Looks like I have to do a FAQ as this video has been so popular: 1) No Jaycar do not sell this scope for $5, you can't but it anywhere. I got it at a clearance dumpster sale. 2) No I could not buy two of them to swap parts, I was very lucky to get the last one. A minute or two later and it would have been gone. 3) No I cannot ship it to country X. International postage is expensive, so I will give it away to a local kid here in Australia if it gets fixed. I don't care if you think that's unfair.
That was my thought too, looks like one of the cables is for the 4 pin PoE header. The three holes in the back of the case, with the silver standoffs, would be the board location.
11:20 It’s for a raspberry pi! Hence the 5V supply, Hdmi Passthrough cable, 40 pin gpio connector and the chassis cutout. It might be a bit of work but have a look at running retropie or retroarch on it.
@EEVblog2 Some punks with arcades have complete build images on the internet. The legality of most builds should be questioned. You can install the buttons using GPIOnext (refer to the XC9062 manual).
The cheap DIGITECH/Hantek PC scopes work really great with the OpenHantek software! I use mine almost daily on my Windows machine and am really happy with it.
What kind of isolation do they have between the sensing side and the computer, any chance of blowing up your PC? Ideally you’d have opto-isolation at or just before the USB, or maybe after the ADC. I’d also like to know what kind of front-end protection they have for the scope itself.
@asdad asdasd Yeah like every hobbist ow 5 figure scope multimeter and every other lab equipment which they use couple of times in year. Very expensive scopes are used daily in R&D labs.
@asdad asdasd I respectfully disagree. The cheap one has many advantages ...you can use it in the rain, loan it out or test something dubious without fear of loosing five figures.
I also have one, one thing that annoys me is that they didn't implement the bode plot like they (falsely) advertised. It really just shows you the gain and phase shift at a specific frequency, not a plot.
We use those USB scopes all the time in custom test jig setups and to digitize analog equipment 40-80 MS/s for $40-60 with a full frontend and reasonably accurate, can't go wrong! as far as software goes, some sigrok modules exist but the protocol is extremely simple
The broken scope looks exactly like the Hantek one I have: DSO4102 - and yes, you can use the sig-gen and the scope at the same time, the button switches the UI. (EDIT: typed faster than you talked :D )
Also to verify, the scope appears to have 'booted up' so a new screen will fix it if compatible. You can use the DSO and the signal generator - but you switch screens to view the output waveform of the generator when setting it... Apparently it uses the front USB like it does the SD-card slot, you can save waveform captures as csv. The rear one interfaces with a computer, according to the manual. I think you can bring up the display... I gotta play around with my one a bit more - good to know about that coin-cell in there, something to replace every few years...
Had that same scope, with the same problem. Found the -7 volt supply was failing and going high voltage. When I found it, and replaced the regulator, it had destroyed the chip used for Sync. Scope worked, but had no working sync. That part was unobtanium.. Gave the scope away. Sorry no longer have it to send you the screen. Be sure to check that -7 volt regulator.
You can control the screenwrecked oscilloscope/sig-gen from the USB as well. Specs for sig-gen was written on screen under the scope specs: Scope: 100 MHz, 1G Sa/s Gen: 250MHz, 200M Sa/s
That generic screen is actually not all compatible with others, I have some of them and it actually flipped or only display the full image on 1 small corner and just like.. duplicate it for the rest of the screen
If the Digitech USB scopes are re-badged Hanteks, the use a Cirrus Logic PSoC and a couple of AD converter ICs. Pretty simple in terms of major component count, but quite usable for basic scoping.
My impression of the Hantek USB scopes isn't the best, especially the software (didn't someone make a better replacement free online?), but 20MHz can be way more than you need for many jobs and when you need a scope a low end one can be way better than none. We can't all work in the MHz range, some signals only go to kHz. ;) Great idea for a giveaway!
It is nice that you took from the Coulomb rich to give to the electron poor. Hopefully that scope gets a working screen. I guess the "easy repair" stuff went quick.
Finally it seems you took some of those to test!!!! I hope.. I will already give a like for the pleasure of listening you say Hantek, because I hope to see you reviewing DSO4102C in my lifetime.. 4:00 well I have one in front of me now and it really seems to be the same.
Even if the screen isn't working, you can plug in the USB port and see if you can control it and get measurements off of it. Then you'll be able to see if the rest of it is working before going to lengths to repair it.
Edit: have one of those panels sitting in a cupboard here somewhere Must be nice being able to go to things like this. I live in rural SA..... Not much going on around here obviously.
I honestly would be happy to have any oscilloscope right now... My Rigol firmware just died on me and I'm outta budget to buy another, even used one. ((
You can buy a board for that arcade stick for about £40....they are pretty good for the money, mine does ps1 and some Dreamcast and a couple of n64 games. It's a hell of a thing to get out when you get back from the pub emulation is fine enough for oldschool arcade beatemups
I hope you bagged some components. Hopefully they had some semiconductors and LED devices too. The 16x2 LCD displays can come in handy for the not-so-demanding microcontroller projects too.
Would really love to see full investigation and repair on the Hantek 4000c scope that you got with that display damage, especially if there's anything wrong with it besides display. Hey a Pandora without a PCB is a decent catch too. Big metal console with all the controls on it, and like sure they're your standard knockoff grade, but arcade style controllers for home consoles, when those were a thing, in the 16bit era, were often worse, much much worse. That power amp is MUCH nicer than Dynavox miniamps that you could get back here a while back as well. USB scopes - nice as well, for sure will help someone along.
A number of those game boxes use a Pandora Box game controller. I would guess that it would either directly connect or be easy to adapt to one of these controllers. I just checked, you would need an adapter or cut the cables.
Your lucky, even with the broken screen if that item was in the usa, that turd would of been listed on eBay for like $200. Deals like that are nearly impossible to find in the usa
'Oly sheet! I have the model just under this, it's a 70MHz jobby - but identical interface etc. I got mine for 100x the price a few years back - though I had a need for a signal generator, and the impulse capture capability of a DSO. Until this, my two analogue scopes were all the rage - 20MHz tops, and one recently crapped itself!

