Smart Meter Fun (Part 1)

My current apartment has one of those ‘smart’ electric meters that can communicate with the power company directly over the power lines. A few months ago, I found out about a smartmetertexas.com, w...

Flying Experiments

I managed to go flying last Friday after work. Since no one else was able to come along, I decided to do some experiments with the camera. Last time I mounted the camera on the rear window pointin...

CC2500 Project (Part 6) - Reorganizing

This post is mostly about software, so I’ll keep it short. I re-arranged most of the code so it hopefully makes more sense. My goal is to make the main code hardware agnostic. That way if you want...

CC2500 Project (Part 5) -- SPI Problem Solved!

So I wrote last week about getting UART working on the MSP430G2533 but having major problems with the SPI interface… I was so frustrated that I caved in and purchased a Salae Logic analyzer. It fin...

CC2500 Project (Part 4)

I haven’t been working on this project lately, but I finally got back to programming yesterday. I got the MSP430G2533 which has both hardware UART and SPI. This one will act as a bridge between the...

CC2500 Project (Part 3)

Here’s an even smaller update! Since the MSP430G2452 doesn’t have a hardware UART, it’s not very useful in communicating with the computer. I could use the bit-banging method to get 2400baud, but...

CC2500 Project (Part 2)

Here is a quick update on the project’s progress. Today I was able to get the radio libraries working better and actually set up constant radio communications across a room. I also wrote an RGB le...

CC2500 Project (Part 1)

So I’ve started working on another project… This one includes microcontrollers and radios. The “goal” of the project is to have a very cheap 2.4GHz radio module and libraries to use it. I used the ...

West Texas Thanksgiving

So I had a few days off work for thanksgiving… Most people usually visit their family during that time, but due to a late change of plans, I ended up doing something else. I found out that about 6...

Time-Lapse Experiments

I recently started experimenting some more with time-lapse videos while moving. I bought a suction cup mount for my DSLR and tested it out in my car. ...
