It’s 2024, and there’s no getting around it. Grid energy is expensive. [Darrell] realized that a lot of his money was going on water heating, and he came up with …read more Continue reading Hot Water Heater Hacked To Run On Solar Juice
If you’re lucky enough to have central heating and/or air conditioning, with an automatic thermostat, you probably don’t have to worry too much about the outside temperature. But central HVAC …read more Continue reading Baseboard Heaters Get Automated
Rocket stoves are an interesting, if often overlooked, method for cooking or for generating heat. Designed to use biomass that might otherwise be wasted, such as wood, twigs, or other …read more Continue reading Rocket Stove Efficiently Heats Water
If you were reading this post a month ago, you could have been forgiven for thinking it was an April Fools post. But we assure you, this is no joke. …read more Continue reading Home Heating With Bitcoin Miners is Now a Real Thing
Much like vinyl records, tube amplifiers are still prized for their perceived sound qualities, even though both technologies have been largely replaced otherwise. The major drawback to designing around vacuum …read more Continue reading Tube Amplifier Uses Low Voltage, Sips Battery
While we might all be quick to grab a microcontroller and an appropriate sensor to solve some problem, gather data about a system, or control another piece of technology, there …read more Continue reading MOSFET Heater Is Its Own Thermostat
Like the incandescent bulb before it, the compact fluorescent (CFL) bulb is rapidly fading into obscurity as there are fewer and fewer reasons to use them over their LED successors. …read more Continue reading New Possibilities from Fading Lighting Technology
There’s a fine line between simple feature creep and going over the top when it comes to project design. It’s hard to say exactly where that line is, but we’re …read more Continue reading Filament Dry Box Design Goes Way Over the Top
At Hackaday’s Minnesota office, we appreciate central heat and hot coffee because the outdoor temperature is sub-zero in Celsius and Fahrenheit. Not everyone here has such amenities, and families living …read more Continue reading $7 Tent Heater Provides Comfort on a Budget
It’s not too hard to make your electronics project get warm. Design your traces too small, accidentally short the battery inputs together, maybe reverse the voltage going to your MCU. …read more Continue reading Using a PCB to Reflow PCBs – Take 2!
