Universal IR Remote Control Tester - This tester consists of two
integrated remote control receivers whose outputs drive an LED to indicate
when a suitable infrared signal is received. To cover all current infrared
remote controls, one receiver (the TSOP1736) has maximum sensitivity to
carriers at 36 kHz, the other (the TSOP1738) to carriers at 38 kHz.….must

Universal RC5/RC6 Transceiver with PIC16F628 - This project is an
expansion from another project from this website. On the one side you can read
the RC5, RC5X and RC6 codes from remote controls on a LCD and on the other
hand you can send all thinkable RC5, RC5X and RC6 codes to a device. Besides
is for this project a PCB layout drew to make it still more easier for you.

Use a switching regulator controller to generate fast pulses -
13-Apr-06 Issue of EDN Switching-regulator-controller ICs can deliver
gate-drive pulses with rise and fall times of less than 2 nsec, making them
ideal candidates for laboratory pulse-generators.... [Design Idea by Mitchell

Voltage controllable LFO - This voltage-controlled LFO is based on
the PIC 16F684, which is a pretty basic chip. Nonetheless, this LFO has more
features than your average LFO. For a start, it can produce 7 basic waveforms,
and also includes a noise source. It can also morph its waveforms under CV
control, well beyond basic PWM....(added circuit 07/07) |

Volume Control has Log Taper - 11-Apr-02 Issue of EDN
Digital potentiometers provide a compact and convenient way to attenuate
audio-amplifier signals. However, most such potentiometers suffer from at
least one flaw a nonlogarithmic step increment. To avoid this problem, a
user must usually step the potentiometer in a nonlinear sequence to simulate a
logarithmic taper.... [Design Idea by Doug Farrar, Los Altos, CA] |

Volume-Control - Circuit of a digital volume control using six
discrete ICs, including a 5V regulator, is presented. IC1 (555) is configured
to function as astable flip-flop. Its frequency or period may be adjusted by
proper choice of resistors R44, R45 and capacitor C6 combination. Here it is
for 0.3 second period.….(Circuit design added 08/08) [Site is under
