Christmas Icicle

Christmas led icicle on microcontroller

This LED "icicle" made from mainly blue LEDs. This device can serve as Christmas present or New Year's ornament. The "icicle" can be transformed into a "candle" if to use red and yellow LEDs and to change accordingly its external design. As the body I used two fur-tree toys: transparent plastic icicle and one-half of the Christmas ball. LEDs are placed in the first and second placed the microcontroller board.

Connecting the Joystick from game consoles to your PC

Sega joystick and PC

8- and 16-bit game consoles that were a long time ago very popular, has long lost its leadership in gaming and entertainment market. However, the old games are still popular and yet are perfectly competitive of the interestingness with the modern multi-gigabyte and multi-gigahertz monsters. Today there are many different emulators of old consoles and the Chinese industry is still produced a console itself as well as joysticks to them.

The Christmas LED-Snowflate-thermometer

Новогодняя светодиодная снежинка с микроконтроллерным управлением и индикацией температуры

This LED "Snowflate" made from mainly blue and white LEDs and can serve as Christmas present, Christmas ornament or night light. The device also has a thermometer. Snowflake has 6 beams and every beam contains 8 superbright LEDs. I have used blue and white LEDs with different diameters.

USBasp programmer

USBASP programmer

USB ASP programmer is an popular USB programmer for AVR microcontrollers. There are many different implementations of USBasp, but since PCB dimensions were not suitable for my case, I has made my version of the PCB.

Solderless breadboard - microcontroller designer

Solderless breadboard - microcontroller designer

This breadboard can be used for temporary prototypes and experimenting with circuit design more easily. It is designed for prototyping circuits on chips in DIP-packages and discrete components. The breadboard is intended primarily for prototyping devices on microcontrollers AVR (ATMega8/48/88/168/16/32/8535/...) and АТ89Сх50. The breadboard is based on 40-pin single row connectors PBS (step 2.54mm) and IC-sockets.

t-boot - compact and crossplatform AVR bootloader

AVR bootloader

tboot Loader is a ultra small (only 256 bytes) opensource boot loader for AVR microcontrollers, it's used for programming flash using a serial link between your computer and the microcontroller through any free COM port (or USB to serial adapter).

tboot consists of two parts:
1. on chip boot loader, that resides at the boot section of the flash memory, this loader based on SSBL bootloader
2. windows software, the console utility, that has the responsibility of writing/reading data into/from the microcontroller
