For soldering components, we also use a fully automated process. The PCB is put in our autoplacer robot. First, the robot gently injects one or more drops of solder paste on each pad where a component has to be placed, using a small motorized syringe driven by an Archimede screw. Then, it picks all board components one by one from a reel or from a tube, and places them at the right place and in the right position.
The number one fantasy among DIYers is probably hacking the coffee machine to remote control it. We thought about this for many years. Today we finally decided to do it. Meet Josephine, our coffee machine, an old JURA IMPRESSA F505 model.
The most difficult part was to dismantle it. Obviously, the guys who designed it did not want us to have a look inside. There is almost no screw: all parts are clipped-in.
Building a USB device to drive the shy red led everybody knows would probably be a big overkill. At Yoctopuce, we are not really afraid of overkills, but there are some lines we are not willing to cross...
Anyway, driving one of these shiny little color leds might be more interesting: driving directly one of those is not so easy if you want to create the intermediate colors.
When it's hot like today, a fan is kinda cool, but a USB fan is so much cooler. So to build a USB fan we need: a basic fan bought from the nearest appliance store, a Yocto-PowerRelay, 15 minutes to properly install the device in the fan, some more time to code a nice web page to control it, et voila! a nice USB fan remotely controlled from your desk. Have a peek below...
