hardware

Another custom embedded Linux board. I recently did a free evaluation of Altium Designer and built this as a way to try it out. The design is based on the SAM9X60 SiP and has a USB device port, two USB host ports, a microSD card, and a low profile 40-pin expansion connector which breaks out GPIOs and peripherals.

A custom Cyclone IV board interfaces with TFT LCD panel, capacitive touch controller, SDR SDRAM. The FPGA superimposes a Julia set on the Mandelbrot set. Touching the screen chooses the set point z0.

A true random number generator project. A PN junction in avalanche breakdown provides the noise source. The noise is amplified, digitized, and conditioned. An LPC1343 provides a USB interface.
