How do you move a 0201 on a Raspberry Pi Zero W? I have the area kapton taped off (so I can apply selective heat without everything on the board blowing off), used hot air and flux to remove the zero ohm resistor, but now I’m having trouble figuring out what combination of hot air and soldering iron will get it back in place. (I don’t think I can apply solder, I have the smallest filament I could find but its too tiny for that.)
tldr: Getting my butt handed to me by a 0201. (Have done 0402 before.) Keep in mind the Raspberry Pi Zero W is a board about the size of a stick of gum and a 0201 resistor is like a quarter the size of a flea.
Also, has anyone used a RHF0M301 with a Raspberry Pi Zero W yet?
edit: After watching other people struggle, the plan is: dab solder paste if the area is still bare metal, place the 0201, then use hot air and hope for the best. https://youtu.be/iKr1FeHgd4I?t=11m41s
I ordered a Pi Zero W for an diy wireless alexa thingy and did not realize (until now) that you don’t have an external antenna connection so I can’t put it in a metal enclosure.
I’ll follow your struggle …
for voice recognition with RPI I’m struggling with a (cheap) good mic input/output, @ the moment trying with an sony ps3 eye
Hi @BoRRoZ and everyone…
Nice topic started.
I tried out the ‘speechrecognition’ package in python. Works like a charm. But in your case is voice recognition different from speech recognition ? I think so !! ??
you’re right, I’m not after recognizing specifically my own voice or accent … just building a diy personal assistant and looking into ‘voice controlled applications’ with open source packages / SDK’s
I’m waiting for this MIC amp module and this DAC module trying get better audio out and in.
best would be a mic array with a dedicated dsp like this one but digital mic’s are still expensive.
another idea is to let a mic/camera follow you in a room
a really cool example of this technology in a diy project :
Thanks, yup got it working - sinking in conflicting lora libraries - plus the DIO1 needed connecting up - nice board, need to do some sleep testing later too
it was my first ABP test for this 32U4/RFM95 china adafruit feather clone, just to see if I didn’t make ‘key’ mistakes
code example is here and here
not much free memory left so what we need is an 'stripped lmic version to gain some memory.
the goal is to send temp and humidity data and we need deepsleep.
regarding the battery voltage (drop) , I didn’t even check that code part/pin … was supprised it measured anything
one thing I noticed immediate, on first boot with a piece of wire antenna on my desk … the packet was seen by 3 gateways, even the one 13 km away … I expected to see only my GW in the console.
that makes me wonder… is the output of the RFM95 that much better than the RN2483 TTN uno clone I build ?
have to check and learn a lot more.
