Ok, so you burned all the memory chips you had around, and now a nice 7-digit display is standing on your desktop just taking up space. This hack turns your unused Flash Destroyer into a clock using a real time clock IC and some spare logic. Via the forum.

Digital clock from an old nixie tube multimeter
James built a digital clock that displays the hours and minutes on an old Nixie tube multimeter. The multimeter functions as a voltmeter that is reading the output of an Arduino generated voltage. There are still some noise issues to clear up, but all in all it’s a cool looking clock. Check out the video […]
Logic Sniffer: Hacking cheap RFID readers
Aaron decided to hack a cheap USB RFID reader, by using the Logic Sniffer to figure out the internal IC protocol. To make it useful for his projects he decided to hijack the internal bus that has the initial RFID decoding. After some poking around he was able to find the UART TX transmitting pin. […]
Another Logic Sniffer ground mod
Here is a mod to add ground to unused Logic Sniffer probes, like the one built by Tarloth. He grounded the top row of a dual-row female header, and soldered the bottom row to his Open Bench Logic Sniffer. This allowed him to both improve signal integrity, and be able to mate his OBLS with […]
Logic Sniffer hack improves signal integrity
Tarloth designed this cool hack to improve signal integrity of the Open Bench Logic Sniffer. Instead of using the standard 1×18 pinheader, he used a dual row 2×18 header. One row is connected to the board, while the other is connected to GND. Unused signal pins are jumpered to GND using the extra header row. […]
Bus Blaster hack: Flashing a PC BIOS chip
Zougloub modified the Bus Blaster V2 somewhat and successfully flashed a PC BIOS chip. By using the onboard FTDI FT2232H chip in SPI mode, and slightly modifying the CPLD logic, he successfully established a link to the BIOS chip. He was now able to update his BIOS and use a processor with his motherboard that […]
PIC LCD backpack free PCB build and hack
Having built a free PIC LCD backpack PCB, Ezflyr decided to hack its pins to use with his temperature and humidity sensor. He successfully adjusted LCD backpack’s firmware, and developed a small app to display the temperature and humidity information on the computer. Via the forum. If you build a free PCB we’ll send you another one! […]
Power supply connector paper clip hack
Gerard sent a tip for connecting multiple cables to a bench power supply: Here is a simple hack which will allow you to connect, wrap , group quite a few power cables in parallel… and all you need is a paper clip.
Zeno zit zapper tip reset
The Zeno is an acne treatment device with disposable tips that are electronically limited to 45 or 60 uses. Matt did a system teardown that revealed a Cypress cy8c27443 microcontroller in the main unit and a 128byte I2C EEPROM in the tip. He used the Bus Pirate to sniff I2C traffic going to the EEPROM […]
