The Dublin Hackerspace
Working on some plexy glass today taking the plexy and putting on side of bench you are able to heat up the side of it and then press down on it with piece of wood. This is shown in images below. What I did was took a piece of red plexy bigger than A4 and then measuring in few cm on each side bending over making sides. Then to fill in back and bottom just cut piece of see threw plexy and glued with super glue.
Site is at present under construction we are in process of moving servers!
After going to Makerfair UK with a few people we got a chance to create these long long long exposure cameras made from Beer can and some photo paper Read more here
Sun photoed every day for 6 months and playing a little with the levels. Just put photo paper in a beer can and put a pin in it leave up for a few months and scan in photo.
Mame cabinet is working well, got to put in 6 buttons and make up new face plate for it. But had our first few games today and worked quite well.
Controler board for buttons
Wiring up of buttons and controls.
Following the social on 2nd July, we now have enough cans to fill our
solar heater. We cut the top and bottom from each can. A regular can opener
removes the top very neatly. We remove the bottoms with a hole saw.
We built the frame from a sheet of plywood, and laid some 25mm
polystyrene sheets into the frame as insulation. We now arrange the cans
in parallel columns and paint them black to absorb the sun better. The
top and bottom of each “can column” is arranged into a common manifold. We
glaze the completed unit with glass or plastic.
We blow air from our building in the bottom and take warmed air out the
top back to the building. We use a small electric fan to do this.
Thanks to all that came to social last week we are almost there with the DIY heat exchange system we are going to put on roof and start to heat the space.
Will be trying to finish off this weekend at Hackathon if anyone is about drop in and bring a project.
