After getting the Sound Synthesis by Terence Thomas, and seeing the PCB layouts provided, as well as seeing a need to make cheap PCBs for the Bastl Trinity, I thought it worth coming up with a basic kit of PCB etching
A friend asked:
is it possible to upload source code from chip to the computer?
If you need a vape device or supplies, then you can’t go wrong by visiting Vape Oon, in Leicester…
Plus a wrap up of the Heisenberg story, and turning 0 mg nicotine eJuice into something a little more useful. Continue reading Leicester vape
I’ve had my mod for a year and it was fine, then suddenly, during one vape session, mid vape it stopped and I got the Ohm to low message. I tried removing the tank, still got the Ohm too low message, instead of No coil message. Rebooted (i.e. power down, batteries out and in, and power on), still the same Ohm too low message.
Following on from Can an Arduino function as a DSP?, it is possible for the Arduino to make music – take Bytebeat, for example.
What is byte beat?
Bytebeat is a music synthesis technique that was discovered by Ville-Matias Heikkilä (viznut/pwp). Kragen Javier Sitaker has a good writeup on the subject. The way it works is that you generate a stream of 8-bit audio with the samples calculated by a function of sample index. This means that the song is defined by the function. In pure-form bytebeat, the function corresponds to a computer program that employs bit-wise and basic arithmetic operators, meaning that a small-sized formula would also have a small-sized implementation if realized in machine language or something like that. It may have been vital to Viznut’s discovery that he experimented with a low 8 kHz sampling frequency. With high sampling frequencies, the flat spectral envelope arising from bit-wise operations and numerical wrapping makes the sound thin and harsh. I regretfully admit that initially I had doubts that the methodology would be able to produce anything else than glitch-y noise, but it turns out that some formulas produce songs suitable for a wider audience.
A friend of mine asked if an Arduino could perform certain digital signal processing (DSP) tasks, such as the FV1 chip, see Spin Semiconductor FV-1. However the ATmega328, nor the ATmega2560 can do this, as they are 8-bit processors, and a faster chipset would be required (i.e. FPGA).
The ATmega chips struggle to control 3D printers at times and 32 bit microcontollers are becoming more and more popular. The Arduino Mega 2560 (i.e. ArduMega) was dropped from ArduPilot/ArduPlane/ArduCopter, due to its limitations, a while back, with v3.2.1 being the last release that supported the ATmega2560.
I also remembered that I saw a similar question on Arduino stack exchange the other day. Continue reading Can an Arduino function as a DSP?
I picked up an for Opcode Systems – Studio Plus 20 baht. No leads.
There is very little information about it, and not one photo, on the web.
