HC11 Controls the Stepper -

High Speed NiCd Charger for Electric R/C - A few years back, I
published a design for a Low Cost Thermal Peak Detection Charger. Since
then, I've designed several other chargers, in my ongoing quest to...

High-Rate Electronic Speed Control with BEC and Brake - This
electronic speed control (ESC) for brushed motors combines the features of
two of my earlier designs. One was a high-rate 30A ESC with a brake, and the
other a high-rate 12A ESC with a BEC (receiver battery eliminator circuit)…

High-Rate Speed Control with Brake - Many designs for high-rate
speed controls have been published. Most require two 8-pin integrated
circuits (ICs) or one 14-pin IC. Many designs suitable for home construction
…. [Stefan Vorketter] |

LED Bargraph Optical Tachometer - For the electric R/C enthusiast,
a tachometer can be a very useful piece of equipment. When I first built
this tach back in 1995, it was essential, as there were very few
off-the-shelf electric R/C power systems that just worked….. [Stefan

Low Cost Thermal Peak Detection Charger - The electric model aircraft and
car industries have produced a bewildering array of field chargers for NiCd motor
battery packs. These range from simple 6 or 7 cell chargers consisting of a resistor
and mechanical timer, to more complex chargers with peak detection, cycling, and the
ability to handle 36 cell packs.... [Designed by Stefan Vorkoettert] |

Miniature High-Rate Speed Control with BEC - My first Speed 400 powered
plane was the Sydney's Special, an 80% scaled down version of Vernon Williams' Fred's
Special, as published in the November 1991 issue of Model Airplane News. I chose this
project because I was really happy with my original-size 46˝" Speed 600 powered Fred's
Special. The scaled down version has a 37".... [Designed by Stefan Vorkoettert] |

Miniature High-Rate Speed Control with Brake - Many designs for high-rate
speed controls have been published. Most require two 8-pin integrated circuits ( ICs)
or one 14-pin IC. Many designs suitable for home construction are fairly large (some
as large as 2" square). Many do not include a brake....(electronic construction

Multi Channel RC using CMOS - This transmitter has no separate on/off switch
because the joysticks switch the battery terminal. The receiver has a bigger motor to
drive the wheels and a smaller motor to drive the steering which is not proportional.
There are two speeds in forward and one in reverse. You could add an extra channel to
the receiver by using the spare latch.... [Reverse engineered schematic by Stepan
Novotill] |
|
On/Off Motor Controller with Brake - Modern electronic speed controllers (ESCs)
are very efficient, but they still have some drawbacks. An inexpensive ESC with two
IRFZ40 MOSFETs has an on-resistance of 14 milliOhm. At 20A current, this means a
voltage drop of 0.28V, and a power loss of 5.6W. Furthermore, to build an ESC with a
brake generally requires an expensive P-channel MOSFET.... [Stefan Vorketter] |
