bear in mind that it will be a bit more expensive for the second run as Jason is going to use a better pcb fabricator after the mess about with the keyboard part of the main pcb on run 1

Hello Jason, please put my name down for a kit of parts on the next run. Thanks, Andy

I noticed there was a problem with the pcb.
Even if it's a little more expensive, it's still a steal :sb:

Where can I buy a blank piece of black PCB to match the footprint of the synth? I want to make a base for it so the solder side is not showing.

At the moment it is not useable in my studio, as my keyboard stand is aluminium (conductive)

You probably cannot, as the black solder mask is applied after the PCB is etched so you won't find any that's already black. Just use a sheet of aluminium, paint it black and use suitable stand-offs to mount it beneath the main PCB.

I found that an A3 sheet of 3mm MDF from eBay woks quite well.

A MIDI problem I can´t understand...might intrest others. I use Elby Designs' Midi-Wasp-adapter. It works great on a cheap midikeyboard, which sends note on/off and midi note number, and nothing else, no velocity etc. But when I connect my Jasper to a Roland JV-80, JD-800 or Prophet-08, all I get is ONE note, then it goes silent. I tried to remove everything from Midi signal, but no help!

What on earth is this? It hampers my Jasper unusable in a Midi studio :(

Hi! I'm interested in a Jasper kit (panel,pcb,pots and CD4006). Thanks!

Jasper Round 2 is GO!

Post by jasonl » Thu Jul 14, 2016 11:14 am

Edit 18 July 2016

That was quick! Didn't expect this level of interest so quickly... :goo:

I'm still waiting on responses from people on the waiting list for the second run, so if included, then all the PCBs are now accounted for.

So I've started a list for a third PCB run. If I get any cancellations then I'll move people up. If you want to go on the list, it's best to PM me so I can keep track.

Cheers! :guinness:

Finally! Jasper 2nd PCB run is GO! :nana:

It’s been far too long, but the second Jasper PCB run is ready to ship. The new batch of boards look great – and the overall quality appears consistently better than the first. The silkscreen is a deeper yellow than the first lot, and the soldermask seems glossier.

Image

With the panel:
Image

Old (top) and new compared:
Image

There are some additions and changes on the PCB in light of some of the feedback from the first run:

* The enhanced oscillator waveform mods are now on the PCB – so no trying to find space for the daughter-boards. The middle of the PCB is more cramped to make space, but the result is worth it.
* There’s an optional external trigger input. This allows triggering/gating the envelopes with a positive voltage. It works well, for example, with the LFO and gate from the modular, and sync output of my Volca beats. Using a switched jack socket means it’s only engaged when something is plugged in.
* A better hold switch option – one that simulates holding down a key, allowing the repeat function of the VCA envelope to work. The one on the original run suppressed the decay cycle, preventing the repeat. The original hold is still available, allowing use of a miniature DPDT on-off-on switch for both behaviours.
* A couple of minor component changes have also been made to the BOM.

I am not offering full kits, but along with the CD4006 and switched pots as supplied before, I can supply a optional few extras that may be useful:

* Trimmers: 2x Song Huei 9mm tall trimmers from Thonk, and the four 6mm trimmers.
* Sockets: 3x Cliff FCR1295 3.5mm stereo jack sockets; 2x 8pin mini DIN sockets for the Link port; 1x 2.1mm DC power jack.

You will need to source the rest of the components, pots and rotary switches.

Pricing

The PCB costs were higher this run, but I hope the increased quality is worth the extra. And our politicians have done a good job of ensuring this is mitigated for those outside the UK.

* PCB: £26
* Panel: £18
* 3x Omeg Switched pots: £8
* 1 x CD4006 (or equivalent): £1
* Trimmers kit: £3
* Sockets kit: £4

So one of everything: £60
PCB, Panel, Omeg Pots, CD4006: £53

Postage/shipping is extra, and is determined by weight – up to 2Kg will go by Royal Mail.

A single set of PCB+panel, boxed and packaged weighs in at about 900g, so for example:
UK: 1st class Signed-for is £4.45
EU, Tracked and Signed Airmail is £12.50
USA Tracked and Signed is £17.20
Australia/Rest of World is £18.15.

Standard airmail is cheaper, but has no tracking available. So once it’s sent, there’s nothing to do if it goes missing en-route. Let me know if you want this, but it’ll be at your own risk. Packages heavier than 2kg (i.e. >2 sets) will need to go by courier, so I’ll use Parcel2Go on a case-by-case basis to get a reasonable price.

Ordering:
Send me a PM with your Paypal email address and your delivery details and what you want. I’ll sort out a Paypal invoice.

Over the next couple of days I’ll PM people on the interest/waiting list I made, if they already haven’t sent me their details.

If you expressed an interest earlier, but no longer wish to get the PCBs, let me know and I’ll free up the PCB for someone else. It's a larger run than before, but it's still limited.

Next step is to update the build guide, BOM, etc...

And here's one I made earlier:
Image
3d printed sides and standoffs, with lasercut acrylic base and back section for speaker, Elby MiniMIDI Wasp and eventually a CV/Gate interface. The design needs a bit of refining, but it seems to work OK.

Has the panel changed at all or just the main PCB?

Is anyone doing (or interested in doing) a full build for those of us who are less DIY-inclined?

Great work Jason!

The panel's the same design. I did move the Jasper logo up 5mm, and put some extra text on the rear, to show the locations of the headers for the osc volume pots, ext input pot, speaker and hold switch. This aids getting the wire lengths correct.

The other minor difference is that it is exactly 2mm thick (what I ordered) - the ones from the first run are 2.2mm.

The Knobs Group Buy will happen if we get enough interest. See the first post in the thread for more info.

New PCB and panel look great Jason, and a big :tu: for the tweaks and additions.

When I'm happy with the designs my plan is to post the STLs and DXFs for 3d printing and laser cutting respectively.
