Yesterday I received a bunch of really nice robot parts from Parallax.
While I didn't purchase these parts, they're also not really a gift.
Parallax wants some Spin code modified to work with some of their new hardware. I've been sent this hardware with the expectation I'll get the code working with it.
Hex Caster is my attempt to come up with some play on the word "hex".
I plan to use this PCB with both my hexapod projects.
Here's the top of the board.
Below is the bottom.
The servo banks are broken into groups of six.
About a month ago I purchased hexapod kit off ebay.
Yesterday as a break from program my Mini Hexapod, I started putting together this larger one.
Something I've wanted to do for a while is to be able to digitize the data from cheap sensors with a 7-segment display.
I decided to give it a try with some USB charge meters.
I purchased four of these meters.
I opened up one of the blue ones and probed the pins to see how the 7-segments were wired.
Ugh! Someone I was trying to help with a cheap L298N h-bridge pointed me to this video from TheRaspberryPiGuy.
At 10:41 of the video he plugs the 5V line into his RPi's I/O pin.
