Standing Desk

A Raspberry Pi- and Arduino-controlled standing desk: Control your LogicData-powered standing desk remotely. The project components (hardware components, hardware wiring, software components and installation) are described in detail below.

Hardware

Required Components

  • Jumper wires and breadboard
  • Soldering equipment
  • Raspberry Pi 3 (or similar)
  • Arduino Micro (or similar)
  • Female 7-pole DIN circular socket (to connect to handswitch)
  • Male 7-pole DIN circular plug (to connect to motor controller)

Wiring Overview

Wiring

The diagram for the wiring of DIN connections (left) was created by Borislav Bertoldi. Colors correspond between the diagrams.

Software

Building Blocks

  1. DeskControl.ino is the main program running on Arduino with the task of controlling the signal going to/from the motor controller and handswitch.
  2. desk-server.go is a small Go program which exposes HTTP methods for controlling the desk and runs on the Raspberry Pi:
    • Adapted from David Knezić's project
    • curl localhost:9987/up or /down or /toggle
    • Configure UP_HEIGHT and DOWN_HEIGHT with your preferred standing and sitting height (or extend the logic yourself). Default values: UP_HEIGHT=90 and DOWN_HEIGHT=10.
  3. ssh_desk_handler.py is a small Python program which enables controlling the desk via SSH (integrate or adapt it for your own use case).

Installation

First, install go (tested version: go version go1.15.3 linux/arm). See instructions for Raspberry Pi here.

Add the following to your ~/.bashrc:

export PATH="$PATH:$GOROOT/bin"
export GOROOT=/usr/local/go
export GOPATH=/home/pi/go/

Clone and build the project, and add desk-server to init.d:

git clone https://github.com/visini/desk.git ~/go/src/github.com/visini/desk
cd ~/go/src/github.com/visini/desk
go get
go build bridge.go
sudo ln -s ~/go/src/github.com/visini/desk/init.d/desk-server /etc/init.d/desk-server
sudo update-rc.d desk-server defaults

Optional: Configuring shairport-sync

The Raspberry Pi also serves as my shairport-sync host directly connected to my external audio interface sitting in the cable tray of my desk.

Note: If you are using an external audio interface, be sure to adjust /usr/local/etc/shairport-sync.conf accordingly (see also here for more information). To find out the hardware device id, run alsamixer and press S. Then configure shairport-sync.conf accordingly (assuming sound card device id=1):

output_device = "hw:1,0";
mixer_control_name = "PCM";
mixer_device = "hw:1";
