Homemade LED Analogue Clock v3

Update of my analogue clock, this version shows a pattern demo once a minute, and shows power up demo once an hour, digital readout without the previous bug where some leds flashed & Power up demo which shows all pattern demos

Poor video quality due to camera & Flicker barely noticable.

I see the clock shows 8;30 and the hours hand is still at 8, when it should be in between 8 and 9. How about at 8;59? Will it still show 8? That would be missleading to read the time.

@McGuywer The hour hand moves into the mid postion at 32 mins past the hour, so at 8.32 the hour hand is half way between 8 and 9.

your in the big time now, found this link to your vid on tomshardware main page. Good work with the clock

@obscured021 Thanks

I know you said it would be expensive, but I'd like to know a ballpark of how much you would have to sell it for to make it worthwhile to you

[wellyb00t]

@flybriur parts between 40-60 pounds, the bulk of it were the LEDs, as for the time taken to build/program it to be worthwhile you would need to sell for £200+

@wellyb00t I think 15min. and 45min. would be more adequate as the turning points (round to nearest).

Anyway, the idea of the clock is brilliant, more so as it is perhaps the only affordable way of building huge solid state analog clock displays.

I may try and build a simplified version of this (a smaller PIC), by splitting the hand in 2 (rather than 7), so 8+3 pins for hand select and 1 pin for hand length select. That is 12 pins for display, just like an ordinary 4 digit, 7-segment display.

This is really nice.

Why not sell them as a kit with all parts?

@ZombieShogun

Its difficult due to the amount of time soldering it takes to build, to make it worth my while would make it quite expensive....having said that im thinking was building a smaller version around 30cmx30cm to try and sell on ebay.

you should sell these id buy
