ISU Audio and Arduino Clubs

Once again, PCBs from JLCPCB will not be delivered in time for a planned build session. So we will adjust the schedule to adapt.
- Oct 20 — Discussion session at 5:30 p.m. in 3043 Coover. We will describe how speakers work and discuss some of the aspects of designing a complete speaker. Then we will describe the desktop speaker project that and lay out the plan for building them. Finally, we will talk about the Temp&Time Arduino project.
- Oct 27 — Build session at 5:30 p.m. in 2011 Coover. We will build the GTDT amp and the Cyduino.
- The remaining meetings will proceed as originally scheduled.
The LM2594 switching-mode controller chips for the DC Supply project have arrived, and anyone who needs one can pick it up at the meeting. Of course, they can be picke up at any later meeting if that is more convenient.
We will have a build session this week: Monday at 5:30 p.m. in 2011 Coover (the lab room). We have the boards and (most of) the parts for the DC-Supply project. Many people are interested in building this one. Also, we have everything needed for the battery checker project that several people have signed up for. Build instructions for both projects can be accessed using the Projects link above. And there will be plenty of help available for anyone needing some assistance. If anyone needs more time to continue on the earlier projects( Altoids amp and Resisto-meter), that's fine, too.
Coming up on Monday, Oct 20, we will have another build session. There will be two new projects available (GTDT amp and Cyduino). Of course, people can continue working on any of the earlier projects.
The PCBs for the DC power supply and battery checker projects will not arrive in time for the planned build session on Oct. 6. (The JLCPCB factory in China closed from Oct 1 - Oct 3 for the "National Day of the People's Republic of China" and the associated "Golden Week celebrations.") Consequently, we need to adjust the schedule by flip-flopping weeks 4 and 5.
So, on Oct 6, we will have class-room discussion about:
- some "teach-yourself" Arduino tutorials
- the general characteristics of audio systems
- properties of amplifiers, and
- description of the GTDT and Cyduino projects
Then, on Oct 13, we will have the build session for the DC power supply and battery checker projects. Following that, on Oct 20, we will be back on the original schedule, and we will build the GTDT amp and/or the Cyduino.

Reminder: The next meeting will be on Monday, Sep 22 at 5:30 p.m. We will working on building the Altoids headphone amp or the "resistometer". If you signed up for one of the projects, you will have a couple of hours to work on soldering together the circuit. If you haven't soldered before, there will be experienced club members on held to help you.

The web site for the clubs has been updated. More material will be added in the next few days and weeks as the semester progresses. In particular, there a description of the Altoids headphone amp project and build instructions. Similar information for the "resistometer" will be forthcoming. Take a look around. Let me know if you have questions or see something that doesn't look quite right.

Club meetings are on Mondays at 5:30 p.m. Duration is between one and two hourse, depending on what is happening that week. There will be 10 meetings total during Fall semester. Five will be discussion meetings, which are held in the 3043 Coover conference room. The other five are "build" sessions, which are held in the 2011 Coover lab room.

Editorial Note: In the past, Audio Club and Arduino Club information was split between two separate websites. That was awkward and confusing. Now information for both clubs will be on one site. On the schedule page (link in the menu above) are brief descriptions of the weekly activities for Fall semester. More details regarding classroom discussions, projects, and other club activities will be added in the coming days as the two former web sites are restructured into one.
