Re: mysql-server

To fix it, I downloaded the .zip version, grabbed the new .jar, added it to my project as an external JAR, and boom! I had to change the DriverManager info, but that was really quick. What a day! haha

Re: Controlling Brushless motors with a PWM/Servo Driver

Ok, so I will have to have an ESC for each brushless motor I attach to the 12C board? The reason I am going this route is because there are not enough ports on the raspberry pi that control use PWM. I would like to have as many as I can. Most of the ports will be use for other things in my project s...

Controlling Brushless motors with a PWM/Servo Driver

Hey guys! First of all, this will all be controlled by a raspberry pi. I was wondering if I can control a few brushless motors with the: "Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface - PCA9685" http://www.adafruit.com/product/815 I did some research and have experimented with controll...

Re: Connect two Raspberry Pis Wirelessly

I found this XBee thing that allows some sort of serialized transmission that I think I am looking for. I would like some verification that this is something that would be useful to me, from someone who has knowledge in this matter. http://www.cooking-hacks.com/documentation/tutorials/raspberry-pi-x...

Connect two Raspberry Pis Wirelessly

Hello! I am looking for a way to connect two raspberry pis wirelessly without the use of a router. I need to exchange a sequence of numbers to another pi, which is controlling a mini R/C car I am building. I would also like to send video over the stream, so that I can see through the eyes of the R/C...

Connecting to a PC

I am looking for a way to connect a raspberry pi to a pc. I will need to transfer small amounts data as fast as possible because it will be messing with the mouse coordinates. I also need to be able to connect to a touchscreen that is at least 20" with multi-touch. Any ideas?
