As a ‘tall desk operator’ (I try and stand 30-50% of each day, at least) I’m always intrigued by tall-desk hacks and mods, be they mechanical, electronic, or simply design enhancements and improvements. An Alexa-enabled voice-controlled desk has so many options to build upon, and I thank Dirk Grappendorf for sharing this project over on the Makers, hackers, artists & engineers G+ community!
This work extends the IKEA-Hackant project from Robin Reiter , who reverse engineered the controller board of an IKEA Bekant motorized adjustable table. He added an Arduino board and four buttons to the controller, so that you can store two table positions and easily recall them.
You can find Robin’s work in his GitHub repository . This Video shows his project development and the operation of the modified table.
Robin has already explained how the Bekant controller and his Arduino circuit works. So please refer to his documentation, if you want to learn more about this. In a nutshell: the current table height is received as packets on a LIN bus and the table motor is controlled by simulating presses of the original up and down buttons of the controller.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
