Lightwave bindings adapted to WLF Liquid Force kite board


Lightwave makes a great pair of bindings, but after purchasing them, I realized that my Liquid Force WLF kite board uses non-standard 6.5inch screw spacing. The screws for the Lightwave bindings are spaced at 6in apart.   Continue reading Lightwave bindings adapted to WLF Liquid Force kite board

Logitech Unifying Mouse Receiver Integrated into Lenovo W500 Laptop

The nano receivers that come with cordless mice are awesome, because you can leave them in the laptop all the time.  Worked great on my Macbook, but it sticks out a little too much on the Lenovo Thinkpad W500.  Therefore it gets caught when sliding the laptop into a bag, and eventually damaged my first receiver.  I’ve always wanted to integrate the mouse receiver into a laptop, but could never justifying all the work for a proprietary controller.  Finally Logitech has released a receiver that works with several of their devices, which they dub “Unifying Receiver”.  It was time, but I didn’t realize that to get to the USB port contacts I would have to completely take apart the laptop.  I’m very happy with the result and performance.

Trail Mix and Other Goodies Dispenser


Sticking our grubby hands into the bowl of trail mix has probably increased our immunity, but I finally had a chance to make something better with a scoop.  Unsatisfied with the dispenser offerings at the store, I resorted to making my own, as usual.  An airtight container is key to keeping the trail mix fresh.  I was tempted by the hopper type dispensers that had a twist knob which dispensed measured amounts every time the knob was turned.  However, the inexpensive ones ($50) looked cheap, and didn’t seam to have a good airtight seal.  Nor did I believe that they would be able to handle some larger items in the trail mix.  These Clik-Clak containers provide a nice airtight seal, but still have a quickly removable lid.  To test out my idea about how the plywood stand would work, I first made a cardboard template, used it to adjust the dimensions, and then as a template for the plywood.

Speed Reduction for a Belt Drive Sewing Machine

Every time I use a sewing machine, it’s for some really thick or tough material that requires a lot of punching power, and is easier to sew at a slow speed. Most machines run a little too fast for my purposes, and don’t develop enough power at slow speeds. They rely on speed by building up inertia in the flywheel to provide the necessary power to sew through thicker fabric. In order to lower the speed and increase the power, the motor needs to be geared down. Since most old sewing machines use a belt, this is not difficult to do using a double pulley system. My sewing machine is a 1950s Nechi BU with zigzag stitch.

iPad Leather Case

This is my first attempt at making a leather case for the iPad. It’s also the first time I’ve worked with leather, so it’s kind of rough and unfinished, but that’s how I like it. Thanks to John Sanders from www.joxasa.com for helping me pick out the leather and excellent design advice.

Electric Violin Wall Case

The NS Designs Violin is practically a work of art by itself. Unfortunately, the case it comes with is not so practical. As with any violin, the shoulder rest must be removed when the violin is stored in the case. Installation/removal of the custom shoulder rest requires tightening/loosening two thumbscrews, sliding the shoulder rest post out of the violin’s body, and folding the post flat with the shoulder rest. That’s not difficult in itself, the problem is that every time the shoulder rest is reinstalled, it has to be repositioned the same way, which is not easy with 3 degrees of freedom. Etching some markings would make it a little easier.

The violin is used at home the large majority of the time, so the solution was to make a storage case which did not require me to remove or reposition the shoulder rest.Due to their solid wood body design, electrical violins like this one are less susceptible to changes in humidity and temperature. Thus storing it outside the case is not a problem. Still have to be cautious, especially if the bow is stored outside the case.

Flashback - Backpack, Camelbak or Jersey Integrated LED Bike Flashers

I often ride bikes that end up not having working LED flashers, either because it’s a friends bike who doesn’t believe in safety, mountain bike, or the batteries are dead again. Since I always bring my camelbak with me on rides, I designed some LED flashers that are integrated into the bag.

Towel Rack

I needed a towel rack to fit on the back of the door, and allow the towel to be slipped off the end. This makes it easy to grab the towel or hang it up just by sliding it off or on the end. I had scrap dowel like pieces of nice outdoor wood from a broken patio umbrella. That would be useful for the bar from which the towel would hang. The support for the bar was made from other scrap wood ends.
