Re: Unusual Ammo and Barrel Construction

Update: it works! I’ll probably make a separate post with some more details, pictures, and videos. Thank you to everyone for the inspiration and ideas, I almost forgot how satisfying a successful launcher is! It’s a simple concept, but somehow so unique and quirky

Re: Unusual Ammo and Barrel Construction

Update: I no longer know how to post pictures properly, but I’ve made progress on the build https://imgur.com/gallery/PcKwkWa Here’s an album of some detail shots of the barrel. All the parts are printed in ABS, but aren’t holding any significant pressure here. I won’t add the fillets into the barre...

Re: Unusual Ammo and Barrel Construction

I ordered some parts today, and I think I have a pretty good plan! The Co2 system and 3-way valve have been working well, so the easy part is out of the way. For the barrel, I ordered some rectangular aluminum tubing 5" wide x 2" tall. This should fit most of the bagels I have in mind, and to create...

Re: Unusual Ammo and Barrel Construction

Thanks for the inspiration! I've never truly left, but I got a serious engineering job out of school and that's moved me into an apartment and diverted my attention towards some more electronic/computer projects The more I think of it, the better a "frisbee" orientation seems to me, as far as the qu...

Unusual Ammo and Barrel Construction

Hi all, I’ve been away from the forums for a while, but have definitely been tinkering with some old and new projects! I’m back asking for thoughts on an interesting design challenge I’ve been given. I’ve been asked to design and build a launcher that shoots full bagels... Now naturally, I could sho...

Re: "In the world of spuds today"

Thanks JSR! I didn’t expect anyone outside these hallowed halls to see it, but the single random commenter gave me a little bit of hope. In the “decline” of this site’s activity, I think socially minded image hosting sites like imgur may be a helpful resource to draw in some curious new members. I a...

Re: "In the world of spuds today"

I haven’t been active in a while, but I’m still here! Decided to throw together a simple, efficient, and solid launcher for old times sake. https://imgur.com/gallery/Rh9HwLA I’ve also just purchased a lulzbot mini for some 3d printing projects for my other hobbies, but I hope to find some more “dest...

Very cool,

Do you have a link for where you got that co2 regulator?

Re: Noise cannon for RC planes

I've been messing around with those Venturi nozzles for hybrid fueling, and I think I've got an idea to at least help your rate of fire issue a little bit. If recommend finding or making a very high flow Venturi nozzle and suitably sized "initiator tube" with a constant spark inside (like a taser ci...

DIY Electric Bike Conversion

So I've got some free time this summer, and I wanted to make an upgrade to my worn out mountain bike: So basically, I usually only use it between classes or on smooth pavement around town (ranges less than 5 miles generally) so I wanted to try my hand at a cheap and effective modification to convert...

Re: Pneumatic Golf Ball Gun

Very cool rendering and very creative design! ...but, I think you are definitely over complicating things. I recently made a golfball gun for a family friend to replace his driver (which he can no longer hit due to a recent procedure) and even with a 1" by 10" chamber feeding a 3/4" QEV to a 24" bar...

Re: Backpack air supply project.

If you're having issues with low-flow from the regulator, why don't you put a small accumulation tank between the regulator and the gun?

Re: Arduino Start-Up

Exactly, I've had about a month of playing around with some components at school, but I want to be familiar with what range of things I can realistically accomplish with the board so that I can zero-in on what sorts of things I really want to pursue with it. And until I get comfortable with it, I do...

Arduino Start-Up

Hey everybody, I've been away from hobby building for a little bit because I've been busy with school, but now that summer is just around the corner, I want to start with something new. In a beginner engineering program at my highschool, we started the basics of arduino. I really liked the projects ...
