|Spot welder test|
On the right there is a picture of an early test. You can see the capacitor in the background, on the breadboard there is an Arduno Nano and the Nokia LCD display. We are using scrap steel "electrodes" at the moment but will possibly change this with real tungsten welding electrodes.Oooh, and obviously no XBees involved this time.
RC SurferYears ago I bought a so called "RC Surfer" for cheap (you have to google this because mine is disassembled and I can provide no photo in action).
Cheap were also the contents of this RC controlled surfer. There was a motor driver with a relay, a 27 MHz radio control and a servo controlling the rudder. The power control was only "on" and "off" and the servo reaction to the input on the remote control was at least working.
There was no feedback of voltage or temperatures and no extra features like light etc.
The first test run worked quite well and the next addition will be the rudder control with a new servo. At the moment I'm using a joystick out of a scrap PS2 control - later I will command the RC Surfer with my android phone and a bluetooth connection. If that doesn't work, I will use a XBee/ RC combination with a traditional remote control.
Possible features might be telemetry which sends data like current used, voltage, temperatures, cam etc. Or what about a water canon?
