Oscilloscope

[LaceSensor]

Anyone got any pros and cons for a cheap bit of fun like this?

Would it be useful for things like the BlueShift Chorus and Deluxe memory man calibration?

Only thing I'd worry about is it caps out at 200kHz. That is a bit low for some effects (The Flintlock flanger sweeps up to 2.6MHz for example), but for 30$ it might be a fun toy in any case.

I bought the DIY kit a while back. I've used it to test a couple fuzzes and a delay. It works pretty well. If it is the same kit I did just be ware that the power supply is center positive

I just built this one: https://www.amazon.com/gp/aw/d/B00C5TNXBW/ref=sxts_1?ie=UTF8&qid=1507770918&sr=1&pi=AC_SX236_SY340_FMwebp_QL65

and it's great. I added a BNC connector so I could use some decent probes.

I think it's really cool and at least opened the door into the oscilloscope world. I used it to scope my Gristleizer LFO and it worked awesome. I was going to try it on the DMM as well but haven't had the chance yet.

Again, just a nice way to get started with using a Scope IMO.

I think I'll have to get me one of these.

not to hijack this thread but I have been looking at this one (analog) scope on the local craigslist

Does anyone think it's worth it?

Id just hate to get it home and have it die after a couple of uses.

I've heard nothing but good things about Tektronix scopes.  You might try seeing if any other electronic-type forum
has advice.  AFAIK, Tektronix scopes are among the best.  I would seriously give this one a look.

A Tektronix analog oscilloscope is like the vintage Fender Precision Bass of oscilloscopes. There are other basses/oscilloscopes, and some have more knobs, but the P-bass/Tektronix will be classy, functional, and appropriate in any context.

That said, it is over 40 years old. It's working now, CRT looks good, the seller seems to know what they are doing, and it doesn't look like it's been dropped or abused. But there's always the possibility that a capacitor or transistor will die eventually. I think this one is old enough that it is all discrete and has no proprietary ICs or anything weird, so if something does go out you could likely repair it.

I have been planning to get one of the Jye-Tech mini oscilloscopes like at the beginning of the thread - I was thinking of the DSO150, which comes in a little case and has knobs rather than pushbuttons. But if I had a permanently set up workbench, I would be tempted to get an old Tektronix, partly just because I love that color blue and front panel so much.

I bought a Tektronix 2235 from eBay a year ago. They were meant to be repaired using tech available in the 1980s. The service manuals are available online, which is a good thing because an internal connector had come loose during shipping. You also need to study the operation because you'll have to set all the knobs, switches and levers manually instead of pushing an "Auto" button.

I only use the analog scope as my sanity check when I think my DSO is giving me strange results. Comparing the two scopes is like comparing a carbureted 1984 Ford Ranger to a 2017 Honda Accord Hybrid.

Compared to a DSO the Tek is HUGE so make sure you have plenty of bench space. It can't compare to the features available in a DSO, and the DSO can save configurations which means less knob turning and switch throwing.

I bought the cheapest Siglent digital scope on Amazon 3 years ago and have been completely satisfied with it, but I could probably get away with just the analog scope if necessary.

See, this is what I am conflicted with. Do I put $100 bucks into an old analog scope that could go belly up immediately or spend $250ish and just get a DSO like you mentioned.

I think the smart thing would be just to bite the bullet and just get a DSO.

this small cheap JYE scope has got me jonesing for a more advanced scope

Hey guys

I bought a cheap kit Oscilloscope from Amazon for £15 and built it up. Tested it on the VCO out of the Lovetone RingStinger. Definitely displaying the correct waveshapes!
This is the kit: https://www.amazon.co.uk/gp/product/B01LWK49W3/ref=s9u_simh_gw_i1?ie=UTF8&fpl=fresh&pd_rd_i=B01LWK49W3&pd_rd_r=f513d11e-b1ab-11e7-8b09-bd5b4c680d4e&pd_rd_w=amBh7&pd_rd_wg=PBbZz&pf_rd_m=A3P5ROKL5A1OLE&pf_rd_s=&pf_rd_r=VA2Y89G1RGDJBYSRCSJK&pf_rd_t=36701&pf_rd_p=187bec3b-0822-4044-bbe9-441718232b3f&pf_rd_i=desktop

For the money invested I am very happy with it. I fed the sine wave from the Ring Stinger into the Dimension C and although it looked a bit sketchy I was able to trim the waveform resulting at the test points. Im guessing the Ringstinger output wasnt exactly the same as the type requested for testing by the Aion instructions. But still, I was able to see the result of tweaking the trimmers, and settled at the most symmetrical spot. On testing, it sounds awesome (still); I think I had it tuned by ear quite nicely anyway.

YMMV. for the money its a fun kit!

I have two dirt cheap open-hardware scopes.
One is a single-channel, but has a display, and the other is two-channel and uses my Android phone as a display.  The latter fits in an Altoids Smalls tin.

I love these things mostly because they allow anyone to own a scope.  They are each infinitely better than only having a multimeter to measure with.

^^^ THIS. THIS. THIS.

[stringsthings]

I'm convinced that I need one of these inexpensive scopes.    (And it's DIY to boot!)

I put a link to the Kit that I ordered from Amazon below. It didn't come with a power supply so I bought one from BLMS and just reversed the positive and negative.
