Electronics Tutorial Videos

On afrotechmods, I found a comprehensive list of video tutorials covering basic electronics. Some of the subjects covered are: PWM tutorial Voltage regulator tutorial Circuit simulation in LTSpice tutorial  

Pulse-width Modulation

On Non-Lexical Vocables there is a easy to follow tutorial on PWM. Or see the PWM video tutorial on afromods page.

Cellphone Diagram

On Cellphone Diagram one can find a lot of schematics for cell phones. It is interesting if you want to learn more on how cellphones are designed.

ARM Cortex M3 Examples

Found a nice page with links to Cortex M3 coding examples over at the page of Martin Thomas. Also found a MCU project database here.

Overview of the STM32 ARM Cotrtex M3

Just found an article at avi.hobby-site.org covering the basic hardware design of the STM32 micro controller. Among other things, it covers things like bus clocks and the basic operating principle of the MCU. An other one, covering the STM32 PINs in more detail, could be found at SZ.

Basic Electronics Tutorials

Found this interesting link to basic electronics tutorials while reading Dinos latest hack.

SpokePOV Kit

Well – I don’t like those Arduinos too much … but that SpokePOV kit just rocks Once mounted on the spokes of your cycle they display animated pictures on your wheels.

STM32 Beginners Guide

On www.punctr.com you can find some getting started guides (in german) on the STM32. There is also an article on how to use GDB remote debugging.

Tutorial on Controlling a H-Bridge with the STM32

I just fished a new tutorial on how to control two DC motors through the TB6612FNG dual H-Bridge with the STM32 Discovery board. The tutorial covers the wiring, as well as the software part.

Create FLV videos with mencoder

Sometimes one needs to embed a video in his blog To do so, it is handy to have the video in FLV format. This could easily be achieved by using mencoder from the mplayer project: mencoder -forceidx -of lavf -oac mp3lame -lameopts abr:br=56 -srate 22050 -ovc lavc -lavcopts vcodec=flv:vbitrate=250:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -vf scale=360:240 -o OUTPUT.flv INPUT.{mov,avi,..}
