A treadle pump is a human-powered suction pump that sits on top of a well and is used for irrigation. It is designed to lift water from a depth of seven metres or less. The pumping is activated by stepping up and down on a treadle, which are levers, which drive pistons, creating cylinder suction that draws groundwater to the surface.

On December 1, 2013, Amazon.com CEO Jeff Bezos revealed plans for Amazon Prime Air in an interview on 60 Minutes. Amazon Prime Air will use multirotor Miniature Unmanned Air Vehicle (Miniature UAV, otherwise known as drone) technology to autonomously fly individual packages to customers’ doorsteps within 30 minutes of ordering.To qualify for 30 minute delivery, the order must be less than five pounds (2.26 kg), must be small enough to fit in the cargo box that the craft will carry, and must have a delivery location within a ten-mile radius of a participating Amazon order fulfillment center. 86% of packages sold by Amazon fit the weight qualification of the program.
Presently, the biggest hurdle facing Amazon Prime Air is that commercial use of UAV technology is not yet legal in the United States. In the FAA Modernization and Reform Act of 2012, Congress issued the Federal Aviation Administration a deadline of September 30, 2015 to accomplish a “safe integration of civil unmanned aircraft systems into the national airspace system.”
In March 2015 the US Federal Aviation Administration (FAA) granted Amazon permission to begin US testing of a prototype. The company responded by claiming that the vehicle cleared for use was obsolete. In April 2015, the agency allowed the company to begin testing its current models. In the interim, the company had begun testing at a secret Canadian site 2,000 ft (610 m) from the US border.
The agency mandated that Amazon’s drones fly no higher than 400 ft (122 m), no faster than 100 mph (161 km/h), and remain within the pilot’s line of sight. These rules are consistent with a proposed set of FAA guidelines. Ultimately, Amazon hopes to operate in a slice of airspace above 200 ft (61 m) and beneath 500 ft (152 m), with 500 ft being where general aviation begins. It plans to fly drones weighing a maximum of 55 lb (25 kg) within a 10 mi (16 km) radius of its warehouses, at speeds of up to 50 mph (80.5 km/h) with packages weighing up to 5 lb (2.26 kg) in tow.
Public concerns regarding this technology include public safety, privacy, and package security issues. Amazon states that “Safety will be our top priority, and our vehicles will be built with multiple redundancies and designed to commercial aviation standards.” However, while privacy and security remain concerns, the FAA’s recently proposed rules for small UAS operations and certifications only provides provisions on its technical and functional aspects.
The fact that the drone’s navigational airspace exists below 500 feet is a big step toward safety management.
Concerns over the constant connection of the drones to the internet raises concerns over personal privacy. The primary purpose of drone internet connection will be to manage flight controls and communication between drones. However, the extent of Amazon’s data collection from the drones is unclear. Some proposed data inputs include automated object detection, GPS surveillance, gigapixel cameras, and enhanced image resolution. Because of this, Amazon’s operating center will collect unknown amounts of information, both intentionally and unintentionally, throughout the delivery process. Neither Amazon or the FAA has formed a clear policy on the management of this data.

A vast array of software is available to support your podcasting requirements; some programs offer one stop integrated solutions to all your podcasting needs, while others fill more specific niches. However, every piece of software that you need in order to record and produce a professional, quality podcast is readily available free of charge.
No matter what software you choose to help create and produce your podcasts, you will first have to get your audio into the computer. How you choose to do this is entirely up to you, but is likely to depend on what level of audio quality you want and your budget. At the most basic level you could use your computer’s in-built microphone, but for a reasonable degree of quality you will want a semi-decent external microphone.
1. Audacity – Audio Recorder and Editor
2. WinLAME – Audio Encoder
Once your audio has been recorded and edited (preferably in WAV format) you will need to convert it into a suitable podcast format. The universally accepted audio file format for podcasts is MP3. WinLAME is an excellent piece of free podcasting software designed to convert WAV files into the podcast friendly MP3 format.
3. Mp3Tag – ID3 Tag Editor
Now that you have your podcast MP3 audio file and some suitable artwork for its cover, you will need to embed the artwork into the MP3 file and add some additional tags that can be displayed by the listener’s playback device.

What Is The RedBoard?
Arduino is one of the most popular physical computing platforms available today. It’s an amazing tool for both experienced and budding electronics enthusiasts. It’s part hardware, part software, and part community; all of which come together to create a well-supported, solidly-designed electronics platform.
The best part: the entire Arduino project – both hardware and software – is open-source. The schematics, hardware design files, and source code are all freely available for viewing and modification. Released under a Creative Commons Share Alike license, anyone is free to riff on the hardware design and produce their own version. That’s what we’ve done with the RedBoard. It still looks and acts just like an Arduino Uno, but is slightly modified to make the board better-suited to our purposes.
Description: If you’re new to electronics and programming, the RedBoard Starter Kit is a great way for beginners to get their foot in the door. This little guy is essentially a mini SparkFun Inventor’s Kit (minus the manual which you can find below) and can be taken straight out of the box to help you make a slew of basic circuits, including:
Making (bad) music
Responding to buttons
Twisting a volume knob
Detecting ambient light
Mixing LED colors
This version comes with our newest SparkFun RedBoard! Also included is a multitude of parts and sensors so you can start messing around with projects.
Description: The Digital Sandbox (DS) is a learning platform that engages both the software and hardware worlds. It’s powered by a microcontroller that can interact with real-world inputs – like light or temperature sensors – while at the same time controlling LEDs, motors, and other outputs. The Digital Sandbox is equipped with everything, on board, that you will need to complete 13 experiments including controlling an LED, measuring how loud things are, detecting what the temperature is, and more. Think of this as a SparkFun Inventor’s Kit all in one board!
By interfacing the Sandbox to your computer via a USB cable, the Sandbox can be programmed using the popular Arduino programming environment. To further simplify the learning experience, we’ve designed the Sandbox and its guide around using a simple, “blocky”, programming add-on to Arduino called, Ardublock. Using ArduBlock – a simple, graphical version of the popular Arduino programming language – you will be able to program all of the experiments with a simple graphical interface instead of writing code.
The full-color Digital Sandbox Guide (included) contains step by step instructions of how to connect each circuit with the included parts. Full example code is provided and explained and even includes troubleshooting tips if something goes wrong. The kit does not require any soldering and is recommended for beginners ages 8 and up.
