The unit is light weight (2.5 lb), portable, low cost ($10-$20) and can be used to recharge single cell batteries at from 1-3.5 amps. It can be made from a cordless electric drill in a primitive environment. The simplest way of how to make a hand crank DC generator using a standard 12, 14.4 or 18 Volt Cordless drill

With no modification hook an alligator clip jumper to the two charging terminals (on the bottom that the battery plugs into). See picture below. Note that when a 14.4 Volt drill is laid down pointing to the left then the upper terminal is most likely to be the plus and the lower terminal the minus for these units.

13 Juin 2005 : La ZigBee Alliance publie les premières spécifications officielles de la version ZigBee 1.0 qui sont désormais disponibles en libre téléchargement.

La spécification initiale de ZigBee propose un protocole lent dont le rayon d’action est relativement faible, mais dont la fiabilité est assez

élevée, le prix de revient faible et la consommation considérablement réduite. On retrouve donc ce protocole dans des « environnements embarqués » où la consommation est un critère de sélection. Ainsi, la domotique et les nombreux capteurs et télécommandes qu’elle implémente apprécie particulièrement ce protocole en plein essor et dont la configuration du réseau maillée se fait automatiquement en fonction de l’ajout ou de la suppression de nœuds. On retrouve aussi ZigBee dans les contrôles industriels, les applications médicales, les détecteurs de fumée et d’intrusion et dans la télécommande de la freebox v6.
