Floppy Autoloader Takes The Pain Out Of Archiving 5000 Amiga Disks

floppy-autoloader

Archiving data from old floppy disks can be a tedious process at best. Poorly labeled disks combined with slow transfer speeds put it high on the list of things we would rather not do, and it turns out that [Dweller] was of the same opinion. With an estimated 5,000 floppies in his collection, he finally decided it was time to clean house.

With no idea of what was stored where, he decided the best way to go about the process was to read all of the disks, archiving everything, saving the sorting process for later. He originally started by building a floppy autoloader out of Lego Mindstorm parts, which looked good on paper, but performed pretty poorly.

He came across an old floppy duplicator on eBay and figured that since the machine was built for handling gobs of disks, that it was the perfect base for his autoloader. He pulled the mechanical bits from the machine, incorporating them into the rig you see above. He swapped out the duplicator’s brains for an Arduino, which allows him to batch copy his disks and save a picture of each label with little effort.

He says that the system works great, making his life a lot easier (and less cluttered!)

Check out the video below to see his floppy autoloader in action.

Rain Barrel Irrigation System Keeps Your Plants Fed When You’re Too Busy

sprinkler-controler

[Kyle Gabriel] moved into a house with a nice tract of land behind it, but due to his busy schedule he had yet to plant the garden he so desperately wanted. He worried that his hectic life and busy hours would lead to accidentally neglecting his garden, so he built a water collection and automated irrigation system to ensure that his plants never went without fresh water.

The system is fed by two large 55 gallon barrels that collect rain from his gutters. A 1/2 HP well pump is used to pressurize the collected water, which is then dispensed throughout his garden by a sprinkler. [Kyle’s] system is run from a small control box where an Arduino is used to control the pump’s schedule. At a predefined time, the Arduino turns the pump on, while monitoring the system for potential problems.

If the system starts running low on water, the Arduino triggers the valve on his spigot to open, keeping the water level above the pump inlet pipe. He also keeps an eye on pump’s outlet pressure, indefinitely disabling it before a blockage causes the pump to cycle repeatedly.

He says that the sprinkler system works quite well, and with his modular design, he can add all sorts of additional functionality in the future.

Collecting Radon Data In The Name Of Science And Safety

radon-data-collector

When [Chris Nafis] built an addition onto his historical home he found that a Radon problem, previously mitigated with plenty of concrete, seemed to rear its ugly head yet again. He eventually resigned himself to installing a Radon fan and detector – the latter of which offered no way to store measurement data. He wanted to get a better feel for the short and long-term Radon measurements in his house, in hopes of finding some correlation between temperature, moisture levels, and the total amount of Radon emitted from the ground.

To do this, he disassembled a pair of Radon detectors located in different parts of his house, each of which he wired up to an Arduino. Using his oscilloscope to determine which PCB leads controlled the different LED segments on the displays, he quickly had the Arduinos scraping measurement data from the sensors. [Chris] figured the best way to keep track of his data was to do it online, so he interfaced the microcontrollers with Pachube, where he can easily analyze his historical readings.

An additional goal he set for himself is to trigger the Radon fan only when levels start rising in order to save a little on his electric bill. With his data logging operation in full swing, we think it should be a easy task to accomplish.

[Aaron] Shows Us What Life Would Be Like If [Bob Vila] Started Hacking Headphones

[Aaron Horeth] had a pair of headphones that had seen better days, and before he tossed them out, he realized that he could use them to build a set of custom cans. He had always wanted a pair of headphones with a detachable cord to prevent damage when tripped over, and thought that his old set would be the perfect donor.

He swung by his local hardware store to peruse their collection of construction earmuffs, eventually finding a set that looked decent and didn’t cost an arm and a leg. Using construction earmuffs as the framework for his headphones gave him the durability he was looking for with the added bonus of being designed to deaden extraneous noise. Once he got them home he pulled the drivers from his old set of headphones installing them into the earmuffs, but not before he wired them up to support a breakaway input cable.

There’s no doubt that the modifications are simple, but we imagine they come in pretty handy when tinkering around the shop.

Re-live 1978 In All Its Glory With The [Roth] Scream Box

roth-scream-box

We never imagined that [David Lee Roth] would mesh well with an Arduino, that is until Flickr user [tgtsfkncld] showed off his [Roth] Scream Box a few days ago.

The unassuming box resembles sort of a nondescript “Easy Button”, but its payload is far more entertaining than whatever Staples could have possibly recorded for their device. Once the Scream Box is powered on, each press of the button rewards the user with a short sound clip of [Roth] singing the lyrics from [Van Halen’s] “Runnin’ With the Devil”.

[tgtsfkncld] took snippets of the isolated vocal track from the song, playing them back using an Arduino along with an Adafruit Wave Shield. The circuitry behind the device is not overly complicated, though the final result is great. With the wide array of isolated vocals floating around online, it would be very easy to create one for your favorite band/singer as well.

Electric Poncho Keeps You Warm On The Go

electric-poncho

With the mild winter and spring we have had, it might seem strange to think about ways to keep yourself warm, but there’s no better time than the present to prepare for chilly weather down the line.

In his blog [Berto] was thinking about how to keep warm when things cool off again, and decided that a heated poncho would be great to have on hand. He found a dead simple way to craft his heated poncho, requiring little more than a bit of wiring, some thread and cloth, as well as a pair of scissors.

[Berto] picked up a 12V-powered electric blanked, then proceeded to cut a head-sized slit in the middle of it, avoiding the heating coils. He sewed a bit of cloth around the hole to ensure it didn’t end up ripping over time, then he wired the blanket up to a 12V battery he tucked away in his backpack.

The result is a variable-temp poncho that you can use to keep warm in a variety of situations. [Alan Parekh] from Hacked Gadgets says that he thinks the poncho would be awesome on a full-day snowmobiling trip, and we think he’s right!
