Vlog 75: T-962C reflow oven conversion to Reflow Master Pro 

Yes, I have one of those and it totally cures the fume problem. In my old lab the exhaust duct went up through the ceiling and was vented outside, and I haven't got it set up yet in the new location.

Good tip. I have 2 powder extinguishers and a CO2 extinguisher, which is the one I held up in the video. I got that one specifically to keep near my laser cutter so I wouldn't destroy the optics if I had to put out a fire.

@@SuperHouseTV Ah yeah, of course it is CO2 with that wide nozzle

Plenty of relays (literally hundreds) but I wanted an SSR so there'd be a chance to do some modulation of the fan. It doesn't really work well with 50Hz AC though. The zero-crossings don't occur often enough.

@@SuperHouseTV Nice Nice. What is the model of that SSR? Also what's the Size of that plastic housing case? That's a nice size there.

Yah, mechanical relays are not the thing you want to use for PWM based control - They cant really switch fast enough, and so they'll wear over time and go bad and then you might be left with an always ON relay when it dies. That's really risky :(

@@UnexpectedMaker Yes, especially the tiny little 5V relays, though with 12V you can at least use semi decent relays, or at least ones that have real 10A rated contacts, as the 230VAC fans anyway do not respond well to PWM to do speed control, and using ones with actual electronics inside will just result in them being cooked to well charred in a few operate cycles. Also beware of cheap SSR devices, many claim a lot of power handling, but inside all you get is a cheap 8A triac and optocoupler, with possibly an input current circuit that might be more than a resistor and a diode.

I forgot to include him!

Must be one, though I doubt you want rosin flavoured pizza.

I was diagnosed with Crohn's disease a few years ago, which hasn't been great! But most of the reason that I haven't recorded a proper video for so long is that I find the process of making and editing a video to be really painful. It takes many days of work to create a 20 minute video, and life has been too busy in recent years to block off that much time for it. I've just been trying to get by, without adding more things to my To Do list.

@@SuperHouseTV I don't blame you. I do everything from software engineering to plumbing to automated grow systems. I tried to video to share my knowledge and realized it unfortunately takes 5-10 times more effort than doing the project.
