HOW TO MAKE A HOT TUB HEATER ?

Question by    |  last reply


Desperatly seeking low temperature or power failure alarm for hot-tub. Any ideas on DIY or hacked comercial product?

I have a serious need for a sensor that either detects when my hot-tub temperature drops below a certain point, or when the electricity supplied to my hot tub is disconnected. A wireless remote alarm would be the best, but wired would also work. I found this need when the power to my hot tub failed and some of its plumbing froze. I am willing to use any microprocessor or even modify an existing device to fit my needs. The commercial versions are a little pricy for my budget. Any help would be greatly appreciated.  Is this a great place or what?

Laptop water cooler? Answered

Hello I have a laptop that gets hot while gaming and i don't have the money for a desktop right now. Basically my idea is to lay down 4 fans then i lay down a mesh sheet then a coil of copper pipe then a another mesh sheet then my laptop  The coils would go to a tub of slightly chilled water and be pumped though How well would this work, Is it possible? Portability is not an issue as i would have this mounted to a piece of wood by my desk Thanks, Kaden

Looking for a 12V solution to prevent another 12V circuit to power on -- Reverse relay

Hello, I have 2 separate 12 volt lighting systems in the yard.  One is a low-voltage garden lighting that illuminates paths, trees, and a hot tub shelter. The other is a security lighting system, a 12V system that lights 6 each 900 lumen flood lights powered by solar panels and batteries. Other than shine a flood light from the landscape light system at the security system light sensor, is there a relay I can install that prevents the security lights from powering on until the landscape lights turn off?  I guess I am thinking of the redneck version of the relay that puts generators into play when the power goes out. I want my yard to be friendly while the landscaping lights are on, but we dont need a soccer pitch until the guests go home. Kind of like a rock concert.
