Portable Workbench Crams An Entire Workspace Into One Box

Posted on by

Making on the go is sometimes required in today’s busy lives, and if you find yourself traveling — say, off to university like [ZSNRA] — then a convenient solution is required. To that end, a portable electronics workbench was built in the shape of a relatively nondescript plywood box.

Plywood and foam-core are the main materials used in building this maker’s bug-out box, with two fir runners along the bottom so the case is not resting on the hinges. Inside, [ZSNRA] has packed a staggering amount of hardware which results in an 11kg suitcase.

Here goes — deep breath now: …read more

Hacklet 125 – DIY Laptops

Posted on by

In the old days of the 1970’s, the only way to get your own computer was to build one from scratch. Thanks to an army of hackers like [Woz], PC’s are no commodity objects that can be bought for a couple of hundred dollars. The magic of building your own still is there though – especially when we’re talking about portable machines. Laptops, notebooks, netbooks take quite a bit of skill to assemble. Stuffing a keyboard, screen, and battery into a small clamshell case takes a bit of planning. Our last look at DIY laptops was exactly 100 Hacklets ago, …read more

How To Make Your Weller Wireless

Posted on by

On occasion I have encountered portable soldering irons and my impressions of them have ranged from nearly usable to total rubbish. While using a popular butane powered model and pondering if it was really any better than a copper wire and a candle a thought occurred to me. A regular old Weller station runs on 24 volts AC and performs all of its temperature regulation in a magnetically activated thermostatic fashion and all of that goodness occurs within the hand piece itself. It stood to reason that it could perform just as well with a DC source.

In this instance …read more

Hackaday Prize Entry: Helping Millions See Clearly

Slit lamps are prohibitively expensive in the third world areas of India where they are most needed. An invention that’s been around for over a hundred years, the slit lamp is a simple-in-concept way to see and diagnose a large array of ocular issues.

Since they are relatively old by technological standards, the principles behind them have become more and more understood as time has gone on. While a nice lab version with a corneal microscope is certainly better, innovations in manufacturing have brought the theoretical minimum cost of the device way down, or at least that’s what [Kewal Chand …read more

Incredible Luminosity in a Portable Package

Posted on by

If you’ve ever wanted to bring the brightest day into the blackest night, this flashlight shall give you sight. With a 100W LED array powered by up to 32V, this thing is exceedingly bright — it clocks in at about 9000 lumens! But the best part is that all every little detail of the build was documented along the way so that we can tag along for the ride.

The all-aluminium case houses the LEDs and their heat sink, voltage regulator and display, the AD and DC adapter and converter boards and their connectors, and fans to ensure adequate ventilation. …read more
