iHippo – The Artificial Intelligent Toy!

If you’ve watched the Disney animated movies, “Madagascar 2: Escape to Africa”, then you must have entertained by the Hippopotamus inside the movie! I bet you also very familiar with this slogan, “I like to move it, move it” too, isn’t it? By the way, are you interested to develop a smart and interactive toy here? Well, have a closer look on this iHippo, as it’s an artificial intelligent toy. This iHippo is an amazing toy that based on the Pic32. Beside that, it contains a 223-unique and original soundbites. The five original full-length songs can be used to help your children go to sleep while the random blurbs will keep you laughing all the time. There are other interesting features about this iHippo: A smart Parental Control Interface – It provides a “block-out” window and allows the parent to program into the iHippo, by simply using a standard RS-232 interface. Wake-up alarm – It can be a useful alarm to get your children wake up in the morning. Smart light sensor – It equipped with an automatic volume control… Continue reading

The SMT Reflow Oven Controller is going to Be Your Great Helper!

You’re tired of reflow soldering with the ordinary way? Then, how about spend some times and build a SMT reflow oven controller to help you off? The reflow oven controller is a device, where it controls a standard toaster oven to perform prototype and small batch surface mount solder reflowing operations. To be more precisely, the reflow can be used to control ovens up to 1800 watts or 15 amps in size. The reflow temperature is being customized through its RS-232 interface. Basically, the SMT reflow oven controller can perform the following three types of cycles: Preheat cycle – It preheat the oven up to temperature Reflow cycle – It runs the oven through the pre-defined temperature. Bake cycle – It uses to drive the moisture from moisture-sensitive components. The H8/3687 microcontroller-based SMT reflow oven controller is a very magical component, where it can transform a conventional infrared toaster oven into an effective reflow oven that can be performing thermal control. Furthermore, the EVB87 evaluation board is helping a lot in this project, as it provides an on-chip analog-to-digital converter,… Continue reading

This Horsepower Monitor is going to Blow You Down!

You might have seen on the TV documentaries before, where there’s a device that specially designed to measure the torque in an automobile drive shaft. Do you have any interest to build up this marvelous Horsepower monitor? If you want, then please read on this article… This Horsepower monitor can provide an output to a vehicle data recording system or a portable computer via an RS-232 interface. Beside that, all of the received data can be combined with RPM measurements from the data recording system for calculating the horsepower! For your information, this horsepower monitor consist the following components: A sensor unit (It attaches to the driveshaft) This sensor unit is a fully powered by battery and it can be used to communicate with the receiver via a 433 Mhz RF data link. A receiver unit (It provides the serial output signal) The receiver unit is powered by the vehicle electrical system! The whole circuitry is operated from two lithium batteries that being mounted in the lower housing half, where it is to maintain assembly balance. In order to conserve… Continue reading

The Marvelous Mega Meter

You can’t get enough with the current electronic bench test instrument and you’re wishing for a more powerful multifunction bench tester? Then, you’re the lucky person, as today you’ll have the chance to look into this Multifunctional “Mega Meter”… For your information, this Mega Meter is based on an ATMega128, where the microcontroller programming is fully done under GCC 3.2 and the PC interface was being programmed by using VB 6. If you refer to the above figure, you can see that there are many electronic components have been used here, such as: Two 0-10 VDC voltmeters (The basic ADC inputs), A 0 – 30 VDC Hi-Z autoranging voltmeter with x10 jumper to give 0 -300 VDC range, A 0 – 3 Amps high side ammeter, 4 channel logic analyzer, Frequency generator (The frequency can be adjusted by modifying the value in OCR1A), Frequency counter (It uses 16 bit TCNT3 in external clock mode to count incoming pulses), Waveform generator that based on a MAX038. Beside that, the board also includes the RS-232 interface, ISP interface, 14.7 MHz crystal, 5V… Continue reading

The dsPIC-Based Laser Light Show Controller – It’s Showtime!

If you always fancied about the laser light shows, but you’ve no ideas how to develop one for yourself, then you must pay attention on today’s topic, as it’s about the dsPIC-based Laser Light Show Controller! This dsPIC-based Laser Light Show Controller can also be known as an arbitrary waveform generator (ARB). For your information, the controller will allow vector patterns to be stored in flash program memory or uploaded from a PC in a vector format. The analog output via two 14-bit DACs has being fed to a commercial analog driver board and two high-speed galvo scanners. For the project, you need to use a Microchip dsPICDEM starter demonstration board featuring a 30F6012 processor chip. The best things about this board is it already has a prototyping area which is populated with the DACs, two connectors, voltage regulators and basic I/O circuitry (an RS-232 interface), where it simplifies the construction of the system. Theoretically, in a basic laser light show, there will be a laser beam is deflected by two galvanometer scanner heads, where each of them moves a… Continue reading
