Remixed from this enclosure: https://www.thingiverse.com/thing:1857562
This remix was made for a different 8.9" LCD harvested from a small Lenovo laptop from 2005. The HDMI controller board was this one from eBay. https://www.ebay.com/itm/154575099919
Most parts for this build are spares, and I do not recommend buying a 7A/hr RC battery specifically for this screen, which is why I made the size of the assembly longer and deeper. The connectors for this battery are EC5 and JST 2.54mm 5-pin.
However, some other spare parts include: two speaker diaphragms from a 2016 turn table one Hiletgo 14.8V Battery Management System one spare power switch one 10A fuse one 10A schottky diode one silent $5 fan from nowhere one 6" HDMI cable two buck converters adjusted to 12V and 5V respectively one boost converter adjusted to 19v one charging buck converter adjusted to 16.8V two DC 5.5mm male barrel jacks one DC 5.5mm female barrel jack
I decided to get a hold of a broken Lenovo Yoga with a Core i5, 10th Gen, but this is subject to change depending on what kind of I/O I can find in a different board like the LattePanda Sigma.
This build is meant to be an absolute unit that eats the Steam Deck for breakfast. Like anyone else during COVID, no matter how late in that arc, I need to get my bang for buck too. It might be somewhat more expensive in the short-term, but I am sure it will last longer than an official product and be easier to repair.
