Look at what just arrived
took nearly 2 weeks to get here though
For those of yous who don't know what an ATtiny is, they are essentially micro arduinos capable of executing simple programs. Now I can finally get on with this hunk of plastic and epoxy.

This is probably my favorite of all my videos:

A vortex would be amazing but I really don't think there is a place where I could use it. The only places where I can fly are my school's fields, and the official flying site in the video posted. I would probably get kicked out of both the minute anyone heard the BRAAAAAP of a bbmg. The crappy cross...

"There was this explosion and it went boom,"

WTF? lol

^+1
Also, nice props OP. Over all, very cleanly executed

[/youtube]I'm going to have to put one of these jokes on it soon and have some fun

Thanks warhead :wink: No, I really don't plan on modeling it after anything. Though I do expect it to look a bit like a 60's sci-fi gun once completed :D For a kid who moves in between Countries It's funny that you should mention that. In general, it seems as if the kids I meet in the states have mo...

I just took a look at the guys channel. mind=blown. You guys should have look.

Apologies for the long delay in-between updates, I got distracted: http://i1191.photobucket.com/albums/z461/guy123456789/small%20plane_zps04b7bac9.jpg :roll: I recently got the ignition system working 100% I had also gotten the new and improved ejection mech working but of course, minutes before mak...

That doesn't sound right because they have different areas... Forgot about that little tidbit, lol :D But yea you were right. Though the needle movement would be minimal because water pressure still is pressing against the bourdon tube... unless you used a really wide syringe. Also, what "little pi...

why not connect the gauge to the nozzle end of a syringe, and cut down the plunger so that just enough is left to keep the seal steady? That way as you go down the pressure increase will compress the plunger, increasing the reading on the gauge. unless that gauge was sealed, and the hardware store ...

but if an Australian can get the parts anything is possible to newbies. Aussies here would know our struggle, crap laws. If it´s simple for you to get that co2 bottle refilled, then it´s better than Portugal. Don´t know why you Australians always make yourselfs such a martyr, you have ebay .au, bun...

Yes, otherwise, just buy a blowgun.
What caliber do you plan on using?

Assuming you don't have access to machining facilities, I'm all for idea 2. It would work a lot better though, if the insert had a fairly large diameter compared to the inside of your barrel, with a hole approximately the diameter of the barrel through it. Unlike the picture were the hole is almost ...

Not bad at all for only for 4 bar.
I'm sorry but It appears as if I have forgoten to mention how fckn amazing this thing is so far. So here it is.

But seriously, very nice work. I wish I had bread board skills like that!
