DIY Vapour Phase Frying Pan Project
intabits:
For the "poor man's version", inclined (by necessity) to mess about with some mechanicals, maybe the hotplates from one of these could be used with any metal dish of suitable characteristics? I imagine there would be a lot more choice in dishes when the electric heater requirement is eliminated. (Maybe with a heat spreader plate/heatsink between hotplate and dish)
(sorry, quick nighttime photo)
I've found a few of these by the side of the road for free.
Or similar hotplates might be had from and old electric stove...

Anything is possible I guess. Explore possibilities and see what happens. A glass lid is handy. You might find a suitable frying pan for lot a lot. The hardest thing is the cooling. You might be able to repurpose a desk fan

Hi, great information. Really appreciate the work you have put in to this and making it open source. I have some Galden HS230 and have been looking for a starting point to get a system up and running.
Is there any python code available yet for experimenting with?
Thanks
Trev

SHi, Sorry that i went quiet on everyone. I've had been sucked into a project that did'tn let me breath, but escaped on Friday. :-) Many of you will know what that is like. But they paid well.
So, an update. I have pcbs, and all the parts to do a build. I'm actually going to use the Frying pan to build the frying pan controller boards. I've got a hacky hack hack controller set up and while its ugly, it does actually work. The SSR's and other bits have arrived from Aliexpress, they all came on free or nearly free shipping so it does take some time.
I'm going to set up my system on a DIN rail, and house it all in a polycarb box. Theres mains ( 240VAC ) in this project, you need to show the appropriate amount of care. I know we all sometimes go.. Sigh Another Warning but it has to be said. If your not confident with working with the mains, find someone who is to help you through it. I will be setting up my controller with both an RCD and and internal circuit breaker.
Software wise, the project will use Python to control / measure everything. I'm going to use the PyMCP2221A driver. So far i've been able to communicate with the Driver and set the GPIO bits. I did attempt to do some I2C stuff, but it did'tn work at the first attempt and I had run out of time.
Python from a pc is just one of many options.. The I2C bus is exposed on a header, so if you wanted you could connect a microprocessor, or you could use a raspberry PI.. Eventually i think i'll probalby use a Rpi, and stick it in the box, and then network connect it.

That's not a good idea at all. Almost guaranteed to be counterfeit with triac rated <50% of current written on SSR and dodgy insulation.
