I hope everyone watched as a child the legendary sci-fi movie "Back to the Future." I remember how my imagination after this film just flew away. Time travel, flying cars ... Speaking of cars, a car that took off in the movie was not very well-known brand "DMC" (Delorian Motor Company) which is presently not clear what, or whether doing something new whether it continues to produce spare parts for older models, the illuminated in the film. One of the concepts of DMC of 2005.

I once was very keen on cargo robot from the movie "Aliens", very much like to build something. Who does not remember, here's what it looked like in the movie:

The displays of mobile phones has long been used not only in phones.
In recent years found wide application displays on the phones of NOKIA 3310. I myself have tried the library to work with this display, and has written several programs.

Earlier in the blog I wrote about the idea to gather infrared bumper, that would be seen as a time to describe what I did.

As always the way to the result was thorny, with lots of stops and unnecessary turns.
The basis was taken microcontroller ATmega8. The essence of the device is as follows:
- There is a radiator of IR signals, I decided to build a transistor KT315 and IR diode, which was picked up just in the frequency range of the sensor signal IC TSOP1736.

TSOP1736 this device facilitates the work of many enthusiasts. Solving the problem of high-quality reception of IR radiation from the source. The device includes in its housing receiver, amplifier and demodulator, the output signal TSOP1736 get a standard size in the range 0.3-6V
TSOP1736 is often used in remote controls (mostly home appliances), together with the protocol RC5. What gives qualitative data channel.

The structure of the receiver TSOP1736:

Another device in a series of medical devices to microcontrollers. Cardiograph - a device that records and generally maintain or to a memory card or on thermal paper result of the reduction of the heart muscle.

The project is playing Ping-Pong on the microcontroller, the output information is a graphical LCD from NOKIA 3310. As the government is involved in accelerometer. The Game I think is understandable. Most likely in the scheme used MMA7260Q accelerometer with analog output. Since the LCD NOKIA 3310 requires hardware SPI, it is certainly possible, and software bloat, but will increase the amount of code specific. Of this project for me so far is not clear mechanism to organize a certain artificial intelligence, which is a rival in this game.

The project is one of the readers of the site. The robotic arm, the basis of the devices are servo-drives. Management is using a microcontroller, which generates the PWM signals. The case itself and even principle the entire device is constructed from readily available materials. As can be seen PCB can be used not only for printed circuit boards. Controller robot arm connected to a computer through a COM port, the control program runs on your computer.

This miracle was built on the servo, which is used according to the design of 8 pieces.
Typically, these robots are building on the basis of six feet and it's called "Hexapod." As you can see, and with four legs can not teach a robot to move badly. For such devices it is best to use light Li-Polymer batteries, most importantly, be careful with them in charge, with the slightest heat immediately must be disconnected from power.

Visualization of data taken with the accelerometer MMA7260Q In the video, the device consists of an accelerometer MMA7260Q firm Freescale and graphical LCD. The device displays three-dimensional cube, which rotates as a function of position in space of the accelerometer. very clearly demonstrates the accelerometer, and gives ideas for its use in their designs.
