Tiny, cheap, and dangerous: Inside a (fake) iPhone charger

http://www.righto.com/2012/03/inside-cheap-phone-charger-and-why-you.html

Chargers, microprocessors, Arduino, and whatever. Tiny, cheap, and dangerous: Inside a (fake) iPhone charger. Thoughts on the death of Ma Ailun. A woman in China was tragically electrocuted using her iPhone while it was charging. This seems technically plausible to me if she were using a cheap or counterfeit. So I would be surprised if this electrocution happened with a name-brand charger. Since counterfeits look just like real chargers. I'll wait for an expert to determine if a genuine Apple charger was...

A dozen USB chargers in the lab: Apple is very good, but not quite the best

http://www.righto.com/2012/10/a-dozen-usb-chargers-in-lab-apple-is.html

Chargers, microprocessors, Arduino, and whatever. A dozen USB chargers in the lab: Apple is very good, but not quite the best. When you buy a USB charger, how do you know if you're getting a safe, high-quality charger for your money? You can't tell from the outside if a charger provides silky-smooth power or if it is a dangerous charger that emits noisy power that cause touchscreen malfunctions [1]. The above picture shows the twelve chargers I analyzed. [2]. Next is an oblong Samsung adapter. Apple 10W ...

Chargers, microprocessors, Arduino, and whatever. Teardown and exploration of Apple's Magsafe connector. Have you ever wondered what's inside a Mac's Magsafe connector? What controls the light? How does the Mac know what kind of charger it is? This article looks inside the Magsafe connector and answers those questions. The pins of a Magsafe 2 connector. The pins are arranged symmetrically, so the connector can be plugged in either way. Cutting through the soft plastic block reveals a circuit board, prote...

The Texas Instruments TMX 1795: the (almost) first, forgotten microprocessor

Chargers, microprocessors, Arduino, and whatever. The Texas Instruments TMX 1795: the (almost) first, forgotten microprocessor. The Texas Instruments TMX 1795 microprocessor. Courtesy of Computer History Museum. The story starts with the Datapoint 2200 [1]. A "programmable terminal" sized to fit on a desktop. While originally sold as a terminal, the Datapoint 2200 was really a minicomputer that could be programmed in BASIC or PL/B. Some people consider the Datapoint 2200 the first personal computer.

Reverse-engineering the TL431: the most common chip you've never heard of

Chargers, microprocessors, Arduino, and whatever. Reverse-engineering the TL431: the most common chip you've never heard of. This article is now available in Russian: Майним Bitcoin с помощью бумаги и ручки. Die photo of the TL431. Original photo by Zeptobars. The TL431 is a "programmable precision reference" [1]. But looking at the die shows that internally it is quite different from the block diagram. TL431 block diagram from the datasheet. The TL431 has a long history; it was introduced in 1978 [2].

Life Transitions | "As I mused, the fire burned"

https://sameo416.wordpress.com/2015/07/02/life-transitions

As I mused, the fire burned. Reflection on life as a person of faith. This provided some context to understand why I have been loathe to leave this place, even in the face of two years of increasing frustration (and sometimes great anger) over mismangement and generally missing the point of why we exist. Comfort is a powerful drug, one that numbs the heart and the soul to the point where the pain seems somehow small compared to the danger of change. July 2, 2015 at 2:24 pm.

Terça-feira, 3 de maio de 2016. O que você vai ser quando crescer? Costumava dizer que Mariah não seria engenheira nem a pau. Ela seria médica, aqueles estranhos indivíduos que andam de jaleco branco e conseguem comer um Big Mac logo após uma necrópsia. Hoje eu estou mais reflexivo. Será que a medicina será "a carreira" de 2035? Em primeiro lugar vamos às contas:. A) 9 anos de ensino fundamental, mas ela está no terceiro ano, deve concluir em 2022;. B) 3 anos de ensino médio, concluindo em 2025;. Finalme...
