Unschooling
"Read a little, try a little, wait a while, watch." People learn by playing, thinking and amazing themselves. They learn while they're laughing at something surprising, and they learn while they're wondering "What the heck is this!?" My favorite and oldest discussion group is called AlwaysLearning, where the principles underlying unschooling are the topic. On facebook, my less favorite but busier discussion: Radical Unschooling Info If unschooling can't work in the real world, nothing at all can.

Beaglebone + Ubuntu We can install Ubuntu 2-ways. To the external SDCARDTo the internal MMC Installing to the internal MMC requires an SDCARD to install, but the sdcard is not required after that. The process is mostly the same.
Why another Hardware Processor? « Python Hardware Processor
Hardware description languages are good for particular problems (e.g parallel memory calculation jobs). But it is tough to handle sequential execution problems with them. For such problems the sequential execution of a programm often fits well. A standard solution would be to use a Microcontroller Core (e.g. from Opencores written in VHDL).

An introduction to stepper motors
If you’ve been reading Hack a Day for long enough, you know about our infatuation with stepper motors. These precious little devices put the oomph into our CNC routers, 3D printers, robots, and other miscellaneous projects. Steppers aren’t your run-of-the-mill motors, though. [Steaky] posted a great introduction to stepper motors that lets you hit the ground running building any moving project you could imagine. Apart from identifying a stepper and figuring out if it works, [Steaky] goes over how to make these motors turn.

Very simple Arduino capacitance meter using 16 bit timer and analog comparator
As You could see from video it requires only one external resistor. Meter is very simple, but obviously not very accurate or wide range. Theoretically it could measure in 10 nF – 160 µF range. How it Works? Circuit formed from resistor and capacitor (RC circuit) has time constant, it shows time needed to discharge capacitor via resistor to ~37% it’s initial voltage. Calculation of time constant is very simple t=R*C .
App note: CPLD special function pins
Here is some basic information about special CPLD pin functions you might need when getting started with Xilinx or any other CPLD: Global Clock (GCK) pins Many high-speed digital logic designs need a clock signal that reaches all components simultaneously. While any CPLD pin can input a clock signal and distribute it to the design, GCK pins and their internal connections are optimized for clock signals. They are designed to have minimum skew rates, and that all the connection lengths are the same to allow for perfect synchronicity between devices.
Un défi présent dans la vie d'un enseignant des sciences au secondaire est d'être capable de faire de beaux exercices clairs et précis. Faire des circuits électriques à la main et au tableau peur s'avérer laborieux par moment. Alors, CircuitLAb est un outil indispensable pour construire ce genre d'activité. De plus, les élèves eux-mêmes peuvent être en mesure de construire leurs propres circuits. Le concept d'électricité est complexe et parfois nébuleux puisque ce n'est pas de la matière tangible. Alors, pour les raisons mentionnées plus haut, il est encore plus important d'être clair et précis. by frostchrist Mar 15
