Fresh hacks every day
[Gnif] was doing what any good hacker does... poking around the insides of one of his tools to see how it works. While in there, he discovered that an EEPROM hack could make the Agilent U1241A function like the U1242A. If you're into this kind of thing the Rigol 1052e hack should have already popped to mind. That was a firmware crippled device that, when unlocked, made the cheaper model behave … [Read more...]
[Jacques] thought his doorbell was too loud, so of course the first thing that came to mind was replacing the electronics and playing a WAV file of his choosing every time someone came knocking. What he ended up with is a very neat circuit: he used a six-pin microcontroller with 64 bytes of RAM to play an audio file. (French, Google translation) The microcontroller in question is a PIC10F322. … [Read more...]
For the longest time, hardware tinkerers have only been able to play around with two types of memory. RAM, including Static RAM and Dynamic RAM, can be exceedingly fast but is volatile and loses its data when power is removed. Non-volatile memory such as EPROMS, EEPROMS, and Flash memory retains its state after power is removed, but these formats are somewhat slower. There have always been … [Read more...]
Webkeys are small, inexpensive USB devices which launch a web browser when plugged into a computer. They're given out as a promotional item, but they can be fun to hack as well. [Brad Antoniewicz] recently got his hands on one and decided to crack it open to see what he could accomplish. The majority of the device was packaging but it didn't take him long to get down to the guts seen here. … [Read more...]
[Dan] has his own Stratasys Dimension SST 768 3D printer. It's a professional grade machine which does an amazing job. But when it comes time to replace the cartridge he has to pay the piper to the tune of $260. He can buy ABS filament for about $50 per kilogram, so he set out to refill his own P400 cartridges. Respooling the cartridge must be quite easy because he doesn't describe the process … [Read more...]
This work clock functions in an unexpected way. With each passing second it displays a random four letter word on the right side of the display. Traditional word clocks tell the time in natural language, but this one is simply used as a learning opportunity. [Iron Jungle] got his hands on the display for just five buck from Deal Extreme. Looks like the price has gone up two dollars but that's … [Read more...]
The teachers at [Jjshortcut's] school were each given a Webkey by the administration as a promotional item of sorts, but most of the staff saw them as useless, so they pitched them. [Jjshortcut] got his hands on a few of them and decided to take one apart to see what made them tick. He found that the device was pretty simple, consisting of a push button that triggers the device to open the … [Read more...]
