B&O IR and Arduino
in General Discussion & Questions · Sept 10, 2014 10:17Yes the Arduino is great to made quick developments even if they have some hardware mistakes (my alarm system with GSM alert and my DMX smoke/fan control works with mega 2560 ;) ) Don't worry i will share the schematics …
B&O IR and Arduino
in General Discussion & Questions · Sept 9, 2014 18:55This is why i'm not using arduino ;) are you sure that the UBRR or counter compare interrupts + reload can't accurately create the 455KHz carrier? I'm working with my own microcontroller boards design and assembler / C++…
B&O IR and Arduino
in General Discussion & Questions · Sept 9, 2014 16:56yes the discrete receiver seems to be very sensitive but uses another component hard to find : the 455Khz bandpass filter. but it's available at farnell.
B&O IR and Arduino
in General Discussion & Questions · Sept 9, 2014 16:12Yes i've seen the old topic about datalink but I need to go further in the specs. about the TSOP7000 the lack of availability was why i've choosen the discrete way. ( it's an obsolete component and you only find new old …
B&O IR and Arduino
in General Discussion & Questions · Sept 9, 2014 13:08I'm actually working to build B&O receiver to control some kind of system with a B&O remote like a MP3 player connected by aux input to my beocenter etc... it's like a B&O receiver with relay output. Build an emitter is …

Beo4 Remote - works for about 24hrs and then stops
in Imported Content (Unmapped) · Sept 3, 2014 09:41Thanks Mika :) I think it's due to electrical stress. the pump charge constantly use the capacitor in the two polarities and that can cause some faillure ;) a drop can causse the faillure too (by cracks in the dielectric…
Beo4 Remote - works for about 24hrs and then stops
in Imported Content (Unmapped) · Sept 1, 2014 11:36I've got near the same issue with a faulty Beo4 bought from ebay for 20 euros. The current drain was too high (near 3mA) and after some work I found the culprits: one capacitor of the LCD pump charge was faulty. now the …
Beocenter CPU UVPROM binaries
in Imported Content (Unmapped) · Aug 31, 2014 22:12Hello and thank you for your help :) I need the binary I think because I will replace the UVPROM by an E²PROM so I must have the binary file to program the chip :)
Beocenter CPU UVPROM binaries
in Imported Content (Unmapped) · Aug 31, 2014 20:21Hello. i'm working to repair my beocenters (I have three of them 1 x 9000, 1 x 9500 and 1 x 8500 as I remember) I'm working on the 9500 at this time. the lithium battery is dead and i must replace it. when openning the C…
LC2 blocqued on
in Imported Content (Unmapped) · Aug 28, 2014 20:30can you take a picture (top/bottom) of the board? several things can cause such problem like the zero crossing detector / dead microcontroller / dead triac.
