  1. I hope this doesn't happen to me. Lesson learned. As a diver, I used to read all the things that killed people underwater. Now I read about all the people who get killed with electricity. It is dangerous!! Be careful!! I bought a pretty nice kit from Elenco. It is a well known adjustable power supply. Do I need one? No. Did I want to build one for the fun of it? Yes. I am OK at soldering not great. Pretty new. I took my sweet time and soldered it all together and everything looked to be in order. The guys with experience said, "I did it in one afternoon." Took me three days. Again, I took my time. I plugged it in and nothing happened. Fuse I forgot. Put the fuse it and it worked!! It lit up!! I was just getting ready to check the output and got up for a stretch and walked out of the lab. I was in at my kitchen table and heard this, "KaBoom." Oh that did not sound good. I am so glad I didn't have my face down in the power supply looking at it. A capacitor blew. I never did find out why. So of course I did what any science guy would do, I watched capacitors blow up in slow motion on Youtube. I learned something. They are built to blow up slowly. They have an X mark on the top to relieve pressure in case they overheat and then then just fizzle. Well I hate to tell you this but this capacitor did NOT fizzle. It blew up. I found the external casing and it was still totally intact. Still had the FAILED X on top and somehow, some way the capacitor failed to do what is was suppose to do and did not blow up the right way. Instead of a fizzle it was a freaking bomb. It was not like the little explosions I saw on the Youtube videos it was LOUD. I sent the unit back to Elenco, got refund, no questions asked. What caused this? I have no clue. I just can't even believe I would have put the capacitor in backwards. It must have been something else. Never did figure out what caused it. Some newbie bad wiring I guess. In conclusion to this huge tome of a response, I would like to say this. If you build a project using AC current, before you plug it in after the build, put on goggles and ear protection before you do so. Maybe even a bomb protection suit. Or plug it in outdoors and get away from it and watch it. Be very careful. Again, I'm glad my face was not down close to this capacitor when it blew.
  2. Greetings JColvin and thanks for the information. I am referring to the Analog Discovery 2 Getting Started page. I went thru all the steps and nothing happened. Tried to paste the link and this is what turned up: Analog Discovery 2 [Digilent Documentation] (digilentinc.com) On the Analog Discovery 2 page big green button says, "Getting Started." I went thru the steps and nothing happened. Also I had four messages. I went away from the page and your message and the other three were no where to be found when I went back. I spent the next 15 minutes looking around the site trying to find the missing four messages. My message area? Nothing now. All four of them vanished!! I deleted nothing. So then started searching on the area where I posted...could not find it. So I then searched my name and got back to my post. Where in the heck can you quickly go to see your posts and responding answers and why is the Diligent 2 not working in this simple introductory exercise? Confusing. Thanks JColvin.
  3. Greetings from Tennessee from a new member. Was excited to get my new Digilent Discovery 2. I read thru the first page of the book and loaded in the wave, kept the defaults, pressed the start button per instructions and it said now the wave is moving!! The wave didn't move. It sat there. I am an old geezer trying to learn the basics so I don't know how to troubleshoot this. Kind of a bummer the very first few steps didn't work. I was thinking maybe the wave is moving but so fast I can't see it? Not sure how to adjust or if it is just not moving for some reason. Click WaveGen, click arrow. Sounds simple. Nothing.
