Anyone get one of these?

http://item.taobao.com/item.htm?spm=2013.1.0.0.OEDdax&id=38746408917&scm=1007.10039.737.0&pvid=ca181b91-0128-468d-9de5-58403815de91

Is that an aluminium case for 30$??

It looks like it :thumb:

But it seems to only be available in red and it is taobao after all so.....ymmv

Yeah that price is extremly low. Maybe painted instead of anodized? If it is anodized you could reanodize it, and if it's painted you can probably remove the paint somehow, I wouldn't complain about that for this price :))

Hopefully it's legit :-X

Received my GHpad pcb few weeks ago, I did a little mod and sanding since the plate layout is fixed and only clear acrylic case is available.

Surprised to see most people are making 6x4 pads, thought the majority would've made these for 60% boards. Dead keen to get mine built but I've been super lazy doing the CAD files for the case, kind of hoping that someone comes out with a CNC'ed case.
It's a good width!  If it's half-width it's too narrow, and full-width is too wide.

Has anyone that is part of this dev group tested this with the gh60?
Does this still integrate with the gh60 or is this it's own standalone keypad?

I am good either way I was just curious.

If the pcb's seem to be finished for these I would like to either source a pcb or split the cost of a batch @ oshpark with a few other people.

@IvanIvanovich -- It looks like the AboStudio Number Pad (which is a GH Pad) supports 4x5 layout.

Make sure the diodes are are connected the correct way.  I seem to remember there was a batch that was done with the diode silkscreen printed backwards.  Does anyone remember the details of that?  I remember others saying they had the same behavior and it had something to do with a mistake on the silkscreen and I think the fix was relatively easy (maybe time consuming though).

Anyone remember???  I am too lazy to find the post.    :blank:

Even if the diodes are on backwards, it should at least register on my PC no..? But no I have everything on correctly.

I missed much of the middle of this thread, but I now working on what is an extended-width version of the GHpad for use as a gamepad.

See thread here: input devices » Custom Programmable LH Gaming Pad

What I would like to do is add two columns to a fiver-row version of the GHpad.


samwisekoi gamepad v2.

 Electrically it should be simple to extend the rows -- but are there pad, pins, or traces where I could connect the two columns?  (Or the reverse if the PCB is row-wise instead of column-wise?)

Alternatively, if someone wants to point me to page nn of 32 in this or another thread, I am happy to look at circuit diagrams or schematics myself.

For general interest, the outcome of this request is likely to be some 1x5 or 1x6 extension PCBs that could be used by the inventive to extend the GHpad into other form factors as desired.

Thanks in advance, kind sers!

Every row and column on the GHpad is broken out to solder pads on the side of the PCB. If your expansion PCB had the column and rows broken out in the same manner, it should be trivial to wire them together and connect to a separate controller board, be it a Teensy or whatever.

Got it.  Thanks.

Is the reverse true?  Can I wire my expansion PCBs to the GHpad controller?  I can extend the rows by wiring to the GHpad row pads.  Are there places where I could ADD two additional columns?  Going from a 4x6 matrix to a 6x6 matrix?

I don't think any of the spare pins on the ATmega are broken out to pads on the PCB. :(

But don't quote me on that.

[Hits quote button...]

But there ARE spare pins on the ATmega?  Is there a good image of the PCB front and back somewhere?

Worst case I can always remap any of the new keys to unused keys in the existing 24 RC positions.

Thanks!

It looks like I can connect to Pin 20 and 21 here:


Closeup of GHpad v0.8 by regack

WITHOUT using the serial expander, of course.

Column 1-4 are on pins 13-16, so unless these are special pins, it appears to me like I could hook a couple of columns to those pins and mod the firmware accordingly.

Otherwise it looks like direct to SMD pins on the ATmega, which I would like to avoid.

Does anyone know if I could safely connect Columns 5 and 6 to Pins 20 and 21?

