but the ESP32 has 18 channels
posting my esp32 project
ESP32 is great with IO, esp8266 wasn't that good, so attaching an arduino was oftenly a valid option
the problem was the actual ESP8266 chip had plenty of IO ports
but most of the breakouts didnt provide them
@Lj4IW9hY3JmTwb looks comfy
like both of these use the same chip
i like the wemos d1 series
ye those are pretty neat
going for the same stackable shield design as arduino uno
wemos started with something new now, x-series or something
seems neat af
that seems overpriced
esp32 should be ~$5 and about the same for the neopixel ring
the other parts are pennies
oh wait are those tiny displays
yeah, 2.9inch
because i didnt have enough to do already im attempting to build my own dual channel variable power supply
after i found a neat toroidal transformer for it
two 30V 4A coils and one 12V 0.5A coil
You can do 6 inch or 9.7 inch, but you need to roll your own controller
waveshare has a 7"
comes with a rpi hat, but can also be controlled by spi
>63$
whoa
do you guys make your own PCBs and if so which EDA software
pencil+paper
which chinese boardhouse accepts that :^)
or do you etch it yourself
rip one from a kindle and reveng the protocol
I've been using kicad and will probably end up with some $5 chinese board house because they can outperform anything i'll manage to pull off
etching seems doable but soldermask (and silkscreen but less essential) seem near impossible
Main disadvantage of a chineese board house is that you have to wait a month to get your boards. Also soldermask is doable with UV-resist.
