Announcements and old news

I'm living in the right half-plane these days — as you know, this is a dangerous place to be. To avoid imminent instability, I really need to focus on getting some of my class "backlog" cleared up. And so, once again, there will no club meeting tonight.
However, we are preparing to start the building of the speakers, for those that want to spend the money and the effort. I have a detailed price sheet describing how much the speaker parts cost. If you have any interest in building speakers, take a look the price sheet. After that, if you are still interested in building speakers and want to commit to buying a set of parts, let me know by this weekend. On Monday, I will order parts. Then, next Thursday, we will start with the first stage of the fabrication.

Sorry, but there will be no meeting tonight. Other matters have pushed to the top of my priority list.

An update about what we will do tonight: (1) talk a bit about how speakers work, (2) play around with some drivers, (3) discuss the particular set of speakers that we will build, including the cost (spoiler — about $50.), and (4) take orders for anyone that wants to make a set.
Next week, we will have an Arduino club meeting. After the usual first hour of chit-chat, we will set aside some time to start making the speakers. Or you can collect your parts and take them home to assemble on your own.

We will not have a club meeting this week. There are night exams, take-home exams, and class projects that must be tended to — everyone is too busy. And some people may have left town already. (tsk, tsk).
We will get our batteries re-charged during spring break and then pick up club activities afterwards. Next up is the building of the speakers in Audio Club. Check back here over break for info about the build and the costs, if you are interested in making a set.

When launching a rocket into space, aerospace engineers refer to a point in the trajectory where the rocket hits "Max-Q", which is when the rocket body experiences maximum external stresses. The same principle applies to people when a semester is launched — there comes a point of maximum stress. (Hopefully only one and hopefully not too much.) Anyway, I have reached my Q-max for this semester, meaning that I have dial back on some of what I am doing. Unfortunately, this usually means reducing club activities. So in order to keep from imploding and crashing, we will cancel the club meeting this week, with plans to pick up again next week. (Unless everyone is leaving town early.)
On top of my own personal whining, EE 285 has an exam tomorrow, and those folks should probably be studying, rather than goofing around with Arduinos.

Arduino club, Feb. 15, 8:00 p.m. in Coover 2011. We will look at using real-time clocks with Arduino, including the DS1307 RTC board from Adafruit and rolling your own version to include with your Bareduino

Audio club, Feb. 8, 8:00 p.m. in Coover 2011. We will have a look at the very simple GTDT audio amp. No kit available yet, but we will put one together soon. We will see if someone would be interested in making a PCB for this circuit.

Arduino club, Feb. 1, 8:00 p.m. in Coover 2011. We will be talking about — and making — "Bareduinos"
