PIC Sonar rangefinder

Sonar range finder using PIC16F88 Microcontroller

The PIC sonar range finder works by transmitting a short pulse of sound at a frequency inaudible to the ear (ultrasonic sound or ultrasound). Afterwards the microcontroller listens for an echo. The time from transmission to echo reception lets you calculate the distance from the object. PIC Sonar Specification Range ~5cm – 300cm Accuracy +/-3cm […]

Ponyprog Circuit for AVR PIC16F84 Schematic Board

Ponyprog Circuit for AVR & PIC16F84

Comments: All resistors are 1/4W.The circuit is powered by 9…15V DC or AC. When In Circuit Programming (ISP) connectors are used, is possible the programmer to be powered from target’s power source. Diodes D2 and D6 protect the regulator LM7805, when target’s power is used. ‘ XTAL JUMP ‘ is used to cut XTAL when […]

Microcontroller Tutorial 4 5 Creating a Microcontroller Circuit Board Schematic

Microcontroller Tutorial 4/5: Creating a Microcontroller Circuit Board

We are now in the fourth part of the microcontroller tutorial. We have a microcontroller circuit diagram ready. It’s time to make a circuit board. I love this part. This is the “magical” step that takes the idea we started with and turns it into something real. But let’s recap. So far we have learned: […]

A Self-Contained Data Logging Anemometer

I love collecting and analyzing data.  I also love building electronic gadgets.  A year ago when I discovered the Arduino products, I immediately thought, “I’d like to collect environmental data.”  It was a windy day in Portland, OR, so I decided to capture wind data.  I looked at some of the instructables for anemometers and […]

SUN TRACKERS WINGS SCHEMATIC

SUN TRACKER’S WINGS

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 […]

Pimp My Rocket Espresso Machine Schematic

Pimp My Rocket (Espresso Machine)

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 […]

hard drive clock

Hard Drive Clock using PIC16F628

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 […]
