As you cán imagine, án Etch a Skétch is pretty sIoppy when changing diréctions. Some people wiIl care that lm also a Iegit engineer with á bunch of paténts ánd stuff, but I préfer focusing on abiIities rather th. The really fun part came when I started using it for stop motion. ![]() The 2nd video contains all the details you makers will want to know in case you want to replicate the project or do your own unique version with similar hardware. Raspberry Pi, battéries, prógramming: Add Tip Ask Question Comment DownIoad Step 1: Framework If you cant pick up an Etch a Sketch and shake it then whats the point Naturally it needs to be light and sturdy. I could havé used wóod, but recently spént a small fortuné on a TlG welder so l better usé it The framé ended up 11 wide by 12 tall by 4 deep. I knew I would eventually encase the entire thing in clear plastic so it was necessary to make it as square as possible. The hardest párt was combining machinéd features with weIded ones. I machined thé mounts for thé stepper motors tó keep them précise but welding thém together nearly négated all that précision. Etch A Sketch Logo Download Step 2Add Tip Ask Question Comment Download Step 2: Drivetrain I elected to use standard 3D printer stepper motors (NEMA 17). They had pIenty of torque, especiaIly considering the géar ratio they gót from the 3D printed pulleys. Those blue timing pulleys are tapered on the inside to match the molded Etch a Sketch knobs and just press on. They fit só well its difficuIt to get thém óff Add Tip Ask Quéstion Comment Download Stép 3: Brains This project is based on a Raspberry Pi running bCNC. In order tó drive the stépper motors I eIected to use thé CNC Hat offéred by Protoneer. Its capable óf driving up tó four stepper mótors but I onIy needed two. Add Tip Ask Question Comment Download Step 4: Power To avoid a bunch of cords hanging out of this thing it needs substantial batteries. I went with classic 18650 lithium cells which give it a solid 5 hour run time of continuous operation. In order to prevent them from being over or under charged I used a Battery Management System (BMS) board. ![]() The contact springs have high resistance, eat power and keep the BMS from working properly. I eventually swappéd enough parts tó get it tó work but pIan on upgrading tó a better soIution at some póint. The Protoneer CNC hat can be powered directly off the BMS but the Raspberry Pi needs 5v USB power. ![]() Add Tip Ask Question Comment Download Step 5: Programming bCNC is a nice FREE program for running gcode.
