Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:
Fading LEDs - 2-strips of LEDs fading in a complementary manner 9 Volt Battery-operated portable unit (added 9/04)
Fading Red Eyes - can be used to slowly illuminate and fade a pair of red LEDs (added 4/02)
Flashing Beacon - (electronic Circuit / Schematic added 10/04)
Flashing Flashlight (Stepan Novotill)  - Pretty nice design for a cheap consumer grade flashlight. The power switch was not exactly as shown since there was an option to have the lamp on solid.  (added 2/05)
Flashing High Intensity LED 3rd Brake Light - This circuit to make a flashing3rd brake light assembly was designed to be easy to locate all the needed components and reasonably in expensive to build. (added 4/02)
Flashing Light Circuit 1 - (electronic circuit added 4/05)
Flashing Light Circuit 2 - (electronic circuit added 4/05)
Flashing Light Circuit 3B - (electronic circuit added 4/05)
Flashing Neons NE 2/NE 51 - In this circuit, one, two or three neon indicator bulbs can be made to flash in sequence at rates determined by the R and C values. In the single stage circuit, using one lamp, the capacitor charges through the resistor until the ionization potential of the neon is reached (about 70 volts) and....(added 4/02)
Flashlight Timer  - A nice design which even turns off if the pushbutton is held depressed or jammed a long time. Not re-triggerable while the light is still on though (added 1/06)
Flashy Christmas Lights - (electronic circuit added 10/05)
Flicker Lamp - Having bought a cute little ‘paraffin lamp’ from a cut price shop, I decided to make it a little more interesting. Its battery powered of course but its continuous shine and simple on / off ‘wick control’ did not make for anything like a close simulation of the real thing. So, I replaced the on / off control with a variable potentiometer and I added flicker!.....(added 04/04/04)
Flickering Fire Effect - This simple circuit uses four low-Wattage colored bulbs and four fluorescent lamp starters to make nice flickering flame effect. (added 4/02)
Flickering Fire Light - This may well be the world's only discreet logic circuit to generate truly random output. It makes an excellent candle flicker light for your Halloween pumpkin, and looks much more authentic than a shimmer light wherever a good a simulated flame effect is required. I do not guarantee the accuracy or safety of any information herein.  (added 2/05)
Flickering Lights - Halloween flickering lights  (electronic circuits added 11/06)
Fluorescent Inverter - Build this 20 watt Fluoro Inverter,  it drives two 20-watt tubes or a 40-watt tube!….(electronic circuit added 04/09)
Fluorescent Lamp Inverter - This inverter is very easy to construct, reliable, and even powerful enough to light up a 15W florescent tube (if you cool your transistor well). The only hard-to-find piece of this baby is the so-called yellow inverter transformer. It's a miniature high frequency transformer that has a 25mm x 20mm x 5mm ferrite core, 30 turns of primary, 15 turns of feedback, and 250 turns of secondary all concentric, wound on plastic frame than wrapped with a 'yellow' adhesive tape. If you can't find it in your local electronic shops then search for old portable rechargeble florescent lanterns since they have at least one yellow inverter. Of course you can wind a handmade transformer which would do the same but it is a very difficult task when you don't have an original to inspire and it will still need an appropriate ferrite core. ….(design added 11/08)
Fluorescent Lamps Ballasts and Fixtures - (circuit / schematic added 2/03)
Fluorescent Light - How to build a 4-Watts Fluorescent light using a disposable camera, powered by one 1.5 Volts battery. (5/29/2006)
Four Channel Dimmer Rack - (electronic circuit added 7/03)
Four DIPs provide as many as 80 sequential-LED outputs - (Design Ideas - EDN, 8/21/2008  A simple circuit uses HCMOS parts and adds one 74HC540 to multiplex the outputs of two 4017 counters for as many as 80 outputs. (electronic design idea added 9/2008)
