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.

Solar heater update
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.
DIY heat exchange system
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.
Squishy Circuits Workshop
Tog will be hosting a Squishy Circuits workshop on Saturday 2nd of July, taught by Tríona O’Connell.
Squishy circuits are a great way to demonstrate electrical circuits to kids (and adults!). It consists of a conductive dough and an insulating dough that are used in the building of circuits, along with batteries and more usual electrical components like motors and LEDs.
During the workshop, we will make some batches of both types of dough, and afterwards we’ll see some useful demos you can use to teach with it, and also have some hands-on fun building circuits.
Making the dough will involve lots of flour, so don’t wear your favourite black outfit, but apart from that there shouldn’t be too much of a mess. There’ll be demonstrations of how you can use the dough to investigate resistance in a circuit.
And the fun part, building sculptures that incorporate electrics, or building giant squishy circuit boards. You can bring your imagination and build whatever you fancy. Tríona will be on hand to offer help or suggestions as needed.
This workshop is free to attend although registration is required, as space is limited. It will last about 2 hours, starting at 2:00pm. You can use the form below to register.
— The workshop is full! You can still sign up to be added to the waiting list, we’ll notify you if a space frees up (this also lets us know if there is interest in organising another similar event) —
What to bring? Bring a 9V battery. Optionally, if you’re already familiar with Arduinos you can bring your own (this is optional and there’ll be plenty to do without one!).
Hackathon Pallet bucket seat
This weekend we worked on a few project
This chair is made from a pallet, some foam & red velvet, check out insctructable for how we made it.
Working on a heat exchange for roof, it works off 350 cans painted black mounted on roof of TOG and then heat is pumped back into space. Will keep you up to date when we get further on with project main need is to fill up frame then take out bottom and top of cans.

Lessons learned:
One very important thing I learned when building this and drilling such small holes cool your bit as much as possible otherwise you will end up spending a lot on bits that you do not want to.
