‘hidden’ 3v3 dc/dc converter Pololu S7V8F3


it’s alive


little programmable packet generator

you can change the backlight color by changing led’s
searching for info on libs and wiring you come across tons off nice projects with this cheap display.

new stock of dupont cables arrived … I was always short of the short male-male ones :sunglasses:


#262

the LoRaWAN metaldetector frontend kit arrived :wink:


not to complicated for a sunday


conclusion : it works, if you want to detect big metal objects from a 5 cm distance :sunglasses:


(Dave Thornton) #263

Just built one. 5cm in free air perhaps. :slight_smile:


#264

so defenitely not usefull for detecting parked cars :wink: (or finding gold nuggets)


#265

found some rotary’s and some nice big, but low, rotary knobs


The Things Node : new low power library development
(chaolue) #266

I know I’m replying to a rather old message, but thought I add this in if someone else was having trouble getting lower power use out of the BSFrance Lora32u4 II

After struggling to get anything below 200 mA, found the Arduino IDE board library provided by DiYMall must have been wrong or old. Downloaded one from BSFrance website with much better success with LowPower lib. There may be hope to use it as a battery powered node after all.

Waiting on a new multimeter to get more accurate results.


#267

thanx I will try :sunglasses:
(can you meassure it powered from a battery/lipo) so including the dc/dc circuit


#268

did you also burn the bootoader from bsfrance?


(chaolue) #269

Slightly less with via battery.

Also, didn’t burn BSFrance bootloader. Assumed they were identical.


#270

I really don’t understand this but he, its 20x better then my lowest find and very acceptable for a battery powered device (its not 50 uA but ok :wink: )
