    The Fathom-Sound Project

    Thanks Audioguru for the added schematic. I do have some bad news though. College has started back up for me. I also can't afford this project until I get things paid off and I get an actual job to pay for this hobby. With my current limitations I regret to say that I am putting this on a...

    The Fathom-Sound Project

    Here is the Schematic for week 3. Before anyone asks; I used Gimp photo editing to create the schematic. I basically took symbols off of schematics from the net and modded them with a pen tablet and then just copy and pasted the pieces together. For future reference I plan on doing three weeks...

    The Fathom-Sound Project

    I have been waiting on parts to come in, so there is a reason why I have not posted anything for today. Today being Tuesday I was hoping the parts would come in at noon. They did not arrive until 6pm and that really did not give me a lot of time to work with. I live in an apartment and I can't...

    The Fathom-Sound Project

    Thanks Audioguru, I will redraw the schematics and make the corrections. I did not think the transistors needed it if the voltage stays around 5volts and the touch gap would be like a half centimeter apart. Might be good idea to include it in the long run just in case. . As for the mixer; I must...

    The Fathom-Sound Project

    Week 3 of Project In our previous experiments we adjusted resistance to modify the current. Our previous experiment was to see if we could not make an oscillator have an octave of buttons. All of which were a half step apart. Although we can play all the notes in the octave at any given time, we...

    DIY conventions?

    Not being mean, but how does one start a conversation if not for asking a question? I was looking for peoples experiences as well as general information.

    DIY conventions?

    I went to Bronycon in Baltimore a couple of times. Unfortunately 2019 might be their last year. I do have more interest in DIY electronics than MLP though. Are there conventions or fairs out there where people get together to show off their projects? I would like to know since I am doing the...

    The Fathom-Sound Project

    It kind of depends on the capacitor. Right now I am testing a 0.1 micro-farad capacitor, a 100k (R1) and a range of resistors from 2.5K to 35K. That makes up an octave. This produces a whistle sound sound. When I record samples in Audacity it looks like a sign wave. I am still saving up for an...

    The Fathom-Sound Project

    2nd Week of Project A realistic approach Overview First week for sure was for trial and error. I learned a lot about how to keep everything consistent. I also learned that keeping a fresh battery in my multi-meter is crucial for making proper measurements. I will be looking into buying a bench...

    The Fathom-Sound Project

    An alternative & The analysis You probably looked at the two parts of the previous circuit and thought I was crazy. Well I realize I made one mistake. You still want to try many different options, but taking measurements with a voltage divider might not be the best idea. I will be changing this...

    Booting Raspberry Pi 3 B+ from USB Drive

    Thanks Totalmedtech. Thats what I was looking for. I kind of had an idea on how, but I did not know if there where problems. At least since the B+ model was still relatively new.

    The Fathom-Sound Project

    Introduction The primary goal of this project is to document my journey in building a synth. I have not seen a whole lot of midi controlled synths projects out there. At least not one that documents both the progress and the failures encountered along the way. I always wanted to build...

    Booting Raspberry Pi 3 B+ from USB Drive

    Last I heard there was something new on the board that prevented USB from being bootable. Has anyone been able to find a work around for this yet? I read about this idea from another forum. How is this done anyway?

    I will respect your decision Davenn. Even though I don't agree I find it important to maintain order. Unlike some social media places.
