Marine Engine Maintenance
Saved by uncleflo on February 12th, 2022.
If you encounter problems or need to carry out routine maintenance on your boat's engine then the following steps can be taken. For most small boats that have portable outboard engines which can be easily removed, cleaning and repair work can be carried out at home or in a repair shop. Larger craft, such as cabin cruisers, powerboats and larger yachts, which are powered by diesel or gasoline inboard or inboard-outboard engines, may have to have ther engines removed for major overhauls. Once the problem has been established you may need to contact a supplier to obtain the specialist part. Watercraft Services (UK) are Manufacturers, Importers and Distributors of Aftermarket Marine Engine components, including Starters, Alternators, Exhaust Manifolds, Drive components and many other items.

RP2040 Launches Rocket Flight Computer | Tom's Hardware
Saved by uncleflo on January 27th, 2022.
Putting Raspberry Pi boards into space is nothing new, but the method of achieving orbit often differs. While the Astro Pi computers headed for the final frontier onboard a SpaceX Falcon 9 rocket, there are some decidedly lower-tech approaches including, as detailed on the Tindie blog, this $45 RP2040 flight computer from Finnish designer Dan Invents. Combining the RP2040 controller with an altimeter, accelerometer, temperature sensor, and enough juice to power two servo motors (for parachute deployment on the way down), the Rockit (rocket operation computing kit) weighs just 0.18oz (5g) and measures 1.73 x 0.9 x 0.35 inches (44 x 22 x 9 mm). It comes with an open-source firmware pre-installed, and can be tinkered with and updated over micro USB. There's a 16-position rotary switch for adjusting parameters such as start and end positions for the servos, and also a buzzer, so you can more easily find your rocket after a successful landing. Compared to the 2MHz Apollo guidance computer that deposited Neil Armstrong on the Moon, the RP2040 is a powerhouse, and should be more than capable of altitude-based parachute opening and logging flight data from the sensors to a micro SD card. The kit, which costs $44.99, comes with just the board and its pin headers - you need to supply your own battery, servos, cabling, micro SD card and space suit.

Choosing the Right Switch: Know Your AC from Your DC
Saved by uncleflo on December 18th, 2019.
When picking a switch to use in electrical design, many people believe they can use any switch, provided its current rating is more than the maximum load in the circuit. This, of course, isn’t true. Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for designers and engineers to understand how to pick the right switch for their product.

Marine - Victron Energy
Saved by uncleflo on October 11th, 2019.
Whether you are a leisure or a professional sailor, you know how important it is to have a reliable power supply so that your electronics continue to function properly - especially far out at sea. Victron Energy offers a broad range of equipment designed specifically with you and your on board power system in mind. We proudly present to you a new era in freedom and independence. 'Service' batteries provide power for everything except for 'engine-starting'. Demand for on-board electricity has to be matched with an adequate battery bank. Lithium Batteries provide the best solution for high power demand. Compared to lead/acid technology they are smaller and about 70% lighter for their capacity. They can be deeply discharged, without harm. More current is available throughout the discharge cycle …and they can be cycled thousands of times - resulting in a much longer service life. It is also 'easier' to drive power back into Lithium batteries - so charging-time is reduced.

DIY 24v LiFePO4 Solar Battery Bank! Beginner Friendly, 2.4 kWh, Cheap, Full Tutorial! - YouTube
Saved by uncleflo on June 23rd, 2019.
Safety Update: If the cells have a voltage difference of more than .2 of a volt (example: one cell is 2.7 volts, and another cell is 3.5 volts), you should not parallel connect, and instead discharge the higher voltage cell with a 25-50 watt, 1.5-2.7 ohm resistor. Just attach the leads of the resistor to the individual higher voltage cell, and wait till it is at a voltage that is closer to the other cells. When they are within .2 volts of each other, then you can connect them in parallel and allow them to equalize. Another way to do this is to charge the lower voltage cells, but 3 volt chargers are not easy to find, so I would stick to the resistor method. These resistors only cost a dollars each, and you can find them at most electronics supply stores.

Chargers Archives - Battle Born Batteries
Saved by uncleflo on February 24th, 2019.
Battle Born Batteries are made in Reno, Nevada – the Battle Born State. Our batteries are the height of lithium ion technology. We only use LiFePO4 (Lithium Iron Phosphate) in our packs, this is the safest and most reliable chemistry of lithium ion available. They outperform and outlast all other batteries in their class and below their class (lookin’ at you, lead acid batteries). The best part? They’re easy on the planet and your wallet. Green energy is not a trend to us. It’s not a marketing ploy to exploit for sales. We make our renewable, sustainable green energy batteries because they’re simply better than anything else out there, including other green batteries. Compare the specs on our batteries to that grungy, lead acid one in your vehicle and it’s easy to see. Our batteries weigh less, last for more cycles, and they’re made from 100% safe, non toxic, renewable energy that can be charged and discharged over and over again (at a faster rate than any other battery). Not to mention the unbeatable price.

Homemade 100 HP Motor Controller for an Electric Car
Saved by uncleflo on July 19th, 2014.
This instructable explains how to build your own 100 HP (peak) motor controller for use in an electric car or motorcycle conversion. It can take any voltage up to 144v, and the peak current is 500 amps. The cost of the components is a few hundred dollars, which means you can save over $1000 by putting one together yourself. At 144v, you can expect a top speed of around 75 MPH in a car.
