What is it?

An open source wifi enabled adjustable height desk controller.

Using a Particle Photon, this project allows you to remotely control your V3 GeekDesk. The V3 only comes with a simple up/down button panel and doesn't allow you to have any presets.

Using an HC-SR04 Ultrasonic distance sensor attached to the bottom of the desk and pointed at the floor, we can measure the height of the desk. Using a pair of opto-isolators tapped into the button panel we can control the desk. The buttons are connected to the desk controller through an rj45 cable. This allows up to connect to the buttons without doing any permanent modifications to the desk itself.

This project gives you the ability to get and set the height of your desk (in centimeters) using the Particle's REST api

What makes it special?

This is a much less expensive route to get your GeekDesk V3 to have preset height capabilities. It also connects it to the internet so you can control it from your computer anywhere, and also log statistics about your sitting and standing behaviors.

What's included?

If you select the 'PCB Only' option, you will only receive the Geekdesk controller circuit board. You will need to supply the rest of the components.

If you select the 'Kit' option, you will receive the following components needed to assemble the kit:

• One Geekdesk controller circuit board
• One HC-SR04 sonic distance sensor
• Two RJ45 jacks
• Two 220 ohm resistors
• Two 12-pin female headers
• One right-angled 4-pin female header
• One 2-channel opto-isolator.

What's not included?

• A Particle Photon. You can purchase this from https://store.particle.io/
