This is a blank PCB only for building a Manual Prom Programmer for 82s123, 82s23, 74s288, and 74s188 chips. This programmer is designed to be powered from a PC power supply or arcade power supply with 12v and 5v lines. Assembly requires soldering and basic electronics experience. This sale is for the Board ONLY! You will need to purchase all other components separately. See the link below for a video, more pictures, and complete parts list below for a list of components that you can buy at Digikey, Ebay, and others. https://bsgelectronics.com/a-manual-programmer-for-82s123-and-82s23-prom-chips Feel free to send a message with any questions about this board, assembly, or use. NOTE – Please notice the orientation of the blue buttons when assembling this board. Programmer will not function correctly if buttons are installed backwards. NOTE #2 – PROM chips are one time write only. After building this board, it is advisable to test on an already written, “scratch”, chip so you don’t have to waste a new 82s123. *UPDATE* Version 1.5 corrects minor error and adds support for 74s288 and 74s188 chips. Note – To add support for these chips on v1.4 boards, change R7 from 4.7K to 1.3K and R11 from 91K to 82K. This will lower the VCC voltage from 10v to 9.2v and shorten the pulse time from 1 sec to .3 sec which works well with both 82s123/23 and 74s288/188.

Tesla Universal BMS Interface Board
This board replaces the DAQ board on used Tesla Model S/X Battery Modules. It simplifies the task of connecting any BMS to the Tesla battery module. This adapter board comes with clearly labeled universal screw terminals for connection to any BMS. Choose from Revision A, B, or C to match your Tesla battery.Tesla Revision A modules have 7 individual balance wires soldered to the board with a molded strain relief. Tesla Revision B modules have 7 individual balance wires terminated in a 15 pin connector Tesla Revision C modules have 2 ribbon cables for the balance wires, terminated in 2 connectors- one 5 pin and one 7 pin connector.How to identify Tesla Rev. A-B-C modules with photos: Battery modules from Model S and Model X cars come in several revisions, known as Rev A, Rev B, and Rev C. They look very similar in photos, but the balance wire connections differ. Use this guide to identify your revision. Revision A: Look for 3 groups of pins on the right. Revision B: Look for one row of pins on the right. Revision C: Look for 2 groups of pins, top and bottom.
Practice Circuit Board SMD Soldering Kit – Runway Lights
SMD/SMT Soldering Practice Circuit Board Kit -Runway Lights This is a board I designed for soldering practice. 147 items are to be placed on the board. 90 resistors, 5 resistor networks, 10 capacitors, 10 transistors, 20 LEDs, 10 diodes, one 555 timer chip, and one CD4017 decade counter/divider chip. A reference is on the back of the board to help with identifying the parts. Once power is applied, 2 rows of LEDs will cascade in a fashion resembling a set of runway lights. Contact me if you have questions or run into trouble. Note: this kit is not designed to teach how to solder SMD parts, but to practice what you’ve learned. Experience with soldering equipment is required. Thanks for looking. Check out my other kits! More to come…
Electronics Soldering Practice Circuit Board Kit – Runway Lights
Soldering Practice Circuit Board Kit -Runway Lights This is a board I designed for soldering practice. 47 item are to be placed on the board. 13 resistors, 2 capacitors, 20 LEDs, 10 diodes, one 555 timer chip, and one CD4017 decade counter/divider chip.

THT Soldering Practice Circuit Board Kit – Electronic Dice
Soldering Practice Circuit Board Kit -Electronic Dice Assembly required! A picture of an assembled kit is provided for reference only. This kit contains the THT version of the Electronic Dice Kit. There are over 70 parts to be placed on the board. I’ve updated the board to better show the proper placement of the chips and I’ve added the “ROLL” statement above the buttons. This kit is also offered with a shallow base and a premium base that holds a 9v battery. See other listings. Once you power it up with 9 volts dc (I’ve powered it up with 5 volts, just runs dimmer), press any of the 4 buttons to roll the dice. Once you let off the button, they will slowly come to a stop on random numbers. If you are new to soldering, I highly recommend watching some videos on the web. This helped me tremendously with learning different techniques (and relearning things I forgot). Contact me if you have questions or run into trouble. Note: This kit is not designed to teach you how to solder, but to practice what you’ve learned. Soldering equipment is required.If ordering more than two kits, I will issue a refund for any unused shipping costs that you pay. eBay charges multiple shipping charges of which aren’t usually needed.
