Arduboy. The Arduboy is a handheld game console with open source software, based on the Arduino hardware platform.

History

Development
The original version of the Arduboy was  thick, with the height and width of a credit card, and was initially designed by Kevin Bates, an american Arduino enthusiast, as an electronic business card.

In preparation for a consumer version, the developer moved to Shenzhen, China to work on the Arduboy at the HAX accelerator.

Later consumer versions replaced the first version's touch-sensitive panels by physical buttons, and include a protective plastic case, raising the thickness to .

A non-production smaller formfactor "Arduboy Mini" was demonstrated in 2019. Another non-production system, the "Arduboy Nano" was demonstrated in 2021 with a smaller formfactor than the Arduboy Mini.

Consumer versions
A Kickstarter campaign was being planned in 2014. Development was funded through a Kickstarter campaign in 2015. The launch price of the original Arduboy was either $29 or $39.

In August 2020, Arduboy announced 'Arduboy FX', an upgraded version that includes a flash memory chip that stores over 250 games on the device itself. This version shipped around 2021 at a price of $54.

Tetris Microcard

As well as the open-source Arduboy itself, a single-game version featuring an officially licensed (non-open) version of Tetris is also available.

Hardware
The Arduboy is open source.

The compute platform of the Arduboy is based on that of the Arduino. Both the Arduboy and the Arduboy FX use an 8-bit ATMega32u4 microcontroller as the primary processor, RAM, and storage device of the system. The system ships with 2.5 kilobytes of RAM.

The Arduboy has 32 kilobytes of flash storage, as well as 1 kilobyte of EEPROM. The Arduboy FX features additional storage through the use of an official modchip, installed either from the factory or aftermarket.

The system uses a  128x64px OLED display of only 1 bit.

Audio is handled by stereo Piezoelectric speakers.

The system is powered for about 5-8 hours on a rechargeable thin film lithium polymer battery with a capacity of 180 mAh. The system has a microUSB connector. The console can also be used as a simple controller or input device for other systems.

Casing is made from both aluminum and polycarbonate.

P-Menthane. p-Menthane is a hydrocarbon with the formula (CH3)2CHC6H10CH3.  It is the product of the hydrogenation or hydrogenolysis of various terpenoids, including p-cymene, terpinolenes, phellandrene, and limonene.  It is a colorless liquid with a fragrant fennel-like odor.  It occurs naturally, especially in exudates of Eucalyptus fruits.  The compound is generally encountered as a mixture of the cis and trans isomers, which have very similar properties.  It is mainly used as a precursor to its hydroperoxide, which is used to initiate polymerizations.

James Hervey Herron. James Hervey Herron Jr. (January 4, 1875 – March 29, 1948) was an American mechanical and consulting engineer, metallurgist, and founding president of the James H. Herron Company of Cleveland. He served as president of the American Society of Mechanical Engineers in 1937-38.

Biography

Youth and early education 
Herron Jr. was born in Girard, Pennsylvania, to James Hervey Herron Sr. and Josephine (Fuller) Herron. He obtained his BSc. in mechanical engineering from the University of Michigan in 1899. Later in 1916-17 and 1920-21 he was student at the Graduated School of the University of Michigan.

Herron had started working in 1889 as apprentice in the sawmill machinery maker Stearns Manufacturing Co. in Erie, Pa. From 1895 to 1897 he was assistant and chief engineer at the Erie City Iron Works.

Further career 
After his graduation in 1899 Herron was draftsman and assistant manager at the Cambria Iron Company for three years; chief engineer at Bury Compressor Company in Erie, Pa. for three years; manager at the Motch & Merryweather Machinery Co, in Detroit for three years; and chief engineer and manager of works at Detroit Steel Products Company for another three years from 1907 to 1909.

In 1910 Herron opened his own consulting engineering firm James H. Herron Company of Cleveland, Ohio. The company provided serves in the fields of chemical engineering, metallurgy, power plan design, etc. After Herron's death in 1948, his nephew and metallurgist Lewis F. Herron took over the business, and in 1997 it was sold to the Dutch Stork B.V., creating the Stork Herron Testing Laboratories. 
 
In 1936 Herron was elected president of the American Society of Mechanical Engineers for 1937-38. In 1943 he was awarded the honorary DSc in Engineering by the Case School of Applied Science, now Case School of Engineering.

Svea Velocipede. The Svea Velocipede was an early bicycle type invented in the 19th century by the Swedish brothers Fredrik Ljungström and Birger Ljungström.

The bicycle employed the today well-established bicycle frame but the drive of the wheel worked according to a completely different principle. The inventors used lever, Stubs Iron Wire Gauge and eccentric instead of chainring, since the bicycle chains used at the time often cracked for a variety of reasons. The bike was driven by pressing the pedal en levers alternately, braked by stepping both pedals at the same time. The freewheel of the Svea Velocipede was patented in 1892.

In connection with Alfred Nobel, the project was further developed and the product sold in a limited quantity of units in Sweden, and the United Kingdom, under the company name The New Cycle Company, to which also George Spaak was connected.  It remained in serial production on the market for about 10 years until hitherto technological problems in the production of bicycle chains were overcome. Although the general preference for circular pedal mechanisms became clear with time, later bicycle models on the market would adopt its foot-operated bicycle brakes as well as its free wheeling hubs.

The Svea Velocipede won a Gold Medal of the General Art and Industrial Exposition of Stockholm in 1897, and a Silver Medal of the Exposition Universelle of Paris in 1900. The model has units represented at the Swedish National Museum of Science and Technology, and the Nordic Museum in Stockholm, Sweden.
