Why have we stopped using ATX computer power supplies? I explain what the pros and cons are of going with an simple “industrial” power supply vs. a full ATX supply, including being able to shut it down through the firmware yet still getting a solid 5V supply for a Raspberry Pi!
The Elegoo Mars is a nice resin 3D printer – but is resin 3D printing nice? 🤷♂️ This is not a cheap 3D printer. It’s a very affordable 3D printer – but unlike filament-based printers, the story doesn’t end there. So while the Elegoo Mars is an incredible, high-detail resin printer, you can’t just it to any other machine that costs under 300 bucks. So today, we’ll look at whether Elegoo are actually managing to democratize printing or if you should just stick to FDM.
Let’s 3D print… with metals! There are a ton of options available now for producing 3D metal parts, but the most straightforward one involves laser-welding pulverized stainless steel directly into your final shape. No de-bindering, post-sintering or other steps necessary to get a fully functional part. And One Click Metal is working on making that technology a lot more affordable*!
This is my digital dashboard that I just made – it sits on the wall right next to my desk and is just “always there”. I’ve got the local time, world time, well, I mean go by US west coast time, I’ve got the weather, my upcoming video plan and to-do on here and in the last two weeks that I’ve been using it, it has already made my work so much more efficient because it totally keeps me on track.
We’ve already looked at how to mechanically build a digital dashboard based on DAKboard or MagicMirror², but simply installing the software or opening up a browser window on the Raspberry Pi isn’t going to be a great solution in the long run. Here’s the software setup and the modifications that I added to the regular Raspbian install to make it a smooth experience!
Today, I’ll take an absolutely boring part and make it interesting – shelf brackets. Using topology optimization with the free version of Autodesk Fusion360. If you want to have a computer automatically come up with the best geometry for a part that for example will support a given weight, yet use as little material as possible, there are basically two different automated design processes that have become pretty popular these days.
