Hi
Thought I'd post a few pics of recent projects--here we go:
No intention to bore, but first another GreenPre: green_pre.html
This are the boards I won on the "Thanksgiving donation" 2005--took a year to finish... I did apply some slight changes to the standard circuit. Works very well, a bit much hum though, will need to have another look at this. If I just wouldn't have messed up the level meter labeling. :evil:
Now an opamp test jig: opamp_test_jig.html
Allows me to quickly test opamps (discrete or IC) for various parameters (noise, stability, slew-rate, offset etc.). Very helpful for daily life!
Third a little headphone amplifier with a simple built-in mixer: headphone_amplifier.html
Perfect for basic personal monitoring. Cool in the lab for testing new gear too. No inside pics because it is a pain to open and close this beast.
Last but not least a 8 channel mic preamp with built-in (and bought in) AD: monte_zucchero.html
I designed this for a lab project at university, and my four student colleagues each built a unit. Big and heavy. But that's how we like it!
