I’ll drop the oven off this weekend (or shoot me a note when you know you will be at the Space)
I also have some welders blanket (woven fiberglass) that you can use to insulate it…
I think the thermal cutout was 100 C (it’s in the area on the right side of the oven behind the controls, not the oven chamber) and I got it at Lees…
I may have another one , I’ll take a look…
I do need help with the mechanical stuff ( internal insulation, adding IR reflective tape to the glass door, building a door opening mechanism, replacing the wire tray with an aluminum sheet, etc. ). @packetbob has nice pictures of his oven build. I think he did a great job.
Yeah I can put a couple hours in helping with this.
Might have an idea for insulation. experimenting with VHT paint for my 3d printer. If it works would be good inside the oven. Its a silica embedded paint so might help reflect some heat back in. Will be curing my thermal block tonight see if it does anything to make it better after that.
Also I have experience with thermisters so can help with putting a couple of those in for heat monitoring.
I met Phang from Rocketscream in Shenzhen. Totally awesome guy. He is sending me a pcb, I think for http://www.rocketscream.com/shop/ospid-kit perhaps I could donate it as the basis for this build?
I have lots of welder blanket left over from my build (It’s woven fiberglass) so send me the dimensions and I’ll cut up what you need. I found that the edges were a bit of a pain so I “edged” them with Kapton tape to keep it from unraveling…
I will dig up the picture I took during the build and get them online somewhere…
That reflow controller is really interesting. Since it’s open hardware it’s nice that they uploaded a full schematic, makes me tempted to lay it out on a PCB and fab it myself. It’s probably worth the $56 CAD (incl. shipping) though, it’d likely cost just as much if I made it. If Tom gets the sample then we can definitely source the chips and solder it ourselves. Though you’d have to figure out how to attach the shield to the MSP or find an Arduino somewhere.
Without that shield you still have to put together an equivalent circuit. Were you thinking of doing it all on a protoboard instead?
