hobbyists, students & inventors: |
|
Mains Operated Christmas Star: (electronic Circuit / Schematic added 10/04) |
|
McMurtrie's Self Powered Flashing LED: circuit which uses a LED as solar panel to charge a capacitor which flashes a LED, the
LED will blink when the circuit is placed in bright light (added 4/02) |
|
Message Waiting Flasher: This circuit starts flashing a neon light when the phone rings and continues flashing it until the
phone is picked up to remind you to check your voice-mail. The flashing neon light drives a voltage doubler (Q2) which keeps it flashing. Q1 ensures that the flashing is stopped when the phone is
picked up. Designed by
Andrew R. Morris (added 09/05) |
|
Mini Pocket Strobe Circuit: works from two1.5-Volt AA batteries, based on modified camera flash unit (added 6/03) |
|
Mini Strobe Light using LED: adjustable for flash rates between40 Hz and166 Hz, based on555 Timer (added 6/03) |
|
Miniature Strobe Light: (electronic Circuit / Schematic added 10/04) |
|
Multimedia Electronic Crib: microcontroller based light controller which generates sequence of day-night with light fading,
optional serial control interface, based on 87C51 (added 4/02) |
|
Multivibrator LED Flasher: (circuit added 7/02) |
|
No Hassel Lighting Third Brake Light: (circuit / schematic design added 6/06) |
|
Nocturnal Animals Whisker: A low-rate flashing lamp drives away undesired visitors Automatic on-off operation (added 9/04) |
|
Nothing Box: The nothing box is a set of nine relaxation oscillators. It blinks random patterns and looks cool. When the
voltage on the capacitors charge to 65 volts, the neon gas ionizes and discharges the capacitors to 55 volts. The frequency can be simply calculated from the exponential RC function, assuming that
the discharge time is neglible to the charging time. (added 6/-6) |
|
PC Parallel Port Output Capabilities: includes instructions how to connect a relay to PC parallel port (added 4/02) |
|
PIC16F84 LED Chaser $#: (circuit / schematic design added 6/06) |
|
PIC16F84 LED chaser: (circuit / schematic design added 6/06) |
|
Power line outage flashes red alert: 06/13/02 EDN Design Ideas / (schematic / circuit added 11/03) This
Design Idea expands on a circuit in a previous one to configure a power-outage detector with a flashing alarm (Figure 1, Reference 1). The circuit plugs into a mains outlet and uses
trickle-charged nickel-cadmium batteries. The green-LED monitors the presence of line voltage. The BZV55-C4V3 zener diode, D1 protects the batteries against overvoltage.. |

Pulsing third Brake lite for cars: (electronic circuit added 4/05) |
|
Rhino8 El Sequencer: (circuit / schematic design added 6/06) |
| Ringing
Phone Light Flasher:This is very useful in a situation were there is lots of noise and it is impossable to hear the phone, such as a workshop. Here is such a device. The ring detect part of
this circuit came from.... (added 05/07) |
|
Ringing Phone Light Flasher: when the ph1-rings, lights connected to circuit flash (added 4/02) |
|
RR LED flasher (alternating) : ASCII format (circuit design added 11/06) |
