A new tool for DIY folks - a "Voltage Switch"

I have developed a cool little "voltage switch" board that can select one of two circuits based on whether an input voltage is higher than a reference voltage. If the input voltage is lower than the reference voltage, circuit one is enabled; if it is higher, circuit two is enabled.

This is going to prove to be extremely useful for DIY folks. You can use it to turn anything you want on or off based on the signal from any sensor. :nice:

These are going to be building blocks for my water injection project: I will use one for the MAF sensor and one for the ACT sensor. When the input voltages from both sensors are higher than their respective reference voltages, the water pump will be turned on.

I'll probably use another one to monitor the water level and turn on a LED when it is getting low.

I'd be willing to make them for people at cost plus a few dollars for the time it takes to put the PC board together. If anyone is interested, PM me.
