Space Invader Button

April 14, 2009 by Eliot 36 Comments

[Marcus] saw [Alex]’s 64 pixel project and decided it could be implemented in even less space. Pictured above is his Space Invader button with a bicolor LED matrix. The controller board is all SMD and piggybacked on the matrix. An ATmega164P drives the 24 pins via transistors. In addition to animation, the board can do LED sensing too. It’s a very clever project and [Marcus] has some notes about working with such tiny components. You can see a video of it below. Continue reading “Space Invader Button” →

Spatialized Umbrella

umbrella-1

Reader [Joe Saavedra] sent in his latest project: the spatialized umbrella. The base of each umbrella rib features an LED, speaker, and distance sensor. These are connected to an ATMega168 microcontroller running the Arduino environment. The IR sensor triggers a rain drop sound based on proximity. Shorter distances mean more droplets are played. The sounds are generated using a lookup table and the digital pins. You can see the demo video embedded below.

Using the Arduino environment without the associated board is part of another idea that [Joe] is working on. The MapDuino Project uses the standard Arduino hardware for programming, but then transfers the chip to a more barebones circuit in target project. They based their initial work on the ITP breadboard Arduino. Continue reading “Spatialized Umbrella” →

Tweenbots Rely On Human Help

tweenbots

[Kacie Kinzer] put together an interesting social experiment: Could a robot navigate purely by the help of strangers? She constructed an inexpensive Tweenbot robot that would drive in a straight line. A flag was attached to the top with a plea for help and a destination. Surprisingly, on the first run it was able to traverse through Washington Square Park in just 42 minutes with the help of 29 people. You can see a video of the first run below. This is part of [Kacie]’s thesis work at ITP and she has many other bots planned. While it’s a great demonstration of human kindness, there’s another lesson: If you don’t think your public project looks innocuous enough, draw a smiley face on it.

HAL Suit Going Into Production

When we compiled our list of real life power suits last May, the HAL suit was being pitched as a $1000 a month rental. Cyberdyne has changed their tune for the better recently. Teports suggest that the first 400 unit run of powered exoskeletons will sell for $4200, less than a Segway. The suit can increase the wearer’s strength ten-fold and will run continuously for nearly three hours.

Dell Adamo Teardown

TechRepublic and iFixit partnered to teardown Dell’s flagship notebook, the Adamo. The Adamo is positioned to compete directly with Apple’s MacBook Air. The Dell crams a lot of technology into a very thin frame and they use a clever locking system for the backplate to hide any screws. The built in battery has a longer life than the Air and an SSD comes stock. The team points out that the Windows logo is etched on the backside instead of the standard ugly stickers; apparently this took quite a bit of teeth-pulling to get approved. Check out the full photo gallery which includes the fetish packaging and comparison shots to the Air and Dell Mini 9.

Nintendo DSi Teardown

Now that the Nintendo DSi has been officially released in the US, the team at iFixit has worked their magic. That magic being: completely disassembling it. They found the new 840mAh battery to be much smaller than the DS Lite’s 1000mAh. The device features two cameras, but both are a paltry 0.3megapixels. They note that this is the first Nintendo device that they’ve taken apart that didn’t require a tri-wing screwdriver.

Many more DSi compatible flash carts are available now than our initial report in December, so you can pick up a Nintendo DSi for homebrew without worry.

Commodore 64 Laptop

[Ben Heck] has just completed one of his more unique laptop game consoles. This time around it’s a Commodore 64, which he’s been attempting since 2006. Recently he scrapped everything and started fresh on what turned out to be the fastest build yet. While it certainly looks similar to his other laptops, he put in a lot of effort to give it the appearance of an 80’s computer from the beige color to the texture. He used an original C64C motherboard since it was the final and smallest revision and coupled that with an original keyboard. A 1541-III-DTV allows use of an SD card as a floppy device. Just drag any disk image onto the card and it’s ready to go. Check out a video of it in use below.
