input voltage - Nvidia Shield TV & Shield TV Pro (2019) Questions

I know the “ flat “ 2019 sheild is capable of input volt of 110 and 240.( 220 )
My question is , does the USA/CDN Tube 2019 have the same capabilities.
So if i have one is North America, can i use it in UK??
Anyone know for certain?

External temp Probe with Android Galaxy Note 2

http://www.amazon.com/Powered-Therm...0054U4YKI/ref=pd_sim_pc_1/191-4837767-5075164
Hi all, I need a thermometer for measuring the temperature of hot pie displays and cupboards etc. I use a Samsung galaxy Note 2 phone and I have bought the TEMPer1 usb temperature probe. My problem is I can't find any software with which I can use it on the phone.
The phone has OTG (on the go ) capability and can use wireless mice and USB thumb drives etc.
I have read the posts relating to Linux and Java etc but not sure how to compile a program script etc.
Can anyone help with a solution ? I am surprised that these temperature units are not catered for on phones as portable temp readings must be useful for a lot of people. Especially when the probe is remote from the phone.

What ethernet speed depends on? (100m - 1000m)

Hi
I've bought a 'x96 x4 1000m' device recently which turned out to be a 100m one at last. I've opened a dispute for partial refund which I won, but I'm still not satisfied, need answers.
In short: What differences on the PCB shall I look for in general, if a device officially offers 100m and 1000m model variants?
Actually I did some investigation on this particular model and found this:
A test on an 1000m device. (The review is a possible proof that 1000m devices of this model do exist. I don't speak russian though and automatic translation is trash. If I put correctly together the review, the box is trash too, but that is a different story.)
A review on a 100m device.
Now the twist. (To me) both boards look identical! Both are equipped with this component. Unfortunately I'm not an electical engineer, so it is not a fact but only suspicious.
May 100m be a software limitation only? Would be justifiable from manufacturing point of view, but simply stupid from marketing perspective.
So I've learned today that an ethernet controller chip should be present on the PCB to provide gigabit ethernet. That piece of chip is missing, so having a 100m lan is not coincidence but actual hardware bottleneck.
i bought x96 x4 64GB ROM/LAN 1000, and when i tested the LAN it only has 100mbps, but i found out that it is not compatible with the network plug, that plug i plugged into wifi6 it broadcast with 5Ghz ac is 250mbps, my network broadcast is 400mbps if test with LAN 1000, if I want it to receive LAN 1000 then I have to replace the network end again, I take 1 gigabit LAN port on wifi 6 and plug it back into x96 x4's LAN port it gets 1000mbps. If you want to know if your box is LAN 1000 or not, you have to test plug the box into PC, 64/1000 with the codename in the introduction if it's X96_X4_Pro, then it's LAN 1000, and if its showcase name is X96_X4_Pro1 then is LAN 100
I've already sold the box to someone who didn't mind having 100m only. And yes, if I remember correctly it had a name X96_X4_Pro1.
Actually I've been testing it with a 10Gbps cable hanging from a gigabit port of a wifi6 router. The very same cable provides to this day gigabit connection to an older box of mine with actual gigabit port.
So yeah, everything is just correlating nicely. The naming convention of this particular box, the connection speed with a well performing cable, and of course the missing piece of hardware (gigabit controller chip).

Building a Raspberry Pi based A/C controller

We just got into a new house and the heating and cooling are done using an Atlantic R32 duct type unit. Since it is blowing in all the rooms at the same time and the fact that the wired controller with the sensor is right underneath one of the vent, we have a lot of trouble getting the whole house to a satisfying temperature.
It would be a lot of money to get a brand new system with a better room temperature control, so I was thinking I could maybe use a Raspberry Pi or Arduino instead of the wired controller to create a web interface that I could use from my phone and connect multiple sensors in order to have the temperature in each room.
With the documentation that is provided for technicians, we can see that that the wiring is made of three cables, a 12V, a COM and a signal cable. I would have expected a RX and TX cable along the 12V and COM... So I'm a bit at a loss at how to start here. It seems like the communication goes both ways since they mention a discovery phase for the remote control.
I would like to know if someone has experience with hacking this kind of device and what I could do to retrieve data frames or even discover the sampling rate ?

