Convert Magnetic Stirrer To USB-C
prusaprinters
<p>I picked up this compact magnetic stirrer on amazon. By no means am I advocating this specific model for anything other than being inexpensive and small. I noticed power was a barrel plug that used 5v 1a for power. This is what USB offers by default. Decided to mod this to accept a usb-c cable for power, and took a bit more time to add spots to store the stirrers when not in use. </p><p>What is needed (amazon links offer rev share to me, I appreciate your support):</p><ul><li>This Specific <a href="https://amzn.to/3eNMNel ">Magnetic Stirrer</a></li><li><a href="https://amzn.to/3CZktO9 ">5v USB-C breakout board</a> There seem to be similar variants as well</li><li>4x m3 6mm or 8mm bolts and nuts</li><li><a href="https://www.amazon.com/Soldering-Portable-Adjustable-Temperature-Programmable/dp/B0B9S9TLS6?crid=27S6POD9UCL7Z&keywords=ts80p&qid=1666434069&qu=eyJxc2MiOiIzLjY4IiwicXNhIjoiMy4zMSIsInFzcCI6IjMuMDYifQ%3D%3D&s=industrial&sprefix=ts80p%2Cindustrial%2C128&sr=1-5&ufe=app_do%3Aamzn1.fos.18ed3cb5-28d5-4975-8bc7-93deae8f9840&linkCode=sl1&tag=gltovar0e-20&linkId=ad09e493047581b0f6c35e4e3ca5192c&language=en_US&ref_=as_li_ss_tl">Soldering Iron</a><br> </li></ul><p>Nice to have, multimeter.
