Class D amp

Introduction

It was about time my amp from the seventies era got upgraded. Over time the sound has become muffled, especially the higher frequencies. What better way to go then the new class D amplification technology. The main advantages are the reduction in weight, space and power consumption. It's also a plus that audiophiles consider it up par with high end audio equipment, and this for just a fraction of the cost of Hi-Fi equipment.

Hi, i'm still revamping this site. If things look weird sometimes, bear with me. Watch out for my latest project involving a class d amplifier to appear here soon.

Ikea Led Lamp

Introduction

After making my pyramid mood light with 12 high power leds, i decided to make a bigger and better version, with the newfound knowledge of possible caveats. After all, the pyramid mood lamp was more of a proof of concept with its shortcomings. I wanted the new mood lamp to be more powerful, so it could also be used in daylight conditions. I did this by using a z-power 3 watt RGB power led. This one led is far more powerful than the 12 ones combined i used before. The colors also mix better because of the wider opening angle and because the rgb chips lay very close together. But you better see it for yourself (please note: all photo's are clickable for a bigger version):

Pyramid Mood Lamp

Introduction

On this page i will explain how i created my first diy colour changing lamp with red, green and blue leds that fade between all colours of the rainbow. I programmed a microcontroller and recycled a plastic pyramid shaped shell in which ferrero rocher chocolates were sold. It's powered by 4 AAA batteries and has several different types of operation.
