Amp interface

 

The amplifiers are also made by myself. In the original design by Elektor there was no option for an Ir-remote. Connecting the amplifier’s and other audio related equipment to the Joshua bus , controlling is now possible with everything available on the bus.
The preamp was working with logic levels +9V and -9V, this made the interfacing a little bit complicated and extended.

Rc car turning & breaklights

 

This is my HPI Savage x4.6 with Dodge charger ’69 body painted in the well known Dukes of hazzard colors. To make this model realistic i want old fashion American taillights that are controlled with the remote controller of the car.

Rc Car ignition killer

Designed on request, rc nitro car ignition killer.Will kill the ignition of a rc-nitro car by hand trough the 3e rc-channel or if the voltage drops below a programmed voltage.
Schema / source / handleiding etc (rev.1)
-Schematic and pcb designed with Eagle 4.15
-Software created with Bascom-avr

Revison 2: Some receivers are working on an higher voltage then the default 5V. The BEC systems are direct connected to the battery so the voltage can rise up to 7V. Added very low drop 5V voltage regulator and extra resistor in the servo in line to limit the zener current.

Pcb_animatie

My submission for the Mcs electronics design contest 2007 and i have won the 5e price with this design.
This device will light up LED’s if the car is breaking, monitor the reception and quality of the received signal from the transmitter and the battery strength. With setpoint learning function.
