Thanks for sharing and your quick response! What a great resource!!!! I was looking at the Alpha website yesterday and there is a new 3 phase endless pot called the RV113FF. Requires another ADC read per pot but has a very nice symmetrical output characteristic with respect to angle, which...

I was wondering if you could share some more about the polling of the 360 Pots. I am working on a project and considering using these. I noticed that there are 2 analog outputs per pot (to help smooth over the dead zone), so you are using 12 channels of the mux? How fast are you polling /...

Thank you Rolf for the schematics! I found that the TFT CLK was not connected. There was a bad solder joint on the T41 header. It Is fixed now and the screen works! Also headphones work on the DAC board so I am able to hear the synth play notes from a MIDI controller (the NDLR). More testing...

Can you give URL for schematic, the web site URL retrieves 404? Or tell me the pins that connect the T41 to the 7735 screen so I can test for connections or shorts? Thanks

Note: the 2N3904 transistor was missing (or I lost it) and was replaced with PN2222. http://www.learningaboutelectronics.com/Articles/2N3904-vs-2N2222.php

Thanks for all the kind replies! What power supply do you have? 12v center positive 2A Than, all voltages are ok, means 5V, 3.3V, +8V. this is ok ?? Yes Remove the FX Board. Than test all voltages again. No FX board attached. I bought the complete kit. yes I had the 10u tantalum cap in...

Hi Rolf, (Sorry I don't speak G e r m a n) Is this the right place to get technical support for the Jeannie HW synth? I'm have some issues: 1) I don't measure -8 volts. Are there debug steps or tests points to try? The voltage pump IC is in the socket correctly. 2) I installed firmware...
