MiniGun Supergun open source build?

[funk]

Interested to hear if anyone has whipped one of these together at all?

One of the many projects I've got sat on the ever growing back burner of "I'll get around to it one day"

I own one but didn't build it. I made the mistake of using the LPF switch while it was powered on, which blew an IC. I replaced the IC, but should be a jumper rather than a switch, IMO. But it's open source to so you can fit what you like. 🙂

I have made one. What do you need to know?

Fair question! Just any gotchas and safe improvements you could make like @big10p suggested 👍

Edit - @big10p just noticed the later revision it was swapped out with a jumper 👍

My thoughts on the MiniGun Supergun:

It is a very good supergun and probably all you need.​

It's not cheap to make if you don't already have any of the components. ​

It involves some SMD soldering, most easy but the THS7374 requires some careful drag soldering and a good check over under magnification to check none of the legs are bridged. ​

The initial jumper settings can be confusing but the info is all there on the mega post on Arcade Projects forum.​

You can make a 3D printed case which makes it much more robust.​

I used a spare power lead from modular PC power supply as the power lead, a neat solution if you have one.​

There are two versions mini din 8 and mini din 9 dont source the wrong socket like I did.🤦‍♂️​
