Sidereal clock circuit — progress!
I’ve been kicking around the idea of making an accurate sidereal clock circuit for years now. I’ve discussed it all before, but the basic idea is that I want to be able to create a circuit that oscillates at 32857.715Hz … Continue reading

A slice of Pi
I have a Raspberry Pi on the way. Since I’m mostly an Arduino shop, I have to think about how to interface my existing goodies with the new board. This one looks cool:R Pi to Arduino Shields It makes use … Continue reading
Bringing the Home Theater together with Plex
I tried XBMC as a Home Theater PC “OS” — it certainly did a fine job of presenting movies from our LAN in an easy-to-navigate manner. But, because Netflix was on another box, and Tivo on yet another, the HTPC … Continue reading
EyeTV is the new Tivo
I’m in the process of updating/rebooting my home theater. The most complicated part of this is the Tivo/Live TV replacement. I considered trying Hulu, but because I already have a HD-ready off-air antenna, I decided to see whether I could … Continue reading
Tivo – The Big TV Reboot
I’ve been increasingly dissatisfied with my home theater setup. Primarily, the home theater is designed around the TV and a 5.1 Dolby Digital audio system, so it’s tuned for movies and TV shows and videogames (to a much lesser extent … Continue reading
Working on my communication
I’m beginning to realize that most of the big electronics projects that I have right now are going to require a more serious level of inter-device communication than most of my previous stuff. Any kind of UAV/quad is going to … Continue reading

Networked Arduino
I picked up two separate Ethernet solutions for Arduino while I was at Maker Faire; an Arduino Ethernet Shield, and a Nanode 5. Once I got them home (and got the Nanode soldered together), it turns out that they use … Continue reading

Insane URL-fu
I had an interesting use case. I needed to get some data out of a database, and then return the result in a graph. So far, the thing is not so interesting. However, there were a few twists. First twist, … Continue reading
Eye-Fi — easy Arduino internet access?
The Arduino has multiple ways to get online, from ethernet shields to ones with built-in RJ45 jacks. Then there’s all the Xbee / Bluetooth type stuff or even the USB-to-serial bridge, if you are OK involving a PC. But “easy” … Continue reading

Web app idea
I think that I would like a more personal version of digg. For instance, over the years, I have tagged (by sending the links as emails to my friends) several xkcd strips as “Like”. But there is no way for … Continue reading
