UPS PIco HV3.0 documentation not on github: “03_0x38_W_UPS PIco HV3.0.pdf”

Posted by jpluimers on 2017/10/17

I ordered a UPS PIco HV3.0 A Stack 450 Plus and it arrived without any documentation on how to solder the parts together.

So I tried searching for them: https://www.google.com/search?q=UPS+PIco+HV3.0+A+Stack+450+Plus+installation+instructions which turned mostly github based URLs.

I learned there is a bit on github:

But despite code and documentation being there, no installation instructions on how to solder the stuff together.

Luckily, they responded quickly to my tweet So I got my “UPS PIco HV3.0 A Stack 450 Plus” @ModMyPi but no assembly instructions. Where do all the non-soldered parts go when using RPi3? and a quick respons thread revealing I needed 03_0x38_W_UPS PIco HV3.0.pdf which – TADAAAA – is on Google drive and on the forums at [WayBack] UPS PIco Firmware Update & Troubleshooting : Technical Support

So despite github providing an excellent platform for discussion and storing documentation, something archaic like a forum is used to store data in a disorganised way.

Too bad, as the document itself is 100+ page of invaluable documentation.

So in case of future bit-rot, here are the links:

Some ChromeCast URLs

Posted by jpluimers on 2017/02/01

I need to check these against a Chromecast v2 as the below URLs are from a v1 device:

More is possible by using cURL: Chromecast Hacking Has Begun | fiquett.com

sleep 8h; while true; do
curl -H "Content-Type: application/json" http://192.168.71.113:8008/apps/YouTube -X POST -d 'v=somevideo';
done

Some notes and links on hacking a Philips TVs TCP ports

Posted by jpluimers on 2017/01/25

In my case this is about a Philips 42PFL7676H TV, but this likely applies to many Philips TVs from the 2009-2012 era.

According to nmap, these ports are open:

PORT STATE SERVICE REASON VERSION
1925/tcp open unknown syn-ack
2323/tcp open 3d-nfsd? syn-ack
49153/tcp open upnp syn-ack Philips Intel UPnP SDK 1.4 (Philips Smart TV; UPnP 1.0; DLNADOC 1.50)

TCP port 1925 is actually implementing the jointSPACE REST API over HTTP which has some nice documentation (also locally on your TV).

PCremote implements this and is easy to install: just download (or git clone) the html locally or to a web-server and try it, or even easier: browse to the www.netdata.be/tv site. You can even use it on your Raspberry Pi. There is also support for jointSPACE it in agocontrol.

Two nice threads about it from the Philips support forum:

TCP port 2323 seems to be the voodooport which should enable you to do DirectFB Voodoo.

Jean-Marc Harvengt (software engineer at Philips) showed a nice demo (see video below) on using VooDoo. I wish he had published the source code.

TCP port 49153 also hosts an HTTP server. The base URL I could find information about is 192.168.71.115:49153/nmrDescription.xml It seems that nmrDescription.xml has to do with DLNA and upnp.

Later on I found that my brothers 32PFL7675H TV should also support JointSPACE, but that it had to be activated:

AFTER upgrading to the new firmware, jointSPACE NEEDS TO BE ACTIVATED by entering the following digits sequence while watching TV (WatchTV activity): “5646877223”

Source: jointSPACE TVs Developers

Before activation, only port was open 49153. After that, port 2323 was open as well. But the www.netdata.be/tv app doesn’t work on this TV. This does work however: Philips MyRemote – Android Apps on Google Play

Replace Boxee by Raspberry Pi as most TV support doing video+USB keybard over HDMI

Posted by jpluimers on 2016/02/22

If for instance your Boxee gets old or breaks down, you can use a Raspberry Pi as a replacement with Kodi as media player.

This combination will understand the Video+USB over HDMI which most TV supports officially named HDMI-CEC , but most vendors “invented” their own names (see list below).

The core is the kodi support for CEC.

Basically it comes down to using three cables going to the Pi: Power from TV (or some other source), HDMI to TV, and wired Ethernet. And a distribution for RaspberryPi containing kodi will work, for instance from OpenELEC Mediacenter – Download: Raspberry Pi Builds

Chad MILLER has more details on how to get this to work: My Boxee box is getting old, but I knew of no replacements. The problem is I …

Names known for HDMI-CEC via Wikipedia:

Anynet+ (Samsung), Aquos Link (Sharp), BRAVIA Link and BRAVIA Sync (Sony), HDMI-CEC (Hitachi), E-link (AOC), Kuro Link (Pioneer), INlink (Insignia), CE-Link and Regza Link (Toshiba), RIHD (Remote Interactive over HDMI) (Onkyo), RuncoLink (Runco International), SimpLink (LG), T-Link (ITT), HDAVI Control, EZ-Sync, VIERA Link (Panasonic), EasyLink (Philips), and NetCommand for HDMI (Mitsubishi).

Because of the naming, turning on CEC can be confusing: How to Enable HDMI-CEC on Your TV, and Why You Should

USB Typewriter — Classic Typewriters for the Digital Age (for mechanical typewriters, not electrical ones)

Posted by jpluimers on 2014/03/19

Nicely done: the USB Typewriter — Classic Typewriters for the Digital Age, as they can do almost all keys a PC keyboard can do see the USB Typewriter — FAQ using a mechanical (not electrical!) typewriter.

Basically the opposite of  the IBM Selectric Computer Terminal, the Daisy wheel printing, the IBM 1050 system, and the IBM 2741 Console.

Note the kits (there are both soldering and non-soldering versions) are mostly aimed at models that once were popular in the USA, so for manufacturers like Adler there are no guidelines (but the existing guidelines for soldering and for non-soldering probably work fine).
