Origami

Today at work our larger Human Resources team had a social activity, which was learning some Origami. When I was searching Amazon for paper, this wood grain pattern pack was suggested and I didn’t hesitate.

From making paper airplanes I remember how hard it is to get proper half folds at the corners, and it was no different here. You also have no idea how something is going to turn out until the end. I love making things, so this was fun. I decided to challenge myself even more by keeping up to make two of each model.

I have a lot of the paper, so when I need to chill out from work, I’m going to try some of the other models. If you’d like to give it a try, check out the Origami Fun site, which has a lot of instructions.

Wood Storage and Organization

My wood storage got out of control. Something had to change.

First I wanted to build a lumber rack on the opposite wall of the room. I remembered watching John Heisz make a simple one on YouTube, so I followed what he did almost exactly. I already had plywood strips the correct width, so I chopped ten to 30″ long. Then I whipped up a simple tapering jig on the bandsaw to make quick work of cutting 20 arms out of old wood.

I ran the arms through the planer and rounded them on my router table. I also rounded the plywood edges because they were rough. After a lot of repetitive gluing and screwing, the pieces were assembled.

I drilled holes and preloaded all 60 screws to make it easier to put them on the wall.

I stacked two at every other stud and loaded it up!

It’s so nice to see what I have and be able to easily access everything. I didn’t expect it to be so full already though!

Next, I wanted a rolling lumber cart for sheet goods, off-cuts, and scraps. Doing a Google image search was a bit overwhelming, but I found inspiration from several styles:

I drew up some ideas. Since I already had the lumber rack on the wall, I kept reminding myself I didn’t need space to store long boards. Originally I was set on incorporating an old drawer in my design (first picture below), but it was too limiting. Some of my design choices were dictated by only wanting to use materials I already had.

Instead of doing a final plan in SketchUp I decided to wing it, giving myself flexibility through the build. I took full advantage too by changing several things along the way.

I had bought The Auto-Jig from Armor Tool a week before, which I’ve had my eye on for quite some time. It’s worth every penny and saved a ton of time.

One morning I built the base and cut most of the plywood pieces. Then I assembled almost all of the complicated half before attaching it to the base. On day two, the second side was much easier to assemble. I used the router along with some sanding to round the sharp edges. I slapped some castors on to make it mobile. The last task was making the drawers, which I put together with a nail gun and glue.

Finally it was time to load up the cart and organize everything. Big surprise, it ended up very full!

Sorting through all of the wood was a good opportunity to purge and I ended up with a big pile for the trash.

I can actually use the room again!

Reclaimed Wood

A few weeks ago I picked up this truckload of old wood someone was giving away.

I pulled a lot of nails, cleaned up the wood, and cut it down to size. Turned out to be a nice stack, though I’m not sure what I’ll use it for yet. The right projects will speak to me at some point.

Making a Bluetooth Speaker

It’s been too long since I posted about designing a speaker in SketchUp, but other projects moved up on my priority list between then and now. Well, over the last few days I finally made the speaker. In the end, the delay was worth it, because several of the steps were a lot easier with tools I’ve acquired over the last few months.

Other than the design, the first step was to get a board. I ordered the INSMA TDA7492P Chip 25W+25W Wireless Bluetooth 4.0 Audio Receiver Digital Amplifier Board on Amazon after watching 2 otherbuilds with the same board. To make sure it was going to work, I hooked up my speakers for a quick test. I salvaged the speakers out of on old set of computer speakers I had in college.

I ordered a couple of different button styles from AliExpress, so I tried both types out, ultimately deciding to use the larger buttons which also had a blue LED ring. The smaller buttons were nice but not right for this project.

I did those tests around the same time I was designing the speaker. Several months passed before I touched any of the components again. Since I wanted to use my own buttons, switch, and LEDs I needed to figure out the best ways to connect in to various points on the board. This involved a lot of poking and prodding with a multimeter. I figured everything out and did all of the soldering and wiring prep work to help with assembly once the box was built.

