Here are where I will place my witterings on matters geekiness.
On a recent browse of the Internet as I tend to do, I came across an interesting yet simple project that interested me. It is on a blog named desireableaudio, a communal blog with several members. Panzer would appear to be the author of this item.
Now the subject of cable burn in is a contentious one. The idea is that audio cables change their properties after use in their current location. Manufacturers of high end cable will quite often recommend some burn in time before evaluating their cables. Now if only there was a quick way of doing this?
YC, over on his blog Finetone - An Audio Odyssey has released pictures of his latest project, a passive preamplifier. Passive? Are pre-amps not meant to be active devices?
YC doesn't think so, and even though details are not yet complete about the design of his build, he gives some persuasive reasoning as to his choice to go passive with this pre-amp.
His design he mentions is based on the Audio Synthesis Passion, externally the first images he has released bear a close resemblance with a neat black anodised case and gold detailing.
Internally he description belies the attention to detail that he has bestowed on this pre-amp using the similar ingredients to the Audio Synthesis. High quality wiring, a stepped attenuator and more.
I have been very busy working on the site over the last couple of weeks. One or two changes to the appearance of the site have been the result. I hope that you like the Tag cloud that has appeared in the top left hand corner. I am still making my mind up whether I am happy with its final resting place, however I am planning to run with it for a week or so to see if it gets used. Comments on it are very welcome.
Other differences you may not have noticed, they are more in the back end of the site. Last Sunday I had the Hard drive silencing article featured on the front page of www.slashdot.organd the traffic volume shot up. Its a slightly surreal experience sitting in your pyjamas, hangover raging, watching the visits to your site rise from 150 visits per day up to several hundred visits every minute. Needless to say, the "curse of slashdot" befell the site after a few hours and my service provider's servers shut down the site. It took a coupe of days of e-mails backwards and forwards to get the site back on its feet.
Needless to say I have had to learn some emergency coding. I wanted to be ready if the site gets traffic of this magnitude again. I think that I am now as ready as I can be should the traffic levels peak like this again. I have placed some code that should distribute the site traffic to a mirror network when the server is under pressure.
All this new learning has eaten into my project time recently. Fortunately Aleš Mravlak has been busy, submitting an interesting and informative article about the Sure Tripath TA2024 evaluation board that he bought from Arjen Helder in china. He has modified the board extensively. Impressive work I think that you will agree.
Another author to submit recently was Robert Powell who contributed an article on his succession of Gainclone Amplifiers. I especially like the bread bin that he adapted as a case. Very imaginative. Check out also his obscure sugar puff reference. I bet you go "Eh? Oh yeaaaaaah... How true"
So there we are, a busy couple of weeks for the site and for me. Frusrating slightly that i have not managed to pick up a slodering iron for a while, but gratifying also to have received so many visits recently. I hope that I can continue to supply content that interests so many readers, both from my own project box and also from the project boxes of other hobbyists, I am sure we all agree that Aleš and Robert have made interesting and valuable contributions!
Last week Robert Powell was good enough to post an article on his modifications that transformed a Sony Playstation 1 into an audiophile CD player. Not only did this spark the interest of many visitors to the site, but it also got me into thinking. Here's how i got on in my hunt for my own Playstation...
At Justblair's Audio & Electronics Pages we are building a resource for all amateur audio and electronics enthusiasts to enjoy, learn and perhaps even be inspired.
In order to do this I want to build up a collection of quality articles that cover what is a broad subject. This is where you can help.
The first time that I saw the momolight project, I knew that I had to build one.
For those of you who have not seen it, Momolight is a homebrew version of the Philips Ambilight system. It is a set of Red Green and Blue lights, either LED or Cold Cathode which controlled by a microcontroller. Using PWM, any colour can be made from the RGB lights. The lights are mounted on the rear, in left, right and top positions, of your TV
This week has been an interesting week for the site. www.justblair.co.uk has seen a large increase in visits in the last week.
The site has been roughly doubling the number of unique hits week on week since I started it on the 4th of August this year. Hopefully the increase in content is going to keep your interest and keep people coming back with their friends.
