DIYer 3D Prints and Wires a Programmable Home Thermostat

These days, we’re more inclined to ask, “Is there anything that can’t be 3D printed?” than we are to exclaim in astonishment at the latest 3D printing feat. From 3D printed implants that help human bodies grow new cartilage (and, coming soon, internal organs and skin)…

and 3D printed rocket boosters to 3D printed cars and buildings, the additive manufacturing industry is booming to say the least.

Falling within the “more modest achievements category” but still worthy of mention and admiration from the DIY crowd is this project from an Imgur poster known only as “KK4TEE.” This seemingly incredible maker, who also seems quite tech savvy, recently bought an old house that was lacking a working thermostat. Rather than buying a thermostat, KK4TEE decided to make one himself.

“The DHT22 gave me some problems. At one point the thermometer would only output -20’C, but humidity worked fine. I ended up taking it apart and probing around with a multi-meter. After a few minutes of fiddling it started working again, but I lost my trust in it.”

Just to give you an idea of how much money he saved, we did some searching on Home Depot’s website and found that a wi-fi thermostat for your home can cost you anywhere between about $100 and $300. A programmable home thermostat will range in price from $20 to $280 (although we’d be reluctant to trust the cheap one with our heating and cooling bills). … (Read more)
