I've been intrigued by DROP1410's mod seen on this post:
Click here to see it. I'd decided to give it a go and see how it went. Originally I wanted a switch to be on the project box itself, but it wasn't viable and didn't really make sense.
In DROP1410's post he'd used (see diagram below):
- 2k resistor
- 3'9k resistor
- 470k potentiometer
- LTC1799 variable pitch PCB
I, however, didn't have an LTC1799 lying around, so i used a Variable Clock v2 from Thursday Customs.
I ended up using:
- 500k potentiometer
- Variable Clock v2 (with 10k resistor hand-soldered on the high limiter) For some reason, the pre-soldered SMD resistor wasn't working.
- Standard Mini-B cable
- Mini-b female SMT connector
Here's my end sketch:
I had a fair bit of trouble finding the mini-b socket. For some reason, Jaycar electronics didn't stock them, and they're the only store remotely like radioshack that we have in Aus (from what i know anyways). So i searched everywhere for something that i could de-solder one from.
I found these two digital keychain photo frames which were $4.95 each - they even came with mini-b cables!
I wired it up as seen in the drawing - using a small project box as a housing - and then used a drill and a dremel to cut the hole on the front faceplate.
It was the first time ever using a dremel and I definitely have to work on it. (Any advice / easier ways to have cut a hole would be awesome)
I used hot glue to stick the SMT connector in place and used heat-shrink on all my cabling (the circuit kept shorting out).
I placed the switch in the top right corner (see pic) and had to re-locate the capacitor that was on the PCB. I attached two wires and then moved the cap to somewhere it wouldn't be in the way.
Here's the end product! There's a video rendering at the moment which i'll post soon!
Let me know what you think!
Its got an integrated overload protection circuit to protect my laptop from power hungry DMG mods hahaha
