1 watt fluorescent lamp night light - simple circuit that operates from 120V AC, uses chilly cathode 1W fluorescent lamp and RC community for present limiting, pdf file
LED Mood Light-weight - This circuit tends to make a good lamp which is reduced energy, runs amazing, and has a long life span, dependant on LEDs and operates from 12V DC
Flashing LED electricity indicator attracts lower present-day - flashes an influence indicator LED to maintain the typical present-day very low regular thirty uA from 3V, pdf file
Odd software of neon glow lamps: The Dimmer - neon glow lamps can also be employed only for their U/I attribute and never for creating light-weight
How do I deal with a buzzing sound coming from my dimmed lights? - Often every time a triac-based mostly dimmer controls a light-weight, it could create an audible hum from the light bulb or the dimmer by itself.
In summary, the Electronic Dimmer described right here offers a extremely trusted Manage section (from ten% to 95% of the ac sine wave). It may be used for lighting apps, or single-phase motor velocity controls, or any other sort of application circuit the place a trustworthy Manage stage is needed.
Retaining the light fittings and changing dichroic lamps and transformers with their new LED equivalents to create considerable Power cost savings. This associated calculating the life cycle and payback interval and testing mild levels in the 'mock-up' bathroom to be sure guest ease and comfort.
To elaborate, smoke fluid is a mixture of in between 10 to 75% glycol to drinking water dependant upon how dense the fog is ideal.

Trigger circuit check them out for stroboscopes - circuits which may be employed for triggering stroboscopes from exterior indicators
Other elements involve a photodiode and an op amp that monitor the ambient mild; a rotary potentiometer that sets the light depth; an LED bar array and Show driver, which suggest the light-intensity setting; a lightweight-dimmer-control circuit; plus a 16?two-character Liquid crystal display, which suggests the temperature of the two zones.
Generate a Cheapo Neon PSU - A simple but very responsible method of getting a touch of neon all-around your workshop. This device is built to operate straight from 240V AC mains ability.
