Hi all,
I need a little help with my next non ReefPi related project. A while back I built this little fire/security hazard:
It’s a battery powered (2x2000mAh LiPo) self heating mug with WiFi Interface and a small OLED screen.
Now I want to bring that project to a better state, since the DS18B20 temperature sensors died on me and the whole thing is kind of falling apart
I’m planning to build something more compact into the bottom of a double walled steel mug, using a designed PCB, SMD components and a 3D printed housing. I’m also planning to exchange the DS18B20 sensors with NTC resistors, either in a resistance bridge or with OP-Amps and a self calibration routine.
First things first though:
I think I would like some advice on PCB designing with SMD stuff, e.g. what programs and manufacturers you use ( I’m planning on having as much pre-soldered as possible) and what to look out for.
I’m appreciating all the help I can get, since this will be my first .
