Howto Video: Poster Stand – With Magnets!

I needed an easy way to display posters at the Orlando Maker Faire this year. I could have purchased something, but being a Maker Faire I decided to actually make a couple of poster stands. The feet fit nicely into the body, and I even drill it out at the end of the video to hang on the wall for storage/display. The coolest part though is that it uses magnets embedded in the MDF/wood to hold the enlarged 12 x 16 photo.

Arduino Strain Relief Enclosure

Here’s an interesting idea, a project box, or enclosure for an Arduino Uno that not only keeps the board in place, but secures the wires as well. I actually did most of the build a month or so ago as an experiment, and didn’t think I’d use it in a video, but eventually decided to (wow, great story bro). Check the build/results below, or you can see more details on instructables if you so prefer.

Router Flycutting and Reinforcement Bolt Upgrades

As usual, I was having a bit of a problem. When we last left my CNC router, it was able to cut soft materials, but these cuts weren’t entirely uniform from one end to another. To remedy this, I used a technique called flycutting, which mills the entire table with the router itself. The idea here is that by doing this, you’re aligning the table to exactly how the router cuts.

In theory this should work quite well, but as you can see here there’s something else going on, the table has separated from its base. Perhaps warping could be expected given it’s location in a humid garage, but I had actually helped this along by cutting several slots in the material in order to attach a set of clamping rails.

To remedy this, I installed another set of screws in the middle of the table. Perhaps they should have been there to begin with, but my modifications weren’t doing it any favors either. In theory, I could have drilled into the MDF inline with the bottom and top bolts, but I hadn’t taken the table off yet, and wasn’t sure what was under there.

Once the MDF table was off, Read more »
