So, I got this idea into my head (years back) where I wanted to hear soil, fungus, non-human sounds. I want to collaborate with these organisms and sounds. This started more ventures into electronics, and moooore workshops at Interaccess, creating sensors and later working with slime mould.
This week I got excited over a little circuit I stumbled upon off Andreas Siagian’s blog. Which is essentially this here,
So, based off of Andrea’s circuit I thought I would make one of my own, as well as draw up my own design. I biked over to Creatroninc, bought all the parts and made this:
Admittedly nervous about the surface mount soldering.. I put the little piggy together. Here are some images showing part of the process.
Parts listed on Github
CMOS cd4093, 100nf capacitor, Peizo buzzer, LED, 9v battery snap…
Ok so, I soldered everything down and……..
The LED works. Those 2 little pads in the upper right, when touched are suppose to make the oscillator oscillate – which is currently (haha) not happening. I have checked all connections, solder points = nada. So, I took this buzzer off to see if it even worked- it does. Soldered down another and still = nope. No sounds.
Do I lack capacitance?! What am I missing here?
Meanwhile, here is the image I altered to fit my drawing/traces.
Did I make my sensor pads too small?
Regardless, I learned a lot putting this together. 1. I need to make this work. 🙂
Anyone out there with any advice or suggestions as to what might be going wrong here, please comment below. Thanks for looking.
