Next meeting

Topic: Bareduino build

Where: 3043 Coover and 2011 Coover

When: Tues, Nov. 27, 2018 at 8:00 p.m.

No meeting on Nov. 13. Everybody (including me) is too busy heading up to Thanksgiving break.

On the 27th, we will build the infamous "Bareduino" – an Arduino without all the frills. It's fun, it's easy, and knowing how to "roll your own" expands the possibilities for embedded systems projects.

We will spend a few minutes discussing what is needed for the build, and then retire to the lab to commence with the soldering.

Kits will be available. The cost will be less than $10. (I'll have an exact amount once I have checked current prices.) If you think you will want a kit, be sure to let me know prior to the meeting, via email or slack.

Sometime over the next two weeks, we can decide if we would like to have one more Audio club meeting before the end of the semstester. (It would have to be during dead week.)

Info and Updates

Nov. 13

No meeting this week.

Nov. 6 (past meeting announcement)

Topic: Exploration of Audio Synthesizer

Where: 3043 Coover

When: Tues, Nov. 6, 2018 at 8:00 p.m.

This is a special Audio Club meeting. Tim Lindquist will be presenting the project that he completed for his M.S. degree. He will discuss various audio synthesis techniques and then describe and demo the hybrid synthesizer that he built from scratch. It will be awesome! You should try to attend.

Oct. 30 (past meeting announcement)

Topic: The Altoids amp build

Where: 2011 Coover (Note the room change!)

When: Tues, Oct. 30, 2018 at 8:00 p.m.

What to bring: If you want to build the amp, bring $13 for the kit, an empty Altoids candy tin, 2 9-V batteries, and your 201/230 lab tools. You might also stick an audio cable in your bag as well, although I will have some spares that you use tonight. If you want to just come hang out and shoot the s__t, that's fine, too.

Here is the procedure for building the altoids amp. These instructions will be updated before we meet tonight.

I think I have enough parts for 10 kits. I've heard from 3 or 4 people at this point. If you want to reserve a kit, send me an email (if you haven't already) or contact me via Slack. Otherwise, it is first come, first served.

Note: I will accept a short-term IOU if you want to build an amp but are short on cash tonight. I can also do ApplePay, if you are into that sort of thing.

We canceled our soldering session that was planned for a few weeks ago. If you haven't soldered before, you will need to learn some of the basics before you can put assemble the Altoids amp. Fortunately, the kit includes a printed circuit board, which makes the soldering much easier. However, you should note that ETG is putting on a soldering tutorial tonight from 6:00 till 9:00 in the TLA (I think). So you still have a chance to get some formal instruction and practice, if you want. In principle, you could go to the ETG lesson and then cut out a bit early to come up to the 2011 lab and use what you just learned to put together the Altoids amp. But that might be too much fun for one night.

Oct. 23

At this point, I have only two confirmations for people who wanted to do the session tonight. I would like to have some more in order to make the whole endeavor worthwhile. So let me know if you if you’ll be coming. And even if you’re not, pass the word along to your friends who might be interested.

I don’t mind doing sessions for small groups, but there is “more bang for the buck” if we can have at least a half dozen people or so. Also, I don’t mind canceling these meetings if there is not enough interest. (It is impossible to hurt my feelings, so that is not a concern.) If people are not interested in the topics, are simply too busy, or already have all the skills they think they need, that is fine by me.

Oct. 23 (past meeting announcement)

Topic: Arduino programming basics

Where: 3043 Coover Addition (3rd floor conference room)

When: Tues, Oct. 23, 2018 at 8:00 p.m.

What to bring: Your Arduino, an A-to-B USB cable, and your laptop for interfacing. (There will be a few spare Arduinos available to use if you don't have one yet.)

If you plan to attend, please send me an email or contact me on Slack to let me know. (If there aren’t enough people interested in this introductory stuff, we can skip the meeting.) Even though the programming activity is meant for neophytes, you hardened veterans are definitely welcome to attend to provide advice and tell war stories.

Oct. 16 (past meeting announcement)

Topic: Designing speakers

Nick will be talking about speaker design. This will be our first step toward designing our "club" sub-woofer.

Where: 3043 Coover Addition (3rd floor conference room)

When: Tues, Oct. 16, 2018 at 8:00 p.m.

Oct. 9 (meeting was canceled).

Topic: How to solder
Where: 3043 Coover Addition (3rd floor conference room) and 2011 Coover
When: Tues, Oct. 9, 2018 at 8:00 p.m.

We will have a short lesson on the basics of soldering and then retire to the lab to try soldering together a small circuit that uses a 555 timer to blink some LEDs.

If you would like to partake, let GTuttle know (via email or Slack) and then show up at 8:00. (We need to know how many people are participating so that we bring enough parts for everyone.) The presentation will be less than 30 minutes and then we will have an hour or so to practice. Things to bring: Some of your EE 201 lab kit tools — needle-nose pliers, wire cutter, wire stripper, and small screw driver (for adjusting the potentiometer) – and $4 to pay for the parts.
