What's involved in making a Sega Genesis reproduction game cartridge? We'll look at the full start-up cost for both basic cartridges and SRAM battery backup cartridges. What programmer to use, EPROM types and sizes, byte swapping the ROM, customs PCBs and shells. We'll be making PCBs from essentially scratch; therefore we do not need destroy/sacrifice a factory game to produce a new reproduction game. It's the right thing to do ;)
We'll also look at options and alternatives for cartridge shells.
The PCBs are open source , remix, order your own!

![Pandoras Box 5S [bootleg], 2-player Arcade in a Box | Review
With 1300 games stuffed into a 2-player control panel, how is the experience for coffee table arcade gaming? Im looking at build quality, design, UI experience and overall gameplay presentation.
In summary: its meh.
The game list is too long to put in the desc; so Ive posted it on my website here: http://www.retrobuiltgames.com/reviews/pandora-s-box-5s-cp/ Pandoras Box 5S [bootleg], 2-player Arcade in a Box | Review](https://i.ytimg.com/vi/mmGhPJ-hjps/mqdefault.jpg)




![Automatic Small Part Counting Machine with Arduino | Version 2
I rebuilt my small parts counting machine into a smaller form factor with a better mechanical separator inspired by Rx pill counters. I [used to] sell kits with small parts/fasteners. Counting them by hand is time consuming. I made this robot to do the task.
I consider this endeavor abandoned- but enough people find this video and ask about the design files so everything is open source now.

id love to revisit this. please share what you make. this solution done cheap will help so many people. Automatic Small Part Counting Machine with Arduino | Version 2](https://i.ytimg.com/vi/r7ZmXTTQmEo/mqdefault.jpg)
