Fun with PCBs

Fun with PCBs

Last year I bought this Etch-Set For Electronic Circuits from Jaycar with the intention of having a go at making my own printed circuit boards (PCBs). I’d had lots of experience working with those experimenter’s Stripboards and Perfboards, which had been more than sufficient for most of the fiddling I did in the past, however […]

PCB layouts using CAD schematic

PCB layouts using CAD

Now the PCB kit I used described how I could draw my circuit layouts directly unto the copper clad board using an special pen with etch-resistant ink, however lacking the dexterity of an artist I chose to get myself some CAD software for generating PCB layouts. After a bit of research I decided to go

DIY Bluetooth RC Car

DIY Bluetooth RC Car

Last year I started a project to convert my (then) four-year old’s busted Radio Controlled (RC) car into Bluetooth controlled one which could be driven using a smart phone or tablet. The original car, modeled after a “Fast and Furious” Nissan Silvia, was a pretty basic RC with 2-channel on-off (non-proportional) style controls, and while Micah enjoyed

How to Interface I2C External EEPROM 24LC64 to PIC Microcontroller1

How to Interface I2C External EEPROM 24LC64 to PIC Microcontroller

Microcontrollers are standalone chips since they have memory and processor embedded. The integrated memory of microcontrollers store embedded code and other temporary variables for the execution of program. CircuitsGallery published many microcontroller tutorials and PIC microcontroller projects. Sometimes we may use non-volatile memories (i2c devices) with microcontrollers in case of storing permanent data. In this

SL4A Bluetooth Controller

SL4A Bluetooth Controller

Having had a bit of an unproductive Easter break I think it’s about time I got back to posting the concluding details of how the transmitter for the Bluetooth RC was implemented. I built the PIC-based motor and servo controller before acquiring the BlueSMiRF module so initially I wrote the following simple Python script based
