The Atmel ATTiny85 chip is an 8-pin MCU that is totally awesome. If you’ve been programming with the bigger boys (the ATMega series), these are a nice adventure – you’re rather limited in the number of output pins, but a creative design gives us a lot of flexibility in a very small package.

You’ve seen them – those “Apple computers.” Probably in the hands of some Hipster in Portland, while riding his fixie and wearing those thick framed glasses. That pulsating light when Apple laptops are asleep is so … sooooothing. You just want to go to sleep watching it. You know you do.

Today, we’re going to replicate that using our ATTiny85. It’s really easy, and most of it can be implemented in hardware instead of code (!!!).

Apple this week is celebrating the five year anniversary of its Apps Store. If you go to the store, you’ll notice Apple is giving away five games and five apps to celebrate the anniversary.

When it opened its virtual doors, the Apps Store did so with a mere 500 apps. Now, it showcases more than 900,000, with more than 800 apps being downloaded each second.

In total more than 50 billion downloads have taken place since the Apple App Store’s 2008 launch, with more than $10 billion being paid out to developers.

Mixed in among the whopping number of available apps are a few that engineers, specifically, might enjoy. We’ve created the following list of our own favorites as well as some contributed by engineers in the field.

This app is a must-have for anybody in the Tech industry and or people who like to do it themselves. The new updated RepairDB brings a modest library of service manuals to the table. Being the first and only app in the App Store covering LCD’s TV’s, Laptops, DLP’s and more.

Many repairs do not seem worth their while because too much time is spent searching for essential service information. The required information is often not available or needs to be ordered, costing time and money! Shorten your repair time, save time and money when searching for important information.

Since identical failures often occur at some point in a large percentage of a given model or product line, using our app, may help identify the problem and or a solution.

Apple iPhone charger teardown on Ken Shirriffs blog:  [via]

Disassembling Apples diminutive inch-cube iPhone charger reveals a technologically advanced flyback switching power supply that goes beyond the typical charger. It simply takes AC input (anything between 100 and 240 volts) and produce 5 watts of smooth 5 volt power, but the circuit to do this is surprisingly complex and innovative.

With the new device Lantronix xPrintServer you can print documents on your network printer from any Apple iOS mobile device.

Imagine, in your company you have a visit with some Apple mobile device like iPod, iPhone or iPod touch and your visitor from any reason needs to print some document. A problem is, that with a probability near to surety, in a given mobile device no drivers for your printer will be installed.

This problem is elegantly solved by a new device from company Lantronix – xPrintServer. It is a literally „plug´n´play“ or „plug´n´print“ network device. xPrintServer serves as an „interface“ between a mobile device and a printer. Apple iOS device communicates with a network through your company´s WiFi and the xPrintServer sends data to a network printer through an ethernet cable.

In comparison to other common net devices, a configuration is unbelievably simple. Connect the xPrintServer into your LAN through an ethernet cable (to a router, switch, hub or any place in the network), power up the xPrintServer, and the xPrintServer will auto-discover and auto-provision all printers in the network. No other configuration is necessary, no applications or any other software. All that is necessary to do to print is to sign into you company´s WiFi with a mobile device, open a desired web page, e-mail, photo etc. and choose the icon to open the native print menu. Then from the printer options menu, choose a printer through which you wish to print. Finally, select a number of copies and choose „Print“.

Advantages / Features:

  1. network device enabling a problemless printing from any Apple iOS device
  2. supports all devices with Apple iOS 4.2 or higher
  3. no drivers or special SW necessary
  4. printing from the native print menu of a mobile device
  5. extremely simple installation – „plug´n´print“
  6. automatically searches all available network printers, no configuration
  7. a big amount of supported printers

Detailed information will provide you the Product Brief, user guide – Quick Start and the List of supported printers.

SAN FRANCISCO – Apple Inc is famous for relying on low-cost Asian manufacturers to both source and assemble its popular gadgets, but the consumer device giant recently started receiving a critical component in its iPad and iPhones from closer to home – Texas.

The A5 processor – the brain in the iPhone 4S and iPad 2 – is now made in a sprawling 1.6 million square feet factory in Austin owned by Korean electronics giant Samsung Electronics, according to people familiar with the operation.

One of the few major components to be sourced from within the United States, the A5 processor is built by Samsung in a newly constructed $3.6 billion non-memory chip production line that reached full production in early December.

Nearly all of the output of the non-memory chip production from the factory – which is the size of about nine football fields – is dedicated to producing Apple chips, one of the people said. Samsung also produces NAND flash memory chips in Austin…

BBC News – Steve Wozniak’s tribute. – [via]

The co-founder of Apple says he will remember Steve Jobs for his “very quick mind” and “knowing what made sense in a product”. Steve Wozniak, who met Mr Jobs at school and was in a computer club with him before starting the company, said: “How many things do you own in the world… that are ‘I just have to have this… I actually enjoy doing my work on this product’? That’s what Apple brought to so many people.”

“We went into the garage when we were two young people with no money. You have to work out of your home. We had jobs on the side. We had nobody that could loan us money. We had no business experience. We were like a million young people who are so excited about the future they may have some day, in business, making something just out of their ideas. That’s what we were.” — Steve Wozniak

Apple A5 floorplan: [via]

We had decapsulated the A5 a couple of days ago, but as you could see in those early pictures, you can’t tell much of a chip’s layout from the top metal – it’s all power and ground buses. So we have to de-layer the chip down to a level where we can see the block layout of the chip; not an easy thing when there’s nine layers of metal! In fact, these days it’s easier to go in from the back and remove the substrate silicon, and look at the gate level from below. Then we can identify the circuit blocks that make up the full device.
