Serial DSC Board
FAR Circuits sells a custom printed circuit board, programmed PIC16F84 microcontroller chip, MAX232 chip, and 4-MHz oscillator for the serial version of my digital setting circles project.
Go to the FAR Circuits web page for ordering information and an order form. For the project description on the order form, use “Dave Ek Digital Setting Circles”. (If you look on his web page for a product listing for this board, it’s under the Miscellaneous category.)
Instructions for building the project using the PC board can be found on my construction page.
USB DSC Board
FAR Circuits sells a kit with a PC board and all board-mounted parts and connectors for the USB version of my digital setting circles project. The kit does not include the TTL-232R-5V USB-serial cable–that cable needs to be purchased separately and is available from Mouser and Digikey.
Go to the FAR Circuits web page for ordering information and an order form. For the project description on the order form, use “Dave Ek Setting Circle USB Interface”.
