> On the East coast you can be caught off guard by rain, snow, or really cold, windy weather. I’ve been caught a few times in the bad weather, to the point where I’ve started looking up the weather forecast before leaving the house. It's pretty humorous to read this perspective. The west coast must truly be as fantastic as advertised. > how do you debug hardware? One way is by using a multimeter. :( > A friend at the Recurse Center let me borrow Saleae’s logic analyzer Phew! Multimeter is not the way to go unless you really have no other option.

Are there any good low cost logic analyzers you know of? I've never had a big enough, or time dependent enough project to require anything more than a multimeter and patience, so I've not put the cash forward for a logic analyzer, or oscilloscope, or whatever. Not entirely sure what the difference is anyways...

  If you want to go for lowest cost possible, you can find tons of cheap hardware on AliExpress (search for "8ch logic analyzer", they go around 10 bucks). While these vendors usually just tell you to use Saleae's software, you can and should use the awesome open-source Sigrok (https://sigrok.org https://sigrok.org) tool, which supports these knockoff clones!

      I picked up one of those aliexpress "Saleae logic analyzers" a while back. It's obviously a knock-off, but it works really well, though I've never tried to use it at its advertised max supported frequency (2MHz), most of the stuff I do is < 1MHz.

    Oh, wow! Great tip. I found some vendors on Amazon selling the same thing for £10, which I guess is enough of a markup to make it worth it for the vendor, while still being crazy cheap to buy. Totally getting one of these.
