  • Re: Using a raspberry Pi as a DIY equivalent to Logitech Harmony

    I haven't read through the full description of the data link info, but one line said it follows the same structure as the IR codes. To handle something like IR or the databus, you need to be doing real-time processing of the signal - while that is probably possible with a Pi, its a lot easier with an arduino as you are working at much lower level - essentially a big loop, and its happy doing that uninterrupted 24x7. So I'd suggest using an Arduino for handling the bus interface, and then

  • Beolab 8000 troubleshooting

    One of my Beolab 8000s stopped working. It has the red LED, but won't go green. I took it apart and found the foam had turned to mush. It was bad over what I assume is a thermocouple to measure the heat of the heatsync.Cleaning it all off and assembling on the bench, it all worked (yay). But after I re-assembled it, I'm getting the red LED of death. It may not be what I thought was the problem. Is there a guide of what to check for? I am handy with a soldering iron, multimeter and have a

  • Beolab 8000 grommet

    One of my beolab 8000’s stopped working, it would just show the red LED. Dismantling it showed that the foam had never been changed and had turned to mush, corroding the contacts for the thyristor checking the temp of the heat sink. Cleaning that up, it now works on the bench. As a refurb is in order I have cleaned it all up, and ordered new o-rings. However there are also rubber grommets that seal the cables between the main cavity and the lower cone. They are not in great shape - does anyone

    [quote user="djmp"] Thanks samsp! I got the buttons and also LED control going. For IR I do notice that I’ll get occasional misreads of the IR remote, incorrect code reported. Maybe that’s to be expected? [/quote] I have a feeling that the output of the IR Receiver is pretty noisy. I looked at the output with a cheap USB scope, and it seemed to have quite a lot of flicker in it, even when no signals were being received. Is this coming back as misreads in the serial data over

    I'd love a copy of the LED code, I have tried to set the LED state in the past and just seemed to hang the I2C communications. It would be nice to have a flash when a command is received, and also during startup. It is slick the way the arduino fits in the back, and turns a pretty proprietary device (B&O remotes) into something that can work with all sorts of home automation. Are you using a PI or something else at the other end of the USB?

  • B&O integration

    Late last year I moved back to the Seattle area and bought a new house. As usual the builder did a big fireplace, so if the TV were to be mounted above it, the base would be at 5ft high. So I mounted to the side of the stairs. This had the added benefit that the equipment could go under the stairs, all nice and hidden. The more astute will notice that its not a B&O TV, the only B&O equipment are the speakers, remote and IR receiver. I use a BeoRemote 1 to control everything via the puck on

    [quote user="djmp"] Thanks! Should have been more clear in my question though. I have the IR codes via USB and thanks for the remote control mappings. I'm talking about accessing the LEDs and the Timer/Play/Up/Down buttons on the eye. I'm guessing that's i2c coming out of the TX/RX connections on the eye? Haven't hooked them up yet to the Arduino but was wondering if someone had. [/quote] With the above arduino code, this part: else { uint8_t value = PCF_20.read8(); uint8_t

  • Re: Using a raspberry Pi as a DIY equivalent to Logitech Harmony

    [quote user="djmp"] Thanks to crossbytje I have an Arduino Nano running and reporting back IR codes with GND/5V/IR Signal connected (see https://forum.beoworld.org/forums/p/16023/138995.aspx for wiring). I have an IR eye with a 5 wire connection - the other two are TX/RX I believe - would like to get them hooked up. Right now I don't have the eye LEDs or local buttons responding - any idea on how to make that happen? Not sure of what protocol is going on via TX/RX. --- Miniterm on

  • Re: Using a raspberry Pi as a DIY equivalent to Logitech Harmony

    I have the receivers that use I2C (they are labelled with timer, vol, play/stop). You can supposedly use commands with the I2c device, a PCF 8574T, which is a TTL expander, to set pins for input or output. I have only gotten output to work - aka reading the buttons. My wiring is: viewed from screw side of connector of IR puck: Gnd, +5V, IR -> D3, SDL -> A4. SCL -> A5. ---- Arduino code --- #include <Commands.h> //#define PCF8574_LOW_MEMORY #include <pcf8574.h> #include <Beomote
