I’m an active 3D printer user. I have been for the last 9 years. I started with Anet A8. Boy oh boy, printers back in the day were problematic. I’ve probably tinkered a second printer out of it.  Then I moved on to using Eneder and Prusa MK3. I also used a few resin printers. I had a hog of a printer….

Airports closed, metros stopped mid-tunnel, and-most importantly for the local butchers and ice-cream shops-fridges and freezers went dark. It’s the kind of event that makes you realize just how much we all rely…

Why Are We Even Talking About This?The growing demand for electrical energy (EE) is a more significant problem than one might think. The world is not like SimCity 3000; building new infrastructure is extremely challenging….

As energy grids evolve to accommodate growing demand and renewable energy integration, Virtual Power Plants (VPPs) are emerging as an innovative solution to enhance grid stability and efficiency. Central to the success of VPPs is the incorporation of smart home technologies, which transform individual households into active participants in energy management. By leveraging distributed energy resources (DERs) and intelligent devices, smart homes…

If you’re interested in how we powered up our 3d printer when Zombies are running through the earth, check Part 1 of this article. Ok, so we’re prepared for our setup but haven’t we stated that in our scenario resources are thin world is inhabited by but not most pleasant brain eaters? YUP.

Evolution of 3d printers made them as much of a tool as chisel or saw, they’ve stopped being a gimmick or something geeky and became fully fledged tool for every shop.

DSP-700GB is an affordable alternative to new, fancy power supplies that would cost around 100 EUR for same current rating. Which is staggering 56A at 12VDC. As it will not just output 12V on its pads, it needs some additional treatment. Connect pad 4 and 7 to GND (left or right doesn’t matter), that will make it “Always on”, it will always…
