USB / DC / Solar Lithium Ion/Polymer charger [v1.0] ID: 390 - $24.95 NOTE: This product is only designed for use with solar panels sold at the Adafruit store. We cannot guarantee this will work with solar panels purchased elsewhere. Please purchase this kit and panels from Adafruit to ensure optimized functionality! Make your projects to go green this summer with our specialized USB/Solar Lithium Ion Polymer Battery charger! This charger is a very unique design, perfect for outdoor projects, or DIY iPod chargers. We've spent over a year testing and tinkering with this charger to come up with a plug and play solution to charging batteries with the sun and we're really pleased with what we ended up with. Easy to use! Our carefully designed charger is designed specifically for solar charging, and will automatically draw the most current possible from the panel in any light condition! Please note! For use with Adafruit Lipoly/LiIon batteries only! 3.7V/4.2V Lithium Ion or Lithium Polymer battery charger Charge with 5-6V DC, USB or 6V solar panel!
Quasar Electronic Kit Module Project UK: Industrial Educational Hobby Making PCBs How to make really really good homemade PCBs Note - this article is original material. There is currently a plagiarised copy of it on the site of an Indian electronics magazine credited to a rip-off artist called Indrani Bose. This page is a guide to producing consistently high quality PCBs quickly and efficiently, particularly for professional prototyping of production boards. With the methods described, you can produce repeatably good single and double-sided PCBs for through-hole and surface mount designs with track densities of 40-50 tracks per inch and 0.5mm SMD pitches. This information has been condensed from over 20 years' experience of making PCBs, mostly as prototypes of boards to be put into production. I will only consider photographic methods in depth - other methods such as transfers, plotting on copper and the various 'iron-on' toner transfer systems are not really suited for fast, repeatable use.

The module is installed directly into the GPIO header pins with no wiring or soldering. It uses the 3.3V, GND SDA and SCL pins. Updated V3.0 - The Rasclock now features an 8 Pin Header input, so boards can be stacked on top! RasClock utilises the highly accurate NXP PCF2127AT chip and features: Very accurate timekeeping (typically ±3ppm or <2 minutes deviation per year). Why do I need a Real Time Clock for my Raspberry Pi? The Raspberry Pi is an ultra-small and ultra-low cost computer. The Raspberry Pi will simply revert back to the standard date and time settings (usually 30 November 1999) when the network connection is removed. The RasClock has been specifically designed for use with the Raspberry Pi and, unlike other RTC's available, can plug directly in to the Raspberry Pi's GPIO Ports. How do I set it up?
Concurrency - Home Reflow Controller V2 - Beta-eSTORE.com including V.A.T. plus delivery costs The Reflow Oven Controller controls your reflow oven using the attached temperature sensors and does not require any modifications to the oven. Conformance to specific time and temperature profiles is necessary in order to obtain the best results when soldering SMD components with solder paste. The Reflow Kit Controller controls your solder oven to maintain compliance with specific time and temperature profiles and achieve optimal soldering results. The boards and components are heated gradually during the preheating phase. After preheating, the temperature is briefly raised to just below the soldering temperature. After this, the temperature is raised to the soldering temperature. The controller emits an acoustic signal to mark the end of the soldering phase. 1 Reflow Controller for controlling your reflow oven A serial interface connection cable is not included.
