Winter Project: 700c Wheelset – Complete!

700c WheelsetFinished my wheels in an evening! Building wheels is fun. I’m trying to set up my red Schwinn as a super reliable city bike – no external cables and with internal wiring for the lighting. This wheelset should be good for fast pavement rides, hopping curbs, and dirt/gravel trails. I’ll post more about the bike once all the parts are in. But for now, here are the specs on the wheels:

  • Front Hub: Shimano DH-3D72 Dynohub. I got two of these for around 60% off the regular price. One is on my vintage Hercules (Which I need to photograph and post). These are good hubs.
  • Rear Hub: Sturmey Archer S2C Kickback 2-speed hub with coaster brake. Pedal backwards a little bit to switch between 1st and 2nd gears. No Cables!
  • Rims: Alexrims Adventurer
  • Tires: Continental Speedride. Widest low rolling resistance tires I could find. Good for concrete and off-road.
  • Spokes/Nipples: 14g stainless spokes with brass nipples. Both in black.

I combined my birthday and holiday gifts to buy parts for a new wheel set for my city bike. I’m super excited to put them together. It’s the first completely new wheel set I’ve built. I’ll post the completed wheels with specs.

Not oft seen together!

H.G. Wells’ Time Machine passing a Storm Trooper who is talking to a belly dancer. How many places in the world do you see that?

D&D update…

The boys are holed up in the Room of Fire for the night! Hope they can sleep and heal up. One of them is bloodied and one is dying. Holy wow!

Family portrait!

Here’s a family portrait of all the puppets that I’ve made over the last several years. Thought I’d get a photo in before a couple leave at Christmas.

3-D modelling on Android

Tinkercad and 3dtin works on Android through the Firefox browser. Tinkercad will load models, but working on them isn’t really practical. 3dtin fares somewhat better. Editing simple models is possible. Screen shots follow:

Project of the Day: New Blog for my Kid

Set up a new blog for one of my kids today. It can be found here: http://theeclecticartist.com

He plans to post video games he has programmed, artwork, lego creations, bug photos, stop-motion videos, and books he has created. He’s a pretty creative kid. Check it out some time.

Project of the day: J’s Stop Motion Animations

I fixed J up with some stop motion software on my unused Droid phone today. He took to it immediately. I’m hoping to get him fixed up with sound effects, voices, and music at some point. Here is one of his longer silent films. The speech bubble at the beginning says “Me again.” The green brain slugs have been featured in several of his short films. Keep in mind that he just turned 9 yesterday. :)

Project of the day: CNC Mill Electronics

I’ve finally been able to make a little time to work on my CNC mill/router project.

I have a dedicated controller PC built from three old PCs. Older desktops are best as they don’t have all the power saving features that interfere with real-time processing and control. It runs Ubuntu Linux 10.04 LTS from LinuxCNC.org. The OS comes as a live CD that you can try out to make sure it will work with your hardware before you commit to installing it. It installs a basic system that has everything you need to run a CNC machine with EMC2 (control software). It’s also free, which is pretty great!

The controller hardware and motors are from Xylotex. I have a 3-axs controller and 425 oz. motors. I tested the software and hardware out today. Below are the results:

The next step is to build the actual mill table. This will probably wait until warmer weather arrives.
