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 »

Custom Wood Phone Charging Cradle

After getting a new phone recently due to a volume switch that was out of place, and my inability to solder well, I had a problem. Actually, I’d had the problem for a while with my last phone, but I couldn’t seem to get it to plug in correctly, and when I finally did, it was facing away from me. What I needed was some sort of cradle that I could put it in, sort of like what’s seen in the illustration above.

I could shop online for a cradle for my phone, but I really didn’t. Instead I designed and build one myself out of wood as seen in the video below. That’s always easier, right?

Perhaps it’s not easier, but it was a fun project, and one that wouldn’t be too hard to make, even without a CNC router. I made the device in three layers, which you can see in the video laid out in Draftsight. The yellow represents the middle piece of wood, and the red and white layers sandwich the micro USB connector inside (The DXF drawing file is available here if you’d like to make your own).
