International Customers for Q-tune kit

For any international customers, I've been thinking about a No Screen / No Enclosure option.
  • Purchase the screen here: Waveshare with touch.
  • Purchase the enclosure from Tayda.
    • Drill/UV templates provided.
  • We'd subtract our cost of the screen and enclosure. Sell for $112 + shipping.
Without these two items, it should allow us to ship UPS International for a reasonable rate, it will likely vary by country. Shipping would probably have to be on a case by case basis.

If this option is of interest, let us know.

Thanks!
 
Thanks for looking into this.

If anyone is wondering, the screen can be found for 25€ in the EU and (reliably?) 20 something on Aliexpress. And with the lower shipping and kit price, that would put the total under 150€+screen+enclosure so a fair bit cheaper than a full kit direct - especially because 150€ is a classical threshold to start paying import duties on top of VAT.
 
€150 also being a threshold of "just buy a commercial tuner" — unless you steadfastly wish to build your own tuner.


With shipping, duty/customs fees and tax, mine is definitely going to be quite a bit more expensive than my Turbo Tuner.

However, my Turbo has side-jacks (I was about to rehouse it with top-jacks when the Q-Tune was announced!), and my Turbo doesn't have fun & games/screensavers, my Turbo doesn't have a screen that can be oriented the way I want regardless of the pedal's orientation, my Turbo doesn't have a touch-screen that easily lets me adjust its parameters... the list goes on.

Lastly — My Turbo wasn't built by me.


Glad to see the Q-Tune guys pushing for ways to make this DIY-Tuner available globally.
 
We have plenty of screens now, and a couple 1590b’s left in the first batch. We think we can ship most places internationally for $35 UPS.

I'm wondering if there is any advantage of doing No Screen or No Enclosure. What would be the preferred option?
a) Full kit - $149 + $35 shipping
b) No enclosure - $137 + $35 shipping
c) No screen - $124 + $35 shipping
d) No screen, No enclosure - $112 + $35 shipping

The screen is by far the most expensive part of the kit, roughly 1/2 the total cost. So by having international customers buy it themselves, wouldn't that mean lower duty/customs? Without the screen, we could list the customs value at like $50 or something low like that.

I don't know much about this. Please advise. We are happy to provide the best option that is the most economical.

Here in the UK, a competitor price of a Peterson is £120 (mini), £130ish (larger HD). Given we pay tax on shipping costs, that means 20% VAT covers both shipping and component price, it's going to put quite a pressure on the total DIY kit cost.

$149+$39 = $188.00 which is £139, then add 20% comes to basically £167 to the end customer. US goods under £136 (that's not including transport IIRC) means 0% import charges.. Over that and it could be up to 12% extra on that. Typically the US sender will not see that cost, but the receiving party will get a nice bill before they can pick up the parcel.

One way to perhaps differentiate (and be more attractive) is to add a luthier mode that provides some additional features with 0.01 Hz (with 96Ksps that should be accurate with 10x oversampling) to 2.4KHz.

A really cool feature would be:

Be able to set up a scale length, with a temperament, number of strings and frets, the nut and string spacings, It's easy then to create a fret frequency (including the slight differences between the strings due to string offset from the centre line).
Calibrating then setting a dB reference Vpp.

Rather than expend processing time attempting to detect the fret being played, or attempt to analyse the fretboard in it's whole, you could simply do the following:

[Hz detected] [note][octave] [dB]
[string 1 fret position] [cent] [dB] [heat map of readings vs centre frequency]
[string 2 fret position] [cent] [dB] [heatmap .. ]
..
[string 7 ...] [ cent] [heatmap ..]

If there's not a match simply make that string's space blank.

This would allow the guitar builder to see the accuracy of the frets.


I was building a python tool to take a sound clip of barred frets (from open to 24) to then build up this picture, ..I've got part way but time I don't have to really continue with that, so I looked at hacking the open daisy GitHub code and doing something similar.

The phase correlation approach is one I'm familiar with - I've done this with 2D and 3D image alignment using FFTs of the axis pixels strips. Also phase correlation works well against noise. I assume you're then displaying the phase peak vs reference peak to give the movement.

That’d be an interesting project to tackle and one that is probably better suited for a full on desktop computer app would be my guess. Let’s say a tool like this maps out your fretboard … is it just informational or would you then take that info and modify the frets by re-crowning them/etc?
