In this video, I build a DC electronic load that’s controlled by a raspberry pi. Purpose A DC Load is useful for testing lots of different things. If you have a power supply and want to make sure it’s able to deliver its fully designed potential, then you can use a DC Load to test …

New 3D Printing Channel and Website
Now that I’m doing more and more 3D printing projects, I decided to create a separate channel and website to host the 3D printing projects, and keep this website primarily focused on my electronics projects. The new youtube channel is smbaker-3d-prints. On this channel, I do the occasional filament review, print some models and try …
Read MoreHot Shoe to 1/4-20 Quick Release Magnetic Mount for LumeCube
Short diversion from the usual electronics posts, while I talk about my new camera light… I designed and 3D printed this magnetic quick release mount to attach a LumeCube v2 that I recently purchased to my DSLR camera. Purpose I noticed recently that my camera lighting is sometimes lousy, the Polaroid light that I had …
Read MoreBuilding a Power-over-Ethernet (PoE) Power supply using a DPS5005 module
In this video, I design an build a PoE-powered lab power supply. Purpose What can I say, I like building power supplies. 🙂 Seriously though, I’ve been looking for a reason to play with these DPS5005 and related modules ever since seeing them on popular forums and video blogs. The DPS5005 is relatively well regarded, …
Read MoreScott’s FrankenNUC: 10Gbe Fiber Network on a 5th Generation Intel NUC 5i7RYH
In this post, I modify my 5th generation NUC to support 10Gbe fiber networking: Purpose A popular trend in homelabs is power efficiency. While some people are still buying every power-hungry used R710 they can find on eBay, others are going the opposite route, trying to maximize performance per watt. In my opinion, there’s no …
Read MoreRAIN: Redundant Arrays of (In)expensive NUCs
Break from the usual electronics project posts and time to discuss some server management. I’ve always had a server. Even in 1986 I had a server. We called it a “BBS” back then, but it was still a server. Throughout the years, the server has evolved, from Lantastic ARCNET to 10base2 coaxial Ethernet, to Gigabit …
Read MoreDIY Wireless Temp/Humid/Pressure sensors with Raspberry Pi Receiver, for monitoring stored 3D printer Filament
In this post, I made some wireless sensors, using BME280 temperature, humidity, and pressure sensors, together with SYN115 transmitter modules. I used these to verify the storage of vacuum sealed “PrintDry” 3D filament storage containers. Purpose I bought some PrintDry vacuum sealed containers on Amazon. These are high-end containers, costing about $20 each. Yes, that …
Read MoreRaspberry Pi 4: Do you need a fan? What’s the best fan for a raspberry pi 4?
In this video I spend some time thinking about the temperature of the new raspberry pi 4, and whether it needs a fan. Idle Temperature I installed rpi-monitor and also watched the cpu temperature using console tools. In the case that I used, I found the pi 4 at idle to be running at about …
