Giant Modular 7 Segment Display

If you like the idea of the project then please do like this Printable using the heart button above. It helps me to create new projects. Thank you.

Build a large and very bright seven segment display to show numbers, words or animations for your own project. Example code and wiring diagrams are included for both the Arduino Nano and Wemos D1 Mini (ESP8266).

Personalise it to your needs by including more hardware, such as thermometers, motion detection, buttons etc or use a Wemos D1 Mini to connect it to WiFi and show dynamic readings from the Web or your local network.

List of items used in this project and where to find them: 

■ WS2812B LEDS 60/m (1 Meter required per digit): https://geni.us/5mWS2812B60m

 A microcontroller, either 
■ Elegoo Arduino Nano (x1): https://geni.us/ArduinoNanoV3
or 
■ Wemos D1 Mini and LLC for Wifi and IoT Control (x1): https://geni.us/wemosD1
Logic Level Shifter (74AHCT125): https://geni.us/74AHCT125-LLS
 ■ Power supply 5v (x1): https://geni.us/5vPowerSupply3A (Budget at least 1.5amps per digit, 3.6 amps if your going to turn them all on bright white simultaneously). 
■ Barrel Connector (x1): https://geni.us/HighAmpDCBarrel
 ■ Plenty of M3x6 bolts: https://geni.us/NutsAndBolts
 ■ 5mm Solid Acrylic: https://geni.us/SolidAcrylicSheets5mm
 ■ 3mm Semi-translucent/Frosted Acrylic: https://geni.us/OpalFrostedA4Acrylic
 ■ 3D Printer Filament: https://www.3djake.uk (I used 3D Jakes PETG)

 To connect the electronics either: 
■ Projects PCB from PCBWay: https://geni.us/Giant7SegPCB
 ■ Wago style connectors or similar: https://geni.us/Wago221

Optional radio control add-on: 
■ Radio Receiver: https://geni.us/315mhzReceiverMoment
 ■ Radio transmitter fob: https://geni.us/315mhzTransmitter-4b
 

 Some wood for the frame. I used four pieces of pine 20x68x436mm (x2) and 20x68x381mm (x2) 
To work out the wood lengths for different thickness of wood please take a look at the cheat sheet I made for you here: www.diymachines.co.uk/
 

 ■ Glue (I used Wood glue and Gorilla Glue): https://geni.us/Gorilla-Glue 

These are some of my favourite tools I use and can recommend: 
■ Battery-powered glue gun: http://geni.us/BoschBatteryGlueGun
 ■ Bosch Bit Driver: https://geni.us/Bosch-Screwdriver
 

 I use a Prusa MK3S for my projects and highly recommend both it and the Prusa Mini. If I inspired you to take up 3D printing please consider purchasing a printer via this link: http://shop.prusa3d.com/#a_aid=diymachines
