    Hi,
    We have a USB-To-RS232-TTL-USB-To-COM-Serial-Adapter-Cable-Module-PL2303HX-Converter/ cable that makes use of a prolific chip that is not compatible with windows 10. Would the FTDI 3.3v be a good replacement for this or can you suggest any other replacements that you may have in stock.

    Regards,

  11. Nick - Wednesday, 13 March 2019 on blog post Hacking a Mitsubishi Heat Pump / Air Conditioner
    Thanks very much for this guide.

    A few issues I had:

    MSZ-GE35VAD unit

    1. Flashing lights
    I thought I had caused some damage installing the connection. The issue was that the lights flash when you have removed the vanes and the unit won't work until the vanes are re-installed.

    2. CN105 pinout
    I assumed the 2nd picture showing the pin-out was orientated as if looking at the board when you open the unit. I based this assumption on the 3rd picture, showing the cable plugged into CN105 - I thought the colours followed the computer convention of red = 5v, yellow = 12v (I tend to do this in my projects), black = ground. So I thought it was RX, TX, 5V, GND, 12V from left to right when looking at the board in the aircon. In fact it is 12V, GND, 5V, TX, RX (from left to right).
    Took me a while to work this out - I'd initially only hooked up 5V, but the LED on my micro was dim and I thought there must be insufficient supply and so hooked up 12V with a voltage converter - still no good. Eventually checked the pins with the multi-meter...

    Thanks again for working this whole thing out. Hopefully my experience can help someone else who runs into similar issues.

  22. Chris Nisbet - Friday, 01 February 2019 on blog post Hacking a Mitsubishi Heat Pump / Air Conditioner
    FYI - I've been doing a bit of work making my own application to control these heatpumps. It's written in C and I used SwiCago (https://github.com/SwiCago) code as a starting point.
    For various reasons, I wanted to read/write the settings using UBUS calls. That means it's a little bit more involved getting everything to build, but it's not too tricky.
    I'm not too sure what, if anything, I'll do with this, but the basic idea was to eventually put the app onto a raspberry pi, plonk an XBee on the top, install another XBee inside the heatpump, and go from there.
    I have the application running on my dev system (using a USB adaptor to the XBee), and it seems to work a treat. I was thinking of eventually connecting to multiple heatpumps using multiple XBees in API mode, but I'm not there yet.

    Note that it doesn't add any functionality as far as the protocol goes - It just supports the same sort of stuff that the SwiCago code does.
    Also note that I wasn't trying to keep the code tiny.
    Although controlled using UBUS calls, it shouldn't be that difficult to remove the UBUS support and use some other interface.
    Anyway, the code is here
    https://github.com/ChrisNisbet01/Mitsubishi_heatpump

    Required libraries (build/install these first)
    https://github.com/ChrisNisbet01/libubusgpio (to ease the pain of adding the UBUS support)
    libjson-c: https://github.com/json-c/json-c.git
    libubox: git://git.openwrt.org/project/libubox.git
    libubus: git://git.openwrt.org/project/ubus.git
    I don't remember having any great difficulty building/installing those libraries.

    If it's helpful to anybody, great. If it doesn't work for you, bummer.

  27. Rudi S - Friday, 21 December 2018 on blog post Hacking a Mitsubishi Heat Pump / Air Conditioner
    Hi guys,

    Greetings from Belgium.
    I have successfully managed to implement Al's solution on 1 of the 3 of my units (2 MSZ-SF's and 1 MSZ-FH) by just using an ESP-01 and a 3.3v-5v level shifter.
    It is also working nicely in Home Assistant too!

    I have one question at the moment, is it possible to use an external thermometer rather that the internal one?

    Thanks for the great work!!

    Cheers,
    Rudi.

    Hi, seems Panasonic air-water heat pump has same connector, just different pin placment for rx tx and etc. I figured out all pins, tried to connect to my laptop ant monitor UART, but I doesnt get any data. Should I send some magic numbers to get communication working? Any hints how to figure out?

    Hi Aaron,

    Yes we will have stock of the new generation 5 version of the HDHomerun Connect Duo before christmas, probably in the next few weeks.

    In case you're wondering, there's no functional difference between the models so if you're wanting one then the generation 4 on this page is an excellent deal.

