Time Circuits and Keypad - ALL SOLD

10 Time Circuit Units were sold. We agreed with the electronics company that made the first 10, to make 10 more. This time the unit is smaller so it is the same size as used in the movie. The pictures on the right show:
The cardboard model we used to design the metalwork.
The new time circuits in a right-hand drive DeLorean (the unit is designed for a left-hand drive car)
The time circuits front and rear views.

The price for this item is $1500 and includes shipping to the US and Europe. The unit contains 39 16-segment displays, a microcontroller interface to a keypad and custom-made metal casing.

The Time Circuits feature in all three movies and no DeLorean Time Machine is complete without them.

We wanted our Time Circuits to be fully operational. That means that the time and date on each row can be set by the keypad.

Months of development work went into these circuits. There isn't a commercially available driver that replicates the time and date display. So, we had a custom microcontroller built to drive the displays.

We are using 0.5 inch high 16-segment LED displays on our new Time Circuits and this determined the overall size of the unit.

The movie Time Circuits were hard-wired and the keypad didn't really drive the date. When Doc enters a date, he only types the year on the keypad.

We've had to imagine how the other information was entered. On our Time Circuits, you enter each part of the date and time separately. The emphasis then moves to the next part of the display.

The Time Circuit chassis is made from custom-built aluminium. The electronics within the unit include 39 16-segment displays in three colours red, green and yellow, a custom-programmed microcontroller and display drivers. The unit runs from a 12V supply. The keypad is fitted to the base of the chassis and has a numeric keypad and illuminated lights and switches.

This unit draws less than 0.5A but should be run from a secondary battery if you plan to leave it on at a car show.
