Just out of curiosity - is there a viable USB oscilloscope for $35 out there? I'd love to have a scope for a few projects but I'm hesitant to jump right into one of the $300+ ones.
- lpasselin 6y agoYes. I got one from AliExpress for 30$ including the 12V psu. It works fine if you aren't working with super high frequencies. I use it mostly as a voltmeter.
- cushychicken 6y agoI've never found a USB scope that I particularly liked working with. Gauging from the job postings on their website, I have a hunch/dream that the folks at Saleae are cooking a decent USB scope up as their next product offering. Would love it if they did. Saleae's Logic Pro 16 is without a doubt the best designed EE tool I've ever used.
- Junk_Collector 6y agoFor $35 most of the scope you see are going to be repurposed sound card chips acting as a digitizer. They work ok-ish but you get what you pay for. My big problem with a USB oscilloscope is that they are only ground referenced through the USB ground to your computer and if you measure something with a different ground reference you can blow up the USB port on your computer.
