MacBook to TV via HDMI for under $25.

I recently bought a new, modern HDTV: a 42 inch, 1080p Panasonic LCD TV. And one of the first things I wanted to do with my new TV was to hook it up to my trusty MacBook. Like many modern TVs, my new TV has a VGA input, so I figured that'd be the right way to hook it up. I got the following stuff together:
I plugged the dongle into the MacBook, and I plugged the VGA cable between the dongle and the TV. Sure enough, my Mac's video image immediately appeared on my TV. I figured with a little fine tuning, I'd get a great 1080p image!

I was wrong.

Attempt #1: MacBook to HDTV via VGA dongle and cable


The major disappointment is that many new TVs, like mine, won't accept a high resolution 1080p-class signal over VGA. Although my MacBook's "Display Preferences" control panel displays a huge range of potential video resolutions, very few of them work adequately (or at all) with my TV.

I wound up setting the TV to 1280 x 768 ... quite a bit less quality than I hoped for.

Lots of resolutions, but only a few combinations work -
and none look as great as an HDTV should
.
Only 1280 x 768 worked adequately.


There are some minor disappointments too. The VGA cable is big, bulky, and inflexible. It looks clunky. And the audio was noisy - evidently the VGA video signal "bleeds" into the audio signal, resulting in an annoying hum at low volumes.

The Better Solution: HDMI. But with a Mac?

I was happy enough with my VGA solution, but I was looking for something better.

The story on the street is that Macs don't do HDMI. That isn't exactly the full story. The truth is that Mac's "do" DVI and DisplayPort, and both can be converted into HDMI.

But Apple doesn't sell DVI to HDMI such converters. I figured the complexity of such a device would result in extremely high costs.

So I did some snooping around. I checked out Amazon and discovered this Mini-DVI to HDMI dongle for under $10! "Too low, it can't possibly work!," I exclaimed. But for such a low price, I figured I'd take a risk and buy one. (For those with a new Mac that uses DisplayPort: you'll likely want a Mini DisplayPort to HDMI Adapter instead.)

The Magic: Mini-DVI to HDMI dongle.

At the same time, I bought an inexpensive HDMI Cable and a 3.5mm Male to RCA audio cable.


MacBook to HDMI: Mini-DVI to HDMI, along with audio cable.

I hooked this stuff together with my MacBook, attaching the new dongle to my Mac, the HDMI cable between my Mac and my TV, and the audio cable between the headphone port on my Mac and my TV.

The result? Stunning!

In fact, with the HDMI converter, my Mac can recognize both my TV's manufacturer and its supported video modes. Recall that with the VGA solution, my Mac just showed me a heap of possible settings, some good, many not good.

With the inexpensive HDMI Adapter, my Mac detects
the TV and the mode it supports

I could have improved my audio by adding a TOSLink digital optical audio cable, but since I don't have a modern audio system (another story!), I decided to hold onto my money.

Final Notes

If you have a Mac that you want to connect to a modern TV, HDMI is a great way to go. The cabling is flexible and inexpensive, and the quality is high.

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 ...

Macintosh: Upgrading an eMac

It's been a long time since I wrote this article, but the fact remains: The good old eMac can still be useful if you take the simple steps to keep it as good as it can be.  All can run Tiger, and most can run Leopard - great operating systems for their day with a bit of useful life.  This article describes the procedure I used to upgrade my old eMac, including: Replacing the internal hard disk with a large capacity drive. Increasing the memory for performance Upgrading the operating system Here I'm upgrading a 700 MHz eMac, but the procedure and tasks for upgrading other eMac models should be almost identical. Upgrading versus Replacing My sister's eMac is of the 700 mhz variety, with 256 MB of memory. The machine seemed to be getting "slower", and the original 40 GB disk was becoming jammed packed with photos and iTunes, and within a few months she'd be out of disk space. There were two options to address the problems: upgrade the eMac, or go o...

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...

Excellent DD-WRT Router for Me: Netgear WNDR3400 / N600

My WiFi performance was suffering, and so I decided to do something about it and upgrade my router. When I say my WiFi performance was suffering, I really mean it:  I live in a large high-rise apartment building and there are 100+ WiFi access points visible from my home office.  All of the contentious traffic was severely curtailing my WiFi reliability.  I was lucky to get 1 Mbit/second throughput.  Sometimes I was lucky to stay connected even with my WiFi router in the same room. I decided it was time to go for 5 GHz, which is a WiFi band which is used less frequently and which has a tougher time traversing walls.  And of course I wanted DD-WRT support.  The set of features I was looking for included: Trouble-free DD-WRT support 5 GHz 802.11n Support Simultaneous dual band capability Inexpensive.  Maybe even cheap.  For me this means under $50.  Under $35 is even better! It sounds like an easy task to bring all this together: A...

Robust Installation of an HDHomeRun Networked TV Tuner. 64 OTA channels!

I added an HDHomerun (HDHR) over-the-air (OTA) streaming box to my home network, bringing over-the-air broadcast TV to my computers, phones and tablets.  The HDHR is a big upgrade from my previous setup: using a simple "window mount" antenna directly connected to my TV. A TV-attached antenna is good for watching some TV for free, but the HDHR offers so much more flexibility. Figure 0: HDHomeRun on my basement wall   My original OTA TV setup was haphazard at best. It was finicky, ugly, and hard for other people at home to use. I would actually tape my antenna to a window whenever I wanted to watch OTA TV. Plus, it only worked on my TV and not with my other devices. I wanted a cleaner and more modern OTA setup. After looking at possibilities, I developed two goals: (1) bring my OTA TV into the modern Internet-connected era, and (2) set it up in a reliable and pretty way so that other family members wouldn't have to fool around with the antenna or anything else.  With that,...

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...
