Let's Rock! The New iPod GPS.

Yes, you read the headline. Apple's next big event, to be held on September 9th, is called
"Let's Rock". And the image included within their invite seems to show a silhouette of an iPod listener jumping off of a rock.

So what's this all about?

Clearly it is about an iPod with new GPS capabilities. Take an iPod, add a GPS receiver chip (like the iPhone), and install a few hundred megabytes of map data (like most handheld GPS units have) and you have a fully capable Apple-branded handheld GPS.

The GPS market has quickly turned into a HUGE market, and it would be silly for Apple to ignore this market. And there is no doubt that Jobs thinks that he can do a much better job than Garmin, Magellan, and TomTom.

Couple that with the fact that virtually all of the GPS devices out there leave much to be desired in terms of usability, extensibility, and update-ability. An iPod-style device will address all these issues, and can undoubtably be priced to radically change the GPS marketplace.

But wait. This looks like it is for road or outdoors. So! That seems to imply that Apple will make it a bit less fragile and more waterproof than the existing iPod line. That seems to be a natural extension to the iPod - there are over one hundred aftermarket waterproofing products available for the iPod.

So there you have it. Apple is going after the GPS market. My money is on Apple - the other players in this market are weak at best.

Repairing an HP Pavillion DV6 Motherboard

Here's my procedure on how to remove and replace the logic board of an HP Pavilion DV6. My model is a DV6-3122US, and many DV6s of the 3000 series are similar. These machines often fail to start due to a motherboard failure. With a motherboard failure, upon pressing power the fan will first spin and the power light comes on. The capslock key will flash white once every 4 seconds, and the f12 key will stay a solid orange, and the screen - although powered up - displays black only. Although the caps lock "single blink" indicator at boot implies a CPU failure, in my experience it is not due to the CPU itself but the supporting components on the motherboard. The only solid solution is to repair or replace the motherboard. Replacement boards are readily available. I bought one and replaced it myself. Disassembly Procedure NOTE: The screws are different sizes, and its important to reinstall them correctly. I color-coded the different screws in the photos...

Various ways of powering the MikroTik hAP

I have several MikroTik RB952Ui hAP AC Lite routers. They're located in closets, basements, attics, and on desktops. Each location results in different needs in terms of power. Happily, the hAP AC Lite is quite flexible when it comes to power. Here I document the three different ways I have powered my MikroTik AC Lite routers. Power Solutions: Active PoE+ Splitter, Passive PoE Injector, and Standard wall adapter Standard Power: MikroTik (or aftermarket) Wall Wart The default way to power the AC Lite is by using its standard "barrel-style" power port, which is far more flexible than your typical router. The AC Lite accepts power between 10 and 24VDC. When using the MikroTik in a desktop configuration, I use the stock 24 volt MikroTik power adapter . The stock adapter output specifications are as follows: 24 VDC 1200 mA 2.1mm barrel Center Positive Passive Power-over-Ethernet solution: TP-Link Power Injector Sometimes it is useful to ...

Hot (and Cold) Attic Tempertures and Electronic Equipment

An unfinished attic can be an extreme environment for electronic equipment, with conditions that are very unlike what is experienced inside normal living spaces. What's the deal with installing electronic equipment in an unfinished and uninsulated attic? I wanted to install a standard WiFi router in my attic to function as a Wireless ISP (WISP) gateway. My attic is a fantastic location from a radio signal perspective, but it is an uncomfortable place for both people and electronic gear. Although the attic is well insulated, that insulation is on the floor, designed to keep the living space of my home at moderate temperatures. As a WISP gateway, my WiFi router is best mounted above the insulation and close to the roof, where the only protection from weather extremes is the wood of the roof and a layer of asphalt shingles. Equipment Specifications and Extremes Almost all electronic equipment has a set of specifications regarding operating environment. These specifications state the...

Sodastream Carbonator Leakage, Usage, and Weight

SodaStream 60L "Carbonator" CO2 cylinders have a specific weight when empty, plus about 410 or so grams for the CO2 they should have when they're "full". A little while ago I went to buy a replacement Carbonator from my local hardware store. The dealer pulled a new Carbonator out of the box and sensed it was lighter than usual. He put the "light" Carbonator in the "empty" pile and sold me a different one. At that moment I concluded that it would be smart of me to weigh both new and empty SodaStream carbonators. Here are the results. Weighing a SodaStream Carbonator - for both Science and Consumer Protection. The dealer told me that sometimes the carbonators leak after they leave the SodaStream filling facility. That means there could be an opportunity for customers like me to get ripped off! The SodaStream cylinders I buy claim to have a net product weight of 410 grams - and that means that a full Soda Stream Carbonator shou...

Fixing a SodaStream Jet, part 1: Disassembly Guide

I've had my SodaStream Jet for years, and once in a while something has gone wrong. Disassembly is the first step to repair. Start with this article to see how to disassemble the SodaStream, and then once you have that down, scroll through my other articles to see how I repaired specfic SodaStream problems. SodaStream Jet Disassembly Guide Tools Required Flat head screwdriver Phillips head screwdriver 1. Remove the Carbonator. Duh. 2. Remove the black panel lever The front big black tilt lever needs to be removed first. Removing this panel is tricky, but it isn't impossible. Looking up at the bottom of the black panel, there are two tabs, one on the left and one on the right. These tabs fully secure the panel in place. The trick is to use a flat-head screwdriver under the plastic to gently lever the tabs out of the way. Note in the pictures how I approach these tabs with my screwdriver. I usually release the left side first, and then I release ...

MacBook: burnt out magsafe connector repair

My MacBook (A1342 model from 2009-2010) stopped working, thanks to a cheap knockoff magsafe charger. The magsafe connector looked burnt with heat-distorted melted plastic and some black carbon surfaces. Plugging in the charger resulted in no lights and no action. My MacBook was dead. First I tried to clean up the connector with some Q-Tips, tooth picks and solvent, but that did little, as seen in this "after" picture (below). The heat generated by the aftermarket charger permanently deformed and distorted the MacBook's magsafe connector. Clearly the damage was significant. Burnt Magsafe Connector - Replacement Required! Looking at iFixIt , I determined that it would not be difficult to replace only the magsafe connector with the right tools. I hoped and prayed that the problem was isolated to the connector assembly and not the logic board. I bought a replacement magsafe connector assembly (available from Amazon) for under $20 and started to rep...
