I feel that I can write a how-to on just the steps that I took to solve the clock issue and ignore the discovery phase or I can tell the painful truths with all of my embarrassing hits and misses as I work my way to a final solution or call me long winded. For the mechanics, this Instructable will read like a diary. But most importantly a broken Flip Clock (that is what I will be working on) The radio and alarm works. Small scratches in the 100% pure fake plastic wood grain case 3. I can live without this one too for awhile because I can set the time without it. Knob for setting the time on the side of the case. I can live without it because I can move the nub with my fingers and I won't need that option for where it is going. Missing two knobs (possibly a future instructable): a. Here comes the bad news - we brought it home and ended up falling in love with the clock radio so steampunking the item was out of the question and restoration became the priority.

These GPIOs will be configured as required with pull resistors or fixed voltages via software.Would it be cool to find an old flip clock to steampunk? Good News and Bad News: Good News: My chance came a few days ago and I bought a 70s Lloyds Solid State clock in an antiques flea market for a whopping $5.00 …could not pass it up. The correct wiring to connect the different electronics is as follows:ġ: For ease of connectivity, all pins of rotary encoders are routed to GPIOs. Raspberry Pi 3 A+ Raspberry Pi 3 Model A+ Two NeoPixel RGBW LED sticks have been included in the front of the FlipClock in order to provide nightlight and light-sign functions to the device. Tactile switches are placed under the bar to detect when it is pressed. This bar can be used to trigger the nightlight by default, or to stop/snooze the alarm when it has been triggered. One of the encoders is used to control the volume (up/down/mute), whereas the other encoder controls the audio device (FM Radio/Spotify/OFF) WheelsĪ snooze bar is included on top of the FlipClock device. The used encoders can detect steps in both directions, and include a built-in switch. Block diagramįor the user interface two rotary encoders have been used. For the FlipClock device two units of the PCB have been used: one to control hours and minutes flaps, and another one to control weather flaps. The current version of the PCB can handle up to two flip digits at the same time. The PCB has an UART interface for the abstraction layer protocol. Additionally, the PCB also handles the IR transmitter and receiver to detect flap transitions and the limit switch for automatic synchronization of the axle.

The FlipDigitController PCB includes a microcontroller and drivers to control the stepper motors. Additionally, a limit switch is placed close to the gears to synchronize with it each turn. An IR transmitter and an IR receiver are palced on the top and on the bottom of the flaps to detect transitions. The movement of the digit is achieved with a stepper motor and two gears. All the flaps are mounted within those holders. The axle is placed inside the bearings holding two flap holders. Additionally, a snoozer bar, two rotary encoders and a RGBW LED strip are included for the user interface.įind additional info about each design in:Įach flip digit consists of a support structure with two bearings. The device consists of three 3D printed flip digits, a PCB with integrated drivers for the digit controlling stepper motors and a Raspberry Pi 3 A+ with 3W speakers to run the main code.Īll the mechanics and electronics are mounted within an 3D printed elegant cover. The Flip-Clock is an old stylish, classic alarm clock with up to date features, such as automatic time adjustment, weather forecast, FM radio or Spotify playback.
