Lego QI Charger [Tutorial] #noSolder - Hardware Hacking General

Hello, this tutorial is for people who want a wireless charger that is cheap, easy to assemble, and easy to modify/decorate (and works with cases). Inspired by this thread http://forum.xda-developers.com/showthread.php?t=2545350 (too tricky for me)
You will need the following:
Lego (see pictures)
QI coil
1) Make the base. The bottom slab is 8x8, has to be thin as coil is placed ontop! (Note my base is gridded and I have little coil decorations, this is purely aethetic)

2) Add coil
3) Add the bottom cover using a 6x6 panel and two 8x2 (Don't press down too hard or you might damage the circuit board
4) Optional fill in gap between planks
5) Flip over and you're finished!
​All this for US $15.58 + some lego!

That is pretty awesome, and thank you for post where you got the Qi coil from

Pretty fantastic.

Crumpler Case The p.p. 55

Hi,
I'd like to share with you that I am using a Crumpler case for my HTC TyTN II. The case I am using is called The p.p. 55. It fits the phone perfectly and is great for taking in and out of pockets. The only disadvantage is that it zips all the way round so is not particularly wired headphones friendly as you have to leave it unzipped at the bottom but overall I am very happy with it as a phone case.
Cheers,
andrew-in-woking
Got a link ?
I dont want my loose in my pocket, but the standard case that came in the box is way too bulky for when wearing jeans.
the att tilt (us version) doesn't come with a case. andrew, do u mind taking pics and posting them? i used to have the seido case which is awesome! i have the invsishield but haven't installed it yet.
With a quick google search I found it on amazon here.
Doesn't look too bad, with a variety of colours.
This was the original one that came with the phone:

The massive problem was the un-removable clip on the back. I say un-removable, but it can be removed, though it would have to be permanently by clipping it off.

Charging pins

Does anyone know what the two pins under the cover are for? They look like charging pins which means that wireless charging might be possible with a different back plate or a modification? The review on Forbes today suggests that.

They are only used in the China market running H2OS.
When plugged in the H2OS will adjust the theme of the phone to match the new cover style.

Reviving old thread for new random question.
We now know the 2 pins under the cover are for the H2O styleswap themes, but looking at a teardown of the OP2, is it possible that it could "tapped" into for wireless charging and/or NFC?

[Q] Can you identify this part?

Opened up an old PC on a stick to see what I could do to improve wireless signal and ended up breaking off what appears to be a part of the wifi antenna however I have no idea what it is correctly called, a few google searches and I come up short. I want to know what the part is called so that hopefully I can find out how to reattach it.
The part looks like a gold color pin that pushes in, sort of like a micro plunger. When the case is put back together there is a metal plate on the case that makes contact with this pin to create an antenna of sorts.
I would just solder it back on but I can't make out any metal contact left to solder to on the spot where it broke off from.

Howdy mate,
That's a surface mount pogo pin, Lson is a company that makes them, you could probably salvage one if you could find an old car kit or phone charger from the late 90's. You could also replace it with a piece of springy steel from a battery terminal but that might affect the antenna wavelength.

Thank you!
That is exactly correct

Solder should look like 2nd one counting from right, about 1/2 shorter and bit flatter.
source: learn.adafruit.com
Now it is time to reseat pins height since they will need to stick to new solder point. I marked for you those pins and all you need to do is raise them a little bit, not too much or they will break apart, just do it gently.

THE END
If you did it properly your GPS fix should be much faster and more accurate than ever.

Maze Alpha won't charge with new lead (SOLVED)

Hi guys, so after reading another thread on here I managed to get my phone charging. Like others I managed to catch the lead while charging and it damaged the USB-C plug on the lead, just enough so that (at first) it simply wouldn't charge. I managed to get charge by forcing the lead in a touch and having in the "right place" and of course, not touching the phone while it charges. I also wanted another lead so I could charge in the car.... but of course, it also doesn't work if the USB-C lead is plugged in upside down (sic)
I purchased replacement leads thinking the first was broke, the next didn't work either.
This is as some have pointed out because the USB-C socket on the Maze Alpha is sunk in further by about 1 mm. So no standard made lead works.
SO I took one of the other leads and trimmed off about 1mm of the rubber/plastic (See red line on image)

and it works perfectly. So I trimmed my existing official Maze Alpha lead and that also works perfectly now too.
Of course, if you wish to do this, don't buy one that has a metal shroud or surround on the base of the plug. Please also be careful not to cut yourself.
