If you’ve got an old mouse sitting around that has that perfect retro look why not start using it again? We’d bet there’s just enough room in there to turn the input device wireless.
The hack does away with everything but the case. The guts from a brand new wireless laser mouse are used as replacements. For the most part this is a simple process of making room for the new board and laying it in place. It involves cutting off a few plastic case nubs, enlarging the hole on the bottom so that the laser has a clear line of sight to the desktop, and hot gluing the thing in place. The button cover had a bit of plastic glued in place so that it lines up correctly with the replacement mouse’s switch.
The only thing that didn’t work out well is the battery situation. The AA cell that the mouse needs was too big for the retrofit so it was swapped with an AAA. These have a lower capacity which means more frequent replacement.
[Paul] spent his summer bringing an iMac G3 into this decade. There’s plenty of room to work with since he removed the CRT which originally occupied most of the computer’s space. The final project is much more powerful and since he preserved most of the metal mounting parts inside it remains quite strong.
He started by swapping flat screen monitors with his Grandma (who incidentally runs Linux… nice!). She had a 15″ model which would fit nicely in the case so he upgraded her to 17″ and took the old one. With bezel removed it fits perfectly where to old tube had been. Next comes the power supply. It’s mounted on the bracket which held the back of the tube, with a bit of metal removed to clear the air intake. To mount the motherboard he fabricated a bracket at one end where the iMac’s stage drops away. In retrospect he wishes he had rotated the board to make the I/O panel more accessible. The hard drive mounts on the original carriage, and he did some creative gluing to make his replacement DVD drive align with the original optical drive opening. The finished product looks great from the front and sides, with the cables running out the back as the only indication that it’s had some major work done on it.
If you don’t have the patience to play through the original Prince of Persia perhaps you should just cheat? [BLuRry] has made this easy for us, by building Prince of Persia cheats into JACE, the Java Apple Computer Emulator.
He shows off the emulator and the cheats he added in the video after the break. We saw the ability to teleport anywhere, kill enemies immediately, and open gates and exits. All of this happens with the click of a mouse. But there’s also a configuration screen used to enable the cheats that offers a handful of other cheat options that weren’t original to the game. [BLuRry] managed to roll these cheats into the emulator after some thoughtful study of the original source code which [Jordan Mechner] recently released after the once-lost floppy discs storing the ancient digital gem were discovered.
You know, we always see people running doom on various types of hardware. Maybe we should start using PoP as our go-to novelty game?

Over on the 68kmla forums, a website dedicated to old Macs built before 1994, [zydeco] released his Android port of Mini vMac, a Macintosh Plus emulator that puts the power of a Motorola MC68000 processor and System 7 on any computer.
Unlike the original Macintosh, or the subsequent revision that bumped the RAM up to 512 kilobytes, the Mac Plus was actually useful. With the addition of a SCSI port and support for 4 Megabytes of RAM, it’s not only possible to browse the Internet, but also act as a server. There’s a reason [Sprite_tm] chose to rebuild one of these classic, all-in-one machines to act as a home server; they really do epitomize the elegant computers from a more civilized age.
68kmla user [FlyingToaster] even went so far as to put a Mac Plus in his nook touch. With this, he’s got a full-blown installation of System 7 running on an e-ink screen, complete with Lemmings, Gauntlet, and Tetris.
It should be possible to plug this emulated box into the Internet. Unfortunately, experience tells us it won’t be a very pleasant browsing experience outside Hackaday’s retro edition.
[Professor Shadoko’s] Mac Mini died. But since the case designs on Apple products are half the reason to buy them, he decided to reuse the enclosure by turning it into this clock (translated).
As with the binary clock we saw yesterday, this one uses a bunch of LEDs to display the time, but it does it in a way that’s a bit more readable if you know what you’re looking for. The face has been divided up into two columns. On the left is hours, then minutes and seconds in increments of five. To the right is AM/PM, with minutes and seconds in increments of one. If we’re doing this right, the time seen above is 10:23:42 PM on April 28th, 2012. The white LEDs below the date act as a digital pendulum, scrolling left and right as the seconds tick by.
The display uses two MAX7219 LED drivers to control the grid which is build on a big hunk of protoboard. An Arduino ties the whole system together with a Chonodot for accurate time keeping. There’s even an ambient light sensor which adjusts the LED intensity to make this readable in direct sun, or the dark of night. See a demo clip embedded after the break.

There’s a word – synchronicity – to describe two disparate events that occur together in a meaningful way. We see this a lot in the Hackaday tip line; two people send in somewhat similar hacks solving similar problems in similar ways nearly simultaneously. Here’s two builds by [Bryce] and [spektakx] that hit our inbox within minutes of each other that both implement existing interfaces with iPads.
iPad turntable controller
[spektakx] sent in an iPad powered DJ MIDI controller he built as a prototype to test out the size, orientation and layout for an upcoming build. The turntable controllers are simple USB affairs made to jog and scratch records digitally. Although [spektakx] admits it’s a little unfinished, it’s still just a prototype. Also, he can use a Windows 7 tablet laptop for ‘more suited’ hardware. Check out [spektakx]’ video demo after the break.
an iPad cash register
[Hacktheory] found [Bryce]’s Flickr photolog of a DIY ‘Square’ cash register. The electronics part of this build is practically non-existent; it’s just an iPad with a credit card readers that plugs into the headphone jack. Yes, we just saw these ‘Square’ credit card readers this last week. The fabrication portion of this build is incredible – [Bryce] has a few wonderful pieces of walnut there, and did an exceptional job with the wood work. It’s probably not well suited to high-volume retail, but we couldn’t think of a better cash register for a boutique shop.

Remember the times before the iPad existed? When a tablet PC was actually a full computer in a tablet form factor? Yeah, those days we were all so very optimistic about the future of tablet computing. Don’t think we don’t appreciate the new amazing toys that we’ve got around with the plethora of tablets to choose from, but we still dream of fully functional tablet computers.
[Brian] wrote in to show us his build of a fully featured tablet macbook conversion dubbed the MessagePad. Though we’ve seen a wide selection of home spun tablets before, this one has an impressive list of added features. It boasts both front and rear facing cameras, an SSD drive, a built in Teensy, and a line-in. It doesn’t matter if you believe in the dream of a full blown pc in tablet format, or if your preference would have been a Windows or Linux machine. You’ll surely love the bevy of photos he took along the way as he was hacking and slashing on this thing.
