4 years ago Awesome. Did some rummaging/ruminating – would something like this be useful for simplifying things? Should be plug in and go.
USB->12V (up to 1.5A ish) converter on a single board with micro USB connector and header for FAN. TBH – I don’t know the exact connector used for chassis fans and what the pinouts are, but that’s easy enough to change.
Parts cost should be under $20 and I can assemble limited quantities at zero cost, where quantities is a number between 1 and 50. Any more than that and I’d probably throw it to an offshore manufacturer.
If it’s not obvious, the board is intended (designed is too strong a word) to sit inside the case and then the USB socket is accessible from the outside.
I haven’t really thought about dimensions/shape, but also easily enough sorted.
Oh, Nokia 3310 for reference 😉
Phil.

4 years ago Ah ok that looks interesting. For this version I’m trying to keep the components to things people can buy over-the-counter or online from local (Aus) suppliers. Definitely interested in another version that’s a bit more advanced for people who want additional features. This could be incorporated into that.
The fans use a 4 pin connector but I’m not sure what the actual name of it is, should be easy enough to find it on digikey or similar
Cheers,
Adam

4 years ago Cool. I'll make a couple up for my own purposes. Apart from the PCBs, I source the components from local suppliers when I do my own assembly. Purely for hobby purposes, I sell a few electronic bits on Tindie. Their fees and PayPal fees are a pain, but not aware of too many alternatives.
Got an old board with the same basic layout handy, so I'll test that. Found a local shop that has a twin pack of the Corsair fan and ordered those. The 3D printer yielded fruit overnight, so now on to getting the filter and putting it all together.

4 years ago love it! Keen to see how the build goes with that board.

4 years ago nice one. If you have a model of the board you can flick me I’ll make a version of the fan housing that has a place to mount it, unless you’re already doing that?

4 years ago awesome, thanks
There's just an extraneous character at the end of the link to the Jaycar 12V usb booster cable in the README. Got the 3D printer humming away...
