Author [ORDER] ZeroScope, 6hp scope that's almost not even there
av500
ordering information below

ZeroScope, the 6hp dual channel oscilloscope for your Eurorack.

-10V to 10V, 100ms/div to 10 us/div. single, dual, X-Y, frequency measurement and tuner.







Ordering Information:

- complete ZeroScope module: €180 + shipping

- DIY PCB set with CPU soldered and programmed, including SMT headers to connect the PCBs, 2 plastic washers for the encoders, laser cut acrylic screen and matching screws in M2.5 and M3: €35 + shipping

payment via PayPal or EU bank transfer in Euro, please email me for orders at: vp (at) vpme (dot) de and please mention your MW nick so I can track who is who.

shipping for the PCB set is €7 worldwide as a registered letter, €5 inside Germany. shipping for the fully built module depends on where you are.



Mouser cart: http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=696b0 30965

missing are knobs and jacks, get them from the usual suspects. the encoders are D-type shafts, but push on round knobs should work too.

for the display, search eBay or Aliexpress for "0.96 OLED 128x64 SPI" and check that it is the white, 7 pin version, they should look like this:



make sure it's the single color WHITE (or BLUE) version, there are also some two color BLUE/YELLOW ones that you don't want.

Nice! I'm interested too

Really cool!

These are great and cheap displays, super crisp! There's four on the MIDIbox CV v2.

I wonder if the pins need a bit of insulation? Can't help but think they wouldn't be too happy with a stray cable carrying a 12V squarewave.

ah well, I like to live dangerously Dead Banana yes, might be good to add that, but I'll leave that as an exercise for the reader

Very cool!

Couple of suggestions: Find an OLED that's available widely (I.e. stocked by someone) That looks like the 1.3" one Mxmxmx used on the O_C and some other modules, impossible to find one now (I've been trying for the last few months). I would almost say find the bare displays and make your own PCBs for them, the few 1.3" ones out there now all have different pinouts. Wisechip makes the parts and you can usually source them through their dealers (just ordered some from First-components). If you can solder a 0603 chip, you can solder the display.

I would also never expose the display like that, the glass corners at the bottom are not supported by anything and snap easily. They contain the tiny wires in the black epoxy and if you break it, the display can go into the trash.

this is the 7-pin version of the SPI OLED displays that are all over eBay or Aliexpress:

http://www.ebay.com/itm/0-96-I2C-IIC-SPI-Serial-128X64-White-OLED-LCD- LED-Display-Module-for-Arduino-/172070682655

http://www.aliexpress.com/item/Free-Shipping-0-96-blue-0-96-inch-OLED- module-New-128X64-OLED-LCD-LED-Display/32595649930.html

there are also 6 pin SPI versions, we might offer both pinouts. the I2C version won't work at all as I2C is way too slow to update the display

in fact that display there I did solder to the carrier PCB since I bought them separately in China. the idea was to make a PCB that can be populated easily with a display that is available to order for the hobbyist.

well, that's only $5-7 down the trash, but point taken. we did not want to make the module wider and do some complex behind the panel mounting...

You could possibly do a 3d-printed little box that fits over the OLED & holding PCB - protecting the glass corners and hiding the pins. Possibly you'd need the module title text shifted slightly but otherwise could probably be done without changing anything much.

[disclosure - I know diddly about such things!]

yes, that's an option. I have another idea, but I need to try it out first.

Interesting!

this is not the final version, I think we will switch 0603 to 0805 to make it easier to solder. mayb also a little mounting PCB for jacks and encoders...

yes, 0805 instead of 0603 would be very much appreciated (the small sizes is what keeps me from doing the euclidean sequencer, 0603 is just too much).

Is the scope related to the Gabotronics Xprotolab? The latter is only $49 soldered and with display and everything. Won't fit in 6hp, but 8 hp should be fine.

no relation to the Xprotolab, this is a standalone development between a coworker and myself.

Im in, just so I can solder more SMD's! Also, AV I really like your cloth? covered cables. Where do you get the wire?

I buy these on AliExpress: http://s.aliexpress.com/jm2qEr67
(just an example)

then I cut them in half and solder a mono plug, connecting ground and ring from the stereo end to ground of the mono end. and I add about three layers of shrink tubing in the process. yields a dirt cheap 50cm cable that's very soft and doesn't curl around all over the place...

This looks really amazing! I'll be following its progress for sure.
spneca
I am interested.

Thanks AV. Slight hijack!

What Guage are those? I always have dreams of buying a couple rolls of these http://www.colorcord.com/collections/solid (which I have done, but for light fixtures in the house) but I figured 18g is a bit to thick for modular shenanigans.

The smallest I have been able to find is http://www.sundialwire.com/22-gauge.aspx 22g, bit it doesnt have the color range that I thinkwould be cool in organizing by length.

Ooo this one looks great. And DIY! Count me in!

one visit to the laser cutter later:



I do like the smell of burnt acrylic in the evening!

thumbs up was thinking of something like that. Could even use the M2 holes and save the top ones for case mounting.
sammy123
Interested for sure!!

the cable is about 2.5mm thick, I would guess around 2mm for the core without the braid, see here:

https://plus.google.com/u/0/+VladimirPantelic/posts/SgD1cvDei52

the actual cable strands are really thin and are like these headphone cables made from enameled copper wire.

these are the latest ones I ordered: http://www.aliexpress.com/item/Free-Shipping-7pcs-lot-3-5mm-Audio-Aux- Male-Stereo-Woven-Fabric-Braided-Cable-Pc-for/1921248033.html

one can also buy the sleeving, but I have no idea how easy that is to apply: http://www.aliexpress.com/item/Good-Quality-10M-2-5mm-Sheathing-Auto-W ire-Harnessing-Skyblue-Braided-Cable-Sleeving/32545634068.html
