Toaster reflow oven controller. Abandoned project due to some bugs and safety.
##Usage
Put boards with solder paste in the oven. Press the red button. When the led switches off you can take the boards out or something.
##About
Schematic is in KiCad. Schematic idea is from ST app note "MICROCONTROLLER AND TRIACS ON THE 110/240V MAINS". Reflow profile.
Uses weird temperature sensor. Heats boards to 150 degrees (1.3 kΩ, 3.143V, 41200), keeps there for 1m 10s and heats it up to 220 degrees (1.8 kΩ, 2.75V, 36000) 1m 30s.

Questions
How big is the ToastFlow PCB?
It measures 40 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ToastFlow use?
23 parts, built around the ATTINY13A-SU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ToastFlow KiCad files?
From the jaanuskalde/ToastFlow repository on GitHub, at the commit this page was made from: the board is schem/toastflow.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ToastFlow design in my own project?
Its repository states no licence, so its author keeps all rights: ask jaanuskalde before reusing the design.
