I need a tally counter for creating donor sites during hair transplantation surgeries. I need the schematics and code, since I don't have the time to work on them, but I can build the device myself.
Basic functionality: The patient has an electrode (ECG electrode) on his hand. The other end of the wire is connected to a needle used to create donor sites on the patient's head. When the needle cuts through his skin, the circuit is closed, the device makes a sound (beep) and 1 donor site is added on the counter (of course it's displayed on a screen). The counter should be battery-powered and have a reset button and power switch.
Additional function ideas – not necessary – I will choose them depending on price:
– a distinct sound for every 100th site created
– a small message above the counted sites like: "Donor sites created:" "1247", maybe even with language switch button
– "+" and "-" buttons for manual control
– I don't know if this is possible, but adjustable sensitivity would be nice (so that it only counts when the needle actually goes through the skin, not just touches it)
Please send me your quotations :)
