No. Miscellaneous Projects Description Flags
01A Better Volume Control A volume control using a linear pot that is much better than most log pots. Also a better balance control.
07Discrete Op-Amp Class-A Output. Intended as an experimental device, but it works extremely well
14Power Amp Bridge Adapter A conventional adapter for bridging power amplifiers PCB
Jan07
20Simplest Ever Bridge Adapter Use this simple method, and avoid external circuits
42Thermo-Fan For Amp Cooling Use a 12V computer fan to keep your amp cool. Uses a simple but very effective diode temperature sensor (Updated) Jan02
46Thermal Shutdown + Amp Thermal Protection What happens if your amp gets too hot? It will probably self destruct, or at least reduce the life of the power devices. Add this circuit to either turn the amp off, or activate a cooling fan. This is similar to one I use on my own system Mains Wiring
54Low Power FM Transmitter Not really suited for "Bond, James Bond" spying activities, but will be useful to retransmit from the hi-fi to another FM receiver nearby, or use it as a wireless microphone or guitar link. Not in the same league as the commercial offerings, but much, much cheaper. Mar02
57SIM - The Simple Version Ah!  The simple SIM must be a compromise, you say.  Well, actually the complex version is a compromise - this is the real thing. The smallest variation in amplifier performance will create a signal that the SIM (Sound Impairment Monitor) can react to with startlingly accurate reactions to even the smallest variations in an amplifier.

73Hi-Fi PC Sound System A Hi-Fi PC Speaker system? You have never heard your MP3 collection, CD or games sound so good. If you could buy one, a system of this calibre would probably set you back more than the PC itself - The sound is very, very good! PCB
126PWM Dimmer/Speed Control This circuit is a versatile PWM controller for low voltage DC. It can be used to control 12V LED lighting, DC motors, heaters, or anything else that responds to PWM current control. The circuit uses readily available parts, and can even be controlled via C-BUS or other automation systems that support 0-10V control. PCB

ABX
ABX Comparator
Building on the basic concept of Project X, this contributed project utilises the original techniques of a true ABX tester. It can be made as a simple AB tester, or build the random remote for full ABX testing.
Aug02
XA-B Switch Box Yes folks, Project "X" has arrived (I just had to have one!). This is a contributed article / project, and might be confronting to some who steadfastly maintain they can hear minute differences between amplifiers. Now is your chance to prove it :-) Aug00
