I thinks this Arduino ProMini is the cheapest and smallest board with full capability based on Arduino. Arduino Pro Mini front view

The Arduino Pro Mini is a microcontroller board based on the ATmega 328P from Atmel (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board 16Mhz resonator, a reset button, and holes for mounting pin headers (2.54mm). A six pin header can be connected to an FTDI cable.

The board comes only with holes (with 2.54mm spacing), without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires.

The pin layout of the Pro Mini board is compatible with the Arduino Mini.

This version of Arduino runs at 5V and 16 MHz, but it has a raw power connector where you can add power supply from 5V up to 12v (DC voltage!).

Meteorite explosion over Russia

A meteorite has flared spectacularly in the sky and exploded over the Russian region of Chelyabinsk near the Ural Mountains. Meteorite explosion over Russia 2013

Around 100 people are being treated for injuries from glass broken by the shock wave generated by the meteorite explosions.

None were serious or required hospitalisation, according to the ministry. Russia’s public health chief Gennady Onishchenko closed schools in the Chelyabinsk region, Interfax said.

magic lantern canon rebel 4Ti 650D You can follow the actual developing status of the Magic Lantern 650D on this blog, "nanomad" is working ver hard on this project hopefully with success.

Anyone who wants to test the pre-alpha of the Magic Lantern 650D can download the firmware here.

Because it is only an alpha version, keep in mind this may be dangerous to your DSLR 650D camera.

DHT22 sensor

The DHT22 is a low-cost digital humidity and temperature sensor. DH DHT22-AM2302-Digital-Temperature-Humidity-Sensor T22 uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal.

This sensor have a very small size and it's simple to use, but requires accurate timing to grab data. The only real downside of this sensor is it very slow, you can get new data from DHT22 once every 2 seconds. I think in most of the DIY projects it is not a big probleme.

How can use DHT22 digital sensor?

Simply connect the first pin (counting from the left) to 3-5 Volts, the second pin to your data input pin (for example Arduino) and the right most pin to ground. DHT22 uses a single wire to send data (it not Dallas One Wire compatible!).

If you want to use multiple sensors in your DIY project for example multi room monitoring, each one must have its own data pin. (Arduino have 13th digital pins)

Magic Lantern 650D

2013 comes with a new super tool for Canon 650D (Rebel T4i). The Magic Lantern team is testing the fist alpha version of ML for 650D (4Ti).

In the first, Magic Lantern was an open platform for developing enhancements to the amazing Canon 5D Mark II and 550D (T2i) DSLR cameras.

Now Magic Lantern v2.3 works on:

- Canon 500D / T1i / Kiss X3: firmware 1.1.1

- Canon 550D / T2i / Kiss X4: firmware 1.0.9

- Canon 600D / T3i / Kiss X5: firmware 1.0.2

- Canon 50D: firmware 1.0.9

- Canon 60D: firmware 1.1.1

- Canon 5D Mark II: firmware 2.1.2

- Canon 650D / T4i 2013 first alpha version (not for public yet)

- For the older Canon 400D / XTi you can use 400plus "firmware"

Magic Lantern is an enhancement atop of the Canon's firmware, allowing you to use many useful features. It does not replace the existing firmware, it is installed on your memory card.
