DIN Rail Mount for Pi HATs - Raspberry Pi General

I've developed a new Raspberry Pi HAT mounting board for home automation use. It's plug & play, DIN rail mountable and can be daisy chained without any special adaptors or ribbon cables.
Here's an example using one of my development CTRL HAT boards with a Pi Zero. This is controlling a pair of 230V motorised blinds.

Based on my earlier DINPi board, one HAT RACK board supports 3 HATs or 6 pHATs with a Raspberry Pi mounted in 1 of 2 positions and fits into a standard 12 module DIN rail enclosure.
I mostly use I2C based HATs for home automation (I've developed some of my own too). I created a Python script to test multiple HATs based on the MCP23017 expander (as many are), which can be found here.
I'd love to get some feedback on the design. I have ideas for additional supporting hardware (including CTRL HAT) and would love suggestions.

Terminal Emulation Program & BT Serial Dongle

You can now use your Transformer to work as a terminal emulation program via Blue Tooth with a serial blue tooth dongle and the SENA Terminal APP available Android Market (Free). See below response From CS at SENA. I have not tried this as the Parani-SD1000 BT dongle goes for around $100.00.
Thank you for your interest in Sena product, Zigbee.
SENA BTERM is terminal emulation program for Android OS. From our knowledge, Android OS does not support ZigBee protocol. However, Android OS does support Bluetooth and you can use our Bluetooth Serial adapters Parani-SD1000 (http://www.sena.com/products/industrial_bluetooth/sd1000.php) to communicate with Android device through SENA BTERM.
If you have additional questions or need any assistance, please feel free to contact me any time.
Thanks.

Great, but it'd cost £75 to get one here in the UK, when a similar thing can be made with a PIC and a bluetooth module for under £10...
I just want a USB serial dongle to work

BT Keyboard Case MOD - OTG - USB HUB

Hello people!
I own a Samsung Galaxy S2 (I9100) and I've been fantasizing with a very particular MOD.
I've seen this Blutooth Sliding Keyboard cases:

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But I would like to get it working thorugh OTG, and take advantage of the extra height o add a USB port for USB DRIVES using an integrated USB hub.
This way I wouldnt need to carry around an OTG cable, and wouldnt have the constant drain beause of the BT pairing.
My main roadblock at this time is wether I could get the keyboard working through USB (bypass the bluetooth interface) so it could get recognized by the phone.
Once I can sort this out, the rest of the mod should be quite straightforward.
I dont own the keyboard case yet, so If anyone has some previous modding experience could shed some light on the bluetooth matter, it would be of tremendous help!
Thanks a lot in advance.
I don't have the first idea how to do this but I am very interested!
I like a physical keyboard and I've had to import from the US or stick with very outdated phones....

Lego QI Charger [Tutorial] #noSolder

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.

Joying Head Units Bluetooth workaround?

Sorry to bother you guys but figured I have tried two of the resident experts on this type of stuff with no luck, and I apologize that I am not very knowledgeable on this stuff. I totally redid my 84 Monte Carlo SS both outside and now finishing up the inside of it. While doing so I came up with the idea of having a dedicated head unit run a backup camera, air ride controls, and other accessory type of stuff. While having a second unit run the stereo and front facing DVR, I thought I was all set because it had Bluetooth and I avoided the issue of having my phone run bluetooth stereo on one while the other would be able to bluetooth for the air ride.
What I currently have is these two units, JY-UOS02N4PX5S and UK-JY-UOS01P4V. The UK-JY-UOS01P4V is the unit I was hoping to run the Ridetech air ride app on to control the air ride. But I can change how I have the two setup if it would make a difference, but think they are pretty much the same specs except that the UK-JY-UOS01P4V has fast boot which is part of the reason for choosing to run it on the accessory stuff. Thanks for your time and sorry for creating another thread but have searched through and not found anything related to my specific units. Here is a pic of the basic setup of them to mimic modern cars to a point.
