What the heck, Popular Science

25 September, 2009 (20:50) | Uncategorized | 1 comment

This post is really a bit of a challenge to an old school science mag. I’ve been pondering some new writing projects. On one hand I have previous venues that I can work through, but I’m interested in new challenges. While I’m pursuing some previous successes, one idea on my brain is to contribute to [...]

Arduino sine wave with a digital potentiometer

21 September, 2009 (07:18) | Uncategorized | 2 comments

I wanted to create a sine wave to test my ignition system with a better test signal, but I didn’t have a DAC handy. I did have a spare digital pot from my RGB doorlock project. There are several examples of DACs being built from resistor ladders, so I figured I’d give it a shot. [...]

EDIS igniton with GSXR Coil on Plug coils

19 September, 2009 (22:06) | Uncategorized |

Despite my lack of piston rings, I’m still moving on my project bike. I picked up a set of three GSXR coils for about $10, and decided to test them out with a ford EDIS-6 ignition controller. The EDIS is a stand alone electronic igntion – but it responds to timing controls if/when the main [...]

Fix a RJ-45 connector with a pair of zip ties

This is a nice little hack I found on Instructables today. I usually replace cables with broken clips, but it’s not always an option. This fix uses a pair of nylon zip ties to create a new clip. You’ll need some good cutters or some good knife skills to pull it off. Be careful cutting [...]

Fixed site, plotted to do more on the 850

I repaired my old theme, which appears to be happily working now. Meanwhile I’ve been working on my xs850 a bit. Last week we pulled the cylinders and ended up breaking a cylinder ring. I was a bit sad about it until I scrubbed the worst cylinder wall I have. It appears to have some [...]

My current network

My home network runs on the following bits of hardware: 20/2Mb cable modem Juniper Netscreen Firewall Cisco Catalyst 3500 switch Nortel Wireless security controller Multiple Nortel Access points Here’s a rough diagram of what’s going on with the network. The netscreen has multiple connections to the cisco, thanks to my multiple security zones. (I provide [...]

This is what I get for modifying code

6 September, 2009 (14:54) | Uncategorized |

Took some time to update the code I use for the blog front end of this site…. And it broke the theme I’d modified the crap out of . I’ll get it fixed soon!
