This is the robot I quickly built to demo the Low Voltage Motor Driver. If is based off the Mr. Basic platform and MSP-430 Launchpad. It has a 6.4V lithium battery as the main power source which feeds into the voltage regulators on the Launchpad.
For direction control a top mounted servo spins a Sharp gp2y0d810z0f IR sensor. The sensor has a single data line which is pulled low when a object comes within 10cm of the sensor.
Most of the code for the hardware is already written. Just need to finish the controls and it will be ready for a video.
Here is a link to the code’s page.
I will be uploading a video demoing the code. Have to build a tiny robot first.
They just arrived today! This weekend I will solder one up and if it works I will start selling them.
I finally think I have a version of the motor driver that I like. I tweaked the traces around the 470uF cap to make the ground path better. I also changed the nSleep jumper header from a 2-pin to a 3-pin. The user can hard wire the nSleep high or low.
I finished up the PCB for the Motor Controller Booster pack. The PCB is all open source and you can download the files on the project page.
I finished the first physical version of the msPROBOT just in time for Maker Faire. I have the majority of the demo code written and I will post it when I test the code. All the basic library functions are written. Just need to make a main program that strings it all together.
There is more information and PCB files you can download at the msPROBOT project page.
Do not have time to do a full write up right now but here are some juicy pictures.
So I just finished building my first Super Boost. It converts 2.2V – 4.5V to a steady 5V source. This is perfect for charging a cell phone or any other device that charges via USB by using 2 AA batteries or a single cell lithium battery.
The project page is here and the DIY page on assembly is here.
Today I updated all the parent links at the top menu and adjusted some of the links around.
I also open sourced my old Atari Video mods which you can download off this page.
If you check out the PCB projects you will find that each one now has a change log file associated with it. This will help document what changes between each version of the boards.
