Dual Power Supply with 48V Phantom Power Output

Posted December 27th, 2013 by

Presented is another power supply schematic, but this time using adjustable regulators instead of the normal 78xx and 79xx series fixed voltage regulators. These typically provide lower noise output, and the output voltages can be changed by altering the values of resistors, rather than replacing the three-terminal regulators (which can be quite cumbersome).

Presentation Night

Posted December 18th, 2013 by

So tonight was Presentation Night and overall, I think it went pretty well. Things went mostly to plan, and I didn’t make any mistakes in my cello playing (a welcome change from the norm). The first couple of pieces were quite good; Celebration and Song (Robert Sheldon) was a success, as was the National Anthem (it’s hard for someone to boo that anyway) and Edge of Glory (Lady Gaga) was well received.

Cosmic Girl, however, despite being the most fun to play, was a little shaky… The start wasn’t in time and it ended up sounding quite muddy. Oh well, there’s always something.

Hi-Z to Balanced Line Level Converter

Posted December 16th, 2013 by

Presented is a schematic for a simple circuit with a high-impedance, unbalanced input suitable for an electric (or bass) guitar or some sort of piezo pickup, and balanced, line-level output suitable for use with an audio interface with an appropriate input.

Presentation Night Preparations

Posted December 12th, 2013 by

So this week I’ve been rehearsing for the school Presentation Night. Concert Strings has one performance alongside the Latin Jazz Ensemble (in which we can’t really be heard, annoyingly) and three pieces (though one is Advance Australia Fair) as part of the GWSC Orchestra. The pieces are pretty good, especially the one we’re playing with the Latin Jazz Ensemble, thanks to some good synth samples (and bubbly noises) on the keyboard and an electronic drum kit. (Although it still doesn’t change the fact that it’s damn hard to hear us.)

Apparently, I’m getting three awards this year on Presentation Night; one Academic Excellence, one KLDYS program award and one maths related one (maths something-or-rather) which I’m not too sure about. Ms Alway called to tell me there’d been a glitch and the letter I’d been sent said I’d won only the Academic Excellence award and the other two had been sent to the wrong Jason. Some poor person received a letter saying that they’d won two awards only to be informed it was a mistake.

The spam comments are commencing their flow into the website… Seemed a little quiet lately. Things are returning to normal.

Site Reshuffle

Posted December 8th, 2013 by

So today I decided to move all of the non-blog posts to Quux.Baz. The current links here still work, but redirect you when you view the whole posts.

This site will remain my personal site, while informative and instructional posts will go into Quux.Baz.

I plan to blog and post music related stuff here, and post tutorials, articles and projects on Quux.Baz. We’ll see how that works out. Hopefully this restructure will allow me to keep things cleaner (probably not, actually) with the differing topics appearing in different places.
