Improve your watercooling radiators cooling efficiency by more than 20% per fan with these optimized fan shrouds and air flow optimizer. The model prints easily on almost every 3D printer and is designed to be printable without support. If you want to buy it printed and shipped to you, leave a comment and we'll see how we can deal.

After starting the schematic and PCB design during last sunday's stream, I could put a little more time into this during the week. Let's have a look at the cleaned up schematic and try to replicate the bench test from it to verify the schematic this time. This pre-charge module is basically a live saver in any offgrid DC/DC converter or DC/AC inverter (or other high capacitance load that allows heavy inrush currents) and high capacity battery bank setup, no matter if you use a diyBMS, Batrium, REC-BMS that use an external DC contactor or a Seplos, JBD/Overkill/Daly/JK-BMS or any other that uses MOSFETs for load/charge switching. For the test today we will add an emergency-stop button and an input capacitance mock, to see some real world behavior of the circuit. ## Timestamps: 00:00:00 - Intro 00:06:34 - Prep the SOP/SOIC Adapter Boards 01:12:59 - Setup the Comparator Module 02:22:15 - Setup the Driver Module 03:27:10 - Final bench testing of it all 04:03:05 - Outro **As always, if you like this kind of stuff and want to get more, please don't forget to: follow, repost, share and like!** ## Donations The research, buying and development of all this hardware & creating content takes **considerable amounts of money, time and energy to produce, render and publish**, so that you can enjoy this without annoying advertisements.

## Building a new Voron 2.4 CoreXY 3D printer Next to our venerable 3D printer it was finally time to bootstrap the brain and muscle of the new CoreXY based Voron 2.4 R2 printer, to give us more options and abilities in future projects. We will have a livestream each Sunday while we are printing more parts and assemble the new printer. **As always, if you like this kind of stuff and want to get more, please dont forget to follow, repost, share and like!** ## Donations Research, buying all this hardware & creating content takes **considerable time and energy to produce, render and publish**.