I have two tektronics CRO's 20 and 200Mhz, but I've never had the money for a waveform generator. Always having to improvise/create test signals. A USB arbitrary wave gen would be a MAJOR upgrade to my bench. Even if it is only 20mhz.
I'm really jealous. It wouldn't be worth it to fly there and it would cost an arm and a leg to ship that stuff back to the USA. I'm rather suspicious when big company with more resources than I have decides to dump stuff for pennies on the dollar. I would think that they took a swing at fixing the items and found it wasn't economically reasonable. On the other hand, if you can get the parts needed and you are doing this for fun (you don't put a value on your time) then I suppose these items can be worth while.
The Hantek USB scopes are no good. But I do have a Hantek 4000 series 100Mhz 4 channel. It's prefect for me :) used it when building and debugging TTL logic computers.
its a DSO4104B, I brought it direct from their china factory, Fedex delivered it in like 3 days :D and the sneaky people labeled it as $75 not 400ish so didn't have to pay import either haha

Digitech is a well-known name in the world of digital sound processors, effect pedals etc. but the logo is different, it's just a name coincidence, not the same brand. More of that screen film peel ASMR content, please! Good luck with looking for the screen, it'd be fun to get it to work. Go for the HGM Picade retrofit, the box is worth it! I like the amp's metal enclosure and innards too. Take a closer look at the power transformer's power rating; seems small-ish for the 2x120W declared output power. I'd replace the filter caps with 2x10000uF. BTW, as far as power is concerned... I'd like to hook the thing up to a dummy load and do some measurements.

Dave, use a raspberry pi, with retropi the holes on the back shouls align with usb and lan on the pi as well as the holes
for mounting

That arcade joystick thing definitley takes a Raspberry Pi.
Maybe the usb scope software can be used on the cracked display unit.
Possible!
You're so lucky to be able to access these. Where I live there's nothing like it.
Yep, it's exactly the same scope as my Hantek DSO4102C. You got an absolute bargain. Pretty sure I paid $300-$400 for mine a couple of years ago👍🇦🇺

Oh my, that power amplifier has motorized knob 😍
those 13.8v 40a power supplies are for ham radios but also make great car battery chargers - could sell those dead easy
For the USB scopes, there's open source OpenHantek software that works. The included software doesn't work
You can use it USB style in conjunction with a PC And it is indeed a Hantek 4000C series...
I think that's a RetroPi arcade enclosure. You drop a raspberry pi in with a certain sd card image and it emulates a bunch of different stuff.
Yep, need to find the image. Don't want to have to cobble it together manually.
Jamma? That's a 40-pin socket that fits on a RaspberryPi. The empty holes on the back also point to it as needing an RPi.
