If having trouble attaching the flaps, it may help to slightly back the rotor off the shaft for a bit more clearance. The rotor should interlock with the rotor end cap. Install the rotor end cap onto the motor shaft, with the protruding nub facing the motor body.Use 2 M3x10mm bolts and lock nuts to attach a motor to the motor mount.Make sure to pause before the last layer to swap the original color back in. If you don't want to color in the numbers manually, you can pause the print after the first layer and swap to a different filament color. The numbers on the flaps are inset by 0.2mm, so these parts are recommended to be printed at a 0.2mm height. Recommended layer height is 0.2mm or lower. The parts are designed to print without supports. Will need to cut the switches off and solder leads to the C and NO pins Endstop failure detection - shuts down if homing takes over 2 full rotations.Steppers turned off when not moving for power savings.Automatic calibration once per rotation using mechanical endstops.Runs off of Arduino's USB power - no separate power input needed.US DST support - clock automatically skips forward/back 1 hour as needed.RTC module keeps track of time even when unpowered.Automatic time setting on sketch upload.Use these tips to find a starting position with easier memo and tracing.Arduino-powered clock using split-flap mechanical displays. 3 and -3) you can ignore those while tracing AUF as they will cancel out. If your memo includes two numbers that are the inverse of each other (eg.If any edges are matching centres, it may be easier to memo that side as there are less numbers to memo and trace.The result should be all back edges and center facing 12, and all front centers and edges facing the same direction but not necessarily 12. The AUF can actually be done before the other edges instead of at the end, so take advantage of the pins you have in your scramble. With the L pins up and R pins down, execute the fourth value from memo on the R dials, and with the L dials, make the center match the R edge.įinally, with all pins down, execute the AUF memo on any dial. With D pins up and U pins down, execute the third value from memo on the top dials, and with the bottom dials match the center with the U edge. With the R dials, match the center with the L edge. With the L dials, execute the second value from memo. Now put the R pins up and the L pins down. With the top dials, make the visible center match the visible D edge. ![]() With the bottom dials, execute the first value from memo. SolvingStart with the two U pins up and D pins down. This number is the AUF - the final number in memorisation.įlippingYou MUST do an x2 flip before beginning the solve. Finally, turn 1 unit clockwise, ending at 1 o’clock. Point 5 units anti-clockwise to return to 12/0. For each edge in your memo, point to where the centre would point to after doing the inverse of that move.įor example, if the center is pointing to 3, and the memo is -2, 0, 5, -1:įirst point to 3, the current orientation of the center. Point to where the center piece is currently facing. You should now have a sequence of four numbers.ĪUF tracingAlthough you can calculate the AUF with arithmetic (sum the inverse value of the center with the normal values from the edge), I prefer to trace the center piece with my finger as I’m bad at arithmetic. Remember in the order DRUL.įor example, if the D edge is at 5oclock and the center is at 3oclock, memorise -2. Steps Edge memoFor each edge D, R, U then L memorise how that dial must turn to match the center. I call it four halves due to the pin ordering. ![]() ![]() Therefore memo and tracing is easier IMO. I propose a no flip method for clock which only requires 1 calculation (unlike others which require more).
