USB cable Version with a visible cable running from the base to the tracker, its less work but there is always a slight chance of ripping out the cable if you get stuck at something.</p><p>2.) Pogo Pin version, involves more work but results in a cleaner build with no external cable.</p><p>For the Pogo pin version you need a 1,5mm² copper wire as a contact point so the spring loaded pins of your Vive tracker can make contact to it. Bend the wire in a very narrow U shape and push it through the holes, you maybe need to drill the holes with a 1,5mm drill bit to make it pass through smoothly, take a key file and file down the u bend to have a flat contact surface. (see pictures)</p><p>What you need:</p><p>Soldering equipment, thin wire. isolation tape, super glue.1,5mm²coper wire.</p><p>Lipo Charging board with protection:</p><p><a href="https://de.aliexpress.com/item/4001046570639.html">https://de.aliexpress.com/item/4001046570639.html</a></p><p>Voltage step up converter: ( SET VOLTAGE TO 5 VOLTS or your going to fry your tracker!!)<br><a href="https://de.aliexpress.com/item/1005002849228099.html">https://de.aliexpress.com/item/1005002849228099.html</a></p><p>Battery: Any lipo battery not exceeding 32x62x8mm<br>There are two "Base" versions one for a slightly smaller 1750mAH lipo battery and slightly bigger one with 1800mAH. you can always go for a smaller one that fits into the cavity.</p><p>M4 brass thread inserts:</p><p><a href="https://de.aliexpress.com/item/33008141694.html">https://de.aliexpress.com/item/33008141694.html</a></p><p>Heat sink (not a must but a nice to have add on) for the charging board:</p><p><a href="https://de.aliexpress.com/item/32838291524.html">https://de.aliexpress.com/item/32838291524.html</a></p><p>To mount the Tracker on the Everlast base you need 3 pieces of the S07 screws you can find in the following link:<br>(Thanks to user AnnabellaRenee for the tip)</p><p><a href="https://de.aliexpress.com/item/33026272553.html?spm=a2g0s.9042311.0.0.6a334c4dU34ntk">https://de.aliexpress.com/item/33026272553.html?spm=a2g0s.9042311.0.0.6a334c4dU34ntk</a></p><p>3x angled usb C cables: ( not needed if you go for the Pogo pin approach)</p><p><a href="https://www.amazon.de/gp/product/B07DBW9YLK/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1&amp;tag=thingiverse09-20">https://www.amazon.de/gp/product/B07DBW9YLK/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1</a></p><p>4x M4x6 screw</p><figure class="media"><oembed url="https://www.youtube.com/watch?v=pg8YeqJirTs"></oembed></figure><p>&nbsp;</p><figure class="media"><oembed url="https://www.youtube.com/watch?v=jBhSXiRCNRk"></oembed></figure><p>&nbsp;</p><p>&nbsp;</p>
