A Wireless Wood Stove Monitor

[Michel] has a wood stove in his basement for extra heat in the winter. While this is a nice secondary heat source, he has creosote buildup in the chimney to worry about. [Michel] knows that by carefully monitoring the temperature of the gases in the chimney, he can hit the sweet spot where his fire burns hot enough to keep the creosote under control and cool enough that it doesn’t burn down the house. To that end, he built a wireless wood stove monitor.

The first version he built involved an annoying 20 foot run between the basement and living room. Also, the thermocouple was mounted on the surface and made poor contact with the chimney. Wood Stove Monitor 2.0 uses a probe thermometer on an Exhaust Gas Temperature (EGT) thermocouple to measure the temperatures. The intel is fed to a thermocouple amplifier to provide a cold-compensation reference. This is shielded so that radiant heat from the stove doesn’t compromise the readings. An nRF24L01+ in the basement monitoring station communicates with another module sitting in the living room display so [Michel] can easily find out what’s going on downstairs. When it’s all said and done, this monitor will be part of a bigger project to monitor power all over the house.

This Little Piggy Stayed Home and Became a Stove

FPQRAZDHRWN9J10.MEDIUM

This little piggy probably should have gone to the market. Instead, its become an extremely decorative, and cute, wood burning stove!

After being inspired by a similar Instructable that guides you through the creation of a wood stove using an expired gas cylinder, [Ruudvande] had to try it himself. The problem was — he didn’t have a gas tank. Luckily for him, he found someone who did, but as it turned out, they wanted to turn it into a barbecue! So, slightly sidetracked, he built them a barbecue using the center of the cylinder, and got to keep the ends and enough steel to make Mr. Piggy himself.

Almost the entire wood burning stove is made of scrap bits and pieces of steel, and various pieces of mounting hardware. Armed with just a MIG welder, [Ruudvande] welded it together all by hand, and we think it turned out great! He’s not quite happy with it yet though and plans to upgrade the chimney, put a larger grill inside, paint it, and even add a glass window to the door.
