Resurrection

I can't believe that I haven't written anything for such a long time. It's not that there was nothing to write about. There was and still is plenty to write about. Especially regarding my flea market and dumpster finds. I've been steadily building my retro computing collection and selling off the surplus in the process. Learning new things and also things that I once knew but forgot. More and more I find myself wanting to write stuff in one place, not just here and there on different forums. That's why I'm officially resurrecting this blog today :-)

PDA vs. Smartphone

It's generally considered that smartphones have won the battle and you will have trouble finding a dedicated PDA nowadays. But have they really won? I think not. What is a smartphone, if not a PDA with a built-in  phone? Making phonecalls is just a tiny part of the package! So what happened is not the death of the PDA but rather a merger. This is good because we don't have to carry two separate devices anymore and it's cheaper too. Would the phones eventually evolve to what they are now without the invention of the PDA? Who knows?

Windows XP: how to disable CTRL+ALT+DEL at Login

By default, Windows XP will ask you to press CTRL+ALT+DEL before you can enter your user credentials. Here's how to get around this:

Go to the Control Panel--> Administrative Tools--> Local Security Policy, select Local Policies --> Security Options, and locate Interactive Logon: Do not require CTRL+ALT+DEL, and Disable that option. Problem solved!

HTPC Cooling Part III.

About a year ago I wrote about how I solved the problem of my HTPC overheating. Well, after recently upgrading RAM to 4GB it seemed like a good idea to come up with a better solution. So I did.

Mod #1: Cable ties! The existing fan was perfect so I used cable ties to attach it to the heat pipes.

Fast, easy, neat and works like a charm!

Mod #2: Case fan also needed silencing. On the first try I used a thermistor. Have yet to see, if this is a satisfying solution.

News: Fractal PC

It's been 8 years since my last PC build and the time has come for me to replace my aging Toshiba laptop. After much thought and price checks I settled for this:

CPU: Intel i3-2100
MB: Asus P8H67 rev3.0
RAM: 2x 4GB Corsair Vengeance Blue 1333MHz
GFX: XFX Radeon 6850 1GB
PSU: Corsair TX 650W V2
BOX: Fractal Design Arc

Got all of this (except the case) from a shop in Austria (www.e-tec.at) and the prices were very reasonable. The build worked out of the box and gave me no problems whatsoever which is a first!

TG3 BL82 mod

In december 2010 I received a used TG3 BL82 compact mechanical keyboard. It was in pretty bad shape but I didn't want to throw it out so I decided to completely renovate it.

The idea was to swap switches for Cherry MX Blue and along the way swap LEDs as well. I got the switches from a fellow geekhack.org member and bought the orange diodes on eBay.

TG3 really has nice and clean soldering. All soldering and desoldering was done at 275C. Since I haven't done anything like this before, it took me almost 7 hours just to desolder the switches and diodes! I estimate that I spent a total of ~14 hours working on the project. Additional time was wasted with desoldering new diodes which turned out not to be bright enough.

The last ingredient was the transparent case I got from Deck thanks to another geekhack member.

Video HowTo: Cherry MX stem&spring swap

A switch is held together by four latches (two to each side). The video shows how you can pop the switch open in 3 easy steps. I did this with a french Goupil G80-1861 keyboard which originally used MX Black linear switches. A Cherry G80-1000 served as a donor for MX Blue stems and springs.

HTPC Cooling

I finally got my hands on one Scythe 100x100x12mm slim fan. It turns at roughly 1000rpm and practically cannot be heard. It only moves 15 CFM which means that the PC now gets hotter than before - approximately 60C . This is quite alright as far as I'm concerned so I'll leave it as is (for now).
