The Regulatory Side of Rolling Your Own Moderate Solar Farm

[Russell Graves] lives in Idaho and recently connected his solar installation to the grid, which meant adhering to regulatory requirements for both the National Electric Code (NEC) as well as complying with the local power company’s own regulations. His blog post is an interesting look at the whole regulatory process and experience, and is of interest...

Using Heaters to Display Time

We’re always fans of interesting clock builds around here, whether it’s a word clock, marble clock, or in this case a clock using a unique display method. Of course, since this is a build by [Moritz v. Sivers] the display that was chosen for this build was a custom thermochromic display. These displays use heat-sensitive material to change color, and...

Upgrading the PowerBook 100 With A Fresh New Battery

The PowerBook 100 was one of the earliest Apple laptops released, coming not long after the breakout Macintosh Portable. Unlike modern hardware, it relied on sealed lead acid batteries. [360alaska] has such a laptop whose original battery is long dead, so they set about building a replacement battery with lithium cells instead. The battery and its...

A Tidy Octave Mod For The Casio SK-1

1985 saw the release of the Casio SK-1, a compact sampling keyboard that brought the technology to a lower price point than ever before. However, one drawback of this was that it comes stock with only a 2.5 octave keyboard. [Jonas Karlsson] wanted a little more range out of the instrument, so set about hacking in his own octave mod. The build consists...

How To Get Into Cars: Land Speed Racing

Land speed racing is one of the oldest forms of motorsport, and quite literally consists of going very, very fast in (ideally) a straight line. The higher the speed your car can attain, the better! It’s about the pure pursuit of top speed above all else, and building a car to compete is a calling for a dedicated few. If you’d like to join them, here’s...

The Ridiculous GameCube Keyboard Controller Gets Modded

Believe it or not, there was a keyboard peripheral sold for the original GameCube, and it was built into the middle of a controller. Designed for the Phantasy Star Online games, it allowed players to easily communicate with others via chat. [peachewire] got their hands on one, and set about modifying it in the way only a true keyboard fanatic could....

Where Are All The Cheap x86 Single Board PCs?

If we were to think of a retrocomputer, the chances are we might have something from the classic 8-bit days or maybe a game console spring to mind. It’s almost a shock to see mundane desktop PCs of the DOS and Pentium era join them, but those machines now form an important way to play DOS and Windows 95 games which are unsuited to more modern operating...

Is that an EMP Generator in Your Pocket or Is My Calculator Just Broken?

Ah, what fond memories we have of our misspent youth, walking around with a 9,000-volt electromagnetic pulse generator in our Levi’s 501s and zapping all the electronic devices nobody yet carried with them everywhere they went. Crazy days indeed. We’re sure that’s not at all what [Rostislav Persion] had in mind when designing his portable EMP generator;...

Cloned Memory Module Fixes Broken Scopemeter

Finding broken test gear and fixing it up to work again is a time-honored tradition among hackers. If you’re lucky, that eBay buy will end up being DOA because of a popped fuse or a few bad capacitors, and a little work with snips and a soldering iron will earn you a nice piece of test gear and bragging rights to boot. Some repairs, though, are in...

Fit Your LCDs with Lenses for That Vintage CRT Look

For as big, bulky, and power-hungry as they were, CRTs were an analog joy of the early days of TV, video games, and computers. The crackling high-voltage, the occasional whiff of ozone, the whizzing electrons lancing through a vacuum to excite a phosphorescent image — by comparison, thin-film LCDs are sterile and boring. Sadly, CRTs are getting harder...
