The PEST BB machinegun...

[pest3125]

Hi,
This may be old news to some, but I recently completed a "centrifugal" type of BB machine gun. Its more powerful than most airsoft guns.

Ok, Ill bite.

How much and where?

Sounds similar in concept to that DeWalt looking Russian BB gun. If those stats are correct, you need to find a manufacturer ASAP! Have you patented that design? If not, do so now.

I'd buy one if the price were right

I'm always tickled pink to see do it yourself projects turn out as nice as that.

I am not planning on going into production - it was just a fun hobby project for me. Patents are mentioned on the webpage - there appear to be 2 relevant ones - both have expired, so the design is in the public domain, as far as I know.

Thanks! I did it just as a "proof of principle" for larger versions..

Larger, you say?

Sir, I am intrigued by your ideas and would like to subscribe to your newsletter!

Finally a working rifle that kinda looks like an HK G11!
Very cool, sir, very cool.

That's delicious. If you develop one that takes detachable magazines and "standard size" pellets and such, I'd be there like shareware.

How much for you to build? Also how long??

A larger version could possibly deliver lethal energies, but it would require heat treatment of the launch mechanism.

I built it using a Sherline 5400 tabletop milling machine. That's a manual mill, so it takes some time to make the parts. From start to finish including design time, it took probably 1 year of calendar time to finish (not working full time of course, since this is just a hobby)

Neat little gun!

Questions:
What are the electronics?
Is that a PIC processor?
If so, what language did you use to write the code?

 

[pest3125]

# What are the electronics?
The electronics handle turning on the motor and activating the solenoid to feed balls into the launcher

#Is that a PIC processor?
Yes, the PIC is a microcontroller made by Microchip Technologies. Its very popular among hobbyists. I am using the 14 pin flash version. The simplest version has only 8 pins and the largest, more than 40 pins.

#what language did you use to write the code?
The code was written in assembly language

 

[MarshallDodge]

Neat. I have programmed a few Microchip PIC's in the past.

I used the Microchip assembler-MPASM and Parallax's assembler -Pic51.
Parrallax's assembler was nice since I was used to the Intel 8051 architecture.

I have a similar idea in mind but using a linear motor instead.

I want one.
