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 a [...]

Arduino sine wave with a digital potentiometer

21 September, 2009 (07:18) | Uncategorized | No 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 | 1 comment

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

17 September, 2009 (10:03) | Uncategorized | No comments

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

12 September, 2009 (20:14) | Uncategorized | No comments

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 pitting [...]

My current network

6 September, 2009 (15:43) | Uncategorized | 1 comment

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 some open wireless access and have [...]

This is what I get for modifying code

6 September, 2009 (14:54) | Uncategorized | No comments

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!
