Well done Andrew with this gadget - once again you've managed to put together a really impressive gadget that is useful in improving power utilization and control of the heater operation. But putting the thermostat controller in the ambient temperature zone, the feedback between the environment and heating element is improved considerably, giving more comfort and control to the user. Impressive!
I agree with you that it is surprising that manufacturers did not think of this. It's such an inexpensive solution to a problem that should have been noticed.
You know what would be cool? Imagine an option where a ZigBee enabled the thermostat to be mounted across the room -- anywhere in the room so that we get to enjoy a more average temperature from the heater. Yeah, that's not as simple and elegant, but it might be an add on.
Given the heat around the country this summer, winter can't come too soon. I never thought I'd say that. This thermostat is a great idea. You identified a real need, Andrew. The thermostats on space heaters are useless.
Andrew, thank you for coming up with this design. In our case, mountain winters can be especially cold in a sort-of-insulated cabin on stilts, so our thermostat problems are keeping the space heater downstairs on for a longer time at a given heat output.
I know it's out of season right now, but winter will get here before you know it. I built three of these thermostats last December and they served me quite well. I have received numerous requests from friends and family to build some units for them. They are great for a hobbyist, but they are too labor-intensive to build and sell without printed circuit boards. They're otherwise pretty cheap to make. I used the shells of the three remote controls I hacked up to make two volume controls (GF #192) and a fan control (GF #198). Now, I'll have to buy enclosures and outlets for the power units of any more thermostats I might make. The remote control enclosures were perfect for the job. You can probably buy a remote control at a flea market or a garage sale that has lost its transmitter or doesn't work. Or you could just build one of my remote control gadgets and use the shell from the hacked remote.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
