In those days small firms used to make DPM’s digital panel meters with 7107. In 1987 when i got a opportunity to design a DPM for a firm, I put the 555 clock in place CD4009 clock shown in intersil, to derive the -5. I created this design to study Eagle Editor. It is not tested by me, but all concepts/modules have been used by me in my designs earlier. It ought to work with some tweaks.in reference to: "Analog Dial AVO Amps-Volts-Ohms meter - del00023" - Analog Dial AVO Amps-Volts-Ohms meter -...

LM3914 Dimming Flashlight

2009-09-25T14:51:00.001+05:30

The LM3914 is used as the basis of a 10-step variable brightness current-regulated white LED torch! A modification in this design may be to separate the LED Anodes from V+ pin 3. Give a Zener supply at 3. The LED anodes must be supplied a square wave from a LM555 pin 3 at around 200 Hz. This will reduce the dissipation as it is switching. LM555 can drive 500mA which is sufficient.in reference to: Silicon Chip Online - Circuit Notebook (view on Google Sidewiki)
