Headphone Amplifier

August 30th, 2007 Simon 4 comments

I have a third generation iPod. It still works, so when its battery died, I replaced the battery myself. It still works well. However, this generation has a problem with sound quality due to low quality components used in the internal amplifier. So, I decided to make myself a decent amplifier to connect to the line level output of the iPod. I just had to build it into an Altoids case.

I based it on the popular CMoy amplifier circuit design, and it uses a stereo Burr Brown operational amplifier with high quality support components.

It sounds amazing, and I can’t wait till my new Sennheiser HD-595 headphones arrive. In fact, these headphones require an external amplifier. The iPod just won’t drive them.

Outlook

Can I just say that Outlook is a steaming pile of useless shit?

I get a lot of email every day, mostly from various mailing lists, and I have to sort the mail based on who the email was sent to. I.e. if it was sent to linux.kernel, I would have a rule saying that it should be moved into the Linux folder. This does not work every time, and I find myself having to sort mail manually. Thanks, Microsoft.

I’ll show you.

Outlook 1

Above: the email in my inbox. Notice the sent-to address. 

Outlook 2

Above: I select a rule to run now. 

Outlook 3

Above: I run the rule, and nothing happens. 

I have tried changing the rule to use specific words in the recipient address instead, and I’ve also tried making the rule client-only. No cookie.

Oh, and there’s no way to make Outlook show the time that an email was sent when using the vertical preview pane mode. Great.

Siggraph

San Diego

I’m in San Diego for half this week for the Siggraph 2007 computer graphics conference. This is the view from my hotel room in La Jolla; no idea why it is so orange out there but I thought it looked cool. As usual my flight was delayed and I got here really late, but on the plus side I blagged myself into driving away in a Prius rental car!

This weekend was pretty random. On Friday we went out on the town for Joe’s birthday and Scott caught his hand on fire with Bacardi 151, shortly after Joe set the bar on fire. Then Scott set a pile of napkins on fire but miraculously managed to blow them out with barely a singe. On Sunday I attacked the huge weeds in the garden with the lawnmower, which worked, but it was a bit wetter out there than I expected and now I have a tonne of mud to remove from the poor mower.
