LYFT is a sophisticated remote control for the famous IKEA BEKANT desk. It replaces the original controller and adds a number of useful features for more options and convenience.
Check tindie to see a fully assembled version of LYFT in action.
If you would like to read a featured article about LYFT you can find some on ikeahackers or hackaday respectively.
Features
Saving Desk Positions
The controller can store up to four different desk positions. These positions are easily accessable using the four memory buttons.
Display
The controller is equipped with a 3-digit 7-segment display which allows you to read the current desk height either in centimeters or inch. Furthermore, you can adjust the display brigtness as well as the display-on time. If the shown desk height is not accurate you can adjust the value using the 'level correction' feature by plus/minus 9 centimeters.
Audio Signals
In order to give some acoustic feedback the controller has a build-in audio transducer. The volume of the audio signals can be set in the settings menu but also be disabled.
Automatic Driving Mode
One of the most useful features is the automatic driving mode which allows you to move the desk to a saved position without holding a button all the time.
Safety Pin
On the basis of the original controller LYFT also supports a safety pin. The pin is needed to move the desk and to unlock the settings menu for changes. It is fully compatible with the original IKEA safety pin which is provided with the BEKANT desk.
Further details and how to use these features are described in the manual.

Questions
How big is the LYFT CTRL PCB?
It measures 43 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LYFT CTRL use?
43 parts, built around the LM358, LM7812, 1N4148W and BC846. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LYFT CTRL KiCad files?
From the mgkoenig/lyft repository on GitHub, at the commit this page was made from: the board is hardware/Controller Board/Rev A/LYFT_CTRL.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LYFT CTRL design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
