I recently got my first generation PCB in the mail from OshPark and I’m happy to say that the board works just like I had planned! I was able to do some basic testing using 10,000 step encoders, but due to the power of the Teensy 3.1 board and being able to use interrupt driven decoding there shouldn’t be any problem handling 100,000 step encoders if you so desired. The good news is that the board did a great job of reporting the position of the encoders to Sky Safari Pro running on my iPad via a wireless WiFi connection!
Renderings of the board I actually ended up using:
Photos of the board with the necessary components installed:
Notice there are some missing parts on the PCB. Â That’s because so far I’ve only soldered on the parts necessary to power it via USB. Â The missing parts are for powering it via 12V DC.
It also fits nicely in this small plastic enclosure I have:
As you can see, this board is smaller and much simpler then the earlier board I designed. I did this because it wasn’t going to be possible to fit the original board in the small plastic enclosure I had picked out and most of the features I wasn’t actually going to use/need and I wanted to focus on getting the basic DSC features tested and working.

Thanks for this great job. I am really interested to build mine. Do you have some details on how to do it (components, drawings, program, …).
Many thanks for your help
Thanks Aaron for your reply, where did you get your main board ? Or maybe do you sell some fully built ?
Instructions are on the wiki: https://github.com/synfinatic/teensy-dsc/wiki/Building-your-own-Teensy-DSC
I may have an extra PCB laying around I’d sell for a few bucks- I’d have to look in my pile. I’m no longer offering to sell fully populated boards since I’m in the (slow) process of designing a cheaper solution using the ESP8266: https://github.com/synfinatic/esp-dsc
Well in fact if you have any other type of fully populated board for sell, I am interested.
If not let me know which spare parts I can order from you.
I don’t have any fully populated boards for sale, nor do I plan to do so in the near future. I’m in the process of redesigning the ESP-DSC board because it can’t keep up with higher resolution encoders, but I expect that to take a few months due to my busy schedule. What encoders are you planning to use? I’m pretty sure I have a first generation ESP-DSC PCB laying around somewhere.
Do you think the CUI-AMT102, should work ? It is capacitive encoder, not optical.
