DIY USB-Controlled Servo Squirter Water Pump

In this video, we'll show you a simple project where we connect a hobby R/C servo to a small water pump, and control both from the USB NerdKit. Using input from the connected computer, you can aim, and fire a stream of water. The video also introduces topics like Pulse Width Modulation (PWM), including how hobby servos share a common protocol (1.0 to 2.0ms pulses), and how to use the ATmega168 to generate these pulses.

where'd you get the pump?

[MrXtronnick]

I AM a NERD and im so proud of it!!! I love robotics and im working on a robotank build by only stuff i found around my house and some in the trash of a paint company i used to work !!!give me a visit on my channel and let's become friends!!!

You can also use a hobby RC fuel pump instead of the water pump. They're cheap and you can get them from any RC shop. This could be an alternative if you are having problems getting a water pump. Make sure you get a few feet of fuel tubing to go with it, since the valves on the fuel pump are sized specifically for that kind of tubing.

something more interesting pls

this information is the abc of electronics ... share in a million of abc electronics web site .

you should create and share something more cool ...

good job

Hi , where can i get this small water pump you are using...thank you

[consolehacker54]

cool we have the same laptop :D

Maybe you can help me out. I want to set up a security system. I have the means to do that however I don't want to spend a ton of money on a tilt and pan cam. So I decided the best I can do is to use 2 programs. 1 for video, the other for moving my homemade pan and tilt. I am on a mac and would love just a simple way (gui) to control the pan and tilt i'm going to rig up. Basically I need to be able to move the servo using my computer. Any ideas would help.
