planned improvement: increased number of slats, single line for each slot- the width of plasma kerf.

The human powered internet cafe looks at the issues of renewable power generation and aims to educate users to the energy requirements of surfing the internet.

Users are asked to peddle the exercise bikes in order to turn a dynamo which would in turn power the computers. If users fail to peddle hard enough the computer monitors will begin to flicker encouraging them to peddle harder.

The thing would ideally be placed in public areas where all forms of society could view it and try it out for them selves, thus educating as many people as possible.

For my wedding in October 2011 I asked my fiance if I could build something, she only asked that it not be tacky. This is what I came up with. It's a modular folding photo booth. I designed the model in Sketchup, programmed it in Autoit, and gave it a nice Glados voice. I needed an input device and I decided to make a serial comm button. I took a 555 timer and made it generate a 4.8kHz square wave. At 9600 baud this translates to UUUUUUUU plus one garbage character when the button is released. for now it only uses a Webcam to take photos but hopefully I will be find a deal on a canon power shot sometime in the next months to upgrade it. Since the printouts are resized, the small webcam resolution isn't noticable, however it won't be suitable if i wanted to incorporate the singles frames into a album. I'm working on some upgrades using the twitter api so I can have the booth update me whenever it is taking photos. This way I can tell it's status and share photos easier.


Here is a video of it's assembly and the software.

I built this CNC router from designs I saw all ver the place and like the idea of using aluminium channel and steel. I simply built the table then measured the gantry to suit. You can build any size this way as long as you re-enforce properly. The control board came from HobbyCNC and the motors are NEMA 23. The power supply I built (simple 24v 7A).

This Machine is an an experimental prototype created for the purpose making light weight hollow castings from rapid setting resins cast into rubber molds.
-Centrifugal force allows liquids to flow evenly to all interior surfaces of an mold and cures to an solid state while in motion within minutes.
- ideally the motion of rotation could be optimized toward the shape of an object and the speed of an curing material so that the casting would have even wall thickness no greater than necessary to support the structure of the shape.
_This process would also lend it self well to casting waxes into rubber molds to produce patterns in an lost wax process for metal casting in an foundry situation.

Solid Works Drawings of a Mendel that is all metal, uses linear bearings on all axis and dual belts on X and Y to cope with extra weights involved.

This printer was started as a result of my friends astonishment of what i was able to make using a cordless drill and a hacksaw. my repstrap didn't sit flat or square it wobbled, i used lead screws to drive all the axis' as a result it was slow best speed i could get was 1000rpm ~650mm/min, but at that speed the frame wobbled and the resulting prints had waves in 6 different directions :P

This is a bracket for a small angle grinder. It can be mounted around the shaft and has holes for 608zz bearings for connection.
The bracket was mounted between two scantlings which are connected to a board.

I added two fixation brackets at both sides of the blade with holes for M8 bars.
In combination with a ruler starting at the blade it is very easy to cut the bars for a 3D printer.

This is a lotus or rose or what ever is most Awesome. I made this as a gift for someone so I went the extra mile and made some brass leafs colored green and Copper wire stems so oxidize them in a brown green tone. I went to TIG the copper to the stainless stalk but It was too small so I just brazed it. I ended up Threading the stem to use a 4/40 nylon acorn nut below the flower and a 4/40 acorn nut at the top to look real.

This is a thing describing how to make timing pulleys for an Ultimaker style printer. It describes how to combine inexpensive polycarbonate plastic MXL timing pulleys with aluminum spacers to make a robust timing pulley for an Ultimaker style printer with 8mm outer shafts.
