Sequential Flasher Christmas light strings by SCR

Here is a simple circuit for sequentially flashing Christmas light strings or other similar low-power lamps. The socket symbols may be single bulbs or sockets for lamp strings. The load must be capable of operating from DC since the SCRs rectify the line voltage. The SCRs must be sensitive-gate types and must be able to handle the load current and line voltage. The 1uF capacitors are non-polar film types. A fuse is indicated and a GFI type of outlet is recommended.

Christmas Tree Lights Flasher with 7812+LM380

This is Circuit Christmas Tree Lights Flasher with 7812 for supply regulator
and IC LM380 for Signal generator dirve relay on-off the lamp two set.
detail other see circuit.

The Christmas Tree Lights Flasher Circuit. It is Lamp flasher that interesting by use IC LM380 for Oscillator generator
model Pulse Osc. Low Frequency for use relay switch give Lamp 220V. A lot of get for the accuracy of the circuit then must use IC 7812 DC voltage REG 12V And R1 use fine winking speed of all light bulb. The detail is other see in the circuit better sir.
