BALSAMO is dsPIC-based incoming calls filter for your line phone. It can be used to ‘block’ a hidden or blacklisted number. Doragasu, project designer, implemented Caller ID protocol in the firmware due to lack of Caller ID decoder IC.
TinyProjector is a very small portable character projector based on inexpensive laser diodes. It projects a single line of text onto nearby walls and tables from portable and wearable devices like cellphone and PocketPCs that will be connected via wireless serial connection. The current prototype uses PIC microcontroller, PIC16F877, and is capable of displaying 8 characters, […]
The 16FUSB is a software implementation of the USB low-speed for PIC16F628/628A microcontroller. All communication stuff is done by the firmware written in ASM, completely discarding the need to use an additional chip. From the 16FUSB core is possible to add implementations of other protocols such as, for example, I2C, SPI or simple write data […]
This simple counter is built based on PIC16F84A and SAB6456 IC. The SAB6456 is a prescaler for UHF/VHF tuners. It can be switched to divide-by-64 or divide-by-256 by the mode-control (MC) pin. The circuit has an input frequency range of 70 MHz to 1 GHz, has high input sensitivity and good harmonic suppression. This project […]
