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 :-)
