| LED or Lamp Pulsar Circuit |
| 2012-02-09 19:15:23 |
Astonishing effect 4.5V supply This circuit operates a LED in pulsing mode, i.e. the LED goes from off state, lights up gradually, then dims gradually, etc. This operation mode is obtained by a triangular wave generator formed by two op-amps contained in a very cheap 8 pin DIL case IC. Q1 ensures current buffering, in [...]...

| Fuse Monitor Indicator |
| 2012-02-01 19:16:49 |
Description: The idea for this project may have come to me in a flash of inspiration, and its a very simple way to check if a fuse has blown without removing it from its holder. Notes The simplicity of this circuit uses just two components, but with just one resistor and an LED this circuit [...]...

| Lie Detector Circuit #2 |
| 2012-01-28 19:15:43 |
This lie detector circuit can be built in a few minutes, but can be incredibly useful when you want to know if someone is really telling you the truth. It is not as sophisticated as the ones the professionals use, but it works. It works by measuring skin resistance, which goes down when you lie. [...]...

| Circuit Troubleshooting |
| 2012-01-24 19:16:01 |
Short notes about Circuit troubleshooting. - Check the circuit for mechanical failures, like disconnected wire, broken vias on the board, and connections between two adjacent vias which are not to be connected. - You should compare values of components and their connections with values and connections between components on the schematic. - Measuring DC voltages [...]...

| Brightness Controller Circuit For Small Lamps and Leds |
| 2012-01-17 07:15:34 |
Switch-mode driven 1.5V bulb, Portable unit – 3V battery supply This device was designed on request; to control the light intensity of four filament lamps (i.e. a ring illuminator) powered by two AA or AAA batteries, for close-up pictures with a digital camera. Obviously it can be used in other ways, at anyone’s will.IC1 generates [...]...
