Ryan Leggett’s Work Log

Week of 9/9/24 . Project update 1.

To Do list for the next week:

1. Research everything since I am new and still need to learn about synthesizers
   • MIDI compatibility and find what could work for our synthesizer
   • Envelope and how we will use it for our design
   • Low pass filters and what we will use in our design
   • DAC and how it is used in our synthesizer
2. Help make our MIDI input parts list and get the parts ordered so that we can start working on our simplified synthesizer
3. Connect our Arduino and MIDI keyboard to a oscilloscope and make sure we are able to produce square waves using the keyboard

Week of 9/22/24

I completed almost everything that I had on my to do list.

We were able to produce waveforms when we connected our Arduino and we switched to a Teensy as well and were still able to get the waveforms correct. I researched many things and I have more knowledge now so that I might be able to help with more things. We were able to get the majority of our parts ordered and we are now just waiting on a couple to get delivered. Nothing will get moved to my to do list this week since we have completed everything.

To Do List for the next week:

1. Receive our ordered parts and make sure they are all correct and we can use them.
2. Work on the CDR
   • Get the template and get together as a team to work on it
   • Work on the slides for one of the problems we have faced
3. Research and figure out how to connect the envelope and if it will work for what we are making

Week of 9/29/24

I was almost able to complete everything on the to do list. We received all of our parts but our filter so we were unable to test that and experiment with how we would want to use it. We received the rest of our parts though so we were able to experiment with the envelope and figure out that it should work right now for our needs.

I worked on the CDR during a meeting time with the team and we were able to get a lot of it done. We weren’t able to finish it completely so that will need to be moved to next weeks to do list.

To Do List for the next week:

1. Finish up the CDR
   • Complete the remaining slides we have left and I need to finish the slides I’m doing
   • Present the CDR during our allotted time
2. Hopefully receive our IC filter so we can start using that in the circuits we are building
3. Start making a rough layout of how we want all our boards and Teensy connected (model in multisim)
