I am stuffing the boards, but I don't have 7805, I do have 78L05 can I use these? Those boards will not pull more than 100mA right? Any specific reason for chosing 7805?

I will need to "twisterise" the legs if using 78l05 because the pinout is different.

I have created some 4HP Eurorack front panels for this project:

Posted Image, might have been reduced in size. Click Image to view fullscreen.

Read all about it, here: http://glitched.org/up/2010/12/modular-front-panels-by-glitched/

The longer version with higher resolution photos, is here: http://glitched.org/up/eurorack-front-panels-by-glitched/

So as to not hijack this thread, I will create a new one on this forum when I've figured out the best way to sell them. In the meantime, keep an eye on http://glitched.org/up !

Those look awesome, Glitched.

Jarno, a 78l05 will work fine. I had no specific reason for using a 7805 other than having a lot of them on hand.

Thanks, Boogdish!
Let me know which one you want, if you want one. I sent you an email, too.

Information coming soon.

Regards,

Do you need a front panel for your dual quantizer?
Well, take a look at this post, which contains tons of pictures and the creative process:

http://glitched.org/up/eurorack-front-panels-by-glitched/

After you've read that and decided that you potentially want one, read this post on how to get it (this link is in the article, too):

http://glitched.org/up/2011/01/how-to-get-the-eurorack-front-panels-by-glitched/

The abbreviated version:

0) Check which designs are available by viewing this spreadsheet:

http://bit.ly/eJPmvN

1) Go to the “front panel request form,” here:

http://glitched.org/up/front-panel-request-form/

2) Enter your details.

3) In the message body state the following:

a) Which panel(s) you’re interested in. (Example: QUANT-white/black/raster.)
b) Quantity (list a number for each style if multiple panels were chosen)
c) Paypal address (if different from contact email address)
d) Your country. I’m located in the US, but will ship internationally.
e) Any additional notes or requests.

4) Hit “submit”.

Now, this is important: unless the panel is currently in stock, the steps above are only to declare your interest in these panels; there is no obligation to buy and your paypal address will only be used at the final step, when I need to initiate the production run.

If I have the panel that you want on-hand (again, see the spreadsheet), I will send you an invoice right away and you can pay me.

If I receive interest for more than 5 panels, I will be able to initiate production (great!) and will then send you an invoice for the total, to your paypal address. I will also notify you of the payment cut-off date. If I don’t receive money by that date, you will not receive a panel (but there may be a couple extras, after everyone has gotten theirs).

Once the order is placed, it can take anywhere from 2-3 weeks be produced and get to me. I take them, paint them, and pack them up. This probably won’t take more than two days. After that, it’s time to ship!

Thanks for the great project, Michael!

FYI: The QUANT panels have 7mm holes for the pot and 6mm holes for the jacks. I used the alpha pots recommended by the project documentation and Kobiconn jacks (16PJ138, at mouser).

Hi Glitched, request sent.

Thanks for the service as I like colour in my rack.

Great!

Just a couple more left in stock. After that, there'll be a waiting list (check the link), but there will be more choices.

Hey everybody, I've got a new layout for this project which I was waiting to announce when I sold out of the previous batch.

The new layout has mounting holes for people not wanting to use pc mounted pots and instead of standard chips and octave chips there will be one version of the chip and an onboard jumper to determine which set of lookup tables the chip uses. This means you can also use a switch to change between the two.

I'll have documentation for the new layout when the boards become available.

Woo hoo! Mounting holes and switchable octave mode...sweet! I'll be ready to get a few more once they're available. The 4 I got before were supposed to be for some sequencers I have in my backlog, but looks like I'm going to be using 2 of them before that on an S&H/LFO panel.

More Quantizers = More Goodness!

Hi Glitched,

Front panel arrived here in the UK. Sincere thanks for a great service.

Cheers

Hey, that's really great! So quick, too!

Just a reminder, there are still a couple left.

for god's sake, somebody please make a diy quantizer with 12 switches to manually set your own scales! Razz

You have the Moon 565 controller in mind. Yep, that would be really cool. afro

But I also look forward to hear anything new ´bout Michaels Deluxe Quantizer!

I see. Well, when I first saw the Moon concept I thought all other developers of quantizers must have been blind. This is so clear and intuitive.

So the ATMega solution hadn´t worked out for you?

sneakthief · Joined: Jul 24, 2006 Posts: 569 Location: Berlin

I decided not to build it because of the jitter (deal killer for me), the max +5v input and the really fiddly calibration procedures.

glitched · Joined: Mar 25, 2006 Posts: 80 Location: phila., pa USA

In reality, if you feed it a good +5V power source, jitter is minimal and almost unnoticeable. I had a faulty regulator, which exacerbated the jitter problem.

There aren't any calibration procedures, as far as I know.

I can see your point on the >5V CV thing, but I haven't killed the PIC yet! Still, the extended range will be nice in the next version.

I know I don't need to be an apologist, but this was a great little project for me and I use my dual quantizer in nearly every patch.

Hi. Just wondering if anyone bought one or two more of these boards than they might need? Pm if so...

thanks

Hey guys, sorry about the delays on getting the next batch of simple quantizer boards ready.

After getting a couple prototypes of the new layout, I found a flaw in my layout and I'm currently waiting for some more prototype boards with a revised layout. I'm using Batchpcb.com for prototyping, and while their services are very affordable and easy to use; it's difficult to estimate delivery. So it might be another month or so before I'm ready to start selling boards again.

I been on break from working on the Deluxe Quantizer so I could work on a few other designs (Arpeggiator, VC Clock/Divider, Envelope Sequencer). I should be back to work on the Deluxe soon.

Thanks for the update. I bought 4 of the original PCB run to put on 4 sequencers that I'll build later...

...but then I decided to use one on a 2U high, 19" panel that will be built before the sequencers. The case it's going in is a 12U rack into which I'm putting 2, 5U high dual synth voice panels (2 VCO, 2 VCF, 2 Mixers, 2 Glide, 2 VCA, 1 VCADSR and 1 regular ADSR in each panel).

The 2U expander has a YuSynth Noise/S&H, one of your simple Quantizers, 2 CGS Utility LFOs (4 LFOs in all), and one VC Ring Mod by Fonik.

While designing the front panel, I realized that a quantizer in conjunction with the S&H and LFOs would really add a lot to this case. It'll give me some pseudo-sequencer capability before my sequencers are built.

So...when the new versions are available, I can get those for my sequencers and just use the remaining 3 PCB I have somewhere else!

More is more!

I am also very interested in a VC Clock/divider. Can you supply any more details? Features etc. and approximate availability would be appreciated.

Take care,
Doug

I've seen a number of quantizer designs that incorporate several channels on one module; sometimes 2, 4 or 8 channels of quantizer. I'm wondering if there isn't something about quantizer design that lends itself to having several channels. For me it would be very useful to be able to have several channels on one module or board, rather than trying to wire up a bunch of separate boards for power, ground, etc. for use in a multi-channel quantizer module-- which is what I'd like

Seeing as these boards are so small, I'm wondering if it might make sense to the designer or anyone else, if it was expanded into a multi-channel quantizer. I guess its also useful to have a small single channel board for incorporating in sequencer designs. But maybe a multi-channel would be practical also.
