Hi I'm a postdoc in biology and just stumbled across this as I was thinking of ways to use electronics to help automate things in the lab. This is very neat and impressive, keep it up! I look forward to seeing it in action. What is your background by the way? If you're interested I was thinking of playing around and maybe building a PCR (for fun) and, more practically, a 96-well plate auto-washer (for those laborious ELISA wash steps -- basically it's filling the wells to the top, usually 400ul, then vacuum sucking it all off, repeat 3 times). I bet you could do that, maybe offer me some tips if I do try it? I have some experience coding with the PicKit but was thinking maybe the Arduino is the way to go in the future.
Thanks for sharing your creations!
