Flameless Jack-o’-lantern With An ATtiny13

October 21, 2008 by Caleb Kraft 10 Comments

[aballen] wanted to light the jack-o’-lantern this year with something that didn’t actually require fire. After searching for a project that was cheap and yielded decent results, he ended up just making his own. This project utilizes an ATtiny13 and two LEDs, red and orange. The overall build is quick and simple with some very basic code for the flickering. If you really want it more enclosed, there is this similar project using a cheap electric candle. Of course, not everyone has the time or desire to make one that is this realistic. You could always just go the easy way, no microcontroller required.

Why limit it to just lighting up your pumpkin though? Lets take a stroll through Evil Mad Scientist Laboratories hallways and see the Snap O Lantern or the dark detecting pumpkin and the Cyclonolantern.

LED Random Blinking Mood Lighting

What is it about pseudo random flashing LEDs that make us go gaga? We don’t know, but there’s definitely something there. [seligtobiason] has this obsession too. After seeing several more complicated projects, he created this elegant, simple, and cheap piece of art. The entire thing is pretty much just some flashing LEDs, some resistors, and a power supply. It really isn’t anything groundbreaking, but the effort and cost involved are tiny compared to some other similar projects. sure, it doesn’t synchronize over time based on input like the firefly project. But for a quick cheap project, the results are quite nice.

We would put one in our home, right next to the node blinky.

IPhone 2.0 Adds Secure Wipe

June 25, 2008 by Eliot 6 Comments

AppleInsider is reporting that iPhone Software v2.0 will add a secure wipe feature. The screenshot above shows the text “This will take about an hour.” added to the normal erase feature. This time is used to overwrite data to the disk multiple times. The need for secure phone erasure came to light after a researcher was able to recover personal information from a refurbished iPhone using forensic tools. Since then, a few people have published techniques for obliterating personal data using either the GUI or the more thorough command line method. Remote wipe has also been added to the new firmware in case the phone is stolen. We’re happy to see security being made easily accessible to nontechnical users and expect that remote wipe will become standard on laptops in the future.
