but if you can't even reach it with your tip, you don't have much chance
That's what I was thinking.. A hot air gun would be very handy for this. Maybe i'll see if I can find a better tip for the job.
try the hot air gun first - it`s easier than you think.

You would need some reflow solder which is hard to use in a space like that.

Received the case in the mail today! I feel there are a few small things that need to be changed but overall it looks great.

As we know for different people they use different kinds of mobile phone signals. Just as the people around you like your friends, your colleagues, your family members and so on, they may use the different mobile phone signals as now there are various mobile phone signals from different companies and of which the frequency bands are also different such as the CDMA, GSM, DCS, PCS, 3G, 4G LTE and 4G Wimax. So in different conditions and circumstances people are in need of the cell phone signal jammers that of different frequency bands. But if people are in great need of a cell phone signal jammer via which they can decide the jamming frequency bands what kind of device should they choose? Of course, the adjustable cell phone jammer is the best for them in such condition.

GG. I give up. I lost 2 diodes, broke 1 and now I don't have enough diodes to finish. I got 1 diode and the crystal on. I don't know how the hell you guys got those fricken diodes on but I sure couldn't.

The alpha prototype would fit SOD-523 diodes best probably (http://www.mouser.com/ProductDetail/Micro-Commercial-Components-MCC/1N4148X-TP/?qs=sGAEpiMZZMtoHjESLttvknyDsOtDHAfwI2C3xiL1dBQ%3d) but I just ordered 1000 of the SOD123 ones, so I can just send you some of those if you want.

$20 shipping charge for 25 diodes. I do not even understand. I believe whiskytango ordered some of the 523 diodes so I went ahead and sent him a pm.. I just hope I can actually get this thing built without any problems.. I honestly can't figure out how you guys managed to solder on the SOD123 ones.

It's a good width!  If it's half-width it's too narrow, and full-width is too wide.

I got the 523 diodes in today. I haven't soldered yet, but I did a test fit. They seem to fit perfectly, but holy crap are these things tiny. It is incredibly difficult to see the cathode band even under magnification. I think all of my extras are already spoken for, waiting for final responses from two people.



The alpha prototype would fit SOD-523 diodes best probably (http://www.mouser.com/ProductDetail/Micro-Commercial-Components-MCC/1N4148X-TP/?qs=sGAEpiMZZMtoHjESLttvknyDsOtDHAfwI2C3xiL1dBQ%3d) but I just ordered 1000 of the SOD123 ones, so I can just send you some of those if you want.

Aw man, I didn't see those when I was ordering. The ones I got were slightly more expensive, but the specs seem to be similar enough that they should work.

Actually just bought some off of whiskytango. The timinggggg. But thank you for the thought jdcarpe :)

Just sad that I have to wait even longer to get my ghpad made, but I know for sure I can't get it done with those silly 123 diodes.

Well, I only ordered 100 of them, not 1000. :)

But yeah, I tried the "mounting at an angle" technique, but gave up after like 4 diodes and ordered the 523 size from Mouser.

It's no big deal MOZ. Like you said, it's a prototype. And this is why you do prototypes, to find bugs like this. I view it as an opportunity to learn. I didn't know about the different package sizes for diodes before this, and now I do.

Can we start making a list of things that need fixed for the final groupbuy? First off there is the diode sizing issue. Any other problems anyone has encountered when building a prototype?

This is coming along great!

I'm visiting a friend who runs an electronics factory over in asia for the holidays, gonna see if I can have him make me a few pcbs with everything soldered on. They probably have everything on hand other than the ATmega32u4.

Looking forward to hearing about revC!

Have no clue what revision it is, I haven't been keeping up at all with this thread I'm just going to build it and let you guys know what difficulties I come across. What diodes do I need? Anything else I need to know or can I just assemble and program as I normally would ?

From the pads, it looks like you need SOD-123 package 1N4148 diodes.

Yes, SOD-123.

In theory there are three different ways to run this thing...
1) atmega32u4 on board (with ancillary bits)
2) mcp23018 slaved to something else (i2c pads on left side of the board)
3) directly wiring the rows/columns (from the pads on the left side of the board) to something else

At some point I guess I should test slicing off the bottom for 4x5 instead of 4x6.

Parts list is the same as the previous one, but I'll get a list together just to make sure. 

I just got 1000 SOD123 diodes, so I can help with that.

Well, I hope they tested them first...  (I can't see the link, it's not loading for me.)  I know there were tiny problems with previous revisions, and this one is pretty significantly different than the one that people are currently testing.

There will be more... unless everyone votes for yellow or something

So this is previous rev:

This is the experimental?

You're going to make your own prototypes? Okay. :P

I bought my 32U4's from DigiKey thru metalliqaz, but I think they went out of stock...not sure.

And some resistors and capacitors, I'm guessing. :D

Gonna get 1 of each made if so  ;D
Where are you guys getting your atmega32u4s from?

You're going to make your own prototypes? Okay. :P

I bought my 32U4's from DigiKey thru metalliqaz, but I think they went out of stock...not sure.

Gonna get a friend who owns a manufacturing business in asia to make a couple for me, need to pick up some atmega32u4s as they  may be difficult to get off the shelf and I want them to do the smd soldering

They're out of stock at Digikey, Mouser, and Newark.  I saw it coming and tried to buy a bunch of them, but screwed it up.  Still kicking myself over that.

Wow, I thought mouser had some left after that... they're all out now?

mouser seems sold out http://www.mouser.com/ProductDetail/Atmel/ATMEGA32U4-AU/?qs=SSucg2PyLi7mKWjHIsNJ3w==

Mhmm, I was asking for what I needed :P

1    1   ATMEGA32U4-AU-ND    IC1
2    2   1276-1047-1-ND    C1, C2
3    1   1276-1066-1-ND    C3
4    5   1276-1003-1-ND    C4, C5, C6, C7, C8
5    2   RMCF0805JT22R0CT-ND    R1, R2
6    2   RMCF0805JT10K0CT-ND    R3, R5
7    1   887-1125-1-ND    X1
8    1   679-2461-1-ND    S0
9    24   1N4148W-FDICT-ND    D1-D24
10    1   ED2992CT-ND    J1

Something like this, I think...

you're talking plain atmega chips, right?
froogle told me about Karl's.
Or you can actually get the thing on a breakout board for cheaper from a few eBay shops ... namely, the leonardo microcontroller ... not sure how safe it is to try and desolder one of those things but for about $5 you can try, and see!

(hmm. Looking for a good eBay link I found Fenwall but they want $12 shipping on a $3 item.)

If you wanted to attempt to desolder a 32U4 (hopefully in TQFP44 package size) from a breakout board, you might want to use Chip Quick. Otherwise I foresee a hard time.

Or get an SMD Quad tip...

Don't even bother trying to desolder them.  It's not worth it, trust me
