content: Hi all,Since I got my new Keysight MSO, I have found that I haven't touched my logic analyser. It is no good collecting dust on a shelf, so I figure I'll give it to someone who will use it.It is a Saleae Logic Pro 8. You can read about it here:https://www.saleae.com/Not anything amazing in terms of performance, but it is good for someone learning about digital.Be warned that you need a USB-3 computer to run it.Same conditions as my scope giveaway last year.If you want this thing, then post in this thread what you want to use it for and anything else that you think might distinguish you.I will ship it to you for nothing so long as you don't live at the north pole, the ISS or something.Important:Offer is only open to those from a non first-world country.If there are several people who want it, I'll pick one somehow. You have 3 days from when this post was posted. Many thanks to posters in this thread. The Saleae has a new home now.Thanks,R

content: Hello Dubbie, thanks for the giveaway!I'm a newbie in the electronics design thing but I've been working on a level sensor for electronic waste bins. Already designed the board on KiCad and put everything together, but I have no test gear to debug the digital interfaces and I've been struggling with some intermittent errors (sometimes the ultrasonic sensor will measure a value much lower than the real one). I think that logic analyzer would help me out with this and other future debugging needsAgain, thanks for giving away your test gear, thats very generous of you.Caio

content: Oh nice one! That actually a pretty capable analyzer.I have the first one that Saleae made but that one is quite slow for modern electronics so i later got a clone of a faster one and that one worked great. Tho the clone died on me out of the blue.For someone just starting out this is going to be a very valuable tool.

content: Hello, i'm a 21 yo Electronics and computer Engineer from Athens, Greece (National Technical University of Athens), I'd love to have the logic analyser as i have started my first OSH project,https://hackaday.io/project/19134-ardugen, which uses chips with SPI and I2C interfaces (especially the main one AD9102), so the LA will be very useful, debugging my (probably plenty) mistakes. Here you can also see my first prototype in KiCAD. I had a passion for electronics since i was in junior high school, (my first DMM an ex330 which is still my main one) but only recently, when i have started working part time, i have managed to buy some more test equipment.One final word though,which is irrelevant whether i will be picked or not,Congratulations on your generosity and if there were more people like you the world would be a better placeCheers,Evangelos Petrongonas

content: Let me throw my hat in the ring as well. I live in India and work on medical electronics. I have access to a good oscilloscope and multimeter through work + goodwill, but no logic analyzer. I also own old analog scopes and a recently acquired portable oscilloscope, and I have used these for rudimentary digital debugging, but with these tools, most things take a lot of time and some are downright impossible. A logic analyzer would be useful. Most recently, I felt the need for it when I was using an AD5933 (interesting IC for impedance measurement) and was getting garbage data out of it because of I2C issues.I share my equipment with many friends, even some start-ups. I am also involved with a local hacker-space type of facility, and if I end up being the lucky winner, this LA will likely be used by many people.

content: Thanks for the posts everyone.3 extremely eligible requests in there.I've got a very busy day at work today, so I won't get a chance to post the winner till later today.Thanks again to everyone.

content: Sorry for the late response. I've had a very busy day and just finished work. After much thought, I like the idea of djnz sharing the tool with others. The other responses were extremely worthy as well, and I am sorry I can't help with those as well! Thanks guys for participating, and good luck with your projects. djnz, please pm me your shipping details and I'll get the Saleae sent out to you.Sent from my phone using Tapatalk

content: Wow, thanks a lot! I will see to it that it is put to good use, and when I outgrow it, I will hand it down (free) to someone else who could use it.Thanks a lot for your generosity!

The specs say it can go higher, but that needs USB 3.0! Alas my X220 laptop from 2012 does not have any USB 3.0. But it does have an ExpressCard slot. Time to hit eBay for a USB 3.0 ExpressCard. Found this one:Alt link:https://s30.postimg.org/4usehfwq9/expresscard.jpgIt was delivered within a week. Now we can get the full 500 MHz digital:Alt link:https://s30.postimg.org/xtcv40dip/capture2_usb3.pngAlt link:https://s30.postimg.org/qrexht9wx/capture3_usb3.pngAwesome! Thanks Dubbie!
