I have some red leds left , should be enough or 3-4 boards.
These are real vintage leds that are pulled from Ti calculators of the same generation as the well-known Exactras.
Boards are from Slothfurnace. I currently have some blank boards - 2 blue and 1 from each of the other colors.
I'm offering this as a built to order - let me know what color board you want and I'll solder the LEDs in a day or two and send you a picture of the completed board, and you only pay if you like it. In case I'm out of boards for your prefered color - I can order one from Slothfurnace for no extra cost for you, but of course it will take little more time.
Price is $170. Shipping in US - I recommend USPS small flat rate box for 9$ for the extra padding. Contact me for other options.
