Caffenol turns Folgers into DIY film developer — decaf won’t do (video)

Caffenol turns Folgers into DIY film developer -- decaf won't do (video)We knew instant coffee was good for something. The folks at Make just demoed a rather novel method for developing negatives from a roll of black and white film — you remember film, don’t you? Known as Caffenol, the process involves a smattering of household substances, including Vitamin C powder, instant coffee (caffeinated only), good ole H2O, and Cascade. Of course, it’s not as simple as throwing this stuff in a slosh bucket with a roll of film and mixing it up, but it’s not that complicated, either. If you’re looking for something to do with those instant crystals, and still have a non-digital camera laying around, hop on past the break for a homebrew tutorial.

Modder outfits Nexus One with an Arduino-powered, pager-style display — of course

Not satisfied with a Sony Ericsson LiveView as a secondary display for your Android phone, or a dual-screen device like the Kyocera Echo? Then you might want to consider something like this decidedly more homebrew approach from modder “follower,” which uses the Android Open Accessory protocol to connect the Frankenpager-type contraption you see above to an otherwise ordinary Nexus One. Of course, that two-line display does limit things somewhat, but it will at least let you see the time and any incoming text messages without forcing you to leave your game. Hit the source link below for all the details and software you need to build your own.

AMD Llano desktop APU gets reviewed: the best integrated graphics in town

AMD is due to release a batch of new Llano APUs next month that are specifically tailored to desktops rather than laptops. The most powerful among them will be the 2.9GHz A8-3850, which has already caused a stir on the review circuit for one simple reason: it pulls off a brutal “one shot one kill” on Intel’s HD 3000 integrated graphics. AnandTech raised an impressed eyebrow at the fact that all its benchmarking games were playable on the $135 AMD chip, which roughly doubled frame rates in titles like Modern Warfare 2, Bioshock 2 and World of Warcraft compared to the more expensive Sandy Bridge i5 2500K. TechSpot declared the APU its “new budget king,” with graphical performance “on another level” compared even to an i7.

However, the superlatives quickly evaporated once reviewers shifted their focus to the CPU. TechReport spotted that pure CPU performance per dollar was actually lower than what you’d get from a lowly i3. Moreover, it reckoned you’d only have to spend an extra $70 to buy a much more powerful CPU and a separate graphics card — an option that comes “awfully close to making the A8-3850 seem irrelevant.” Ouch. Nevertheless, if an affordable processor with integrated graphics is what you’re after, then it’s fair to say this one sets the standard. Click the source links below for full reviews.

1996 Corvette converted into a 2011 electric odyssey (video)

A supercharged Chevrolet Corvette may have been all the hotness back in 1996, but times and tastes change and now people are all about the electric boogaloo. Today we get to witness one modern man’s transition into this brave new world, a Wayne Bickley from California, who has gutted his crow-black ’96 Corvette and replaced the messy internal combustion setup with a set of 18 XS Power XP1000 batteries, a DC electric motor, and his own clutchless six-speed transmission. The end result doesn’t really look much different, but its 20-mile “spirited driving” range and 85mph top speed will surely feel different and it does also sound very much like something from the future. Check out this modernized Chevy on video after the break.

Game Gear mod has five-inch screen, rechargable batteries, two pounds worth of memories

Are Nintendo and Sony’s portable gaming offerings not doing anything for you? Yearn for the days of Hedgehog-based adventure? You’re not alone — though, unless you’re as crafty as “lovablechevy,” you’re going to have to settle for whatever you can find on eBay or in a dusty shoebox under a bed at your parents’ house. The modder resurrected a Game Gear with a custom case created using the beloved Sega portable, a Master Gear converter, a screen from a PS One, and assorted other bits and pieces. The franken-portable can play Game Gear and Master System titles, has a rechargeable battery, and weighs a hefty two-plus pounds. Video after the break and lots more jealousy-inducing images in the Source link below.

