Hi,
I am working on a clock project at the moment and I need a little help with the circuits.
It is to be built inside a Haywards pickled onion jar with an internal diameter of 3 3/4 inches and a height of 4 1/2 inches, there is a picture of the jar in question attached here.
The clock is based on 168 LEDs.
These LEDs are split up into 12 panels, which will be pressed against the inside of the jar. I have included an image of the proposed layout, the numbers represent the sequence in which the LEDs should turn on. The black lines divide up the panels. Imagine the strip as if it wer glued on the outside of the jar and in proportion.
I have a circuit that I designed in circuit wizard to count the seconds and keep the LEDs lit (so all 60 second leds would be lit at the turn of the minute, all 60 minute LEDs at the turn of the hour and all of the LEDs in the clock at 23:59:59). An identical circuit, taking its output from the end of the seconds circuit can be used for the minutes. I have included a copy of the Circuitwizard file for those who are interested. There are also three pictures of the circuit here, here and here
There are a number of issues with this circuit though:
Is there any chance you guys could help me out?

The clock is based on 168 LEDs.
- 1 LED for each second in a minute. Total of 60
- 1 LED for each minute in the hour. Total of 60
- 48 LEDs, two for each hour, split onto an upper and a lower level
These LEDs are split up into 12 panels, which will be pressed against the inside of the jar. I have included an image of the proposed layout, the numbers represent the sequence in which the LEDs should turn on. The black lines divide up the panels.

There are a number of issues with this circuit though:
- It takes its timing form a 555 timer, if the 555 timer is off by a fraction of a second, the clock could be a few minutes off by the end of the day.
- I cant work out how to make it reset, so once the LEDs are lit, they stay lit forever (or until the battery goes). Also, this makes it impossible to carry the seconds over to the minute side
- None of that matters anyway because the circuit boards required would be massive and there is now way that they would fit in a pickle jar. Even after modularising the circuit I cant get a single one to fit in the jar, never mind the 24 modules that would be required, plus the LEDs, 555 timer, battery and the inductive charger I was planning to put in the base.
Is there any chance you guys could help me out?
