Here is a Neon Flasher circuit (untested) for a user request at Elex Quna. This can be built into a switchboard or a gadget for indicating Live Power.
D1-C1 form a simple half-wave rectifier, The Cap charges to peak voltage and can store charge for a long time if there is no bleeder. So while building [...]

Three Phase Solid State Relay
This is R-Y-B three phase 40A 440V AC Solid State Relay with 3-30 V DC Control Signal. It has Built in HeatSink and Fan. It is good for Controlling a Bank of heaters. This model could go upto 120A with SSR’s in parallel for Proportional Control. Solid State Relays SSR.
This is a Contacter replacement, it [...]
Tacho Counter for Speed and Quantity Measurement
This was a Custom Built Product for Converting a 10-100 V Signal from a Motor Tacho to pulses, to indicate the distance moved by Conveyor belt with Job Material. The Digital Indicator would indicate the speed and the Mechanical Counter would Log Quantity of Materials Moved.
Analog Blind Dial On Delay Timer
It is called analog dial timer as it has no digital display, but the chip is digital it is CD4541. It is Mains operated, you could make on-delay or off-delay. By changing the caps and resistors or with even dip-switches you could get timing of few seconds to many hours. Circuit is Analog Timer 4541 [...]
