Are there any desks that one has uses and really recommends? I'm not entirely sold on motorized desks, so suggestions for mechanical ones?

I have two jarvis desks. The extended reach ones. So far they have been excellent. Used for over a year now.

I wonder if this could be built with an esp8266 or esp32 instead of an arduino.

The main change would be to the power supply, as the esp8266 has a far higher (~300mA) peak current than the ATTiny814 used (~3mA). Currently, an LDO provides 3.3V from the 24-35V motor supply. This would need to be changed to a buck DC/DC regulator, as a larger LDO at this voltage would need too big a heatsink for the case.

You should be just fine with a cheap lm1117 and no heatsink, that's what most people use with esp's. Also that's peak current from the radio, which for IOT things is generally very short.

EDIT: Wait I meant from 5v, nevermind!

An esp32 would enable so much cool features. Like control by bluetooth/wifi, apple homekit integration, ...

I can't think of any reason to control my desk over the internet or via Bluetooth. If I'm not at my desk I don't care how high it is, if I'm at the desk and want to change it a button is much more convenient than using my phone.

Been using a Jarvis desk for a few years, have one at work and the exact same model at home. Can definitely recommend them. They aren't wobbly at standing either. My friend had the ikea one and it was such a pain getting warranty stuff since they wanted him to haul the thing back to the store over an hour away.

Yeah the thing I like about Jarvis is that they don't get wobbly near the limit of their extension like some of the other standup desks I've seen. I'm 6'5" and I have a thick anti-fatigue mat, so I have to raise it very high.

On top of that I also have a 42" TV on a monitor arm and an attached keyboard tray, and still no wobble.

Ikea's standing desks aren't that great. They wobble a lot and then anything attached to it wobbles too. Still looking for the perfect heavy-duty standing desk and heavy-duty VESA arm combo. I don't want anything on my desk moving unless I am moving it myself. To put it this way: if a desk is $500 and wobbles slightly (meaning if I touch the desk or type, my coffee jiggles and waves are seen) or is $1000 and the desk…

We have "UpliftDesk" standing desks and they seem pretty solid. I haven't used it standing but I can't wiggle the desk up/down at all.

I have an uplift desk frame with 4 legs and using my own desktop made from my parents old dinner table. Perfectly stable.

Well, on the one hand, it is great to have a replacement for the original controller. At a previous employer I had a Bekant with the stock controller, and those darn things are dreadfully unreliable. We had enough of those desks to get good reliability statistics... and the statistics are awful. So an open source replacement is great. That said: Who the heck needs a motorized desk????? When it came to spending my own…

wow - to everyone debating crank vs motorized:

2 desks

This has received the infamous HN hug of death. Any chance anyone has a working archive link?

Whatever happened to The Coral Cache? It seemed like such a great idea, but I have a 0% success rate with it. I suppose I've answered my own question, but did it ever work? Am I using it wrong?

And if it's simply that it can't fetch overwhelmed sites any better than we can, then could we help it by pinging it automatically for any link submitted to HN, enabling it to populate its cache before the hordes arrive?

Someone mentioned it on my repo a few months back. I think the space constraints would make it very challenging to make a drop-in replacement that fits in the original housing.

Of course, with a new housing, the sky is the limit :) But that wasn't the main design goal.
