Oktopod Studio – Development Tools for Mechatronics, Robotics and Automation.
Oktopod Studio is a development platform for mechatronics, robotics and automation, which enables creating and controlling low voltage electronic devices, models and home applications /in an extremely simple way/.
Oktopod_Board presents a Programmable Logic Controller (PLC), which features plug and play inputs and outputs for connecting low voltage electronic devices, like: LED lights, DC & servo motors, electromagnets, switches, photo, temperature and magnetic sensors, and so on.

Buzz..Buzzzz..buzzzzzzzz .. That is how a lone mosquito irritates you in the middle of the night trying to convince you that his lullaby is helpful. Insignificant or not, But truly that is the underlying inspiration for this project. The Mosquito repellents have this obnoxious smell that I would not like to sleep in and these loner mosquitoes who just piss me off by buzzing in the ear, you have to choose a lesser evil. Obviously, I turned ON the repellent and in a while it goes off but the smell starts building up and I am too lazy to turn it back OFF, leaving the warmed blanket on a chilly Delhi December Night. The nocturnal dilemma .

This schematic shows the TI AMC1200 in a motor control application. The motor phase current is measured at the resistor (RSHUNT), and the signal is processed through an RC filter before reaching the AMC1200. Also shown are optional protection capacitors C3 and C4. The TI AMC1200 get its high side power from the power supply of the upper gate driver, and a 5.1V zener diode regulates the voltage. The high transient immunity of the AMC1200 and AMC1200B ensures reliable and accurate operation even in high-noise environments such as the power stages of the motor drives.

Most desk fans I have come across have three speeds: Full Speed, Almost Full Speed, and Off – useless if you want just a gentle air movement, and far too noisy if you are trying to get to sleep (in your bedroom of course, not at your work desk!). The squirrel cage induction motors they use have switches to two or more windings – and possibly a capacitor – to reduce the drive current. But unless the drive frequency is also reduced, the torque and speed stability are poor, so minimal speed reduction is usually available on these fans. Using a triac to provide phase control of the voltage works poorly for the same reason, with the speed very sensitive to the triac firing phase angle and fan load, and has a tendency to stall.

This project provides some lighting effect by the blinking pattern of the bulbs connected at its output. Up to 8 Bulbs can be connected in between connector CN2 to CN9 and AC power to control them should be connected at Connector CN10. DC Power should be applied at Connector CN11 in accordance with the polarity marked on this connector. Care should be taken while using this it as it contains Main Power on the board.

Before I began the installation of my Yaesu FT-8800 in my car I knew I wanted automatic power ON / OFF. This is a feature that I have always felt was lacking in my other mobile rigs as I am forever leaving my ham radio on long after I have departed the car.
Let’s start with an action packed video of the finished product, then we can talk about how we got there.

A four-channel remote control built using the EnOcean Pi by Kerry Wong:
In my last couple of blog posts, I did a brief overview of the EnOcean Pi sensor kit from Newark and demonstrated how to compile and run the example code using a Raspberry Pi. In this blog post, I will show a real world example – a four-channel remote control built using the EnOcean Pi in conjunction with the EnOcean pushbutton module.

Power Pic RGB with Infrared remote control is a circuit that generates many colors using a RGB LED and fades between them.
The concept comes from Pic RGB project  where the goal was to develop a fading algorithm between different colors, randomly generated.
Being its third evolution, this time the goal is to use a remote control to change the colors, either by choosing a specific color or by selecting an automatic color fading mode, in which the software will keep changing colors over the color spectrum!

This project described a stereo audio amplifier using two LM386 ICs and a PIC microcontroller to control the volume of the two output speakers. The project uses a DS1868 digital potentiometer that creates a voltage divider network at the input stage of LM386 to control the fraction of signal fed to the amplifier. The potentiometer wiper position is varied digitally by the microcontroller based on the user inputs.

This month, Shawn Blaszak, at Pumping Station: One, shows how to convert a standard TV remote control to solar power. Leave your remote sitting on a sunny windowsill and let it top off the charge in your batteries while you are away from the TV. [via]
