I've read a lot about the two different methods over the years and I've always had my own opinions about the subject but now I actually have two different lasers with two different red dot methods I feel like I can publically add something to the discussion based on my own experience. The red dot on a laser cutter is a single point of light that shines down onto the work piece to show you were the laser cutter is going to cut. It makes it a lot easier to line up scraps of material with where the laser intends to perform a cut. Because the laser head is cone shaped you can technically predict where the laser will be and some of the really cheap K40 lasers do away with the red dot entirely, but I think it's always worth paying a little bit more money to have it included. There are two distinct methods for putting a red dot on the work piece, the first involves fixing a small laser diode to the cutting head to shine directly down onto the material. Most of the

In the near future I'm going to be doing a few more cyberpunk events so while it's probably a neon dystopia these things all share the same issues. Techno gadgets need to glow/flash/move or other things for a whole weekend in a place where access to electricity may be limited and changing batteries round all the time can be a pain. I've recently picked up several of these USB powerbanks from Poundland  (worth noting that they are £2). The teardown review was relatively positive so I thought it was worth a try. The first blinky LED project I've got running on it has currently been going for 48 hours non stop so I've made the decision to build one of these into the project rather than AA batteries (project details in due course). It's always worth designing with low power in mind and there are a whole bunch of tricks you can do to reduce the power consumption but I'm looking forward to getting these into projects.

My friend Ed was making these pancake pawns on his 3D printer for sale on Etsy  (not available currently). They're cute and he's got a wide range of them now so I wondered if I couldn't make something similar on the laser cutter which would be faster to produce. The laser cut version were definitely faster and had the option of adding colour but they're a little bit large and I never got round to shrinking them down to see how small they could go (The new laser would probably excel at the details though). It's another one of those projects that would go a lot further if I was actually interested in D&D myself :)
