That is pretty fancy for a cable testing, I used this to measure cables you can find them off ebay since they are on backorder but it also helps with other things. Non-Invasive Current Sensor - 30A - SEN-11005 - SparkFun Electronics
Different purposes in this case. But valid point. This is a nice find for the price though. The “amp clamp”, that is.
Sidenote: I think we need an off topic section with a thread just for helpful links, tools. Etc.
I agree on the tools topic, its relevant especially tools that work well within the buspirate ecosystem. i have been taught that once i get far enough with my general boards then i will break out into something else. but its also super appealing with the plank system. for instance, i own a analog discovery, its nice i use it to read data coming from their Analog Discovery Audio Adapter+. that is what i use to read the data from those clamps. in fact using that when doing anything usb, you get interesting data. fingerprinting almost.
If anyone is looking for USB testing jigs, here’s a couple of low-priced items people might find useful.
- USB pcb adaptor - just an easy way to tap into a USB device at the hardware level. I’m not sure what happens at high speeds.
- Alvaro Prieto’s USB cable tester - this is just a cable continuity tester but the LED’s identify which lines are present. Since it’s open source, you can build your own or order it on Aliexpress. Here’s one link. I have mixed up cheap and expensive cables, and this helps me sort them by capability.
