This is plainly not safe. A desk with memory needs to require a continuous button press to keep advancing the desk, so that if the operator or someone gets caught in the desk and can’t push the stop button, it stops as soon as pressure is released.

It would probably be better to just implement continuous current (proportional to torque which is proportional to force up/down) limiting on the motor, that would prevent the desk from pushing up or down at a force that could injure someone. Not sure if this is directly controlling the motor or just communicating with the actual motor controller. If the motor controller is separate it may already do this.

Hah! I am in the market for a standing desk and am 95% sold on the IKEA Bekant. Just waiting to move to commit to the purchase. I wasn't keen on the crank but I figured I could live with it. This is a nice and fun addition :)

I had the ikea one and this one: https://smile.amazon.com/VIVO-Ergonomic-Adjustable-Controlle... The vivo one has been far better in features and reliability. I had to replace the ikea one because it started only going down and not up.

If you still have the Ikea one, that was caused by a fairly wide-spread issue with the power bricks. They'll replace them under warranty with just an email with some info about the brick.

IKEA has a new standup desk called IDÅSEN: https://www.ikea.com/us/en/p/idasen-desk-sit-stand-black-dar... It can be controlled via Bluetooth with an app on your mobile. It is a much better option in comparison to Bekant in my opinion. The tabletop on IDÅSEN is much thicker too, making monitor mounts safer to install. If you are on the market for a standup desk with good value, pay $100 more and buy IDÅSEN instead of…

[…] If you are on the market for a standup desk with good value, pay $100 more and buy IDÅSEN instead of the Berkant desk mentioned in the Tindie campaign. Given the prices it gets at, why not just go for a non-ikea desk e.g. a basic Jarvis is actually cheaper than that.

In many markets, the options are extremely slim to buy good alternatives. Ikea is almost everywhere - and even in countries where they are not present (I lived in two), businesses exist that can get you their products from neighbouring countries at a 20-25% markup.

The IKEA standing desk seems to have a safety key that needs to be plugged in for the desk to move.

Correct, the desk will not move without the key inserted, even with megadesk.

So THAT is what that is for... I have had some of these Bekant tables, never understood the reason that thing needed to be plugged in.

I have a Jarvis standing desk right now and I'm very happy with it, but I've recently gone on a home automation bender and want to automate all the things. In particular, I'd like to be able to control the desk remotely so that I can add it to a Home Assistant script that fires via an Alexa skill.

This seems a bit silly, but I have a whole configuration that I use for coding that is different to the config that I use for (say) gaming - different monitor settings, change in lighting, open/closed window shades etc. I'd like to adjust desk height similarly (I have two keyboards and mice, one positioned below the other one on a pull-out keyboard tray).

So, any ideas on where to start automating this particular kind of desk? The controller is a sealed unit and my google-fu is lacking when it comes to finding the protocol used to communicate with the desk itself.

EDIT: Found this: https://github.com/sarahkw/deskctrl/blob/master/schematics/r... not sure if my desk is a JRV1 or not yet but will find out.

FWIW, I would say that knowing how to design boards makes me MORE willing to buy other people's boards. Coming from a more mechanical background, I don't look forward to the tedium of reviewing and modifying all the footprints of "standard" sized SMD parts. I like making music effects for friends, and branching out to things related to motor control, LEDs, sensors, etc. I prefer to have them pick and placed for me. S…

Your comment made me realize that I only enjoy building things when they have a component of learning, or when it's something I haven't done before. I have a similar problem where my vision goes blurry at the center if I focus near for long, but I've found that magnifying glasses help with that because they change the focal length. > I would be interested in seeing some of the designs, you've always been an interesti…

Yes, yes, yes and yes.

This comment came at the perfect time since it's something I've been thinking about all morning and it even relates to PCB's :-)

I think I'm the same way. I have bare boards here (PCB designed and came back from fab), a stencil, paste and trays of parts. AND a customer and a damn healthy profit margin.

So why haven't I assembled, tested and shipped the boards I should have almost a week ago? Well, that's the question and I think your answer crystallized it perfectly for me. The fun part of solving the problem and coming up with a solution is done. Actually building and testing these things is BORING and I have to force myself to do it even though I know shipping just two boards will cover this month's car payment.

I was thrilled and excited to ship the first ones: precision analog electronics, a four-quadrant multiplying DAC and a domain I enjoy working in (machine control). But now that we're up to Revision 4, I am so effing bored with it.

I recently got myself a commercial-grade Workrite Sierra HX Electric standing corner desk to make what appears to be a pretty permanent WFH situation more pleasant. Safe to say I won't be volunteering to go back to the office anytime soon.

You can even kneel on the ground with this one, because it goes as low as 22.5" as per BIFMA G1-2013 requirements.

It seems to have the same up/down interface (panel and app) as the IDÅSEN from IKEA, which is interesting. Exactly this one: https://www.linak.com/products/controls/dpg-with-reminder/

I just realized that I have a problem, where I think "why would I pay $50 for a PCB that I can design and make myself?" and then conclude "therefore nobody would pay". Maybe I should start selling some of the PCBs I made.

I think this must be true of software, too; I have thought, from time to time, "that'd be neat, but there's no way I could sell it", or even just "that'd be neat, but nobody else would want to contribute" (for FOSS). But... the same logic would imply that a lot of things shouldn't exist that do. Why do any of the BSDs exist, why does redox exist, why are there so many programming languages, why are there so many package managers, ... maybe, if I think it's neat enough to build, other people would want to use it. Maybe, if I would pay for it (if only someone would sell it), others would, too.

If you are OK with adding more hardware, you could use a physical device to press the preset buttons. Something like this - https://www.amazon.com/SwitchBot-app-controlled-device-mecha...

I bought the Bekant a couple of years ago, and then an Idasen just a few months ago. I highly recommend you consider the Idasen instead. It's double the price and the legs are arguably uglier, but overall it's so much more sturdy than the Bekant. There's no more wobble at the top, the desk surface itself is twice as thick, and the lever for raising/lowering it is way better than the buttons on the Bekant. I could tel…

The Idasen does look a lot better. Do you think it would handle a move (or two) well?
