RISC V Raspberry Pi Zero, DIY Haptics, ESP32 and more!

eye squared sea according to wikipedia

One problem that Scottbez1 has run into with that programmable rotary encoder project is that it requires a very specific brushless DC motor that is now out of stock. He cannot replace it with just any BLDC because most suffer from undesirable cogging

The ESP32 articles were interesting.

I liked the tutorial format

I am playing with the Thingy:91 at the moment. A few small issues found so far, but a useful little dev system.

Just recently i rediscovered ESP32 and now I am so eager to use it for all my projects. I am just getting through all the different boards with it finding one that support micropython and is quite budget friendly as I want to do just simple single purpose build with each of them.

Cool to get riscv more mainstream...

i2s is not i2c, it is a standard for audio DACs

hey

Even if it has a Pi form factor, please don’t call it a Raspberry Pi. They won’t have the excellent ecosystem of The Raspberry Pi Foundation.

Trenton Computer Festival is definitely my summer viewing.

NEVER connect anything connected to the mains (unless FULLY isolated) to your body. Even if it's powered by USB and USB from computer, they can use a floating earth i.e. USB 5V may be one side +230V and the other side +225V so a relative voltage of 5V, but can be 230V relative to ground. 230V CAN KILL you. Current will take the route of least resistance (literally) and generally that's across the skin, so you might get skin burns, if it happens to pass across the heart, 9uA when it's in resting phase (S-T) will stop it PERMANENTLY. That's why defibrillator units are also complex heart rate (ECG) monitors as they can only fire when the heart is contracting ...
