| == What are we doing? == | | == What are we doing? == |
| There are currently two proposals for a Maker Faire project. The airship is currently the most likely.
| | We will be running the hack area, where everyone can sit and tinker/hack. We shall have to take tools & equipment for people to use. |
|
| |
|
| * An airship
| | ===Some members will individually be presenting=== |
| * A 3D printer (documented below)
| | If you want to be involved, ask! |
|
| |
|
| ==Proposal for a 3D printer Maker Faire exhibit==
| | * The Battenberg (An autonomous Airship) - Russ/Jonty |
| | | * A steam-powered turing machine - Srimech |
| ===Concept===
| |
| | |
| A giant 3d printer, using concrete, plaster or some such substance for media. Takes the whole show (or maybe a whole day) to print a gnome, tux, pedobear, statue of Jonty etc.
| |
| | |
| * How about liquid/expanding foam for the media? It's light, sets quickly, comes with a print-head (nozzle, flow control, and cartridge system), and can be broken up quite easily. However, the fire-retardant stuff that I used was quite toxic - but perhaps there is a friendlier version? --[[User:Teabot|Teabot]] 09:16, 14 September 2010 (UTC) | |
| ** Nice idea. I'm sure I came across some recently that I thought would be handy if I needed a lot - very cheap, or bulk, or DIY or something. | |
| | |
| ===Design===
| |
| | |
| Based around a scaffolding tower (could be hired in Newcastle rather than transported) with a winch at each corner suspending the hopper / dispensing nozzle in a frame of 4 wires (could use 3 but 4 allows travel right into the corners).
| |
| | |
| Winch drum rotations and cable tension are measured for position feedback and load sharing. Winches could be windscreen wiper motors, wheelchair motors or similar.
| |
| | |
| Prints a layer, then parks the hopper. Hopper is flushed while layer is allowed to set. This could allow a reasonably rapid-setting cement without fear of blocking the hopper (parking place should be accessible in case it needs manual attention).
| |
| | |
| ===Development===
| |
| | |
| Make a mockup the size of a fridge. Possibly using the glass fridge if it's truly broken. Might also be usable in hackspace as a vending machine if fitted with a grab. Use this to develop coordinate transformation and failure mode testing. Use it as actual exhibit if larger version is not finished in time.
| |
| | |
| ===Bonus features===
| |
| | |
| *Camera on hopper for hopper's-eye-view. Use camera for 'instrument-landing' if it ends up being manually controlled.
| |
| *Replace hopper with ball for destruction of object.
| |
| *Make a subtractive printer by starting with a large block of foam and removing bits with a suspended strimmer.
| |
| | |
| ===Questions===
| |
| | |
| *Can we use reprap software with a coordinate converter ?
| |
| *What media to use ?
| |
| *What's the budget ?
| |
Maker Faire UK 2011 is on the 12th and 13th of March 2011, in Newcastle. Several people from London Hackspace and other Hackspaces will be attending.
