Must be familiar with RFID, the proxmark3 system and T5577 IC chips. We are looking for a custom programming package for the proxmark3 system to be designed that allows us to sequentially batch program a specified number of cards. The formats needed are listed below and need to be programmed to the Atmel T5577 Chip. Well documented command-line programming is fine. We also require there be a OTP lock function while writing to the blank cards. Formats HID (r) Prox (r) 26, 37, 40 bit AWID 26, 37 bit Keri PKT Indala This link may help understand the layout of above formats:   [obscured]  /forum/viewtopic.php?id=1767 If done successfully, there will be much followup work.

I am working on a device that I would like to control via an android? (touch screen interface). It is an air bladder that would be controlled by a pump that would regulate/display pressure. I will need a separate control for temperature and possibly a flow readout. The temp and pressure are the big ones. I envision these read outs on a small touchscreen interface. Pressure control: 0-175mmHg pump Bypass valve to keep pump from cycling? Control to Reverse pump to deflate bladder Touchscreen for "set" value- readout for "actual" value Temp control: Temp control for 120v 200W heater 98-102F Touchscreen for "set" value- readout for "actual" value I can build this on a breadboard but I am not sure what controls I will need to communicate with the logical circuit- I have a variety of prototype parts that can be utilized and I have no problem getting other items if necessary. My budget for the programming is $750 not including parts. I assume there w...
