Rechargeable TrackIR clip

thingiverse

I've been using a pretty bad DIY trackIR clip for a while now, from before I had a 3d printer. So, I decided to upgrade. This is a 3d printable TrackIR clip, which uses a 3.7V 1200mAh 103040 lipo battery, TP4056 board for charging, and 3 SFH485P IR LEDs. It attaches to my headset with 6mmx5mm neodymium magnets and washers, so that I can easily put it on and remove it. I've included .stl for printing and .f3d files if you want to edit parts to fit other batteries or charge boards. There is a BOM in the files section. Note that this was designed for the Steelseries Arctis 7 headset, and may not work well, especially on open back headsets. "headset magnet" part attaches to the headset with double sided tape, with either magnets or washers inserted into them, the "magnet clip" part holds the 6x5mm magnets and has holes for the posts on the headset magnet part to go into. It also has screw holes so that it can attach to the trackIR clip part with nuts. These two are completely optional and only necessary if you want that quick disconnect feature. Otherwise you can just double side tape the trackIR clip part directly to the headset. The trackIR clip part holds all electronics, and the lid part covers it, with a hole for the TP4056 board's LED to shine through. The lid is also optional (though do make sure the battery is secured in place if you decide to omit it). The circuit has two LEDs in series with each other, and another LED in parallel to those two. This reduces current draw significantly (reduces by 1/3 compared to 3 in parallel), but consequently those two LEDs in series change brightness more with voltage changes. This is pretty much a non issue until you get to really low battery levels.
