I have had this cheap 12V switching power supply that (claims) to be able to deliver 30 amps. It is a common power supply type, and are commonly used in consumer applications, especially in the LED lighting industry. In fact, the exact same model can be found mounted on my Creality Ender 3 3D printer. Background Personally, I find these power supplies perfect for many use cases, especially when one considers their pricepoint.

The lightbox has been finished! I designed the acrylic and manufactured it on our laser engraver/cutter. The end result was better than expected, although I had to condense (shorten) the acrylic overall to meet the max acrylic dimensions of 70 square cm. After the transparent acrylic was finished, I screwed it into the lightbox and “force fit” everything together as designed. Luckily my tolerances and dimensions matched perfectly. The acrylic had to be custom designed to fit the screw holes and the box geometry.

Paper bags are great. They are much more sustainable than their plastic counterparts and they are reusable and recyclable. I often keep or collect these bags because they have so many uses. The issue I have is that I don’t have a good place to put them. At the moment, they are stored behind my recycling bin, being propped up. When I take out the recycling they all fall down and make a mess.

With my new HAM radio license in the books, I bought the Baofeng UV5R as my first HT. Between its low-cost and various features, I think its been a great radio to start out with. With an upgraded antenna (almost not optional) and a larger battery bank, I’ve found the radio to be a pretty solid unit. Unfortunately, there is no direct way to plug in the radio’s speaker and mic jacks to a computer soundcard to transmit and receive sounds to and from my PC, but with a simple cable modification, this can be done.

I got my HAM Radio License! I am now a registered HAM radio operator as KC1VTJ Hope to hear you on the air, 73