I had taken some general measurements when iterating on the design, but I thought it would be a good idea to create a cardboard model before cutting any wood. This mockup of the walls was an inch too short, but it let me get an idea of what kind of space would be on the inside. Knowing that the 1/2″ plywood would use up a lot more area, I increased several dimensions and changed the angles on the 3 front pieces.

After cutting the 3 front pieces and two sides, I measured and marked all of the spots where I needed to drill holes.

Then I spent a lot of time with the drill press. There was a lot of measuring and calculating because pretty much everything going on the front face needed some kind of recess.

It was looking pretty good!

Since I hadn’t updated my SketchUp plans for the changes, it was tricky getting the correct sizes for the top, bottom, and back pieces. I ended up screwing some parts together in a step-by-step process and then making small cuts on the new pieces to inch up on the fits. At the end I had to do a bunch of sanding on the front face, which was the last piece I screwed together. It was really cool seeing the design come to life.

Time for some finishing work. I sanded edges and cleaned off all of the dust before I did a quick coat of spray paint. I wanted to try a neat technique I’d seen, so I did a bunch of sanding to rough up the paint. Then I coated everything with 2 coats of stain/poly, while doing a light sanding in between. After the first coat of stain, I unscrewed everything to apply the final coat because I wanted to make sure nothing was stuck together on the joints.

After letting everything dry it was time to work on the guts. I used the time-lapse recording option on my YI 4K Action Camera for the first time, which worked well, so here it is with voice-over to explain what I’m doing during the assembly process.

I wanted to give it a coat of Minwax paste finishing wax when I was done, but with all of the buttons and speakers in the way it would have been too hard to work around them. Should have done it before. I’m pretty thrilled with how the paint and stain combo turned out.

The dimensions ending up being 5″ tall, 10″ wide, 4.5″ deep at the sides, and 5.75″ deep in the middle. It weighs just under 4 pounds with most of that coming from the 2 speakers. It’s hard to get a sense for the size in the cropped images above, so for scale here is a comparison with a beer bottle.

I’ve been using an old Jawbone Jambox for music in my garage gym. This is so much more convenient because it plugs in and has a permanent spot. No more worrying about a dead battery or trying to find the Jambox when it’s time for a workout.

Whenever I was using the Airdyne or Ski Erg, it was hard to hear the Jambox. Judging by the test below, I should be able to crank the tunes now. I played 30 seconds of “Welcome to the Jungle” with both speakers, starting at the 1:00 mark, and increasing the volume every 5 seconds.

RBT 1911 Pull Back

I’ve always wanted a rubberband gun, so when I saw awesome kits by Rubberband Tech at Maker Faire Detroit I had to get one. I could have a sweet gun and build it myself. The 1911 immediately got my attention because of the slide action and the functional clip. The hardwood version (I picked zebrawood) of the kit was an extra $10 to make it $30 and a big bag of extra rubberbands was $5.

The build, spread over several days, took about 7 or 8 hours, which was much longer and harder than expected. A lot of difficulties were from the instructions being short on details. They tell you to sand several pieces but don’t get into how much sanding is required (A lot and then a lot more!), especially to get the trigger mechanism working properly.

I tried to video the entire process, ending up with over 140 GB of footage! On a first pass through iMovie at 20x fast forward the video was way too long, so I exported and ran it back through at 8x more. At the end of the video is a demo at normal speed showing the gun in action.

The stain I used on the zebrawood pieces was called Espresso and the one I used on the rest of the gun was an English Chestnut. I finished it off with 2 coats of a finishing wax. As mentioned in the video, I’m not happy with the end result of the staining. I wish I had done a second coat of the espresso stain on the hardwood pieces, or gotten a little lighter stain for the rest of the gun, or even both.

Now I need to make some targets. I have some ideas involving electronics for timing and scoring.
