Bluetooth SPP – 01/12/2021 – write first draft
Spent some hours today working on getting the Arduino HC-05 running, and then testing it. I was able to connect the HC-05 through the Arduino to send serial hello world messages to my computer. Using the computer I am able to see the messages with the RFCOMM server through the command line. I am having… Continue reading Bluetooth SPP – 01/12/2021 – write first draft
Cymatics – 12/3/2020 – experimentation
More power, more amplifiers, more light… We have a ways to go here before having something of value, but further experiments will include our own coil winding to excite crystal activators, and an oscilloscope to observe sound quality in electronic form Things yet to come
Cymatics – 12/1/2020 – building the stand
Building a way forward to play frequencies through water and see these effects is non-trivial. First you must generate the sound. I have found a command in using Linux to generate pure tones. padsp signalgen -v -s 88200 sin 396 This command generates a 396 Hz frequency, sampled at 88200 Hz. I send this signal… Continue reading Cymatics – 12/1/2020 – building the stand