Hacking & Reverse Engineering of Tata Sky HD STB ( Technicolor : DSI729TAT )

I have a "Tata Sky HD" Set-top Box and I was about to throw this in garbage but before I want to know what is happening under the hood.
I search on internet and I found nothing except this. I'm noob so sorry for if say something silly.
I found this specifications.
Product : TATA SKY HD
Original Maker : Technicolor
Product Model Number : DSI729TAT
Chipset : STiH237 BHKB B3L
Type : ST40 -32 BIT
Architecture : RISC
RAM : 2GB [ SK Hynix H5TQ2G63FFR H9C
Storage : 1GB [ Spanison ML01G100
Power : 12v DC
Software: busybox 1.18.2 , mtdwrap, uclibc, Linux Kernel 2.6.32.59_stm24_0211, ST drivers: embx.ko, embxmailbox.ko, ics.ko, ics_user.ko, lxload.ko, mme.ko, mme_user.ko, LZO Decompression Library 2.03, Decompression Utility
PORTS : 1 HDMI 1.2/1.3/1.4, 1 USB 2.0, SAT-IN & 2 Audio 1 Video Out , 1 Optical S/PDIF (for Dolby Digital Plus Audio ), 1 Digi Card.
I Found 1 UART PORT Which would be used while extraction of Firmware.
AFTER SOME REASEARCH I FOUND THAT IT HAS SIMILAR TO ARM-CORTEX-A9 AND MALI-400 GPU. (MAYBE I'M WORNG)
IDEA : It has a a Good processor and ram which can run as raspberry-pi os.
so we can repurpose it as a Media Center, Gaming Console, NAS, Smart Home, Small Server or a Mini Computer.
storage is low so we have to add some storage. I'm not sure how this is possible. except swapping the NAND flash Chip.
GOAL 1 : Extract Firmware and Extract Paid Decryption key which is use to verify the sat-in signals. ( a stb which don't required subscription to watch any tv channel )
i think they modified the software which capture the unencrypted signal and if we have a signal receiver then we are good to go. but for big companies wants to earn money so they added these barriers which needs decryption. and if the satellite is sending encrypted signal then we need to find the key. ( i know it's hard that's why we are here. I'll love to hear you thoughts on these)
GOAL 2: Change the Firmware and install Linux.
Goal 3: Find a way to use it as media server with increased storage and add a wireless module for WIFI access.
I'm not sure it is possible or not. but i think its possible. just think about it a small hardware can collect signal from satellite and decrypt the signals in HD with Dolby HD audio. we just need to find a way to access this.
I SHARED MY IDEA AND I DON'T KNOW MUCH ABOUT THESE.
PROBLLY I'M GOING TO ACCESS THIS WITH UART INTERFACE AND TRYING TO ACCESS THE BOOTLOADER.
OR MAYBE DESIGN A CUSTOM KERNAL.
I'M SEARCHING FOR COMPATIBLE FIRMWARE WHICH I CAN MODIFY AS I NEED.
EXTRA : I FOUND A SIMILAR STB WHICH USED IN RUSSIA "NTV PLUS SET TOP BOX" HAS SIMILAR PROPERTIES LIKE TATASKY HD BUT WITH EXTRA I/O PORTS.
THANK YOU. IF YOU HAVE ANY ADDIONAL IDEA THEN I'LL LOVE TO HEAR THAT.

This is probably the UART. You will most likely get a shell and U-Boot logs provided that it's not fused-off (ST microcontrollers can have debug interfaces fused off during flashing at the manufacturer)
How to find the pinout:
GND will have continuity with metallic parts of the board (heatsinks, HDMI ports, etc)
VCC will measure 1.8-5V DC depending on logic level
RX will not measure very much voltage
TX will go crazy during boot on an oscilliscope.
Try baudrate 115200 8n1

Well i don't have oscilloscope yet, soon I will try your guide, thanks for guidance. I will try to update upcoming experiments.

I think we can utilize the usb port on the back to add the external storage, as the usb port is used for storing the TV recording (as far as I can recall), and for the uart part, we can also use it for accessing root shell in the initial step, to figure out the operation method and framework.
I don't have any idea about the encryption keys, it would be cool if there's a way for that.
I have the same STB, would love to repurpose the old box, what's your progress on this so far ?
If you have a multimeter, you can check if the pins are for UART, RX voltage would be very low, TX voltage would be fluctuating upon boot, check continuity for GND with any grounded part like the HDMI port shield or the AV port silver port, VCC would be 3.3 or 5 volts
