That solder mask has a bit of a half face/phantom of the opera thing going on. It kind of would have fit the Phantom. Are the markings for the diodes on that side visible at all? I guess one just has to double-check the orientations of the SMDs more carefully.

Yeah, it's very unique/odd. You can see enough of the diode silkscreens to guess how the others are oriented. We will need a guide for where to place other components, though. :)

Wow, that's crazy, I have no idea what might have happened there.  Yeah, no way to place the components without a guide.  It looks like a nice curve though... Maybe you can find the center point, seems like it might be off the board... I was just thinking perhaps a decimal point got misplaced for some silkscreen item?  I didn't see that in any test render or anything.

woah, is the pcb half black on the back? so weird  :D

I didn't generate my own gerber files, just passed them the ones regack generated.

I am also out of town, we can coordinate shipping when you're back  ;D

They are the same as the 6-row version, so...

I'd say not

well, the markings are correct to electrically indicate anode/cathode... but not necessarily with respect to how the diodes themselves are marked by the manufacturer... I ordered some SMD LEDs... two different brands... they had the EXACT same markings on the bottom... but were opposite from each other... it was really annoying.

Just want to point out to WhiskyTango and anyone else who got diodes from WhiskyTango. The sheets he sent me did in fact show that the band was to signify the cathode (-) end and not the anode (+) end.

Yep, that's what I was going off of when I placed mine backwards the first time... at any rate, there seems to be some non-uniformity as to how some smt diodes are marked. I think next time I am going to solder in just one and test it before I go farther, just to be sure.

And those PCBs look pretty cool I think. The lack of markings just adds to the challenge ;)
I stay busy with work and family these days, but I'm still around, lurking.

so I seem to be getting the same problem that defying had. I plugged in my GHpad and windows doesn't seem to be detecting it. It shows up as an unknown USB device. I tried running FLIP and DFU and both weren't able to detect my GHpad.

Edit: I don't know how and I don't know why.. but I'm missing C7. Is it possible that's why it's not working? If so, does anyone have a spare C7? Or is there a link to where I could get one?

If it hasn't been programmed yet, you need to updated the driver on the unrecognized device with the DFU driver from the Flip installation directory.  I've said it so many times...

And sometimes I haven't even got that to work. I had to program my GH60 with dfu-programmer on linux. Couldn't get Windows to recognize it at all, even after uninstalling/reinstalling the Flip driver.

Honestly I wouldn't be posting here if I hadn't already tried that. I've tried FLIP as well as DFU-Programmer.

I guess I'll have have to try it on linux after then.

Ok.  I'm not sure if it will or won't work with that missing... or maybe not work right?  Could be why it's acting up.

I hope that's the problem. Worse case scenario is something blew up because the capacitor wasn't in. Hopefully not since it was one of the capacitors for the crystal.

Those are C1 & C2 - C7 just happens to be nearby

Ok, so I finally saw what everyone has already seen and I failed to see D: - anyway, I fixed the silkscreen on the SOD-123 diodes to indicate the line properly.  The anode/cathode indicator in the middle stayed the same, just the line moved to the other side where it should be.  Sorry about that.

fixed for both the 4x6 github files and 4x5 github files.


There's also an error with diode D5 (switch 5, the '0' key).  It works fine, you just have to install the diode backwards from all of the others.  I didn't quite catch this, since installed some of the diodes backwards at the bottom of the board  :'( ... only working on the 4x5 version did I catch it.  The silkscreen and whatnot is fixed in the posted github revisions.

So... anyone got an ATmega32U4? Everywhere I'm looking that ships to Canada is out of stock.

While I'm at it if anyone has:

Molex 67503-1020 mini usb
ADTSMW69NVTR Tactile Switch (what is this even for?)
7M-16.000MAAJ-T crystal oscillator

I need those as well. I think I can order these but if anyone here has extras I thought I'd ask around first.

It's packed in a different tray/reel, not suitable for pick and place manufacturing at a PCB fab.

For our purposes, it's exactly the same.

Got my capacitors in from WhiskyTango and soldered them in. IT WORKS! Although I don't know how to get the LEDs working, do I need to actually put it in the firmware to get them to work? And if so, how do I do so with metalliqaz's easy firmware?

