We discovered the cheap Amazon sketch panels as a flat light source for our mobile rigs years ago. But it required a USB cable and you had to basically blind everyone in a 500 foot circle when using the darn things. But they were kinda cheap and durable and better than T-shirts. After we designed the DragonLIGHT as a permanent flat light generator we figured that those LED sketchers could be hacked to use our light to dim it. But also allowed full ASCOM Alpaca integration and remote control. COOL! This little 3D printed bracket can be made in sets and screwed to the wall to hold those panel for an Obsy installation.
