FC200RC/AB Leopold Tenkeyless Tactile Click Keyboard disassembly

Friday, May 20th, 2011

First of all, I'm not about to go into an in-depth analysis about this board as the geekhack folks did. I'm just about to express some of my opinions and provide some PCB porn pictures.

There are only few keyboards that I consider solid builds. This is one of them. I've preordered this one farily early, got it about two months ago and happily using it since then.

There are several attributes that make a solid keyboard in my opinion. One of them is the materials used and the thickness of the walls of the plastic parts. The switches being place mounted vs PCB mounted is another big indicator. As for this keyboard, the plastic seem high quality and the wall thickness is about 2-3mm which I consider very good properties. It's interesting to note the similarity between the my Filco and this Leopold model. The case construction is pretty much the same except some minor details. As for its design, I rather prefer the Filco because the rounded edges of the Leopold don't appeal to me that much.

The use of Cherry keycap stabilizers has definitely surprised me because I thought that those can only be PCB mounted but these are clearly plate mounted and they seem less wobbly than the Costar stabilizers which makes me consider them superior. I've found a very bad solder joint that has been bridged to a nearby trace but apart from that the quality is very satisffactory.

dumbsvnreview 0.4 released

Tuesday, May 17th, 2011

I could simply name this release as "syntax highlighting coolness" which was really simple to implement on my part because I just had to provide Meld the correct file extensions to figure out the file format. Apart from that, I've worked around an svn bug that provided many redundant parameters to the diff utility.

If you upgrade to this version, please make sure that you update your /etc/sudoers to contain the meld-wrapper script instead of meld.

Go for it!

I've replaced my glossy laptop display with a matte one!

Sunday, May 15th, 2011

I'm definitely not a fan a fan of glossy displays. Unfortunately, glossy screens heavily dominate the market nowadays which is a pain in my ass because it's a not pleasant experience to work with them in bright sunlight. Always working in the dark room is something I was fed up with. I've always wanted a laptop with a matte screen but given the many requirements that I have for laptops that was pretty much impossible and I finally bought my Acer Aspire 8935G-874G100BN laptop about one and half year ago featuring a big ass 18.4 glossy screen.

A while ago I started taking getting a matte screen more seriously and visited the largest laptop shop in my city, Szeged. They let me know that a replacement screen would cost me a small fortune and they eventually concluded that it's not possible for me to get a matte screen. I don't blame those guys because doing such a replacement is a rare feat and not so obvious.

I wasn't about to give up and asked for advice. From this point on, there was no going back. After I disassembled my laptop and got to know that my screen is the N184H6-L02 Rev. C1 model, I was searching for suppliers of the matte version of this screen. Interestingly enough despite some suppliers indicate on the product page a glossy screen, they can provide you a matte version of the same model. Fortunately, Bliss Computers had a last matte model on their stock which I've ordered from them and it arrived to me about one week later.

The replacement procedure is pretty obvious, except one thing. There's a glossy sheet that is part of the case in front of the actual glossy screen. That sheet has to leave forever if you wanna have a matte experience. Removing the sheet involves removing the glue that holds it there and without the sheet the assembled laptop will have a somewhat half-finished, DIY look but nothing too obtrusive.

Enough of words, let the images speak for themselves.

As a final word you may ask whether it was worth paying $115 + $45 shipping for the alternative screen. My answer is that IT WAS A F*CKING BARGAIN! My user experience is so much better this way that I can hardly describe it using words! Some folks say that glossy screens provide sharper contrast but I'm not so sure at all. All I know is that reflection has gone, the image quality is stellar and that my glossy screen is officially for sale.

IBM Model M keyboard disassembly

Wednesday, May 11th, 2011

The IBM Model M keyboard. A piece of history. A symbol of geekdom. A cornerstone of computing. Ok, I've gone too far but you must admit that this is the predecessor of almost every keyboard that we use in our modern age and it all started in 1984.

Although this model is manufactured around the end of '92, its quality is as solid as it can be. Around these times manfacturers have already flooded the market with dome switch shit and the next generation of users didn't have any idea about the keyboards of the golden age. I'm not saying that every people would have loved Model Ms because their noise can be disturing but I'm here to say that the construction quality is far more better than almost any other keyboards that are currently on the market. I can only think of Filco and Leopold as exceptions.

It's a very good sign of construction quality that the keyboard can be taken apart by anyone without breaking anything on it. The ABS plastic is top quality, feels very rigid, the walls are thick and the number of components used is no more than necessary. I love pretty much everything about this keyboard, even though I prefer Cherry MX blue switches because they require less pressure force which I think is more optimal.

Here comes the Flickr set which you're welcome to browse through for your viewing pleasure.
