Baking Better Bread With Steam

It’s not often we see a build that turns you into a better cook without any electronics whatsoever. [Chris]’s method of baking better bread with steam is one of those builds, and we’re more than willing to test it out on our own.

If you’ve ever tried to bake bread at home, you’ll quickly notice the crust is much thicker and harder than a loaf available at a bakery. The thickness of the crust can be controlled, however, with a careful application of steam. To make a better crust, [Chris] used a pressure cooker fitted with a valve to inject steam into an oven through his oven’s exhaust. Not only does this gelatinate the starches in the bread crust, but it keeps this gelatin from hardening too quickly.

The end result is a thin, golden brown crust that makes for the perfect loaf of bread. Of course, the proper application of steam does take a little bit of practice. If someone is up to the task of Arduinofying this hack with a few solenoid valves, PID sensors, and a high-temperature humidity sensor, send it in and we’ll put it up.

Bang-banging Your Way To A Perfect Cake

bang-bang-oven-control

[Rob Spanton’s] house is equipped with a rather cheap oven, which was discovered while his roommate tried using it to bake part of a wedding cake. If someone took a shower during the baking process, a large portion of unit’s gas pressure was diverted to the boiler, causing the oven to shut off completely. This is obviously not a good situation for baking cakes, so the housemates decided to construct a makeshift controller to keep temperatures in line.

They started by installing a pulley on the oven’s knob, which is connected to a small motor via a long rubber belt. The other end of the belt connects to a small motor, which is controlled by a Pololu 18v7 motor controller. A K-type thermocouple monitors the oven’s temp, feeding the data through a MAX6675 converter to (presumably) [Rob’s] computer.

Since they were in a bit of a time crunch, [Rob] and his roommate [Johannes] decided the best way to keep the oven at a steady temperature was via bang-bang control. While you might imagine that cranking the gas knob between its minimum and maximum settings repeatedly wouldn’t be the ideal way to go about things, their solution worked pretty well. The cake came out perfectly, and the maximum temperature swing throughout the entire baking process was only 11.5°C – which is pretty reasonable considering the setup.

Hacking Cakes With LEDs, The Sequel!

A few weeks back we ran a piece about the convergence of making and baking in an attempt to create a cake festooned with working LEDs. The moral was that not every creative idea ends in victory, but we applauded the spirit it takes to post one’s goofs for the whole internet to see and to learn from.

[Craig]’s LED matrix proved unreliable…and the underlying cake didn’t fare much better, resembling that charred lump in the toaster oven in Time Bandits. The cakes-with-lights meme might have died right there if not for a fluke of association…
