Make: Projects – Water Bath Thermostat

Make: Projects – Water Bath Thermostat

This project was inspired by “Cooking for Geeks” author Jeff Potter’s quick DIY sous-vide hack. My plan, initially, was to just hack the controller into an enclosure with an A/C outlet, the idea being that you could just plug any heater you wanted into the outlet. Looking around for cheap temperature controllers, however, I happened across the STC-1000 on eBay for $25. It’s not PID, but it has proven to be plenty accurate enough for almost any practical purpose. And since the STC-1000 has both heating and cooling functions built-in, the logical next step seemed to be to split a single A/C outlet so that you could plug a heater or a cooler (or both) into it and use it for all kinds of stuff.

How-To: PVC and Cable Dyeing

So many projects we feature use this boring white pipe because of its low price, widespread availability, and versatility. Since PVC doesn’t take paint very well, this PVC dyeing technique is perfect for adding those crucial finishing touches […]

The Flame Tube Project (and Contest Coming Soon!)

The Flame Tube Project (and Contest Coming Soon!)

Based on the work of German quantum physics pioneer, Heinrich Rubens, I designed this flame tube so propane gas inside the tube flows through holes drilled along the top, and flames are then lit above. I send a sound wave into the tube with a loudspeaker at the other end. When the tube is driven at one of its resonance frequencies, flames form a visual standing wave pattern, as you can see in the picture. Vary the pitch and change the volume to get different patters.
