Didgeridoo, Now Does Real Time Video

March 23, 2010 by Jakob Griffith 8 Comments

Some of you may remember when we introduced you to [Kyle’s] Electronically Modified Didgeridoo. Those same members will have their hearts warmed knowing he’s still playing and advancing on his Didgeridoo, now including real time video processing. There isn’t too many details aside from it being controlled by an ATMega168 and an unknown analog switching chip, and in its infancy it just looks like a bunch of dancing white lines but we expect this to turn into one amazing display.

Oh, and those determined on making their own Electronically Modified Didgeridoo should keep an eye out for the April ’10 issue of Popular Science where the instrument will be featured.

1-Wire LAN With An LCD

March 23, 2010 by Jakob Griffith 14 Comments

[Viktor], one of our favorite avid hackers, has been playing around with 1-wire systems all this month. What started out as a MicroLAN Fonera has turned into an iButton interface, to a 1-wire powered hub, and finally a 1-wire character driven LCD. Anyone looking at 1-wire systems or OWFS could surely benefit from his testing.

However, if you still haven’t gotten your fill of 1-wire goodness, let us remind you of the 1-wire HVAC and IPv6 to 1-wire protocol translator.

[Thanks Juan]

More Functional GPS In Minutes

March 21, 2010 by Jakob Griffith 29 Comments

[Sparky] notified us of his hack to allow interaction with the core of an Aldi GO Cruise 4300 GPS Windows CE OS. All that’s required is a few programs and registry edits to the GPS, which anyone can accomplish within a few minutes. But we suggest you go slow and double-check your work; nobody wants a bricked system. After you’re done you can run such great programs like the one [Sparky] suggest for 4WD enthusiasts, Ozi Explorer.

Tim “The Tool Man” Taylor’s Dream Ride

March 20, 2010 by Jakob Griffith 33 Comments

While surfing one of our favorite websites, we came upon this little jewel. We can’t really tell if this is hack-worthy, or just a deathtrap, so to help decide…

Mechanics crawler + 80cc motor – safety concerns = deathtrap

It’s really that final “Brakes? Why would I need to stop?” that puts this project over the edge. Regardless, check out a video after the break. And please, do not try this at home.

Pure TTL Based Clock

March 16, 2010 by Jakob Griffith 28 Comments

We’ll just say, [Kenneth] really likes clocks. His most recent is a pure 7400 series TTL based one, ie no microcontroller as seen in the past, here, here, and here. The signal starts out as a typical 32,768 crystal divided down to the necessary 1Hz, which is then divided again appropriately to provide hours and minutes.

As far as TTL clocks go, this is nothing too original; until it comes to his creative button interface. By using a not as sexy as it sounds multivibrator, he can produce a clean square wave instead of the figity signals produced from buttons to advance and set the time. Like always, he also provides us with a thorough breakdown of his clock, after the jump. Continue reading “Pure TTL Based Clock” →

Keep Tabs On Your Car Without OBD-II

March 16, 2010 by Jakob Griffith 37 Comments

[Steve] let us know about his MultiDisplay car monitoring system. Unlike traditional systems that rely on interfacing with the OBD-II protocol and existing car computer, the MultiDisplay uses an Arduino and custom shield with a combination of sensors; including temperatures, pressures, throttle, Boost, and etc. The data collected can then be displayed on a 20×4 LCD or streamed to a PC with visualization and event recording.

It’s nice to see half a years worth of work finally be complete and presented in such a clean and professional manner, keep up the good work [Steve]

Storage For Your Hacking Needs

March 14, 2010 by Jakob Griffith 18 Comments

Sometimes your project needs a lot of non-volatile ROM, right on cue [Matthew] let us know how to not only connect, interface, read, and write to SD cards with a PIC over serial, but also how to do the above mentioned with an old PATA HDD. For those without a PIC/serial connection don’t fret, [nada] let us know about his Bus Pirate SD card hack, of which our personal favorite part is the creative use of an old 5.25″ floppy connector as the SD card socket.
