Reminds me of the ones you used to see on modems.

News - New Product Friday: Oh Fu… | about 2 weeks ago

Spade, this is the code I used. I’m not sure how to format it correctly for the comments so if you want me to email it to me, let me know.

I built one to “cure” the dog from getting into things I leave accessible by mistake when I leave the house. It’s going to make an appearance at work after the dog learns.

Static electricity? Have you tried shielded wire?

News - Maker Faire San Mateo 201… | about 3 weeks ago

Hamvention rocks! Haven’t been to one in the last seven years, but when I lived in Ohio, I went to them every year.

I’m surprised SparkFun doesn’t at least have a small booth there. Most of the attendees are definitely the kind of people that would shop at SparkFun.

Now if someone would just modernize Hare Arena so it didn’t look like 1970 on the inside…

Not bad for $30!

Product SEN-11171 | last month

I have a question about the servo connector. The manual says this is for a button press on the transmitter. What signal is the camera expecting? Is it a 0 to 180 degree transition? or is it a simple on-off pulse?

Tried capturing serial images by using the arduino servo “sweep” example but I’m not getting consistent results. I assume I should get one picture per sweep, but I’m getting pictures at random times.

What gives?
