This system is intended to give data back to the pilot on things such as Current draw, Voltage, Motor RPM and such. It uses a PIC microcontroller for the brains, and a small TX RX module to get the data back to earth.
The module will be on the free radio band of 418 or 433 MHz.
It will eventually have a serial link to connect to a PC.
Further detail will be posted as soon as they become available.
This is a start to the telemetry project. It is to ensure that the measurements get done accurately.
It was decided to build a unit based on the principle of commercially available units, but with a discharge facility built in. The unit will measure up to 100 Amp, and 50 Volt.
It will display the current, voltage, current wattage, and the overall average wattage used in a session.
Further details will be posted as soon as they become available.
A two function switch designed to switch accessories in a model aeroplane, car etc.
The switch was originally done to switch a camera in a glider, with the throttle stick of the transmitter.
The camera couldnít be interfaced with normal motor switches, it needed a high side switch for power and to advance the film.
The unit was therefore built with two miniature relays, and a PIC controlling it.
It is infinitely adaptable to the needs of most customers.

This came about when I got hold of a Weller 24V iron minus the transformer and control system.
I decided to do a controller with a PIC16C74, driving a 2 by 8 LCD display to give the current temperature, and the setpoint temperature.
Since it was for my use, I didnít include any scaling of the temperature readings, just a direct output value of whatever is in the register.
I will shortly be providing the source code and a schematic of this project on this site. The control has served me well for about 4 years now.
This is a small controller that takes any channel on your radio, and reverses the pulse. It gives the normal and the reverse pulse output. The reverser gets used in models where you run one control surface with two servos, and the physical layout prevents you from using normal servoís.

This mixes two channels into one another at three preset rates, 25-75%, 50-50%, 75-25%
For use with two channel radios and vtail or delta wing models.
Price: $11 US
Assists you in finding downed models, by checking for missing pulses.
Two versions are available, one that only checks for lost pulses ( No pulse for +- 1 Sec)
And one that you can switch with a spare channel on your receiver, it also looks for lost pulses, in case your receiver goes out of range.
Price: $11 US
These give a direct bargraph readout of the state of your receiver battery. Low current consumption and small size make them ideal for aircraft use.
Price: $8 US
Small and lightweight, using the latest MOSFET technology.
Can handle up to 20A constant current, up to 10 cells, with the BEC handling 1 A up to 8 cells.
Price: $28 US