I'd really like to thank everyone who's helped me out with making the GHpad. It is technically the first group buy I've been in and it's been a really positive experience. Thanks to, TFR/Regack/MOZ and everyone else involved in design/distribution as well as Halverson and Kravlin for selling/giving me that awesome miami stuff, WhiskyTango for passing along some parts that I needed, LONGZILLA for being a sick secret santa and everyone who helped answer questions that I had and helped troubleshoot.

Yeah, there was a darker purple that I didn't see until after I ordered this one, but it still turned out well.

P.S. So, how would I go about getting the LEDs to work? Also, how can I change the firmware on it? I tried using FLIP but it isn't connecting to the USB. Do I have to press the reset button?

I'm guessing you still haven't got yours? For what it's worth, I never got around to building mine, even though I got the first beta going along with TFR. Mine was sent to my SS, who hasn't logged in since 19th Dec.

Where'd you get that cable... I wants one...

Try hitting reset to change the ATMEGA into bootloader mode, I don't think it defaults there.

From FLIP you'll then make sure to change to the atmega32u4, then select USB.  You might have to update the drivers to get it to see everything.

not right now, but I will be after I get my phantom operational again. Both of my TKLs are down right now.

So ray, did you just never get your PCB? that sucks

JD will get to it eventually, I hope, he's a busy guy.

Looks great, specially with that purple cable.
Yeah, there was a darker purple that I didn't see until after I ordered this one, but it still turned out well.

P.S. So, how would I go about getting the LEDs to work? Also, how can I change the firmware on it? I tried using FLIP but it isn't connecting to the USB. Do I have to press the reset button?

Where'd you get that cable... I wants one...

Try hitting reset to change the ATMEGA into bootloader mode, I don't think it defaults there.

From FLIP you'll then make sure to change to the atmega32u4, then select USB.  You might have to update the drivers to get it to see everything.
I got the cable made by TFR. It's nice right? :D

Hey everyone. I'm getting some extra cash for my birthday and would love to try this out as a little hobby and intro to soldering (as well as acting as an extension to my TKL in case I need a numpad for some reason).

As far as I know there are not any group buys going on, so I will have to purchase the PCB myself or find someone who is willing to sell one. Is there anyone I should get in contact with besides phatdood9 (who just ordered a batch)?

I would also like to confirm that this http://geekhack.org/index.php?topic=38963.msg1157872#msg1157872 is the correct parts list to order from mouser/digikey (in addition to the switches and keycaps).

Thanks in advance for all the help :)

found some pcbs in the mail today, thanks JD

looks like the manufacturer had a hiccup on the back, but it should function okay

for the 4x5, this is the most recent:


will be a couple weeks before I have the chance to solder everything up

Well I'm not 100% sure whether those resistors in the last photo are the correct direction. I have them in on a board using the opposite convention with the stripe and its working out.

Anyone using hasu's firmware? The bottom row seems to have some issues, but strangely enough if I load a 4x6 layout into the 4x5, the bottom row works (equivalent to the 2nd to bottom row on the 4x6)

Resistors have no polarity, so it shouldn't matter unless you meant diodes.

And, I too think, regack has got the polarity/convention slightly wrong, the bar is _ALWAYS_ on the cathode end, in the image above, the bar is on the anode end, which I would say is wrong.

so tired, yes I meant the diodes

I think its a firmware issue

regack posted about this earlier and said he fixed the problem, but I think those PCBs phatdood has were made before regack fixed it. See below

Ok, so I finally saw what everyone has already seen and I failed to see D: - anyway, I fixed the silkscreen on the SOD-123 diodes to indicate the line properly.  The anode/cathode indicator in the middle stayed the same, just the line moved to the other side where it should be.  Sorry about that.

fixed for both the 4x6 github files and 4x5 github files.


There's also an error with diode D5 (switch 5, the '0' key).  It works fine, you just have to install the diode backwards from all of the others.  I didn't quite catch this, since installed some of the diodes backwards at the bottom of the board  :'( ... only working on the 4x5 version did I catch it.  The silkscreen and whatnot is fixed in the posted github revisions.
