Charging a Car Battery with a Solar Panel and Charge Controller

If you connect a solar panel directly to a car battery, it will eventually overcharge the battery and damage it. That's why you need to use a solar charge controller.

Let's disassemble a solar battery charger

This solar charger was on offer at £9. 99 and the large panel caught my eye. Officially I intend to use it to charge some batteries to power some lights in my shed.

Solar Blazon: How We Designed a Solar Powered Boat - All About Circuits (blog)

I recently wrote an article that served as an overview of Solar Splotch event as a whole. However, I thought it wouldn’t do justice to the work I, my teammates, and the other teams put in if I didn’t provide a full view of what’s universal on ‘under the hood’ in these solar/electric boats. I hope to provide just that, without requiring you to read through a 50-page technical report. Ship Design Hull Designing a good hull is one of the most crucial aspects of building any kind of boat. A lot depends on the smoothness of the outside of the hull touching the water. Of course, it is also necessary to have a hull which will be stable in the water. Here are some notes from last year’s tech story documenting its construction and design:. 2014-2015 Hull Mold (Multiple Use):. This hull design was machined from two pounds of avoirdupois-extruded polystyrene (EPS) foam by Foamlinx LLC (Sunnyvale, CA). A 3D model was made and sent as an STP (a universal 3D format) to a CNC foam router to get an fastidious copy of the design. The EPS foam was then coated in Industrial Polymers compound Styropoxy 7060-1 and sanded multiple times until the bodylines were slick. The exterior of the mold was coated with Meguiars Mold release wax to allow for removal from the mold. A positive mold was also added via fiberglass laid over top. Peaceful Multi-use A vacuum bag can be used Very advanced design capabilities. 2014-2015 Hull Design :. The team acclimated to Solidworks 2014 Professional Edition to make the design. They were inspired by the race boats of the 1970s, the “pickle-fork cat. ” These boats have tunnels for air to ditch through when at speed to provide lift. A center planing hull was added for effective planing while allowing the prop to be becomingly placed within the water. The hull was designed to be much shorter and wider to be more stable and allow for less overall drag. Using knowledge from previous competitions, it's cut away to see that the hull is the deciding factor when it comes to competition. Extremely hydrodynamic Aerodynamic Utilizes air to lift weight out of the water, reducing potter Light Fast Cons -. Small space to work with Relies on stability Very thin boat Turning capabilities are not totally hindered by interior walls due to drag... Drive System Mechanics The mechanical drivetrain depends a lot on the exact motor(s) being reach-me-down. It’s extremely important to properly seal all mechanical joints and parts touching the water. Our drivetrain this year was rather complex as we made a society surface drive and Levi drive which allowed the propeller angle to be changed vertically. A universal joint coupled just behind the sailing-yacht allowed for the proper vertical range of motion of the drive shaft even at over 3000 RPM. This joint was covered by a rubber bellows and coated in nautical grease, with double-sealed metal mounting plates forming a water-tight connection to the shaft from the motor-driven perform stridently.

Accouterments Review (and Interview): Gyde Battery-Heated Women's Calor Jacket and S4 Gloves - Snowshoe Magazine

In the twinkling of an eye you have a battery in your jacket and gloves, there may be no going back. I’ll admit to being skeptical when I first heard about battery-heated clothing. Isn’t wearing a battery akin to wimping out when your definitely should be suffering. However, since getting my own Gyde Women’s Calor Jacket and S4 gloves I’ve decided that I’m done with suffering. This article starts with a mat review and ends with and interview about current technology and the future of the products with Gyde’s Director of Development and Technology, Kayla Stevens. Jacket and Gloves Unplugged. The in the beginning thing that amazed me about the jacket, before even plugging in the batteries, was that just looking at it from the outside, I never would have guessed that its heated. The jacket is well-bespoke, and comfortable with high-quality, water-resistant Permaloft insulation. I’ve worn it many times as-is and it clearly doesn’t use the battery power as a crutch. The jacket is amiable and soft. It has two side pockets and a breast pocket, all with zippers. I love how the jacket is long enough to completely cover my back, even when I’m seated and favouritism forward, yet still presents a sleek yet rugged appearance. Like the jacket, the S4 gloves also are a solid piece of gear on their own. They are both waterproof, windproof, and delay warm. The S4 gloves have comfortable liner and Aqua-Tex insert, surrounded by and outer shell. The gloves allow for a good amount of maneuverability, especially given their exalted degree of insulation. I found that I was able to use the zipper on my pants pockets and eat a granola bar while wearing them. While the gloves feature small loops on one of the fingers for lenient removal, I usually don’t have any difficulty in getting them off. The gloves have a buckle across the back for adjusting their fit. Powering Up. The jacket and gloves both come with lithium ion batteries and a charger. Each glove has a battery and they come with a split charger that can give power to two batteries simultaneously. The jacket comes with a distinct battery and standard charger. The batteries are slightly smaller than my old-school flip cell phone and weight approximately the same amount. In the a jacket, the 7 volt , rechargeable lithium ion battery connects to a wire in an inner nick. The battery has four different heat settings that can be adjusted on the battery casing by pressing the power button. When used in conjunction with a Gyde Bluetooth adapter and smartphone App, the intensify level is further adjustable. The heat generated ranges from 100 F, which is hot enough for Gyde to caution against wearing the jacket on bare skin. The battery lasts from 2 ½ to 8 hours, depending on the excitement setting. On the Calor Jacket, heat is generated from four different hot spots on the chest, back, and collar. The clothes can not be washed in a auto due to concerns about the cords being damaged by the washer, but they can be hand-washed. In the gloves, the battery is more obtrusive because of the smaller size and tightness of the garment. The gloves are merest comfortable when my hands are idle and my wrists straight, but when I bend my wrists, they come up against the middle of the battery. However, I wouldn’t necessarily want to engage in a job like packing my overnight pack or stuffing my sleeping bag while wearing the gloves because of the discomfort at. Source: www.snowshoemag.com
