Here is the nixie clock ! PIC16F84A microcontroller Single-digit Nixie, sequential hours, minutes and seconds display DCF-77 atomic clock, with automatic or manual time set-up high voltage power supply for Nixie with only 4 components 24 hours cycle programmable extinction time no MikroC compiler licence needed ! This project will show you how to drive a nixie […]

Radial (centrifugal) fans EBM Papst RadiCal series represent a top in efficiency, power and a silent operation Despite the fact, that basic fan types are known for decades, there´s still a space for improvement. A justification of this is a series of radial (centrifugal) fans RadiCal with backward curved blades from company EBM Papst. Thanks […]

This project is a RS232 & RS485 Interface Board RS232 or RS485 Board will help you provide a seamless connection of either of the protocol RS232 or RS485 with your interfacing circuit. Specifications 5 VDC Supply sourced through the Box Header interfacing connector Either of the two communication protocol available by use of individual IC […]

The CATV Tuner sold by MTM Scientific, Inc can be used for wideband audio and video reception, as described on our other project pages such as the FM Wideband Receiver and Radio Telescope Project. A common requirement in all these projects is the need to program the CATV tuner with a serial bit stream to […]

MaxLife concept diagram. Lifetime cycles are increased, but not a big improvement in energy density (via TI)  Texas Instruments is one of the most dominant technology companies ever. Behind Intel and Samsung, it is the world’s third largest producer of semiconductors. In addition, they are the largest manufacturer of digital signal processors and analog semiconductors. […]

This is a 40 & 28 PIN PIC Development Board The PIC 40 / 28 PIN (DIP) Development / Evaluations board demonstrates the capabilities of Microchip’s 8-bit microcontrollers, specifically, 28- and 40-pin PIC16FXXX, PIC16F1XXX, and PIC18 devices. It can be used as a standalone demonstration board with a programmed part. With this board you can […]

An alternative to using a transistorized H-Bridge circuit is the L298 Dual Full-Bridge Driver. It is very easy to control and it doesn’t require any calculation. Simply knowing your motor’s required current and the IC’s current capacity is enough. For a price though.In order to learn this, you need to first download the IC’s datasheet […]

Fun fact: None of these images are simulated. Every Mooshimeter on this page is gathering real data in real life. The Mooshimeter was born out of our frustrations as electrical engineers at the limitations of the “standard” digital multimeter. Almost every digital multimeter will only let you use one mode at a time, meaning that […]

We always try to know the physical and electrical data like temperature, pressure, current, ac voltage etc. In this project, I’m going to display these data in the real time as well as I’ill record it to a memory card(SD/microSD/MMC card). Here the project can display four different things; ac voltage, environment temperature, relative humidity […]

PIC 16F88 Digital Thermometer Light Meter and resistance ohm meter. My original idea for this project was simply to try and interface the WINTEK WD-C2401P lcd panel to the pic (see my previous post). I figured it would be fun to add a couple of ADC readings to display something useful on the lcd.  Theory […]