    Cheers,

    Hadley

    Greetings,
    We are planning to add RockBLOCK 9603 - Iridium SatComm Module to one of our products. Currently we are still in the R&D stage and we need to purchase the module for testing.
    I was wondering if we need to prepare any licenses, certificates or forms before purchasing the module.
    I also would like to ask if there is any specific recommended external; SMA antenna to be used with the module?
    please advise
    looking forward to hearing from you soon

    Hi, I'm running a Raspberry Pi 3b as a ham radio node/ repeater controller. It's running the Hamvoip Asterisk Arch Linux software. I'm trying to get my DS3231 RTC up and running with no success. I tried using the script from the following site...

    https://gist.github.com/grubernd/aed721614b36aaa31fd97ef5ab1ec6be

    when I run hwclock I get this...

    hwclock: Cannot access the Hardware Clock via any known method.
    hwclock: Use the --debug option to see the details of our search for an access method.

    The clock doesn't get detected. I tried your instructions. No luck. I can post the script and replies if that would help. I have two clocks and neither one works. Any help would be greatly appreciated. Thanks in advance, Vendel/ K2DSI.

    You could do that with an Arduino or similar, we're more set up with parts and things for people to build their own controllers and so don't have anything off the shelf that will do that unfortunately.

    Well, you didn't have to mount all the SMD components I assume. You forgot to quote the rest of the paragraph:

    "Each order comes with one assembled RTD amplifier breakout board. Also comes with two 2-pin terminal blocks (for connecting to the RTD sensor) and pin header (to plug into any breadboard or perfboard). A required PT100 RTD is not included! (But we stock them in the shop). Some soldering is required to solder the headers and terminal blocks to the breakout, but it's an easy task with soldering tools."

  46. John M Clayton - Wednesday, 19 September 2018 on blog post Building 100 Arduino Vacuum Pressure Gauges
    Hello Hadley. I have researched this further and it WILL work for a NPWT vacuum pump for treating wounds. My Orthopedic surgeon, and other Doctors go on "missions" regularly and would Love several of these made. I would be happy to do this for them. I was wondering if you could post a link to your Eagle PCB files and also a link to the Arduino code you used? That would be extremely helpful so I would not have to re-invent the wheel you've so wonderfully already designed. After I have the boards made and soldered up, I will send a link to a picture of them and a write-up of the project they were used for. Also, the vacuum version of the sensor is MPXV5050VC6T1 and is made by NXP USA for about $10 each. With 0 kPa vacuum on th port, the signal out to the Arduino would be about 4.96 VDC. At -50 kPa that signal is about 4.95 VDC, so, it would be 90 mV per kPa! That makes the math in the Arduino sketch so easy! And, it can be output and easily displayed on a small OLED display. Also, just doing math in the sketch, the kPa can be converted to in Hg; mm Hg, or even PSI! the user would turn a rotary encoder to select what units they want the reading in and then use an up and a down push button to set the desired setpoint of the vacuum they would like to maintain.

    I figure if I used new Atmel chips and program as you did with bootloader and code copied from one prototype, it would be very quick to mass produce and the cost would be, roughly about $30 per board. That is amazing. The Doctor said he can find donors to buy the parts. Thank you for designing such a wonderful board!

    Kind Regards,
    John

    I am making a Negative Pressure Wound Therapy (NPWT) vacuum pump. This Freescale MPXV5050 and arduino seems PERFECT? Do you offer these boards for sale? Maybe just the PCB and a bill of materials. I can solder components myself. I can take the output of the pressure sensor to an Arduino Nano analog input and, in the code, provide an on-off output signal to turn a vacuum pump on and off at a specific vacuum level.

    Currently available NPWT pumps cost over $2,000!!! I had one rented from a medical supply house and an 18 inch long incision was healed completely in less than 4 weeks! I had a hip replacement. I would LOVE to make these for instances where war or other major catastrophes can help injured people heal faster.
    One question... if the Freescale MPXV5050 is a PRESSURE sensor, does it also register NEGATIVE pressure (vacuum)? Typically a NPWT pump is set to around -110 mmHg (or -.146 BAR or -2.127 PSI). Thanks for any help! email me if you post your answer here on your blog mankey1960@gmail.com
