oscillator provides the clock signal for the counter and the rate can be adjusted
with the 500K pot. Two additional Schmitt Trigger inverters are used as a
SET/RESET latch to control the counting direction (up or down). Be sure to use the
74HC14 and not the 74HCT14, the 74HCT14 may not work due to the low TTL input
trigger level. When the highest count is reached (1111) the low output...(circuit

Audio Controlled Christmas Lights - Here is a simple circuit to control 110VAC
things such as Christmas Lights with low voltage audio. Be careful, high voltage
AC can kill you. “The basic Idea was to have Christmas lights flash with the
music. In my design I use an ordinary amplified computer speaker, a diode bridge,
and a ‘CRYDOM’ SSR (Solid State Relay). In order to increase the time that the
lights were on as well as protect the SSR I used a Diode Bridge to rectify the
signal from the amplifier circuit.”...(added 02/09) |

Bang Bang Thermostat is Simple & Efficient - 11/06/97, EDN-Design Ideas:
Perhaps the simplest and oldest feedback loop is the nonproportional,
all-or-nothing, "bang-bang" thermostat. Fully turning on a heater when the
temperature is below setpoint and off when it's above setpoint is a
straightforward example of a servomechanism. Yet, elementary and crude as
servomechanisms are, examples surround us in virtually every household-room
thermostat, clothes dryer, oven, and aquarium heater, to name a few. The version
in Figure 1 preserves the best features of the old bang-bang: low cost,
simplicity, and efficiency combined with setpoint stability.....(design idea added
