A cheap but very useful item of test equipment that would be an asset to any experimenter’s tool box. I picked up a BG7TBL Noise Source from ebay and built it into an enclosure.
There are reports that the PCB gets very hot during operation so mounted the entire PCB onto a piece of copper clad PCB which I also used to secure inside the enclosure.
Copper clad PCB to mount the noise source:
Thermal compound on the bottom of the noise source to allow heat to flow to the copper clad:
Noise source mounted to copper clad:
Assembly test fit inside case:
Power input, switch, LED and output:
Noise source connected to power input, switch and LED:
