Just finished my stripped Teensy 1.0, made on a Prototyping Board. And it works I had to modify my printboard layout slightly, to make more rom for the crystal, and the switch. The soldering of the IC whent smoother then i had expected. The legs are very thin, and breaks easily with a wire attached to them... So after i had solderd all the wires to the IC, i dipped it in super glue.
I used the BAT54C Schottky diode, and its a SMD, so its wery small. I could have just used two regular Schottky diodes. I also soldered the usb cabels shielding to the print board, to take the stress of the usb wires. Also "made" a housing for the board, from somthing i had inn my back pocket
I didn't get it to work in Win7, it wouldn't accept the drivers. Works perfect in XP. I used Flip to do the flashing, and the teensy 1.0 hex file.
