    Fizzle Loop Synth - 555 Timer

    3D printed box and knobs. I added a volume control on the right side so the kids would not drive Nana completely crazy. They love playing with it! And, by the by - I figured out the 'add a capacitor' hook up - just took a bit of research reading up on circuitry whys and hows. I figure you surmised that's what I (or anybody else here) would - and/or should - do.

    Waiting to see reply to Maurilio. Some of the instructions do not jive with the schematic. I'm going out on a limb and assuming that the schematic is correct - until otherwise advised.I made your fizzle synth - the kids love it - made the box and knobs on my 3D printer.Working on learning KiCad - so using this as an exercise in learning to create a printed circuit board. fun so far!

    OK - so I'm going to apologize for sounding like a whiner here - but you can't just say 'install a 100µf capacitor'. Can you please at least give a brief explanation of which way the polarity goes and what wires get connected??

    So I have already successfully loaded the main programs on the LCD and the ATtiny85. I guess that means I don't really need to mess with the others.

    Thanks for the quick response. I'm a newbie at electronic stuff - but I learn fast. Thanks for the explanation on the pots. For the 'add a 100µf capacitor' I have questions. Does it go in the + or GND line? Which direction is the polarity of the capacitor? (i don't know enough yet to just 'know' how to install a capacitor, I need to see it in a schematic)

    So, I made this thing and its really quite cool to play with (and really quite annoying to some - which is actually quite hilarious!) You mentioned an out-put jack, but none is shown on the schematics. Am I correct in supposing that out-put should jump off of the leads to the speaker? (I am new at electronics and still have a lot to learn) I am a little bit confused with the wiring of the pots - the schematic only shows 2 connections, but the pot has 3 pins. Do you have a close up photo of how the pots get wired up?

    The Blink example and the Enroll example will not verify on my IDE.

    RE: my question on step 7 from 4 weeks ago - I am now able to, and have loaded the ATtiny85, and have loaded the Final Code for the LCD unit. So its not a hardware problem on my end - I suspect a software/sketch problem??

    I have tested the LCD with my Arduino Uno board and it works nicely. I have downloaded the files for the AT Tiny85 but can not load them onto the chip. I keep getting this error message from IDE: Invalid library found in C:\Users\user11\Documents\Arduino\libraries\ArduinoProjectHandbook_CodeandLibraries:

    trying to figure out how the two circuits get wired/work together with two different power sources. do you have one diagram showing both circuits and the connection between the two circuits?

    Thanks for the quick response EGP. Good explanation - I 'get it' now!

    again - thanks for the reply - but now its more complicated and difficult to understand. there is already resistors connected to FPS 2. your sketch was nice - but I need to see a complete corrected schematic diagram in order to understand this.

    thanks 4 the reply - your drawing is perfectly fine. you are showing the connection to FPS pin 1. the instructable says FPS pin two (which is connected to D11 with a 560 Ω resistor) is the note in the instructable incorrect?
