Almost every component of this beauty is wood, including the mounting plate and those thicc and lovely keycaps — their top layer is solid oak, and the bottom bit is birch plywood. In order to interface the ‘caps with the switches, [Tauno Erik] designed and printed connector pieces that sit inside the extra large keycaps and accept the stems of the key switches.
Speaking of switches, we’re not sure if [Tauno Erik] ended up using Cherry green switches, browns, or a mix of both (that would be interesting), but each one is mounted on a custom PCB along with a diode and a pull-up resistor. You can see more build pictures at [Tauno Erik]’s site, and stick around for a visual tour of the completed build after the break.
We love it when someone takes an idea they’ve seen on Hackaday and runs with it, taking it in a new and different direction. That’s pretty much what we’re here for, after all, and it’s pretty gratifying to see projects like this wooden ribbon microphone come to life.
Now, we’re not completely sure that [Maya Román] was inspired by our coverage of [Frank Olson]’s homage to the RCA Model 44 studio mic rendered in walnut veneer, but we’re going to pat ourselves on the back here anyway. The interesting thing with [Maya]’s build is that she chose completely different materials and design styles for her project. Where [Frank] built as much of his mic from wood as possible, [Maya] was fine with a mixed media approach — CNC-milled plywood for the case and stand, laser-cut acrylic for the ribbon motor frame, and 3D-printed pieces here and there as needed. The woven brass cloth used as a windscreen is a nice detail; while the whole thing looks — and sounds — great, we think it would be even better with a coat of dark stain to contrast against the brass, as well as a nice glossy coat of polyurethane.
The video below shows the whole design and build process, which was a final project for [Maya]’s audio production class this semester at college. Here’s hoping that it got as good a grade as we would give it.
Bowling is great and all, but the unpredictability of that little ball jump in Skee-Ball is so much more exciting. You can play it straight, or spend a bunch of time perfecting the 100-point shot. And unlike bowling, there’s nothing to reset, because gravity gives you the balls back.
At the bottom of each cylinder is an arcade machine coin door switch with a long wire actuator. These had to be mounted so they’re close enough to the hole, but out of the way of the balls.
Each switch is wired up to an Arduino Mega along with four large 7-segments for the score, and a giant 7-segment to show the number of balls played. Whenever the game is reset, a servo drops a door to release the balls, just like a commercial machine.
The arcade switches work pretty well, especially once he bent the wire into hook shape to cover more area. But they do fail once in a while, maybe because the targets are full-size, but the balls are half regulation size. For the next one, [gcall1979] is planning to use IR break-beam targets which ought to work with any size ball. If you prefer bowling, you won’t strike out with break-beam targets there, either.
Heading off to college comes with its own set of challenges. Harder course material, living away from home for the first time, and dealing with roommates are common hurdles to overcome, but an oft-overlooked issue is the poor quality dorm room desks. For a place that a student is expected to spend a majority of their study time, colleges and universities don’t often provide inspiring areas in the dorm rooms for this task. With a few tools and some time, though, anyone suffering in a dorm can have a much better place to work.
This desk build comes to us from reddit user [lucas_talbert] and is noteworthy for using simple tools and materials to transform the standard, boring desk in a way which won’t upset the facilities manager in charge of the dorm furniture. The backer is a piece of plywood which was covered in bamboo flooring. It was screwed into the back of the desk and secured with L-brackets. A piece of 1×4 was attached around the edges to help hide the LED lights and cables as well.
We like this build for its impressive transformation of an otherwise drab dorm room into a place that most of us wouldn’t mind having as our main workstation, even beyond college. It also uses common materials and is easily removable, both of which are perks when living as a student. The one thing it doesn’t have, though, is the ability to exercise when using it.
Most hobbies come with a lot of tools, and thread injecting is no different. Quilting itself may be Queen Hobby when it comes to the sheer volume of things you can buy: specialized templates, clips, thimbles, disappearing ink pens, and so on. And of course, you want it all within arm’s reach while sitting at the machine.
Years ago, [KevsWoodworks] built an impressive custom quilting desk for his wife. He’d added on to it over the years, but it was time for a bigger one. This beautiful beast has 21 drawers and 6 large cubbyholes for plastic bins. At the wife’s request, one of the drawers is vertical. [Kev] doesn’t say what she put in there, but if it were our desk, that’s where we’d stash all our large plastic rulers that need to be kept flat (or vertical). There’s also a lift, so any sewing machine can be brought up flush with the enormous top.
Fortunately for us, [Kev] likes to teach. He documented the build in a series of videos that go nicely with his CAD drawings, which are available for download. Thread your way past the break to see those videos.
Want to do some thread injecting, but don’t want to spend hundreds on a machine? We got lucky with our entry-level injector. If yours is a piece of scrap or has limited stitch options, replace the motor, or add an Arduino.
We’ve seen plenty of plywood 3D printers before; after all, many early hobbyist machines were made from laser-cut plywood. But this plywood 3D-printer isn’t made from plywood – it prints plywood. Well, sort of.
Yes, we know – that’s not plywood the printer is using, but rather particleboard, the same material that fills the flatpack warehouse of every IKEA store. And calling it a printer is a bit of a stretch, too. This creation, by [Shane Whigton] and his Formlabs Hackathon team, is more of a hybrid additive-subtractive CNC machine. A gantry-mounted router carves each layer of the print from a fresh square of material – which could just as easily be plywood as particleboard. Once a layer is cut, the gantry applies glue to it, puts a fresh sheet of material on top, and clamps it down tight. The router then carves the next layer, and so on up the stack. The layer height is limited to the thickness of the material – a nominal 3/4″ (19 mm) in this case – and there’s a remarkable amount of waste, but that’s not really the point. Check out the printer in action and the resulting giant Benchy in the video below.
Lamps are useful things, and can be a great way to add style and lighting options to a room. Where overhead lights have to provide enough illumination for all manner of tasks, a subtle table lamp can add a nice moody glow to a room when it’s time to kick back and relax. Oftentimes, a stylish lamp can be let down by having a run of the mill plastic switch hanging off the power lead, but it doesn’t always have to be the case. [Emiel] designed this hexagonal lamp with a hidden switch, which works remarkably well.
[Emiel] starts by laying out hexagonal paper templates on plywood and perspex sheet. The plywood is cut on the bandsaw, while the interior cuts on the perspex are made on a scroll saw to avoid unsightly cut entry lines. The outer half of the lamp slides up and down on a pair of steel rods. Springs hold the outer half up, and it can be pressed down to activate a switch inside to turn the lamp on and off.
