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.

Hackman Suite - TechnoLogismiki

Hackman 9.2  is an advanced hex editor, disassembler and template editor. It comes with cryptography capabilities, decoding with algorithms and a fully-featured editor.

Hackman Suite - TechnoLogismiki

With Hackman Hex Editor you can edit any type of file in your hard disk, even your hard disk itself or a process in memory. Data are presented in 6 different ways (modes): ASCII, Hex, Binary, Octal, Decimal and Custom mode. The editor comes with unlimited undo/redo with undo/redo lists, full clipboard control: cut, copy, paste, paste special, clear clipboard, highly sophisticated find and replace, unlimited watches and bookmarks and numerous conversion modes, including Java, C++, VB, ASCII, text and more.

Hackman Suite - TechnoLogismiki

You can always use the Patch Maker, the MS-DOS Executable Maker, Merger/Splitter and Checksums (CRC16/32, MD5, SHA1 and more) to check and / or manipulate files. Embedded cryptographic capabilities (Skipjack, NSA, RCA algorithms), support for macros, inline command bar, numerous plugins and external tools, configurable toolbar, shortcuts and menus, multilingual interface and online help consist a part of the features list.

Reads51 - 8051 IDE C Compiler Assembler

Reads51 is an integrated applications software development system, which runs on an IBM PC or compatible host.

Reads51 - 8051 IDE C Compiler Assembler

Reads51 allows writing, compiling, assembling, debugging, downloading, and running applications software in the MCS-51 language. Reads51 contains a C compiler, relative assembler, linker/locator, editor, chip simulator, assembly language debugger, and host-to-board communications in a user-friendly, menu-driven environment.

Reads51 - 8051 IDE C Compiler Assembler

Graphically, the IDE consists of the main menu, customizable toolbars, and various windows. All windows, except the editor window are dockable. Dockable windows may be attached to any side of the IDE, or left floating anywhere on the desktop

Serial Status Input Circuit

Serial Status Input Circuit

When collecting status input data, a few points rapidly consume many connections requiring distribution panels, multiplex logic and expensive parallel IO devices. This simple serial circuit allows you to daisy chain status inputs up to 16 inputs using only four wires. I chose this circuit for a Subsea System due to the high cost of underwater cabling and connectors.

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.
