After being sick for no explainable reason, I finally got around to posting some pictures of the progress I’ve made in getting information from the powerbase.
I set up a testing area in my room so that I could run some cars and still be close to my desk. A piece of plywood is pretty high-tech, I know..
I found a power supply in my basement that works great for the time being. The Aux Port is really just a typical phone jack outlet, so I wired a phone cable up to this:
Underneath the electric tape is a small fuse which should prevent me from blowing up our precious powerbase if there is any accidental mishaps/crossed wires. This is a 9-pin serial adapter that is typically found on PC’s. However, Mac computers don’t have these kind of connections (only USB/Firewire) and need this Serial-USB adapter:
I got this a while back from Amazon, and it works great!
I wrote a quick sketch that plots the data coming from the powerbase. This shows the input from the hand throttle and you can also see the strings of numbers on the bottom which is the data in its raw form. Now just have to figure out the interesting things we can do with this data!
I also finally received some electronic samples I ordered a while back. The black chip is called a “digital potentiometer” and acts as a digital version of a hand throttle. I hooked this up on a Basic Stamp II Development board I had lying around (Similar to Arduino). It receives data from processing and sends a signal through the plug I’ve wired up. Sweet.
Also got the beginnings of a network/internet controlled car basically running (still buggy). Things are finally moving along!
