Lowest Possible Cost Mechboard64
Posted: Mon Jul 13, 2020 6:13 pm
While I regret never getting "the Rolls Royce" version of the Mechboard64, I can say that confidently that a fully functional, cheap and cheerful version should be easily buildable. I have started the process and it is looking good, and cheap!
Here is my cost breakdown so far:
To be fair the price of the PCB does not include shipping. I ordered the PCB with 25 other PCBs I was having made and the DHL shipping from China was $30 for all of them, which is a little over a dollar per PCB if you want to adjust the cost to be more accurate
The lowest cost key switches can be had for between 18 and 25 cents each, so I expect a maximum cost for the switches to be around 18-20 dollars.
Also note that the plate will be flat, not bent, so I have to figure out a mounting solution.
I noticed that the C64 keyboard uses a flat, 20 pin cable, meaning I should be able to use a standard 40-in IDE ribbon cable!
Still going to be several weeks until I have time to solder it and work out the kinks.
I have a couple extra PCBs and sets of surface mount components if folks would like to try and build their own.
