Home is absolutely everything these days. Plenty of spaces around the abode have had to do double and triple duty as we navigate work, play, and everything in between. Although it’s been a great time to engage in hobbies and even find new ones, where exactly are we supposed put all the stuff that accumulates?
[Fabse89] needed a portable, usable solution for doing electronics work that could be easily packed away. They happened upon a tool case being thrown out, and repurposed it into a great one-stop solution for whenever the urge to play with pixies strikes.
[Fabse89] started by stripping the box out to the bare walls and modeling the inside in Fusion360. Then they built and cut an acrylic insert that holds two power supplies and a soldering station. There are fixed 5 V and 12 V outputs on one power supply, plus a variable supply that maxes out at 48 V.
When it came to tool storage options, [Fabse89] got lucky with a small, seldom-used set of plastic drawers that fits perfectly next to the power station. These hold all the small tools like flush cutters, pliers, and a de-soldering pump. The top section of the case folds back and is the perfect place for component storage boxes. We think this is a tidy solution and especially like that you don’t have to dismantle it to use it — can be used with everything in place and packed up quickly. We also like that the front lid pulls down into a makeshift table, so this really could go anywhere with mains power.
Acrylic not rugged enough for your tastes? Here’s a DIY supply that doubles as a melee weapon.
Think you’ve seen the best component storage system? This system could only be better if you could walk up and talk to it. [APTechnologies] was tired of using a hodgepodge of drawers and boxen for storing their components. What they needed was an all-purpose solution for storing all kinds of small-to-medium-sized goodies, be they through hole or SMT.
This one happens to have a software interface as well that is searchable with short, crisp expressions that find parts by ID or with parameters. It’s a Python 3 script running on a Raspberry Pi 4B that’s hiding behind the HDMI display. [APTechnologies] printed a special arm for that, and you can find all the files on GitHub. Not only does the LED above the corresponding drawer light up, it lights up in a color that represents the inventory levels. We assume green/yellow/red, but [APTechnologies] doesn’t specify.
Don’t know what to do with some of your components? If they’re really old, they may be no good anymore. It just depends.
I have storage on the mind, and it comes from two facts in my life:
First, I have tons of stuff in my workshop, far too much for the amount of space I have. A lot of this material is much easier to use if it’s well-organized. Think electronics, robotics, building sets. Modular parts that need to go together a certain way for them to be useful. It is imperative, therefore, that I come up with some sort of organization system to keep the chaos in check.
Second, my favorite tool is the laser cutter, born from my love for building vector designs. I can do art on the computer and have it manufactured in front of my eyes, and share my designs with someone else who can remix it into something even cooler.
So with those two facts in mind, I set about creating a modular storage system in Inkscape and cutting out the design from pine boards using a laser cutter. Let us go on a journey through my thought process:

Yes, dogfighting with RC planes is cool. You know what’s even cooler? RC jousting. Considering these eight foot long planes are probably made of foam board or Depron, they’ll probably hold up for a fairly long time. The perfect application of RC FPV.
Home automation is the next big thing, apparently, but it’s been around for much longer than iPhones and Bluetooth controllable outlets and smart thermostats. Here’s a home automation system from 1985. Monochrome CRT display panel (with an awesome infrared touch screen setup), a rat’s nest of wiring, and a floor plan drawn in ASCII characters. It’s also Y2K compliant.
Here’s an idea for mobile component storage: bags. Instead of tackle and tool boxes for moving resistors and other components around, [Darcy] is using custom bags made from polyethylene sheets, folded and sealed with an impulse sealer. It’s not ESD safe, but accidentally zapping a LED with an ESD would be impressive.
Need a stepper motor test circuit? Easy, just grab one of those Polulu motor drivers, an ATtiny85, wire it up, and you’re done. Of course then you’re troubled with people on the Internet saying you could have done it with a 555 timer. This one is for them. It’s a 555, some wire, and some solder. Could have done it with discrete transistors, though.
Someone figured out Lego Minifigs can hold iDevice charge cables. +1 for the 1980s spaceman.
Remember that “electronic, color sensing, multicolor pen” idea that went around the Internet a year or so ago? It’s soon to be a Kickstarter, and man, is this thing full of fail. They’re putting an ARM 9 CPU in a pen. A pen with a diameter of 15mm. Does anyone know if an ARM 9 is made in that small of a package? We’ll have a full, “this is a totally unrealistic Kickstarter and you’re all sheep for backing it” post when it finally launches. Also, this.
Who doesn’t have issues with component storage (seriously, tell us your secret in the comments)? IF you can get your spare parts organized, it’s still quite difficult to figure out where you actually squirreled them away. Labeling drawers is one thing, but what if you have hundreds or thousands of drawers (we’re looking at you, every Hackerspace that’s been around for more than a few months). This project adds a digital cue to well-organized parts storage by lighting up the component drawer for stock selected from your computerized inventory (translated).
The idea is that all of your parts are assigned a drawer space on the computer. When you go into the index and select a part, the assigned drawer is illuminated by an LED. The setup here is a breakout board for an I2C LED driver which interfaces with a Raspberry Pi, but the concept should be easy to implement with just about any system.
Need help getting to the point where you’re organized enough to implement this? So do we. Maybe revisiting this storage roundup will help.
We’re sure everyone could use some more storage and organization in their workshop. [Nixie] is no exception, though he also hates sacrificing tabletop space for boxes. His solution was to attach them to the wall directly by hacking together some brackets. This hack allowed him to hang everything without using internal screws which were a pain to get at if he need to removed the boxes from the wall to take with him.
[Nixie] started by laser-cutting a negative pattern for a mounting bracket that would fit the dovetail rails already on the sides of the boxes. He then pressed a piece of polymorph into this mold, slid the bracket along the side of the box…and realized it wouldn’t work. The piece wiggled around too much because it did not sit firmly in the rail. Back at the drawing board, [Nixie] split the project into two steps. He cast the screw-hole portion of the bracket in its own separate mold, then cast the railing part of the bracket directly in the dovetail section of the box, providing him a much higher degree of accuracy. After joining the two pieces, [Nixie] had a sturdy support bracket that he duplicated and attached around the rest of the bins.
Finally the 13-year-old on Battlefield 3 will get their comeuppance
[Shawn] sent in his fully adjustable auto-fire mod for an XBox360 controller. It’s pretty simple – just an ATtiny85 soldered to a button with a pot to adjust the rate and switch to turn it on and off. It could have been done with a 555, but this is good enough.
Now one for the PS3 bronies
[Capt-Nemo] loves and tolerates everyone so he modded his 60 Gig PS3 with a bunch of LEDs to display Rainbow Dash’s cutie mark. Yes, it’s from My Little Pony. Don’t judge us. Watch the demo video instead.
How do you organize resistors?
A while ago we saw a neat way to store resistors in a piece of foam with a grid according to the first and third color bands. [Greg] did it another way that just puts a label on a piece of foam. Can you think of a better way?
It’s not a synthesizer, but is it fake?
A lot of people have been sending in this video of [Stephen] turning his kitchen into a synthesizer. We’re thinking he turned a bunch of bowls and cans into an MPC / MIDI controller at best, or it was all done in post. We’ll let our readers duke it out in the comments.
Blinky things spinning very fast
A gracious Hack a Day reader sent in a mechanical television demo he found during late night intertube browsing. We know it’s from a 1992 episode of Computer Club that aired in Germany. It’s four rotating bars of 232 LEDs that will display a standard TV signal. We think it might be time for an RGB LED version of this. Any takers?
