Maybe you remember the ASCOM jolo focuser project – now it has the production implementation! Some of my astro colleagues took a chance and we made an action. 15 circuit boards has been ordered and 10 ready to use kits have been made. 5 other users ordered just clean boards to make the kit by theirselves. You can see how the device look like:

foc-4The reference solution uses L298 stepper driver and works with half steps by default. You can find all the documentation, schematics, source code and PCB project at . 


There were some problems with first revision of PCB thats why you can see a few wires around the Arduino board 🙂 

Clear skies!
