MEP EP#276: Skippy DocumentationFake LM338 Voltage Regulators?
X-RAY results
Should we Xray legit LM137 and see if the XRAY matches?
SCPI or Standard Commands for Programmable Instruments
IEEE 488.2-1987
Send command strings over serial to configure and get results from test equipment
Test equipment mostly adhere to this with some weird gotchas
COM port snooper / sniffer?
Is there good software out there that can sniff the buffers / communication string between Windows and a hardware device?
Is bad documentation worse than no documentation?
“With no documentation you know immediately you're fucked.”
Bringing back the Tasty Chips segment - E-Z Hook Insulation Piercing Wire Clamp - 8507
Spring loaded clamp that has teeth
When you insert a wire the teeth slice into the insulation making contact
Datasheet specifications are interesting to say the least!
Max Current 1 AMP
Max Voltage 0 V ?!?
