Standing at your desk all day is healthier by far than sitting, but the commercial options tend to be expensive. [drivenbyentropy] had to contend with a heater right where the desk would go, but building an adjustable office desk to accommodate it turned out — well — gorgeous.
Two 18″ heavy duty 12 V DC actuators raise and lower the desk with a 600 lbs static load capacity and 200 lbs of lifting load each. One actuator is actually slightly faster than the other, so instead of working out something fancy, [drivenbyentropy] simply extended the cable length on the faster actuator to disguise the difference.
Framed with some standard 2×4’s and sheathed with plywood, the massive four by eight foot desk has twelve ball-bearing drawer slides in the legs to add stability and smooth out height adjustments. Because of its size and having to build around the heating unit, the desk is stuck in the room since it does not easily come apart. There is, however, easy access to the two electronics compartments for troubleshooting!

No two words can turn off the average Hackaday reader faster than “Nixie” and “Steampunk.” But you’re not the average Hackaday reader, so if you’re interested in a lovely, handcrafted timepiece that melds modern electronics with vintage materials, read on. But just don’t think of it as a Nixie Steampunk clock.
No matter what you think of the Steampunk style, you have to admire the work that went into [Aeon Junophor]’s clock, as well as his sticktoitiveness –he started the timepiece in 2014 and only just finished it. We’d wager that a lot of that time was spent finding just the right materials. The body and legs are copper tube and some brass lamp parts, the dongles for the IN-12A Nixies are copper toilet tank parts and brass Edison bulb bases, and the base is a fine piece of mahogany. The whole thing has a nice George Pal’s Time Machine vibe to it, and the Instructables write-up is done in a pseudo-Victorian style that we find charming.
If you haven’t had enough of the Nixie Steampunk convergence yet, check out this Nixie solar power monitor, or this brass and Nixie clock. And don’t be bashful about sending us tips to builds in this genre — we don’t judge.

This Clock Knock Block has a bit of everything; milling, Arduino, sensing, solenoids, and plenty of dirty puns. Just knock on the box or on the table right next to it and the time of day will be played back to you in a series of crisp, clean knocks. A big part of the fun here is that the box is a musical instrument.
If you take a look inside you’ll find an Arduino, a piezo sensor, a solenoid, and a nine-volt battery. The piezo sensor detects your knocking as an input. It can even listen to and repeat back a series of your knocks. The Arduino actuates the solenoid, which strikes the wooden enclosure, producing the knocking sound.
We’ve embedded a video of this useless machine after the break (that’s where all the puns are). One note for your own build; this box is made out of mahogany and because it is used as a resonance chamber, this may not work as well if it isn’t milled from a piece of quality lumber.
