A Minimal USB CDC ACM aka Virtual Serial Port Firmware for PIC18F4550 READ -> http://www.sparetimelabs.com/usbcdcacm/usbcdcacm.php
Electronics (Brazilian Portuguese) or electronic (European Portuguese) (WHEN 1990: Electronics or electronics) is the science that studies how to control electrical energy by electric means that the electrons have key role.
Power supply – LM317
I received a contact of a player because of the lack of source/charger schematics, so I decided to write a little… The basic scheme is as follows:
USBasp ISP with ATmega8
The circuit is a homemade ISP using an ATmega8 with USB communication and software that allows to program AVR microcontrollers more (ATmega, ATiny) to be used as Arduino, an eco-mode. It is good to always have a backup programmer as a plan B The schematic and firmware can be seen here. Below are pictures of the experience. […]
ATMEGA328 … parte 2
Today I decided I had time, and after reading something more (http://mightyohm.com/blog/products/hv-rescue-shield-2-x/) did on Board of experiences to see if my beautiful atmega was returning to hear me….
Atmega 328P-PU – DEAF!
Gave me the ' spoil’ an ATMEGA328P-PU for having cheated on ' fuses '… But no remedy 🙂
True low cost arduino
With half a dozen euros is an arduino, stable and functional. Bill of material: – 1 ATMEGA328p – 1 16 MHz Xtal – 1 USB2Serie Some rigid wires A white plate of experiments and everything is done 🙂 I haven't figured out the exact amount this cost me yet, but I plan to put all these pieces together […]
In Barometric Sensor Ethershield
This is a preliminary test of a barometric sensor connected to an Arduino board with homemade ENC28j60, that allows you to read the atmospheric pressure in real time using I2C in PA (Pascal) from the point where. It also makes reading of temperature. Is a strong candidate to get in several projects intended for meteorology home. […]
Source/battery charger for 12V 12A (16The peak)
Simple charger and power supply… The circuit is based on LM317 as voltage source (adjustable to a fine-tuning of load voltage)
Nokia LCD 3510 Interface with PIC18F
When a mobile phone stops working in terms of software and even some hardware there are parts that can be used for experiments or projects, in particular the LCD's, saving yourself some money. The aim is to use an LCD from a Nokia 3510 connected to a microcontroller for information visualization, as done in a […]
My Homemade Arduino
As my old arduino was sold (for wine or for something useful), I decided to do a 100% compatible but without the bugs that I had…
