MightyOhm - Join the Resistance

Jeff Keyzer, aka mightyohm. Amateur Radio and DIY Electronics Projects are there with this High Wattage Resistor. posts about microcontrollers (mostly PIC and AVR), Arduino, embedded Linux, circuits, DIY projects, and other related stuff. 

MightyOhm - Join the Resistance

Includes PCB with pre-assembled DC-DC converter, all components required to build the kit

AVR HV Rescue Shield Kit 2 - mightyohm.com

The AVR HV Rescue Shield is a high voltage parallel mode fuse programmer for Atmel AVR microcontrollers. It currently supports the ATmega48/88/168/328P series and the ATtiny2313.

AVR HV Rescue Shield Kit 2 - mightyohm.com

Some Features:
  • Version 2.1 introduces a new and improved 12V switching circuit
  • Completely open source. Source code, schematics, layout, BOM are available.
  • Onboard 12V DC-DC boost converter eliminates the need for an external 12V power supply.
  • Support for programming the extended fuse (EFUSE) byte.
  • An interactive mode, where desired fuses can be entered using the Arduino’s serial port.
  • Separate Ready and Burn indicators.

Instant Embedded client - Tuxgraphics

An embedded client that works almost everywhere and all you have to do is: connect it to the network and power it on.

Instant Embedded client - Tuxgraphics

"The idea for a network client that reports data to a server was born a while ago when a marketing company contacted me. They wanted to display water and air temperatures live on their homepage."

Instant Embedded client - Tuxgraphics

The embedded client system uses a DHCP client to obtain an IP address and other network parameters such as gateway address and the netmask from your DSL-router or Cable-router. This process is totally automatic and happens as soon as board is powered on.

The board uploads then periodically measurements to a server in the internet (aka server in the cloud). When you purchase an embedded client board pre-loaded with software then the access to the data receiving server is included.

OpCUBE Project - Object programmable CUBE

Atmel's AVR is most interesting chip, with modern 8-bit RISC MCU and rich I/O performance in less $ price. With tons of document available on web since simple D.I.Y. hardware project to complex system design.

OpCUBE Project - Object programmable CUBE

AVR becomes the value choice for implement "Physical Computing" idea. The proposal of "physical Computing " is made for interaction of hardware control "the real world" with easy software programming.

OpCUBE Project - Object programmable CUBE

MIDE-51 software package on web with ASEM-51 Assemmbler tools for MCS-51 beginner.

MCS-51 is the good MCU for getting start to learn and use. But now.. we have many microcontroller available on market. Modern chips had much more advantage features than old MCS-51 , e.g. Microchip's PIC / dsPIC, Atmel AVR / AVR32 thru high-end ARM base MCU"

Ethernut Open Source Hardware Family

Four Ethernut reference designs are available, based on 8-bit AVR as well as 32-bit ARM7 and ARM9. All schematics and the CAD data are published as Open Source Hardware and may be freely used for private or commercial purposes.

Ethernut Open Source Hardware Family

Ethernut 5.0 Board - The high end generation of the Ethernut board family has been designed for embedded Linux applications. Ethernut 5.0 boards are shipped with samboot boot loader programmed in internal Flash memory, U-Boot boot loader, Linux kernel and a sample Nut/OS application programmed in serial Flash memory and a Linux root file system programmed in NAND Flash memory.

Ethernut Open Source Hardware Family

Nut/OS is a modular, open source, real time operating system for embedded platforms. It is easily configurable and optimized to run on 8 and 32 bit microcontrollers.

Nut/OS Modular Multithreading RTOS

Nut/OS is a modular operating system. Instead of providing a fixed kernel block, all code is packed in libraries. Only those parts are linked to the final binary image, which are directly or indirectly referenced by the application.

AVR Microcontroller Projects

AVR Microcontroller Projects 

This site is dedicated to AVR microcontroller projects. Here you will find schematics and board-layouts , also the program-code, part-lists and pictures of the projects.

Some projects are programmed in assembler with the AVR Studio compiler and others are programmed with the BASCOM-AVR compiler.

AVR Projects Temperature Indicator

picture

This circuit uses a Dallas DS1621 temperature sensor which indicates the temparature of the device. The temperature sensor has an termal alarm output, which becomes high when the temperature of the device exceeds a user defined value.

Running LED 

Running LED_pic3.jpg 

This running LED or LED chaser is a good project for beginners in the microcontroller technology. It is easy to build, and the assembler program code can be easily adapted.

ELektronik Kompendium

Two new circuits with AVR: Universal timer and frequency clock, in addition new software for the ATTiny11-Programmer, in order to be able to program also Tiny12 and Tiny15.

ELektronik Kompendium

Two new circuits with AVR: the fluorescence indicator control with HD44780-Emulation and the simple radio clock with various indicator options. In addition a Perl Script for the RS232-zu-LCD-Konverter for the use with XMMS.

Second update: Transmitter circuit for the RS232-Interface without Microcontroller with 8 entrances, in addition the texts somewhat revises and restructures.

16-bit to seven-segment

16-bit to seven-segment 
 
"This circuit is used to represent a binary word (up to) 16-bit to seven-segment displays. Changes the binary word, the display is updated immediately. If fewer than 16 bits are displayed, the unused inputs can be connected to ground easily. A switch between six different display modes can be switched"
