Inductive Charging Going Mainstream

November 3, 2008 by Caleb Kraft 31 Comments

The recent announcement of Psyclone’s TouchCharge kit has us moderately excited. Though inductive charging has been used in electric toothbrushes for ages, we have yet to see it infiltrate the rest of our lives. The kit is a bit pricey at the moment, but it is a step in the right direction. Unfortunately, you have to have an adapter for your specific product and their selection is pretty limited right now. Why not make your own to power your devices? Warning: it is written from the perspective of [Arnold Schwarzanegger].

Update: Is the TouchCharge kit inductive? It appears to require contacts to touch the base.

Rapidfire Wii Mod

AcidMods is at it again. They just can’t bare having to push the fire button over and over on their own. They’ve made a rapid fire mod for the wii. They said the mod wasn’t too difficult as Nintendo labeled everything nicely on the PCB. We like that they have added the back light on the button to tell you that you’re in rapid fire mode.

Wooden Retro Keyboard Build

November 3, 2008 by Caleb Kraft 14 Comments

[phirzcol] sent us this cool step by step build of a retro looking keyboard, Inspired by [Von Slatt] and his work. [phirzcol] starts with a standard keyboard and removes the keys. He steams some wood to wrap the keyboard, then finishes it off nicely. The process of making the keys looks pretty grueling. Each key has 4 parts which have to be hand cut and assembled. A blue accent light is a nice touch as well. The keyboard looks pretty good, but we’d like to try typing on it for a while to see how usable it is. If it looks like too much effort, you can actually buy it on ebay.

Meet Skelly, the propeller powered singing skeleton, winning entry to the Unofficial Propeller Halloween Contest. Sick of the massive amounts of Arduino projects floating around the web, [Oldbitcollector] offered a halloween challenge. Make something spooky using a propeller and other parallax stuff, win a prize. Skelly, made by [Chuck Rice] was the star of the show, so [Chuck] will be getting some USB development boards in the mail.

No Nintendo DSi Homebrew

November 3, 2008 by Eliot 44 Comments

The latest version of the Nintendo DS, the DSi, has officially launched in Japan. It features larger dual touchscreens, dual cameras, and an SD card slot. The members of GBAtemp.net have decided to tackle the most important question: will it run homebrew? Current DS systems just need a purpose built flash cartridge to load homebrew software (usually stored on MicroSD). Forum members have tested at least 10 different flash carts, and none of them worked. While not completely exhaustive it’s proof enough to us that current generation carts will not work. We hope this is something that can patched with a new firmware. Most carts load their firmware off the flash, so upgrades are easy. The blocking of homebrew maybe a side-effect of Nintendo’s announced region-locking on the DSi.

We hope this gets sorted out soon. Maybe we’ll see hackers figure out how to take advantage of the SD slot instead. If you’ve got a Nintendo DS, there’s no excuse not to be playing with homebrew. It’s as easy as copying files to a card. We’ve had success with the DSTT, which you can find on DealExtreme for just $10.

Wireless Arduino Programming With ZigBee

November 2, 2008 by Eliot 18 Comments

ZigBee is a low-power communication system using digital radios. It’s intended to be easier to work with than Bluetooth. Adafruit recently added an adapter board for Digi’s XBee product line and has put together a great how-to to show the devices potential. Using two XBee radios and adapters you can wirelessly program an Arduino board. This would be great if your Arduino was installed in an inaccessible area or maybe it’s over 100feet away from where you’re working. The radios do serial communication just fine. What the how-to covers is getting the reset line working so the Arduino can restart automatically after you program it. Once the radio pair is configured properly, it will pass the RTS line state directly from one device to the other.

Robot Fish CAD Models

November 2, 2008 by Eliot 4 Comments

[Bre] dug up this excellent robot fish prototype project. The PPF-O9 has three servos. One on the forward fins to control depth, one on the middle joint, and one final one drives the tail fin. The battery box is mounted to the underside. The control scheme is interesting: the right stick controls left/right and up/down while the left stick controls the frequency and amplitude of the motion. They say the robot is fairly stable, but swimming and turning can be slow. They’ve included CAD files for almost every component to help you with your own designs.
