Hi!

Do You use homebrewered (DIY, selfmade) gear now? Show it!

This  is an 4 channel amplifier I made for special testing purposes






Here's an debug adapter for very special purposes:

And a somewhat larger 3 channel amplifier I made for no particular purpose:

Ok, I'll bite  :)  My isolation transformer:



exe:
These are power supplies I use. The transparent one is a kit. The lunch box is the famous "0-30V 0-3A" kit (it can't really handle big currents due to inefficient cooling, but good-enough as an aux supply for biasing). The "big" white box is a custom design 0.7-15V 0-1A based on lt3080. All three are linear.

RFDUK:
Made a low cost calibrated noise source for noise figure measurement of low noise amplifiers 8 years ago. Friends saw it and wanted one so I've sold quite a few now. Hope it qualifies for this thread   :-//

Achieved a temp coefficient of just 0.03dB/degree C and short term and long term stability have proved to be excellent. Covers 10 MHz through 3400 MHz.