No, you can't, those two are to allow the GHPad to be connected to an I2C enabled device, like say the Ergodox, or some other future keyboard that has I2C enabled, so that a dedicated controller MPU is not required on the GHPad and an I/O expander can be used instead.

I haven't been able to be around much due to... life... but what you could do is repurpose the PB3 (MISO), PB2 (MOSI) & PB1 (SCK) pins from the pads where you could connect an ISP between S3 and S8, they're just as not conveniently located at the edge of the pcb.  I guess that would get you 3 extra rows or columns...



In that clipped picture, to the left of the MCPblahblah silkscreens is the GND pin with MISO below it.  The silkscreen for those is on the front of the PCB, and not the back.

i am not having luck programming my "red scarf" GHPad from the group buy

i made a hex file in the easykeymap app and used flip to flash, flip driver is installed and it shows it erasing and programming sucessfully and validates but when i unplug and plug the keypad back into the computer it does not see it as a keyboard. no input is registered on any key

anyone have a hex file i could try, maybe it has to do with the easykeymap app

I had the same problem using metalliqaz's easykeymap.  Ended up using regack's firmware (be sure to read the READMEs).  Not as nice or easy to use as easykeymap, but it works.  Note that I cut my PCB down to 4x5 (don't think this matters but pointing it out in case it does).

First I'd like to apologize if I shouldn't have necro'd a thread from over a year ago, but I wasn't sure if this post warranted a new topic. I've tried my best to follow this thread through in my course of building a GHpad.

I am still looking for a case for the thing since TaoBao was out of stock for the nice acrylic cases. I was curious if anyone had CAD models for either a 2-piece plate case (like the one JDCarpe made for TheChemist https://geekhack.org/index.php?topic=38963.msg1324791#msg1324791) or the multi-piece acrylic that MOZ made (https://geekhack.org/index.php?topic=38963.msg1167300#msg1167300); I'd also be interested in potentially buying one if available.

Recently I bought a GHpad board from TaoBao called "AMJ Pad". It looks like a modified version of regack's board with resistor positions for optional LEDs at every switch position as well as additional LED positions around the perimeter of the board. I wanted to get your knowledgeable opinions before I assume these to be true, and I also had a few questions.
The boards can be seen here:
109491-0109493-1

Below I've labeled a few positions on the board I had a question about:
109495-2109497-3
  • On the bottom side of the board there's a switch labeled "REST" (on the reverse). This seems to be the same switch seen at the top center of the regack design - what is this switch for?
  • There's a SMD solder point below the switch called "LED", anyone know what the LED might be for?
  • There's two sets of Through-hole solder points labeled R1-R5 and C1-C4 in the highlighted markings "Unknown Pins #2 and #3". I'm assuming these are the row and column break outs mentioned by JDCarpe a few posts up.
  • On the top side there's a set of 6 through hole solder points for "MOSI SCK" in the box "Unknown Pins #1". Not sure what those are for either

Just to recap what I am currently assuming:
There's 24 switch positions on this board since it's basically the 6x4 layout by regack complete with the sort of breakaway bottom row. Each key position has a diode SMD solder point designated by D1-D24. Diodes are required for key operation. I'm doing a 21-key config so I only need to solder diodes for the relevant switches. I will probably solder all 24 on, since I have no idea which diode corresponds to which switch position.

Additionally each switch position has a resistor solder point for optional LEDs on switches in positions RL1-24. If I don't have an LED on a switch, the resistor is optional. Resistor sizing depends on the LED voltage needed.

There are 15 LED positions on the perimeter of the board. Each position has 4 solder pads, 2 for the resistor, 2 for the LED. I have no idea if the resistor goes first or the LED. I have no idea what orientation the polarity is for those solder points for the LEDs. The solder mask is slightly more bulbous on one side, maybe this means something.

Everything above is stated as my interpretation, not fact; please correct me if I'm wrong!
Thank you very much for reading.
