It is amazing what you can accomplish with a web cam, cheap laser pointer and a bit of C++ coding. The complete build, along with all the source code, is available on the site.
There are many off the shelf range finding components available including ultrasonic, infrared, and even laser rangefinders. All of these devices work well, but in the field of aerial robotics, weight is a primary concern. It is desirable to get as much functionality out of each component that is added to an airframe. This page describes how a mini laser pointer can be configured along with a single camera to provide mono-machine vision with range information. [via]

Warny shows how to make a wireless remote for a Minolta 5D – “I wanted to buy a remote for my new minolta 5d… After a short search on ebay i found that wire remote were almost 25€ (~30$) and that there were no wireless. First, i tried to contact the remote connector’s outlets. One was neutral, one was for focus, and the last one triggers the picture. So i decided to build one on my own, and that’s not that difficult. Plus, it brings a new function to my camera : a A mode.” [via]

USB-LED-Fader can control up to 8 LEDs with individual brightness waveforms. Its command line tool can easily be integrated into scripts to implement a status display for computer load, mailbox status, network load, video recording software or similar background tasks.

The FT8U232AM based USB to RS232 converter requires a small number of external components to produce a device that converts USB to TTL level RS232 signals. All you need to add is a TTL to RS232 converter to provide the 12V RS232 logic levels.

Turns out that a Ping Pong ball makes a reasonable LED diffuser. Just drill a hole and insert the LED. Easy micro Locnar! With an RBG LED this could make a nice system indicator. Maybe build a strip of these indicators to make several status indicators. Each server gets a mini orb to show it’s online status, maybe each email account. How about a ball of balls, each with an RGB LED… [via]

This is a USB to UART board that allows easy reprogramming of the LilyPad main board without the need for soldering. This board is based on the FT232RL IC from FTDI.
- Implements full v2.0 USB protocol
- Needs no external crystal
- Internal EEPROM for device ID and Product Description strings
- Royalty-Free Driver support for Windows, Linux, and Mac OS X

It seems like MAKE is fond of arduino projects, so here is my contribution. Here is 4 cheap $1 displays mounted in a picture frame and hooked to and arduino. Using just 6 pins, I am able to individually control 552 leds. I wrote a bit of code to write a series of messages to the displays. This code listens for serial data to update the displays. Any text can be shown, but I am currently using a perl script to send the weather forecast from google to it. [via]

I love looking inside chips, and Flylogic takes some of the sweetest chip shots. bushing sent me some Wii chips to play with a few weeks ago, and Chris at Flylogic expertly decap’d and imaged them for me. I thought they were pretty neat, so here’s a couple of them to share with you… [via]
