Hey
As some of you may or may not know, im gonna monkey around and make my own fan controller box, with speed controller. Current methods at the moment involve lots of hacking wires, soldering, using a PC power supply and i think its all pretty messy. Heres my idea https://www.thctalk.com/cannabis-foru...ad.php?t=14462
But since i need something in the meantime and im a stoner and not finished project yet, I've had to whip something up in the meantime and I'd thought i'd share.
So here goes.
You will need........ (most of stuff can be found at maplins)
- A pc fan with connectors intact (make a note of amps of all fans used)
- 2 x 4 pin molex to 3 pin fan convertor/connector (1 per fan, depending on the type you buy. In my example 1 per fan you used) If only using one fan, you'll still need another molex connector to finish the job (or you'll have to solder). This can be found easily from an old psu,
- A 12v power adaptor (please take note of the Amp output)
- Electrical Tape, Wire cutters/strippers
Things to note....
Add up the amps, usually .10 or .25 on fans. If they are greater than the Amp output on your adapter. You need less fans, or an adapter with a higher amp output.
Step 1:
Cut the top off the power adaptor. Leave some wire on the end of the bit you've cut off, You might want to use it later. I intend to in my fan controllers next incarnation.
Snip the wire in the middle and pull the ends apart (if you have a twinned cable, IE both in seperate lil plastic covered tubes)
Strip about 5-8mm of the plastic cover from end of wires and twist so no bits of wire are sticking out.
Step 2:
Get your molex connector and find the holes with the wires going into the 4 pin connector
Place your two wires OUTSIDE the holes. not in them as the connectors wont connect together. Ensuring no bits of copper are loose or touching each other.
Insert the 2nd molex connector into it to secure wires in place. Please be careful the wires dont move or you dont strip the cable cover. You maye wish to use a flat screwdriver as a wedge so it can pass over the cables.
Alternatively, if you have a crimping set, you can crimp the power adaptor into a molex pin. Can be found at maplins too.
Or you can solder onto the pins direct. but that sucks in my honest opinion and i cant be arsed.
how ever you connect it, tidy and cover with electrical tape.
Step 3:
Plug in your fan/fans to the 3 pin fan connectors.
Then plug power adaptor into the mains. WARNING - Dont be a moron. Plug it into a power socket DIRECTY, with a switch on it. And have the power switch to off before you plug it in.
Switch on and hopefully ta da
Writting the damn thread n taking pics took longer than making this gizmo. lol
Hope this helps.
