Microcontroller based running light controller

Another project by Rajkumar Sharma over at Electronics Lab, a lights effects board using common bulbs:

This project provides some lighting effect by the blinking pattern of the bulbs connected at its output. Up to 8 Bulbs can be connected in between connector CN2 to CN9 and AC power to control them should be connected at Connector CN10. DC Power should be applied at Connector CN11 in accordance with the polarity marked on this connector. Care should be taken while using this it as it contains Main Power on the board.
We can change the Blink pattern by the press of the SET switch and change the blinking speed by the press of the UP and DOWN keys on the PCB. Fuse F1 will protect the Kit from any possible short circuit and excess current flowing through it.

    Seriously, just put an Electronics Lab banner up and be done with it already.

    Has the internet really run out of other things worthy of mentioning?

    Actually, that is a nice looking board.

    Oh, I just treat them as DP’s sort of own Hugh Pickens / Bennett Haselton / Roland Piquepaille.

    The Kea Lab logo, no source code, and hiding the PIC model totally kills my mood.

    The programmability of light patterns is very limited, why would any serious display artist in the 21st century use this kind of thing? Oh, I guess they have an audience in India… For others this kind of project might be cute in the 1980s and in electronics magazines then, but I really don’t see anyone making practical use out of this in the long term. I see a lot more of controlled LED lighting in retail, and those won’t be controlled via mains.

    Too bad, their projects never did make me sit up and take notice. I just go ‘meh’…

    How about the isolation distance between Mains AC and DC?
    Just dangerous crap.

      There is a post from Nov. 8th about an 8 channel relay board (also from Mr. Sharma), which suffers from the same PCB layout issue.

    Nice board, and timely for XMAS!

    Richard.

    I did not read the current per channel, so you know what it is?

    Hey DP, what’s with this Electronics Lab never-ending promotion?

    thanks for heads up. electronics-lab filter in place for future!
