Collaborate Disseminate
The ESP8266 was one of the first chips that provided wireless functionality at a cost low enough to be widely popular for small microcontroller projects. This project uses one to …read more Continue reading The WebStick is a Small, Cheap NAS
[Saulius Lukse] has been working on some single board computer, seemingly, running Linux. Naturally, that boots from a microSD card – and as development goes on, that card has to …read more Continue reading Automated MicroSD Card Swapping Helps In Embedded Shenanigans
The SD card first burst onto the scene in 1999, with cards boasting storage capacities up to 64 MB hitting store shelves in the first quarter of 2000. Over the years, sizes slowly crept up as our thirst for more storage continued to grow. Fast forward to today, and the …read more
To some, an SD card is simply an SD card, notable only for the amount of storage it provides as printed on the label. However, just like poets, SD cards contain multitudes. [Jason Gin] was interested as to what made SanDisk’s High Endurance line of microSDXC cards tick, so he …read more
Many a hacker has dug an old flash drive out of the bottom of a backpack, and peeled apart the damaged plastic case to look inside. More often then not, you’d expect to see some SMD chips on a PCB along with a few passives, an LED and a USB …read more

Even the most secular among us can understand why somebody would want to have a digital version of the Bible. If you’re the sort of person who takes solace in reading from the “Good Book”, you’d probably like the ability to do so wherever and whenever possible. But as it …read more
There are plenty of dual SIM phones on the market these days, but most of them are a hamstrung by packaging issues. Despite their dual SIM capability, this usually comes at the expense of the microSD card slot. Of course, hackers don’t accept such nonsense, and [Tweepy] went about crafting …read more

Security researchers at CheckPoint have warned about a new danger for our mobile devices, using a vulnerability that goes through the microSD cards. These forms of modified microSD cards can reportedly allow hackers to take over your smartphone by usin… Continue reading Smartphones Vulnerable to New Form of Attacks Via microSD Cards
What we like most about [GreatScott’s] project videos is that he not only shows making them but also the calculations for selecting parts and the modifications along the way. This time he’s made a mini spy bug that records up to nine hours of audio.
His first task was to figure out if the ATmega328p’s ADC is suitable for audio sampling, but only after he explains how sampling works by periodically checking the input voltage from the microphone. Checking the datasheet he found that the ADC’s fastest conversion time is 13 microseconds, which works out to a sampling rate of …read more
