It is an electronic membrane feeder for nursing mosquitoes for egg production. it heats sheep blood between 98 and 100 degrees F, the mosquitoes penetrate a lab wax or intestine membrane to feed on blood. I can heat and monitor up to 4 feeder/heater heads and display the calibration temperature VS current measured temperature. it Requires about 20-30 minutes warm up period for thermal stability. It is currently in testing phase and successfully feeding mosquitoes, still have some "bugs" to work out such as feeder head dimensions, blood capacity and filling methods.

With this schematic the MCU supply is 4.5V, if you want 5V the zener must be 5.6V. That's it.

I actually used a 6v3 zener, not sure why i put 5.1v in schematic, measures 5.6v.

I know there are CDC scientists that would be thrilled to have one of these!

Once all the "bugs" are worked out, I will submit schematics, diagrams and code here so they can build their own.  i am not sure the university will patent the feeder head design as it is not totally original, as i borrowed some aspects from an ancient  broken Hemotek blood feeder, and the micro controller is open source, but if they do patent it and manufacture it, i will certainly post a link where is can be found.
