Sorry for the lack of posts but my adventure into the world of CNC machines took me of at a slant so here is progress on the two projects. (Also no one is commenting so i don’t know if anyone is actually reading this or whether i am just wittering into the cyber darkness.)
Almost all written and just waiting for a PCB to be made and the last little bit (the electromyography bit) to get working. I’m attempting to build an EKG to start with since that’s easy for me to test and then i will just change the probes and the software for the final version (and possibly the gain of the input amp) The PCB will hopefully be made on my nice shiny new PCB router once i can get it working. It does a very good job of ploughing all the way through the board or just compliant at me at the moment. The breadboard prototype is now looking like this and there’s more to add (also just noticed that the serial port 9pin D-sub has fallen off in that pic but it shuould be hanging off the MAX232 there) . Most of the parts for the beta model have been bought including thisrather swanky box (the red one) which requires holes to be made in it for controls which will hopefully be done with my Boxford Duet now that i have finished the first attempt at the software.
Its all still moving along. It will be finished one day….
