== Proposal 3: Two-Stage Light Gas Gun, Dave S ==
== Proposal 3 by [[User:Eagleapex|Eagleapex]] ==
A 2-stage light gas gun uses light gas (usually hydrogen or helium) compressed rapidly to create tremendous pressures and temperatures, firing projectiles at incredible speeds. Because the light gases have higher speed of sound than ambient air, and the intense heat from compression raises the speed of sound substantially more, it is possible to fire projectiles at faster than the ambient speed of sound (something that is basically impossible with a traditional gas gun). Ultimately it would rock to make a device that was cocked by hand like a crossbow and which fired a projectile (ideally a standard Airsoft pellet or BB) at multiple times the speed of sound.
I have a crude and somewhat unfinished simulator I put together for this purpose that should be able to at least help direct the design.
The general design is as follows:
* Surgical tubing resistance bands are used to store the energy
* A heavy mass is propelled down a linear rail by the resistance bands
* The heavy mass strikes a piston, compressing the working fluid (hydrogen, helium, or air)
* A thin metal scored burst disk ruptures under the pressure, expelling the projectile at very high speeds
Some parts that could benefit from the use of a machine shop, but which do not require it:
* Burst disks of varying thicknesses, with carefully scored "X" to control the rupture
* The piston (probably UHMW turned into a conical shape)
* The "forcing cone" with a taper matching the piston
* Various parts such as the trigger mechanism (use a simple design like on old siege engines), linear rail, etc
Parts / materials:
* Pump tube: any metal tubing at least a few inches long, with a smooth round inside between perhaps 0.5" and 2" ID (I can probably provide if necessary). Will need to be closed on one end, requiring either threads, flanges to be bolted, or welding
* Piston: UHMW (I have tons)
* Linear slide: 4 ball bearings should be enough to make a really nice slide
* Surgical tubing: I have enough to get us started
* Barrel: I can contribute a BB gun barrel and BBs
* Mass: large bars or pieces of steel, lead, water in a soda bottle, sand, whatever we can get, and the more dense the better
* Burst disks: we can do without these if we are anxious to fire it and don't care much about performance. I can provide steel, copper, or aluminum shim stock if nothing else is available
* Trigger mechanism: something simple like on an old siege engine. This can be omitted and it can be fired like a bow, but that will limit the control
Tools:
For turning the piston, forcing cone, and possibly some other parts a lathe is required. If one is not available I can machine the parts at home beforehand, but a larger/heavier lathe would be great if possible. A drill press will come in handy. Some parts of the trigger could be made with a laser cutter or a CNC router/mill of some kind.
Scope / Alternatives:
Depending on what tools are available, we have a lot of options. If a lathe is unavailable I can do any turning at home beforehand. If anyone can provide ball bearings, that will make a nice linear slide for the driving mass, otherwise we can just make UHMW or acetal bushings. If no machine tools are available at all, we can use the laser cutter to make some plastic parts (brackets, bushings, etc) or if we're really short on time and resources we can just make a ballistic pendulum suitable for measuring the velocity of supersonic BBs and do the gun another time.
I can CAD up any parts once we have chosen the scope. This would be an awesome project because it would be the first device of its kind documented in the hobby world, and would make for a great article. I have already started on a quick and dirty smaller-scale working mockup, which can be used as a reference.

Latest revision as of 18:00, 6 April 2012

We are excited to announce a very hacking winter-time Hive76 open-house hosted by NextFabStudio: Hive76 Open House December 20th, 2011, 7pm - Midnight @ NextFab Studio @ 3711 Market Street This Hack-tacular event will be at NextFabStudio and will get us free access for the night to some of their most awesome tools, such as: CNC plasma, CNC embroidery, e-textiles, electronics, 3D printers, shop bots... There will be food too. So Awesome. I'm proposing the first project below (we can have many of them!!)... Add your proposal below. Be as descriptive as possible so NextFabbers will be able to assess feasibility and logistics given the time constraints. Let's get hacking! -Jordan

Proposal 1: 2 Complete Hive76 Chess Sets, proposed by Jordan

A double-set of Hive76 chess pieces and boards. I want 2 complete sets in 4 colors so we can play Bughouse Chess which is just begging for 4 3D printed chess set pieces. If we get really creative maybe some magnetics and electronics could be enabled as well. Here's complete details, and an attached inspirational rendering. =] The most awesomest chess set on Thingiverse is the gangsta chess set:

Thingiverse Gangsta Chess
The original gangsta chess set on Thingiverse

I've compiled all the pieces onto one build plate and printed on reprap -- it is a 4 hour print. I'll make a set in Red, Orange, Yellow, Blue. The chess pieces have a 1" or 0.8" diameter circle on the bottom. Maybe we'd want to print the pieces larger, too, given the access to NextFab Studio's higher-end 3D printers. The complete STL files are here. Here's a rendering and the completed set:

At NextFab we could lasercut an entire chess board made of interlocking pieces in these 4 colors, then glue them together. It will take some testing to get the kerf just right and figure out what size to make the tile so the pieces fit comfortably well inside. It would also be nice to laser engrave the chess boards. Maybe make the chess boards all Black acrylic with surface etched white squares. Not sure yet. At NextFab I'd also like it if we could embroider some felt with the Hive Logo and then cut out and glue the embroidered felt onto each individual piece. This will also take some testing. To comment or make suggestions please join our maling list!

Proposal 2: Assorted Hive76 Labels, compiled by Dave S

  • Laser-cut name tags for all members
    • Cut/etched plastic or etched anodized aluminum
    • Perhaps suitable for labeling members' storage bins?
  • Laser-cut rubber stamps with Hive logos
  • Hive76 "maker's mark" CNC-machined steel punches, perhaps in a couple of sizes
    • Good for permanently labeling soft metals, plastics, leather, etc, with a quick hammer strike

Proposal 4: Laser or CNC cut Hive76 Hard Plastic or Wood Business cards. Chris Terrell

If I could make this image smaller or even figure out how to delete its source I would. I Am weak Noob Sauce :( As a newcomer to the Hive 76 scene I have noticed a void in public appearance. A fun Project could be getting together and designing a simple card with whoever is interested. Burn in anything from QR codes and drawings to the basic general information.
