Re: HVAC Missing 'C' wire

Many thermostst cables are stapled inside finished walls and ceilings so it is not always a simple task to pull.one out and another in. The cost of this device is quickly exceeded by wire and the labor expense. If you DYI the circuit, the cost Is much less. Nope, I make nothing from the sale of thes...

Re: How select the Commonly Used Electronic Components

What I think is most confusing for most is the sea of capacitor types and the best pick for the application. All types have specific attributes but I have not seen a lot of data on specific applications. The vendor's filters help to separate them but picking the right type is a different problem. Ma...

I just tried to attach a drawing as a PDF and it was rejected.

HVAC Missing 'C' wire

I was recently faced with installing a programmable HVAC thermostat, but the new thermostat need the 'C' (common) wire and that was not in the existing cable. I searched and found a gadget called Add-A-Wire that adds 1 extra wire to either a 4 or 5 wire existing thermostat cable. It's about $25 and ...

Here's the best idea I have ever tried and no, it's not my idea. It's been kicking around some CNC forums lately...

Re: Experimenting with Hot Glue..

Wire Wrap Stuff

I just uncovered an old stash of wire wrap tools; A hand operated wrap gun, and bits, a hand wrapper, un-wrapper and maybe more.
Since posting pictures here seems to be a problem, if you're interested just PM me and I'll send a snap.
Swap,trade,buy...whatever works!
