2 pi f Studios

While working on a few assignments, I also took some time to see if I could get together equipment to do some live recording of special seminary and college events, like the St. Joseph Feast day Mass and Vespers, and Convocation. We’ve got some amazing singers and musicians here and I’d really like to get a decent recording of these events!

So I took the preamp I built at Christmas and attached a couple of cheap Radio Shack electret condenser capsules to it. Then I put the unit in an old speaker cover, filled it with foam packing peanuts, glued a plastic tube to the back, and snaked the output cables through the tube. There’s also an exterior clip for the 9V battery and a on/off pushbutton. It works ok, though the electret capsules are really cheap and they do not record high frequencies very well at all.

I went to the chapel tonight and did a test recording of “Holy is His Name” with my homebrew microphone. I then did a recording of “O God Beyond All Praising” with my Shure SM57, though I probably didn’t have it placed in the correct spot. Go here for the recordings.

The photos below are:

3. The back of the microphone. No home project is complete without duct tape!

Hello! Long time no post, eh? Well.. what’s happened since mid-January… The Canadian women’s hockey team defended their gold medal. Unfortunately, the men just lost the quarter-final game to Russia. We will now have a moment of silence for them.

In other news, I was admitted as a candidate this past weekend at Our Lady of Lourdes parish in Saskatoon. From Aaron’s page, candidacy is
“[a] major step in the journey of becoming a priest; candidacy is celebrated when it is clear that the seminarian is committed to the completion of his studies for Holy Orders. The rite includes a public statement, similar to an announcement of the banns of marriage, in which the seminarian presents himself as a candidate for the Holy Orders. The seminarian submits a letter of petition to the bishop, who grants approval of the petition affirming that he has no reservations in the candidate. Candidacy is the final step before a seminarian receives ordination to the deaconate and the priesthood.”

That was a great celebration! Anyone get any photos? Other celebrations during this reading week include Victor’s installation to the ministry of acolyte, Raul and Angelo’s ordinations to the deaconate, and Aaron’s and Lee’s installations to the ministry of reader. Am I missing anybody?

2Ï€f Studios is moving along as well, as I picked up a reasonably cheap mixer board yesterday. It has 2 microphone inputs and 4 stereo line-level inputs. If I were to have a condenser microphone, it can provide phantom power, and if I had an effects panel, the board has auxiliary inputs/outputs. It can also handle tape-level input and output. It’d be cool now to build a simple electret omnidirectional boundary mic. I think I have an electret module kicking around somewhere and simple interface circuits schematics are available online. Also, if anyone wants to give me a nice condenser mic, that’d be cool. And a MacBook Pro, while you’re at it. :-)

BTW, if you want to check out whatever recording I’m working on, I tend to keep files in http://darryldot.org/temp.

Until next time, keep your stick on the ice! Unless you are part of the Canadian men’s hockey team, that is. :-(