Gigabyte intros Llano-compatible A75 motherboards for the DIY set (video)

Llano-based PCs are still trickling their way into the market, but if you’re the enterprising type you can just up and build your own. Gigabyte just announced a family of seven A75 series of motherboards, all of which are compatible with AMD’s spankin’ new Fusion A6 and A8 chips and A75 chipsets. To recap, the Fusion A-Series combines a discrete-class Radeon HD GPU and either a dual- or quad-core CPU on the same die, though all of the A6 and A8 models are quad-core. These 35- and 45-watt chips are also stereoscopic 3D-capable and support USB 3.0, DirectX11, OpenCL / OpenGL, and both 1600MHz DDR3 memory and lower-power 1333MHz DDR3L memory. As for the motherboards, they allow for 108dB audio with 7.1 surround sound, and you can use Gigabyte’s Easy Tune 6 utility to realize Fusion’s promise of overclocking. They also use the company’s DualBIOS technology to prevent failure due to BIOS corruption, while each USB port has its own fuse to prevent port failure. Hit the source link for information on where to buy, and mosy on past the break for the full PR and a short demo video.

DIY antenna cannon was inspired by potato guns, powered by Android

One of the difficult things about being an amateur radio fan is that you generally have to procure and set up your own gear, and that includes laying your own antenna. Normally, it’s done with pressurized rifles or using a bow and arrow tied to fishing line to get the antenna uncoiled and into the […]

The Acorn A7000+ portable mod is what your MacBook looks like in an alternate universe

Aside from its attempted rebirth as a laptop manufacturer back in 2006, we haven’t heard all that much from Acorn Computers in the past, oh, two decades or so. And if you’re not a UK native, there’s a pretty good chance that you didn’t hear all that much about the “British Apple” before then either. But while the company’s more official attempt to go portable was nothing to write home about, its late-period A7000+ desktop has now seen a successful second life at the hands of a British modder as the A7KP. The Acorn’s innards have been stuffed into a five pound (relatively) portable setup, featuring a 10.4-inch LCD, 4GB of flash memory, and a battery that offers up three hours of RISC OS-based fun. It’s enough to make you wonder how you ever played Lemmings on anything else.

Jack Eisenmann’s DUO Adept: a homebrew 8-bit computer built by a high-schooler (video)

We’ve seen some impressive case mods and some wildly inventive DIY projects, but rarely have we seen a homemade, 8-bit computer housed in what looks like a Tupperware container. Meet the DUO Adept: a project begun last summer by programmer, hardware hacker, and recent high-school graduate Jack Eisenmann. Lovingly crafted from a television, an old keyboard, 100 chips (not a single one more), and lots of wire, the system has 64K of memory and outputs a 240 × 208 black and white image. Eisenmann designed his own operating system and even wrote several games, including the Donkey Kong-esque “Get Muffin.” Hit the source link for a gallery (including circuit diagrams!) and see the video below for a demonstration, complete with 8-bit era music.

Web-controlled tweeting Roomba is a perfect storm of DIY magic

Web-controlled tweeting Roomba

There are three things that will guarantee your DIY project some attention: slap it on a Roomba, base it on Arduino, or make it tweet. Do all three and, well, you’ve got a nerdgasm-inducing bit of Make fodder. The creation you see above is a web-controlled tweeting Roomba whipped up by Instructables member matchlighter using a 500 series vacuum bot and the Sparkfun WiFly shield for Arduino. The autonomous cleaner can be triggered from anywhere there’s an internet connection and updates Twitter to keep you abreast of its status (Ahh! Dock sweet dock). While Mr. matchlighter was kind enough provide directions for building your own, a lot of the actual coding is left up to you. (We’re lazy, let us just copy and paste dammit!) If you think you’ve got the programming chops, hit up the source link for instructions and check out the original’s Twitter feed at the more coverage link.

Update: The complete code is in step eight of the Instructable.
