Standing Desk Converter
Posted: February 17, 2014 Filed under: Build, Hardware Leave a commentI’ve been thinking a lot about health lately, thanks to Clairvoyant’s health challenge. And I’ve been reading about the health benefits of a standing desk (or maybe not).
You can buy standing desk converters like these:
- Ergotron Worksurface for WorkFit-S
- Workez Standing Desk Adjustable Sit Stand Desk
- Ergo-Stand – Convert Desk to Stand Up Desk
But they start at $75 & they don’t look great, so I decided to build one. I prototyped it with stacks of books and came up with a 12″ rise for my keyboard and a 20″ rise for my laptop on its mStand. The mStand isn’t required, but I use it when I’m sitting so it might as well stay. 18″ wide is enough to hold a keyboard and trackpad comfortably.
I built it out of some 3/4″ cherry ply I had leftover from the desk. I routed the edges so they’re rounded and I put a brace at the top of the back to hold everything square.
If I were to build it again, I would change some things:
- move the legs in about 3/4″
- have shelves overhang the riser by about 3/4″
- blend the roundover more carefully into the lower shelf
- use a wider brace so it’s more certainly square
But that stuff is minor. I’m pretty pleased with it.
Where’s the Map?

Some time ago, Google released an update to their Maps API that broke recpath.com.
Since the site is no longer functional, I’ve discontinued it.
Can you put it back?
I do not have any plan to do that, but if you’re a programmer, contact me and I’ll send you the source code. It’s GPL-licensed and you could take over development.
What am I going to use now?
Maybe you’ll like one of these:

- Map My Ride (http://www.mapmyride.com/)
- Gmap Pedometer (http://www.gmap-pedometer.com/)
What’s powerfulmojo.com?
It’s my personal blog where I document stuff I did or things I think are worth looking at.
You could see how to build a desk, a USB Easy Button, or a lamp out of plumbing parts.
Leather Headphone Wrap
Posted: February 5, 2014 Filed under: Build Leave a commentI’m still happy I tried out 3-D printing by making a headphone wrap, but the device itself leaves a little to be desired.
A perfect headphone wrap would be:
- Small shirt pocket size at the biggest
- Easy to wrap or I’ll never use it
- Easy to unwrap or I’ll curse at it
- Secure it needs to hold the headphones while preventing tangles
My 3-D printed model scores a 3/4. Unwrapping is a pain, so I started looking for alternatives. Instructables user amalkhan has this model, which I like a lot. I also saw a few others that were more like a headphone wallet.
So I’m going to make one out of some scrap leather I have that matches my satchel. It comes down to 6 steps:
1. Make the Pattern
I picked a size that seemed reasonable and cut it out of cardboard to make sure it seemed right. I traced the cardboard on the leather. I want it to be 2 layers like the bag.
2. Cut the Leather
This is where I realized that two layers really complicates things:
- The inner layer has to be shorter
- The stitches have to be radial; not all parallel through the leather
- Once you glue it up, it will never really lay flat for you again.
Still, I want the extra weight of 2 layers.
3. Glue and Trim
Put glue on one end of the leather and keep it secure. It’s best to wait until it’s all set before you continue. I did not do that. Once it’s secure, clamp it around a dowel or something and glue it the rest of the way.
After it’s all glued up, trim off any over-hanging leather corners to even up the edges.
4. Stitch
Another reason I wanted two layers of leather is that I could put cool stitching around the outside of the thing. This is the part that takes the longest; it took me 42 stitches around the whole thing.
5. Add Snaps
To hold it together, I punched in some line 24 snaps.
6. Finish the Edges
I started the edges by sanding with 400-grit sandpaper, then I put some glycerin saddle soap on a rag and rubbed it into the edges. It came out looking like this:
That’s about it. So far it has stayed in my pocket one day without tangling.
