Herctrap sent me this link yesterday. Based on the Burr Brown OPA2107 Operational Amplifier, this guy made a small audio amplifier without soldering the parts on a PCB. The soldering work is very nice and symmetrical, but i was not really amazed from this:
What i was really amazed of was the casing that he decided to make. Instead of making a plastic case, he made a mould and with a special transparent resin he casted the circuit! Excellent idea and perfect results!
The complete make is here. Thanks [Hercules]
