If this happens, get a new larger 7805 regulator and solder it to the master board. There is a sneak current path and the tiny 7805 5volt regulator on the master may burn out if all the other arduinos try to power from the USB voltage when the power supply is off. Note: The USB cable should be unplugged from the master arduino nano before turning off the power supply.

Make sure you dont install the dip switch and motor drivers on the master PCB. On the slave PCB, D2 and D3 are used for the dip switch and the motor driver. Note: The choice of D2 and D3 works because this is the master PCB and NOT the slave PCB. This will go to the pushbutton to decrement time. Solder on a pair of 10" long wires from the D3 pin and ground. This will go to the pushbutton to increment time. Solder on a pair of 10" long wires from the D2 pin and ground. Solder on 4 twisted wires that are about 6" long to the +6V, Gnd SDA and SCL for future connection to the other boards. Solder on 1 I2C 1.3k (or close value) pullup resistor between the RTC board Vcc and SCL.

Solder on 1 I2C 1.3k (or close value) pullup resistor between the RTC board Vcc and SDA. The Master board will be secured to the clock with a 3D printed bracket later.Ĭonnect the RTC Vcc to a +5 hole on the board.Ĭonnect the RTC Gnd, SCL and SDA to the corresponding names on the PCB. The soldered connections will make it secure. This RTC board can be hot glued or attached with double side tape to the master PCB. It will hold this time with the RTC battery.

The RTC is programed with the current computer time everytime the master Arduino is programmed through its USB. The Master Arduino board contains the Real Time Clock(RTC) board and an Arduino nano. This is a spreadsheet with details on the 3D printed parts:

The PLA spools need to be kept tight so the filament doesn't get bound up and snap while printing.

If you dont, the prints will become very thin.

The nozzle needs to be cleaned every so often.

If you dont, the parts will start lifting up from the bed or getting corrupted.

The bed needs to be leveled every few days.

I learned a lot about 3D printing on this project. The supports on the gear tubes needed to be clipped off. If you have access to a second 3D printer, you could go faster.Īll of the parts were printed at standard temperatures with 20% infill except for the 2 gear tubes which were printed with 100% infill and supports. If you print 2 a day, that's 12 days right there. Each clock module base plate takes about 9 hours to print. I would say it was around a month or 30 days of printing. It took a long time for me to do all of this printing on one printer.

It was sliced with the free version of Cura.

This whole project was printed on a $215 Creality Ender 3 Pro with PLA. you will learn some debugging skills too. There is a lot to go wrong when you are making 24 of something so. If you do this project, you will learn 3D printing, Arduino coding, schematic/PCB design and mechanical skills. I would say that this is a moderately difficult build but would be a very rewarding high school or college student project especially if you have multiple 3D printers. I highly recommend that you buy one if this is in your budget. They have a similar (and better quality) clock for sale called the ClockClock24. The Clock is inspired by a clock that I saw in a Boston store a few years ago by Humans Since 82. The clock can be adjusted to store different time zone offsets which are saved in the master Arduino EEPROM memory. The total price I paid to build this was about $500. Each clock face uses a custom Eagle designed PCB which can be ordered easily. It is composed of 3D printed parts, 25 Arduino nanos and 48 stepper motors. Between time displays, it shows moving artwork. This is a Digital Clock design that was built from 24 custom 3D printed analog clocks.
