Does anybody know what measures this has?

I need to know positions of supports that go through the PCB or plate and the outer-dimensions of them.

Also: Is there enough space to place a Teensy 2.0 in the top row?

The plan is to make a replacement PCB/plate to get better space bar support (4, 6.25 or 7 units).

How is the bottom row layout gong to be?

At least it should support these bottom rows:

Code: Select all

  1   +1.5 +1  +1.5+1.5+1 +1.5 +1   +1    +1   +1 + 1+1+1  # maximum
  1   +1   +1          +7           +1    +1   +1 + 1+1+1  # 700  (3 mods each side)     
  1.5 +1.5             +7           +1.5  +1.5    + 1+1+1  # 700 (1800-style)
  1   +1.5 +1  +1.5+1.5+1 +1.5 +1.5 +1    +1.5    + 1+1+1  # 7BIT (like Tipro should have done it from the beginning)
  1   +1.5 +1  +1.5    +4      +1   +1    +1   +1 + 1+1+1  # 400 (Tipro-style)
  1   +1.5 +1  +1.5    +4      +1.5 +1    +1.5    + 1+1+1  # 400  (Tipro-style, with 1.5 units mods at the right)
  1.25+1.25+1.25          +6.25     +1    +1   +1 + 1+1+1  # 625 (for you Windows people)
  1.25+1.25+1.25          +6.25    +1.25+1.25+1.25+1.25+1  # 625 no cursors (for you Windows people who don't need cursor keys anymore)


BUT:
I still need the measures, otherwise this will not fit into an existing Noppoo case!!!

I have a poo here, what do you want measured?

The PCB and plate should fit into the Noppoo case. Are there any holes in the PCB or plate?

A photograph of a disassembled keyboard from above and the PCB from below would be nice.

No screws at all in the keyboard, unless I've missed something. The case snaps together and the plate with PCB is just lying there. I have the 2012 version (revised nav column, old modifier sizes, fixed cable). There isn't much space, but the case is slightly angled, which leaves a gap around the cable.

I also own a noppoo choc mini, first version I think. I can also make some measurements if needed.

Yes, please!

The PCB is 31×11.8 cm. Plate is basically the same from the top, but it's bent in the front and back to cover the gap between it and the PCB, as you can see here


(a,b,c,d,e,f,g,h)=(4,3,3.5,10,7.5,5,24,34) mm

echo "a,b,c,d,e,f,g,h=4,3,3.5,10,7.5,5,24,34" | sed 's/=/\n/' | gtab -t',' --transpose | sed 's/,/=/'
a=4
b=3
c=3.5
d=10
e=7.5
f=5
g=24
h=34

Looks good!

I need one more measure:

k=12 mm

a=4
b=3
c=3.5
d=10
e=7.5
f=5
g=24
h=34
k=12
a+c+k
19.5
Teensy requires about 19mm width.
keyboard is 118mm deep, ie
(118-19.05*6)/2 = 1.85mm on each end extra space.
19.5-1.85 == 17.65

Can't you ask questions in a way that's easier to notice? I've updated the page only by accident and wouldn't have known about the latest picture at all.

It's a little over 1 mm and yes, the line looks about right.

Sorry!


But might work out to place the Teensy under the top row.


I'll order a prototype soon, then we will see ...

I finally got around to do the measurements (all in mm)
a = 3.5
b = 3
c = 3.5
d = 10
e = 8.5
f = 5.5
g = 23
h = 33.5
k = 12.5

topmost support is about 1mm thick and 2.5mm high. I'd say the topmost support runs a little bit higher than your yellow line, but not by much.

Thanks!

Code: Select all

a|  4| 3.5|gap to top of hole from upper PCB boundary
b|  3|   3|gap to left of hole from right PCB boundary
c|3.5| 3.5|diameter of hole
d| 10|  10|height of topmost support
e|7.5| 8.5|height of support below
f|  5| 5.5|height of support below
g| 24|  23|gap from case-edge to topmost support
h| 34|33.5|gap from topmost support to support below
k| 12|12.5|gap from topmost support to lower boundary of hole
W|310| 311|width of PCB (12.25"-0.75"*16u=.25";  12.25"*25.4=311.15mm) ??
H|118| 117|height of PCB


BTW: Further up would mean it touches the solderpads! Are you really sure? I placed the line such that it is between all solderpads, so does not run over one. It seems the only possiblitiy.If this is where the support touches the PCB, it is within the boundaries of the 2nd row from top, so would not get into the way of the Teensy!

Nope, not sure at all, I checked again, and where you placed it is correct.

Height was for the bottommost support, but thickness is the same for all.

Could you please measure the overall dimensions of the PCB?

davkol gave me 310x118mm, but I don't trust him.

Ah right, I measured it but forgot to give the numbers I got 311x117 but I don't trust the 311 all that much (my good ruler is only 30 cm so I had to use a different one).

Ha, you don't trust my Vernier scale Made in Germany? ^w^

Also, the corners of the plate are a bit 'cut off' as the plate sides are folded beneath it as davcol explained

What is the highest precision you can measure with it?

I think 0.2 mm (yes, the results above are rounded).

…and hey, I'm davkol, thank you very much.

Do you still have the unrounded ones?

310×117.2 mm PCB

(a,…,h,k)=(3.5,3,3.5,9.4,7.6.5,24,33.8,12.4) mm

(a,b) vary depending on side (+/- 0.2 mm), case measurements are all over the place (+/- 0.4 mm) and especially k is very tricky to measure, because the tip in there is much smaller than the hole in the PCB.

I've become disillusioned about my choc mini in the last few days. Sure it has genuine Cherry MX switches, decent plate, great keycaps and some nice features, but solder joints look awful (all of them except the few LEDs and SMD parts) and the case is uneven and very flimsy around the cable connection.
