Have you been using float or double variables to perform mathematical operations on embedded systems without a Floating-Point Unit (FPU)? You are doing it wrong! That’s incredibly inefficient. Use fixed-point representation instead. An FPU is an hardware block specially designed to carry on arithmetic operations on floating point numbers. Even though the C/C++ code may work without

Lithium Batteries are indispensable. I have a few project like my own DIY Badge [Post Soon] or a Light Wand for Light Photography and an in-progress Mobile Rejuvenator which use lithium batteries ,usually those re-purposed ones that are sold in Local markets for Solar Lanterns with a capacity of 1100mAh. The lazy me used to

What does the „Tripple Lock“ mean? As already the name says, it is a triple locking – protection against disconnection. The basic and the most important is a sophisticated design with exactly mating parts and a reliable lock. Audible click is a discreet but very useful feature contributing to a correct connector assembly. Optional protections

The dB (decibel) is one of the most common units in engineering, yet also one of the most confusing, especially when it comes to manipulating S-parameters. Here is how not to be confused. The Bel is a fundamentally new unit, which was originally established in 1928 by The Bell System to describe sound levels. This

Summary This is a description of how I designed and built my UV exposure box. After experimenting a bit with dry-laminate photo-resist and liquid UV hardened solder mask I decided to stop trying to improve my toner transfer technique and rather build a proper UV radiation unit for making printed circuit boards. I wanted it

Introduction This is a tutorial on building a Compost Temperature monitoring system. It details how to build a web connected wireless sensor network and shows one possible way it could be constructed. A Medium level of knowledge and skills are required. Basic knowledge of soldering and breadboarding will be very useful. I will assume that
