The giant (by radio control standards) servos above are shown adjacent to a Nokia 3310 mobile phone to give an idea of the scale. The arms are 12cm long – perfect for lifting a bank of solar panels (wing). Our local Model Aerodrome in Seaside Road, Eastbourne, supplied these beauties, taking the trouble to source […]
Combining Coffee and Electronics – An Idea for a Project Having played around with fixed function logic ICs, such as the Johnson counter used in the Spindicator project, I was keen to move on and experiment with programmable microcontrollers. I decided to obtain and play with some PICAXE chips, as they looked like they would provide an […]
ave an old hard drive that no longer works? As long as it still spins up chances are you could build a clock out of your old hard drive! You will need some electronic knowledge, some common electronic components and a bit of patience. The clock that is produced isn’t exactly practical since most hard […]
This knight rider light computer is a successor of my first version of the Knight Rider. This version is much smaller and justifies the use of a microcontroller. The project is based on the PIC 12F629 microcontroller. The hardware part Unlike my previous project this light computer is build around the PIC12F629: a microcontroller with […]
RGB REMOTE (pinguino+web+linksys) This project has several uses, it is basically a way to control an RGB LED group (tricolor with common ground) via a web page to select which color we want to show. It may be a way to harmonize a room, change the color of a swimming pool or just fooling aroun […]
This programmer works only with PIC16F84 but it’s great because it never causes errors and works with almost all computers,unlike some other homemade programmers. Step 1: Step one : Materials For this programmer you won’t need many materials.In fact , you will find all you need in your local electronics shop 😉 So here’s what […]
This Instructable will take you on my journey to replace my old Netflix/Vudu Bluray player with a PC based entertainment station for my LCD projector. I wanted to be able to access and control Netflix, Hulu, Youtube, Crackle, NBC, ABC, and the Weather Channel using only a simple remote control. Along the way, I’ll give […]
Every one in the metro cities like Kolkata, Delhi enjoying the luxuries of the metro train ever spared a thought about the train? No, then let me give you a brief idea about the driverless automatic driven and controlled train. But before that let us have a brief recall about types of metro automation. The […]
In the first part of this discussion, the features of ACS712 device were briefly discussed. Now we will use that theory to implement the ACS712 sensor to make a simple DC current meter. The analog output voltage from the sensor is measured through an ADC channel of the PIC16F1847 microcontroller. A voltage to current conversion […]
This post provides the external interrupt code for PIC12F675 microcontroller (e-g when you need to control servo motor which has position encoder, with your PIC microcontroller). As we know, PIC12F675 microcontroller has one GP2/INT pin, which can be used to service external interrupts. This code is written in C language using MPLAB with HI-TECH C compiler. You […]
