Do-it-yourself vertikální větrný generátor: jak sestavit větrnou turbínu s vertikální osou rotace. Vlastnosti výroby větrné turbíny se svislou osou otáčení Horizontální větrné turbíny. Electronic Projects. Tripod2pivot2ptTripod Mounts2 Pivot Tripod Mounts The basic Tripod Mount, essentially, has 2 pivot points.
Usually, one pivot is higher than the other by an angle, roughly, the same as the local LATitude. There are variations of these I call a "3 Pivot Tripod" and another I call a "4 Pivot Horizontal Axis" mount. Tripod Tracking Mounts, (2 Pivot Tripod type), are stronger in every way compared to Polar Axis Tracking mounts perched on top of a post.

The Secrets to Connecting Different Solar panels in Series or Parallel- The Definitive Guide In this article we show you: Let’s get straight to the point.
The basics of connecting different photovoltaic panels in series or parallel Mixing solar panels of various voltage or wattage, or produced by different manufacturers, is a frequently asked question by most DIYers. Though mixing different solar panels is not recommended, it’s not forbidden and things would be ok as long as each panel’s electrical parameters (voltage, wattage, amps) are carefully considered. ZeroneBD. Single Axis Sun position Solar Tracking System Project Duration:One Month About This Project: The designed & Construct project aims at tracking the sun to achieve the maximum sun light incident on the solar panel during anytime of the day.
Dual Axis Solar Tracking System with Weather Sensor. Download Project Document/Synopsis Solar power is the fastest growing means of renewable energy.
The project is designed and implemented using simple dual axis solar tracker system. In order to maximize energy generation from sun, it is necessary to introduce solar tracking systems into solar power systems. Full Circuit Diagram Available. Generally, solar panels are stationary and do not follow the movement of the sun.
Here is a solar tracker system that tracks the sun’s movement across the sky and tries to maintain the solar panel perpendicular to the sun’s rays, ensuring that the maximum amount of sunlight is incident on the panel throughout the day. The solar tracking system starts following the sun right from dawn, throughout the day till evening, and starts all over again from the dawn next day.
Solar tracking system circuit Fig. 1 shows the circuit of the solar tracking system. LiPo battery charging from a 1W 5V solar panel – Roger Clark. In my previous post, I reviewed some “5V 1W” solar panels, with a view to using them to power some IoT devices, and in this post I’ll show my experiments and conclusions about using the panel to charge the battery.
LiPo cells have specific charging and usage requirements so that they don’t get damaged. For charging the basic principal is that they require both constant current and then constant voltage charging. Eried/portapack-mayhem: Custom firmware for the HackRF+PortaPack H1/H2. Října 2016.

This ADC adventure was new territory for me and I am still learning my way around.
If you’re in the same boat, then try the introductory videos on Digital & Analog I/O by Jeff Feddersen and Tom Igoe. Also check out the Jeremy Blum’s tutorial where he mentions the constrain and map commands which come in handy during prototyping. From there move to Nick Gammon’s excellent reference on ADC conversion on the Arduino and then wrap up the set with Bil Herd’s ADC tutorial over at Hackaday. Up to this point I’ve been using IC thermometers (TMP102, DS18b20, etc) because they are easy get going, and seemed to offer better resolution than I could get out of the Arduino’s humble 10bit ADC.
But several of the projects I’ve been working on (like Masons hygrometers) have run into their 0.0625℃ resolution limit.

Below is a collection of quick reference diagrams on hooking up multiple 6 volt and 12 volt batteries to create 6V, 12V, 24V, 48V etc as required for energy storage systems commonly found in residential and off grid solar, hydro and wind systems.
These systems are also common in RVs which meshes with a project I'm currently gearing up for: Repalcing my single 12V battery with 4 6V Trojan T-105 RE batteries and replacing my Converter with an Outback 2812 Inverter / Charger.

Could Zinc Batteries Replace Lithium-Ion Batteries on the Power Grid? Slashdot reader sciencehabit shares Science magazine's look at efforts to transform zinc batteries "from small, throwaway cells often used in hearing aids into rechargeable behemoths that could be attached to the power grid, storing solar or wind power for nighttime or when the wind is calm.
" With startups proliferating and lab studies coming thick and fast, "Zinc batteries are a very hot field," says Chunsheng Wang, a battery expert at the University of Maryland, College Park. Lithium-ion batteries — giant versions of those found in electric vehicles — are the current front-runners for storing renewable energy, but their components can be expensive.

This article has been copied by request from my VK1OD.net web site which is no longer online. The article may contain links to articles on that site and which are no longer available. PA0RDT designed a compact active antenna for receiving over the range 10kHz to 30MHz. For the purposes of this article, the integral amplifier is considered part of the antenna system. Build your own Dressler ARA-2000 Active Wideband Antenna, sorta. Saw this posted at the RTL-SDR.com website earlier: Building an active wideband antenna for your SDR - rtl-sdr.com which links to an article at: and I think I'm going to make an attempt to build one of these at some point in time.
Building an active wideband antenna for your SDR. As the RTL-SDR and other SDRs are wideband, we recommend that people use a wideband antenna if they want to scan over all the frequencies. Normally a discone or a scantenna is suggested as the wideband antenna of choice, however there are alternative designs such as the Dressler ARA-2000 which is a type of log spiral antenna that can receive from 50 – 2000 MHz. This particular product is no longer for sale, but an article detailing the breakdown of its construction can be found online. The article shows how to build the antenna from scratch.

In physics, energy density is how much energy per unit volume. Elsewhere on the internets, energy density is the amount of energy per unit mass. The correct term for this is specific energy.It tells you how much energy you get for the weight. The New Wireless Flagship Device or ASUS RT-AC68U.
