32-bit audio effect processor to enhance guitar play

Posted on August 9, 2015 by R-B 2 comments

This 32-bit audio effects processor is randy.day‘s entry to Hackaday Prize 2015 and uses the TI TLV320AIC3204 codec and a PIC32MX150 to create a multifunction guitar effects unit. An OLED and rotary encoder provide menu selection. So far I have 13 effects programmed (pitch shift, Flanger, echo, chorus, etc.) and an E2 tuning tone, and I still haven’t explored the TLV320’s filters and onboard goodies. The ‘3204 is a stereo device, so the second channel can be a mic/aux input, a noise gate input, a pre-programmed sample output … I’m open to suggestions.

Accurate PIC18F25K20-based timekeeper referenced to an atomic clock

Posted on August 6, 2015 by R-B Leave a comment

This PIC18F25K20-based clock uses radio receivers to synchronize the time with that from the GPS satellites or the DCF77 transmitter, both of which are referenced to atomic clocks. This project is a clock with radio receivers which can receive the exact date and time from the DCF77 time signal transmitter or the UTC from the GPS satellites and display it on a 128×64 pixel graphic display. DCF77 transmitter and GPS is synchronized to an atomic clock. So basically this project can “connect to” an atomic clock. This project is an open design: open hardware and open source software.

DIY Game and Watch using PIC18F4550

Posted on July 22, 2015 by R-B One comment

Andrew Hannay has posted this great Instructable about his DIY Game and Watch video game console using the PIC18F4550 microcontroller and Nokia 5110 graphical LCD display. He writes, Back in the 80s when I was a kid, My parents bought me a Game and Watch game called Vermin. It was actually a TimeOut Exterminator. It was a really simple game with just left and right controls and the idea was to hit moles that were emerging from the ground. The screen consisted of pre drawn monochrome lcd images that were turned on and off when they were needed to be displayed.

Microchip is launching “Curiosity” development board

Posted on July 22, 2015 by R-B 2 comments

Microchip is launching a new development board called Curiosity for 8-bit PIC lovers. It supports 8-, 14-, 20-pin 8-bit PIC® Microcontrollers with low voltage programming capability and has an integrated Programmer/Debugger with USB Interface that is fully compatible with Microchip’s MPLAB X development environment. Your next embedded design idea has a new home. Curiosity is a cost-effective, fully integrated 8-bit development platform targeted at first-time users, Makers, and those seeking a feature-rich rapid prototyping board. Designed from the ground-up to take full advantage of Microchip’s MPLAB X development environment, Curiosity includes an integrated programmer/debugger, and requires no additional hardware to get started.

PIC24 Development Board

Brian Dorey shares the schematics and design files for his PIC24 Development board that works with the PIC24FJ128GC006 as well as DSPIC33EP256MU806 dsPIC series microcontrollers. The prototyping board was designed with removable daughter boards for the microcontroller. This means that we can use several different microcontrollers on the same board and if we accidently do something that damages a part of the microcontroller it is easy to replace it without having to unsolder the chip. The PIC24FJ128GC006 includes a USB port so we added one onto the board, this will come in handy if we want to design any devices that
