A DIY-Kit for the KeyPass USB password manager. SMD soldering (0805 resistors/capacitors and the ATMEGA8 in TQFP32) required!
If you don't have a ISP programmer or don't want to solder the ATMEGA8, I can ship it with pre-soldered atmega, crystal and two capacitors and also pre-flashed with the V-USB bootloader so the final firmware can be easily uploaded via USB.
1x USB-A jack
1x SC56-11GWA 7 segment display
2x 3,6V Zener diode (D2, D3)
2x 68 Ohm 0805 resistor (R2, R3)
1x 2,2 kOhm 0805 resistor (R1)
1x 10 kOhm 0805 resistor (R4)
1x 470 Ohm 0805 resistor (R8)
2x 22pF 0805 capacitor (C2,C3)
1x 100nF 1206 capacitor (C1)
1x 16 MHz SMD resonator
2x right angle tactile switches (6x6mm)
See the Hackaday Project for more details and build instructions.
Original project description: This project provides a way of store up to 16 passwords, that can be sent to your PC like keystrokes. It was inspired by USB Key Generator by Code & Life, and therefore is also based on AVR and V-USB. One pushbutton is used to select the desired password, numbered (0-9,A-F) visible on a 7 segment display while another sends (types) the password as keystrokes. The button operation can optionally be performed by Num Lock and Scroll Lock. The Board was designed to fit inside a 1x1 inch circuit board and has a hole for being held by a ring on a keychain.
This kit is RoHS 2 compliant, so please also use lead-free solder to protect our environment (and your health!).
I build some of them and had parts left for more!
