An old book – the smell, the texture of the slowly rotting paper, and the smudges and margin notes accrued over decades – is one of the finer points in life taken for granted much too often. We’re bombarded with high precision vector typefaces all day, but [Dan]‘s Avería font is beautiful in its irregularity. [Dan] [...]

[Dan] had been wanting a pair of Bluetooth headphones for quite a while. Most of the reviews for wireless headphones in the $50-$80 range complained of tinny sound and dropped bass. Nevertheless, he stumbled upon a $20 pair of headphones with similar reviews and realized that he could switch out the driver and make a decent [...]

[Dan’s] office is awfully hot, but he needed some real temperature numbers that he could show the building management office to justify opening a maintenance ticket. He had seen some simple temperature probe examples online, and decided to build his own using a small AVR chip. Based off a similar temperature monitoring example called EasyLogger, [...]

[Dan] wanted to learn a bit about solid state ignition in engines; to get started he needed a test subject, so he decided he would upgrade his old 12 horsepower lawnmower. Originally the lawnmower engine used a magneto coil ignition system, magnetos are simple and very common in lawnmowers. The magneto is designed to produce [...]

[Dan] wrote in to share a project he recently finished up, an autonomous Airsoft tank. The toy tank makes use of a wide array of technologies to get the job done, and will stop at nothing to hunt you down (provided you are wearing an IR beacon). An Arduino board is used to control the [...]

After reading over the proceedings of the 2005 SIGGRAPH, [Dan] realized he could reproduce one of the projects with $50 worth of equipment and some extreme cleverness. [Dan]‘s dual scanning laser camera operates by scanning a laser across an object. The light reflected from the object illuminates a flat surface, and this light is measured [...]

Hackaday forum member [Dan Fruzzetti] wrote in to share a simple, yet useful hack he built just the other day. He and his wife both have Evo 4G smartphones and they were pretty disappointed in the lack of portable charging solutions available. Instead of buying something and modifying it to his needs, [Dan] decided to [...]

Omnidirectional personal transport [Dan] sent us a link to this Honda U3-X personal transport device. It’s kind of like a Segway that can move in any direction but our head already hurts from the thought of going over backward on one of these. How light bulb filaments were developed Now that incandescent light bulbs are about [...]

In what is surely becoming an ever-growing Rube Goldberg machine, [Dan] updated his gum ball dispenser to include a robot arm. We looked in on this human lab-rat experiment that rewards successful maze navigation with bubble-gum just about a year ago. As you can seen in the video after the break he’s added several new [...]

[Dan Roe] has been working on Sculptural Robotics for quite some time, and most recently presented his newest creation: Solar Flowers 2010. Typically, Sculptural Robotics (coined by [Dan] himself) are stand alone, static art presentations made from electronic components and wire. [Dan] of course has taken it quite a bit further; giving all his sculptures [...]

[Dan McGrath] tipped us off about a solution for a problem that most people don’t have. He built a web-based entry system for his garden gate. This isn’t quite as original as that chain and sprocket dorm room system, but it does use a keypad for entry. [Dan's] already got a web server and home [...]

[Dan Fruzzetti's] daughter was delighted to get a motorized vehicle from her Grandparents, but [Dan] was unimpressed with the stock features. The lead-acid battery supplied remarkable life between charges, but the vehicle only had one feature: a go button that routed juice to the bipolar motor. After the break we’ll look at his improvements to [...]
