The radio normally allows only two attempts per hour. After each failed attempt, it writes the attempt count to the EEPROM. If power is removed and then restored, the radio will read the attempt count from the EEPROM and stay locked out for an hour.
Here, the EEPROM's chip select (CS) line has been blocked so the radio can't update the attempt count, which allows the one hour wait to be bypassed.
The radio will not start up without the EEPROM, so the EEPROM's CS is connected to the radio's microcontroller to allow the radio to start, then disconnected before code entry.
Once two failed attempts are made, the radio locks out and starts waiting an hour. The power is then removed, and the radio doesn't remember the attempts when it is powered up again.
The background noise is a small DC motor connected in parallel with the radio's 12VDC input. Once 12VDC is disconnected, some residual power still remains in the radio. The DC motor is used to consume this power quickly. If this is not done, the RAM in the radio's microcontroller will persist for some time and the radio will remember the attempts.
Code guessing was sequential starting at 0000. This radio unlocked with code 1611. At two codes per hour, cracking would have taken 33.5 days. With the EEPROM write blocked, two codes can be tried about every 50 seconds, and this radio cracked in under 12 hours.

Expanding on Microchip’s existing 8-bit PIC® microcontroller-based mTouch development tools for capacitive touch, the PICDEM Touch Sense 2 Demo Board enables designers to implement this leading-edge user interface with Microchip’s wide portfolio of 16-bit PIC24F MCUs. Equipped with capacitive touch-sensing keys and sliders, the board allows designers to evaluate this interface in their applications using the Windows-based mTouch Diagnostic Tool, an easy-to-use Graphical User Interface (GUI) that is included in the mTouch Sensing Solution SDK. The software libraries, source code and other support materials that come with the board further shorten development time and reduce design costs.

The low-cost, low pin count PIC24F04KA201 family of 16-bit microcontrollers—the latest to feature nanoWatt XLP extreme low power technology—starts at less than $.99 each in high volumes. The PIC24F04KA family makes it even more cost effective to take advantage of the world’s lowest sleep-current consumption microcontrollers, with typical sleep currents as low as 20 nA. This low power and lower cost, combined with small-footprint 14- and 20-pin package options, makes the PIC24F04KA201 MCU family ideal for battery-powered applications, energy-harvesting applications and other power-constrained applications that are also cost and space constrained.

The Digilent Pmod MTDS is a gorgeous 2.8" touchscreen display with a powerful on-board microcontroller that performs graphics processing tasks. The display is a capacitive touchscreen with QVGA resolution (320×240) and 2 finger multi-touch support.
The most compelling aspect of the Pmod MTDS is the programming experience provided by its Multi-Touch Display System (MTDS) Firmware and the associated libraries. These allow you to design sleek, stylish user interfaces very quickly and with very little code. The timing dependent tasks are handled by the firmware, so integrating the display into existing projects is also a snap. Some of the key functionality provided by the libraries include the ability to draw basic shapes and text, draw images stored on microSD with binary transparency, draw buttons and easily check if they have been pressed, and check the status and location of the user's two fingers. The libraries are supported in Arduino IDE and Xilinx SDK, and have been tested with Ardiuno, chipKIT, and Arty host boards.
This little microcontroller evaluation kit is going to be a long exposure timer/intervalometer when I'm done with it. For about $20, it comes with an 8-bit processor with 16K of flash memory, LCD screen, a serial port for programming (you have to solder your own header to it), a temperature sensor, and other assorted goodies (including 512KB of external flash that I have no use for).
