• Motorcycle current gear indicator
  [Vassilis Papanikolaou] just finished building a gear indicator for a motorcycle. This quite a simple implementation compared to some of the other vehicle information displays we’ve taken a look at. You should be able to build and install your own without breaking the bank. An ATtiny25 microcontroller reads data from a couple of hall effect sensors [...]
• 1000W induction heater
  [Tim Williams] likes to heat things up with this induction heater he built. At peak it can use 1000W and as you can see in the video, that’s more than enough power to heat, burn, and melt a plethora of different objects. The case design uses a center divider to isolate switching noise from the [...]

• USBasp: AVR programmer based on ATmega8
  We love our AVR Dragon programmer but it can be nice to have a cheap and simple in system programmer on hand too. The USBasp is one such programmer that uses and ATmega8 as its only IC. It requires just a handful of components and can be purchased as a kit, or etched and assembled [...]
• Nixie-display brings more wiring madness
  [Tim Anderson] whipped up this nixie tube display using epoxy-coated wires. He’s certainly giving the wire-wrapped LED display a run for its money. He ground the epoxy off the end of each wire using a Dremel before soldering them. We thought you could solder right through the epoxy but maybe not. Was this easier than [...]

• HID crafting with a PIC and a joystick
  [Amr Bekhit] converted his gameport joystick to use as a USB joystick. Much like a universal USB joystick interface, this uses an additional microcontroller to talk to the serial bus while monitoring the controls on the stick. [Amr's] discussion about creating HID descriptors is clear and easy to understand. What he’s laid out can be [...]
• Easy data input for LabVIEW
  Props go to [Michael Nash] for establishing an interface between National Instrument’s labVIEW and an Arduino (an example video using a potentiometer is above). Personally, from the one time we were forced to use labVIEW, we hated every second of it. One reason it’s so terrible, is the Data Acquisition Modules cost well into the [...]

• Modern recordings on wax cylinder
  If you thought you’d never have a chance to release your hit single on the wax cylinder think again. A band obsessed with the Victorian era did just that, having a DIY’er produce the cylinders for them. The story was covered by the BBC and includes a lousy attempt to build a phonograph to play [...]
• Stomp box synthesizer
  [Brian McNamara] fed the output of his guitar pedal back into its input creating a looped synthesizer. He started with an effects pedal he made but now we think he’s ended up with an electronic stomp box. Check out the results in the video after the break. Now he needs to make the knobs foot-friendly so [...]

• May the Phorse be with you
  The PhorsePOV by [Julian Skidmore] almost slipped by, but we thought it was a nice easy hack for your Memorial Monday. The gadget uses an ATTINY25 to drive 6 LEDs aren’t standard characters 7 units high? Which when waved in the air produces a readable message. What we were really interested in is the use [...]
• Beginner Concepts: Cascading shift registers
  There’s a million tutorials out there describing how to use shift registers. If you’re just getting into embedded systems you should know how to use them as they allow you to take three microcontroller pins and expand them virtually without limits. This is due to the serial-in parallel-out nature of these integrated circuits. A key [...]

• Child-sized cocktail cabinets
  [Sam Seide] dropped us a line about his new arcade creation. We loved his Punch-Out build that used a punch dummy as a game controller. This time around he’s made some mini-cocktail style MAME cabinets. He removed the screen from a netbook and placed it face-up underneath the acrylic bezel. There are controls on either [...]
• Crossfade curve tweaking
  Tired of the disappointing performance from the crossfader on his Numark MIXDECK, [dj JD] cracked it open and made the crossfade curves adjustable. It’s a super-simple hack that just introduces two 100k trimpots to the crossfade slider. The change led to a higher volume level on the current channel until the slider was much nearer [...]

• SPRIME controlled AC outlets
  Reader [Tim Upthegrove] sent in a novel take on powering and monitoring AC outlets and devices called SPRIME, or Simple Powerline Remote Interactive Monitor and Enforcer. Compared to previous hacks, such as 120v switching or Quick cheap remote outlets, that only turned an outlet on or off; SPRIME allows not only control over outlets via [...]
• Hoverboard comes to life
  This installation by artist [Nils Goudagnin] is a recreation of the hoverboard from Back to the Future II. We would like to see inside that plinth. We’ve seen levitating magnets before, but this is particularly stable. He says he is using lasers and a control system of some kind to stabilize it. Just to guess, [...]

You can get the game Slay for free temporarily HERE. The game is also available for Windows and PocketPC, of which more details are available on the official website.

“Slay is a simple to learn game of strategy and cunning set in medieval times. The island is divided up between the six players, and you must try to capture your enemies’ land and link up your own territories to create larger and stronger ones. You begin capturing land by attacking with your peasants. Once your territories become richer you can combine peasants to make stronger and stronger people (Spearmen, Knights and then Barons) who can kill weaker enemy troops, or knock down their castles. Just be careful that you don’t create too many expensive men or the territory will go bankrupt! ” – Slay Website

• Home DNA lab tools
  [Jeri Ellsworth] stopped by Pearl Biotech’s booth at Maker Faire and took a look at their open source DNA sequencing work. It is by no means a grab-and-go solution for anyone, but from what we’ve seen in the video they’re breaking down those laboratory walls and letting us in to dabble at this work (assuming [...]
• 2010 sees new lock impressioning speed record
  [Jos Weyers] tipping us off about this lock impressioning video. It shows his final round of the lock impressioning championship at this year’s SSDev conference. Even though he shaved about fifteen seconds off of his 87-second single-lock record from last year he came in third overall because the competition averages times over several rounds. This [...]

• Adding SCART to a cheap CRT television
  [133MHz] cracked open a cheap tube television to add a SCART connector. He knew he had a chance at success when he discovered all of the knock-outs on the back of the connector panel because one of them was exactly the right size for the connector. But it wasn’t quite as easy as soldering in [...]
• Commercial webcam multi-touch coming soon
  It looks like Toshiba has a webcam-based multi-touch display on the way. The video shows an iPod-esque photos album interface where the user stands in front of the display and manipulates it with both hands. The difference between this and some of the other multi-touch displays we’ve seen is that there is no touching necessary [...]
