I wanted to try if a 100% DIY process to reflow a small batch of boards. For about 10 boards it is cheaper to hand solder them than ordering a stencil, but I was wondering if it can be faster to manually cut a stencil and reflow the boards on a frying pan.
A friend of mine asked me for some help on an Akeru device: it is an Arduino + Sigfox modem.
After a few tinkering, we succeed to do what he wanted and share it: gather some sensor data and collect it in a PHP webpage. The Arduino code is quite easy thanks to the Akeru library, but Sigfox callback is a bit more tricky. The callback will be parsed by a PHP script on my friend’s server, but I also played a bit with it to able to use ioPush, my IoT logger/push notification server.
Thanks to Let’s Encrypt program, we can now generate free SSL certificates. I used the beta program with success, but now I want to use it on another server running through HAProxy. This is a trick to combine certificate, chain, and private key to be loaded by HAProxy :-)
