Dave shows how the assemblers will production test the µCurrent PCB panels using his new test jigs. And he will does a trial run on 50 µCurrent PCB’s to determine the average testing time. What will take the longest – PCB testing, or wrapping, or packaging?

Vishay has introduced a new concept in panel mounted potentiometers. The innovative design intended for military, (professional) audio and industrial applications consists of a knob driving and incorporating a cermet potentiometer and a switch. Only the mounting hardware and terminals are situated on the back side of the panel reducing to a minimum the required clearance.

The new potentiometer with a value ranging from 22 Ω to 10 MΩ is available as a cermet device for military applications (P16S) or with a conductive plastic element for audio applications (PA16S). The cermet version can dissipate 1 W, the plastic version 0.5 W. With its hermetically sealed case (IP67) the potentiometers require a mounting clearance of only 15 mm. The knobs can be plastic or metal, custom knobs are available on request. [via]

For the last year I’ve been working on a prototype for a Solar Inverter that can be Grid Intertied. A solar inverter takes the 12V DC (or other voltages) from the solar panels and converts it to 120V AC which is the power that most of your household appliances use. A Grid-Intertied inverter allows you to feed that power back into power grid (your house power) to help power your household appliances.

My goal was to design a small inverter, about 100W, that could be used with one solar panel and could be grid intertied. My second prototype (pictured above) has achieved these design goals. So on these web pages I’m going to document the design of the hardware and the software of my solar inverter. I’m releasing these designs to public without restrictions. All I ask is that if you use any of my design that you credit me and add a link back to this website. I hope these designs will help further the work of other people in this area.

2 Watt Solar Panel Powers Bike Sharing @ Voltaic Systems – [via]

Social Bicycles released their revamped design for their bike sharing platform. It is a “GPS-enabled bike that you can find and unlock using your mobile phone.” What we like about it is that it enables companies, organizations and institutions of any size to easily create and manage their own bike share program. We think it also provides a great user experience.

The GPS locator and lock are powered by a battery system which is in turn powered by a dynamo and our 2 Watt solar panel. i.e. if the bike isn’t in motion for several days, the battery is going to stay powered up and transmitting its location.

Steve Lodefink shows us this awesome World Control Panel he built with his son. [via]

My son Harlan and his friend love to play “agents” and he asked me if we coud build “a panel that has a bunch of switches that turn on some random lights”. We worked on it for about 3 weeks, and this is what we came up with. The panel boasts the following features:

This project shows how to build a 63W solar panel using plain materials. It will guide you through everything from building the frame to soldering the solar cells. The frame is build of plywood and solar cells is better to be soldered using a low wattage soldering iron. Finally you add the plexiglass  and your panel is ready. Check construction details on the link below.

In this instructable learn how to build a solar panel from scratch. User “hastyhost” couldn’t find a video shown the entire process of building a solar panel so he decided to make one himself. The photovoltaic panel he build is rated at 63 Watt. Follow the link below to find out how to start.
