Using MatchBox cars as a switch | Hackaday

http://hackaday.com/2009/09/15/using-matchbox-cars-as-a-switch

August 23, 2016. Using MatchBox cars as a switch. September 15, 2009. Atduskgreg] posted this interesting setup to flickr. He’s using two toy cars as a switch. He has wired into their metal undercarriages so when they collide, the circuit closes. We’ve seen some. Home made interface items, but usually they are posted with a clear purpose or a project. This one is a little puzzling. Does he intend to keep using the cars or was he just fooling around? Posted in Arduino Hacks. Newer Comments →. And @dan: I ...

http://hackaday.com/2010/01/04/bt-phone-is-much-more-than-retrofit

August 21, 2016. BT phone is much more than retrofit. January 4, 2010. Santiago] turned his Ericfon into a Bluetooth phone. This is completely different from the handset retrofits. We looked at last month. This is because he didn’t simply crack open a BT headset and cram it into his phone. He developed his own hardware for full functionality. This is an open source. Project with available hardware details. Posted in Cellphone Hacks. TOBI the tool bot →. January 4, 2010 at 8:42 am. That is pure fantastic.

August 20, 2016. Dell Mini 9 OSX install. February 21, 2009. Installing OSX on commodity PC hardware has advanced a lot since the early days of OSx86 when Apple switched to Intel. With the advent of netbooks. The Mini 9 is a very nice machine and according to Boing Boing Gadgets’ chart, one of the most compatible with OSX. Earlier this week you could purchase a new one for just $200. For Gizmodo’s install, they used a Leopard retail DVD with [Type11]’s bootloader. Posted in computer hacks. 8220;why&#8221...

http://hackaday.com/2010/01/06/arduino-io-speed-breakdown

August 21, 2016. Arduino I/O Speed Breakdown. January 6, 2010. Has worked out how long it takes for an Arduino to perform various I/O operations. Takes the longest, followed by analogWrite(). Arduino really falls behind when it comes to digital pin I/O: digitalWrite(). Takes a whopping fifty times longer than a direct bit write to a port register! Posted in Arduino Hacks. CES update: January 5, 2010. Update: more pink wireless-terminal hacking →. 45 thoughts on “ Arduino I/O Speed Breakdown. This might h...

Introduction to FTDI bitbang mode | Hackaday

http://hackaday.com/2009/09/22/introduction-to-ftdi-bitbang-mode

August 21, 2016. Introduction to FTDI bitbang mode. September 22, 2009. It was an interface that launched a thousand hacks. Near trivial to program, enough I/O lines for useful work, and sufficiently fast for a multitude of applications: homebrew logic analyzers. And LED light shows. To name a few. Fear not, for there’s a viable USB alternative that can resurrect many of these classic hacks! And if you’ve done much work with Arduino, there’s a good chance it’s already lurking in your parts drawer. If one...

August 20, 2016. October 21, 2009. Aaron] A.K.A. [ A1ronzo. At SparkFun has put together a hackable USB Geiger Counter. He gets the Geiger counter to work as a random number generator. Later, he analyzes and discusses how well it works as a random number generator. In the past, we have seen a number of radiation detectors hacks such as the Mr. Fission. Digital Geiger counter, a count accumulator. And a Polonium detecting pen. Bluetooth cartridge for Nintendo DS. Gear clock →. October 21, 2009 at 3:15 pm.
