Overview Ever since I made the serial controlled RGB LED PWM driver I’ve had many requests for an addressable driver. Well I’ve finally got round to producing one. The code is now completed and tested and the prototype boards are fully working. The design process behind this project was to enable anyone with a bit […]

Laser show for poor man Here’s another useless but cool looking “must build” gadget for every romantic geek. Let me introduce PIC microcontroller based three axis laser spirograph. Step 1 Gathering stuff Design is quite simple and employs regular parts and components but you are free to change/modify it in way you like. At first

One of the advantages using the Microchip PIC microcontroller Pulse Width Modulation or PWM for short is; this PWM peripheral circuit is designed to control the DC motor using the full bridge mode PWM feature. The PWM peripheral works by supplying the correct signal to the H-Bridge DC motor circuit such as speed controlling and

The Serial Peripheral Interface (SPI) is one of the popular embedded serial communications widely supported by many of today’s chip manufacture and it considered as one of the fastest serial data transfer interface for the embedded system. Because of its special in/out register configuration, the SPI master device could transfer its data and at the

This project is an update to the original RGB LED PWM Driver. The new version allows the use of either 5mm LEDs or the square bodied Superflux / Piranah style LEDs. The circuit now uses bipolar transistors rather than MOSFETs which make it more suitable for novice constructors and for the first time this project

With my Grandma’s birthday fast approaching I wanted to put something together that was not too complicated but still sweet enough to make for a cool widget gift. Since fading LEDs never seem to go out of style and grandmas always love to see a heart, putting two and two together here was a no-brainer.

Description As featured in Electronics Weekly Gadget Freak (20/02/2008) The main reason I made this version is that I wanted to fit it in to the base of an Ikea Mylonit lamp. This lamp is made entirely from glass and has a small recess in the base with an entry for the power lead. Since

Throbbing Apple Logo Sticker This little gizmo adds the iconic “sleeping Mac throb” to an ordinary Apple logo decal. The idea for this came about when passing by the Apple Store in Palo Alto, California late one night. After hours, when the store is “asleep,” the lighted logos out front pulsate just like the power
