ISSUE: Use two BME280 sensors on the same I2C bus.
AFFECTED DEVICE: The bread board of type GYBMEP / violet color / one mounting hole / 4 pins has the default I2C address 0x76
PROCEDURE: Please orient the sensor with the connector holes downsides, mounting hole upper left side, sensor to the upper right.
I have enclosed the sensor with a sheet of kitchen aluminium foil to protect it from the vapours emittet by the soldering process.
Remove the bridge between the two left solder pads (of a total of three pads) with a knife, and connect the two right solder pads with a bubble of solder.
REMOVE the Al foil sheet before connecting the bread board!
TEST: Test the i2c address e.g. with the arduino script „i2c_scan“ which will send the addresses of all existing/recognized i2c devices from the arduino via USB to the serial monitor.
Some products are really exceptional especially when it comes to the bang-per-bucks-ratio.
One example are the Amaran/Aputure LED photo lights of type AL-H198C, a ~600 lumen battery operated LED lamp with controllable color temperature and brightness. With only one drawback: The potentiometers for the control of both parameters are (1) fiddly and (2) indistinguishable with tactile sense only.
After collecting some experience with loudspeaker chassis I owned and used for two decades I longed for upgrading the chassis. I always dreamed about a single speaker approach – the ideal point source.
A tube-shaped speaker chassis is predestined for such an approach but is always limited in terms of frequency range – the british company KEF has invested decades of research to overcome this limitation: The solution is a two way system with a centered dome speaker for the high frequencies …
