Electronic Speed Controller for R/C Models - Here's how you
can make an electronic speed controler (ESC) for your remote control
car, boat or even an airplane using an old servo and some MOSFETS….
(electronic design added 10/06) |
|
Electronic Thermostat Relay Circuit - Here is a simple
thermostat circuit that can be used to control a relay and supply
power to a small space heater through the relay contacts. The relay
contacts.... [Bill Bowden] |

F84 Miniature Real-Time Controller - Build a simple real-time
controller with PIC16F84 running at low power X-tal 32,768Hz. Daily scheduler
for 6-channel resided in 64-byte EEPROM can easily be preprogrammed
using Nigel PicProg. RTC2.C provides user programmable set current time
without the need of recompilation. Fixed bug on minute conversion!.... [Wichit

Fader switch uses inexpensive controller - 12-Nov-09 Issue of EDN
Control the brightness of an LED or incandescent lamp.... [Design Idea by
William Grill, Lenexa, KS] |
|
Fan control - As we begin to enjoy those lazy hazy days of summer,
the most important thing on most of our minds is how to keep cool during those
hot days. For some of us that means turning up the old air conditioner and
sipping on a nice cold glass of our favorite soft drink. However, we often
forget about an equally important.... [Radio Amateur Society of Norwich] |

Fan Controller Adapts to System Temperature - 09/25/97 EDN-Design
Ideas Any piece of electronic equipment--whether it be a lab instrument,
an audio amplifier, or a PC--that relies on a cooling fan to control internal
temperature is a potential source of noise pollution or even hearing damage.
Most of the time, the fan's noise level is probably much higher than
necessary, because it has enough capacity to move.... [Design Idea by Kerry
Lacanette, National Semiconductor, Tucson, AZ] |
|
Fan Dual-Controller - Each fan turns off when the temperature drops
5 degrees below its turn-on temperature. For example, if the dial is set to 80
degrees, the fan turns on at 80 degrees and turns off at 75 degrees.
This prevents the fan from cycling on and off rapidly, which would occur if
the fan turned on at 80, started to cool the cabinet, and then immediately
turned off at 79. ….(design added 11/08) |
|
Fan Speed Controller - Simple circuit for fan speed control based on
thermal feedback. To reduce product noise. Design idea was rejected! Years
later companies are making millions from such circuits.… [Jim Haggerman,
Hagerman Technology LLC] |
