to learn JFET amplification in the context of electric guitars
someone pointed once this circuit to me
I was happy that it worked on firt try ,
but the gain is 1:1
I cant find any gain (hfe) like for bjt in the datasheet...
tried yesterday with epoxy and graphite...meh
I could maybe add some more graphite on top while it dries..but it will wash away
I found a formula yesterday, but some parts would be hard to find
I live in europe, so Elmer glue is like super glue or something ?
Hello,
I want to make my own game controler
so I was wondering, as I would etch the pcb, what is the black stuff they cover button contacts with ?
I mean I can order rubber buttons replacements online, but about that black dried conductive goo the put on the pcb where the button presses ...
no idea... just trying to follow this tutorial : https://www.instructables.com/id/Peltier-Cooled-Cloud-Chamber/
I'll purchase a piped cooler like the one he uses, this gotta work
I cannot power that pelletier module : TEC2-25408
Hello,
I have tried to power that pelletier module with an AT power supply but I reached max -10°C or something
so I ordered a 12V 10A power supply,
as I measure the pelletier module, it really does not go up to specs
barely -20°C (should...
hello,
I really feel like asking for the moon on google, but I have been digging for a long while, yet I am desperate to find an IC that rec/play audio with the least basic features :
- play/rec audio (couple of seconds of memory @44khz)
- receive a wav file, or whatever (RECENT !!!!) format...
Hello,
I use a 3.7V 16850 cell that gets boosted to 9V (board : https://www.aliexpress.com/item/32844818160.html?spm=a2g0s.9042311.0.0.27424c4dSXahMo)
as I sometime, have to recharge my cell, I thought I'd use 3.3V coming out of a LM3940 but the booster output drops to 4.4V while the output...
