# Epoxy transducer
### TX:
Driven directly through the epoxed transducer desoldered from the hc-sr04
- Amplitude: 12Vpp
- Frequency: 58kHz
- Number of cycles in burst: 3
- Frequency of burst: 30Hz
### RX:
The signal from the other desoldered transducer
Amplified by 100 with two inverting offset amplifiers
### Results
#### Top of bucket

The diverging at the end might be me not being able to reach
the bottom of the bucket so good.
