#Happy420 Day! Den Tag zum Anlass genommen, habe ich heut ein weiteres Development Release meiner #CanGrow Firmware zusammengeschnürt und den v0.2 Entwicklungsstand in den Git main gemerged, da dieser nun voll funktionsfähig, wenn auch noch nicht feature complete, ist :)

Neben einer aktualisierten Readme mit Git Projekt gibt es auch unter den Release prebuilt Binaries zum direkten Upload auf euren #ESP :)

Tiede korjaa omia ennakkoluulojaan. Tutkijoiden mukaan lapsuuden turvattomuus kehittää ESP, eli selvänäkökykyjä ainakin kaukonäkemisen osalta.

smol pcb to connect 4x analog capacitive soilmoisture sensors directly to an ADS1115. Hopefully handy for grow tents

One thing I should have added, will add in next revision: second I2C header to connect another sensor directly to the bus.

Nach einem Monat gibt es mal wieder ein kleines Update zu meinem #CanGrow Projekt. So langsam aber sicher vervollständigt sich die v0.2, das Dashboard funktioniert schon einmal zu großen Teilen, was ein recht großer Brocken auf der ToDo Liste war :)
Es können jetzt neben den bekannten Tachometern auch Liniengraphen angezeigt werden. der #ESP speichert dabei alle halbe Stunde für max. 2 Tage die Daten im LittleFS :)

heise+ | Unter 5 Euro: Pflanzensensor selbst bauen und in Home Assistant einbinden

Mit einem Sensor und einem Wemos D1 Mini lässt sich die Bodenfeuchtigkeit in einem Pflanztopf messen und per WLAN an Home Assistant funken. So gehts.

Why do all beginner #ESP #LED tutorials use a 220 or 230 ohms resistor when driving a red LED?

My calculations give 75 ohms to achieve 20mA. A factor of almost 3 is quite a large safety margin...

The last few years I built some controllers mostly based on #ESP using C++ open source projects.
I thought it would be nice to list them for those interested in #homebrew and #beer making.

I like the brew process but also the design and building steps of electronic equipment

1: brew controller designed by a fellow beer brewer. Controls temperature and steps during mashing. Touch screen and a control of the indcution cooker
2: a simple temperature measure and time (as backup when I remotely brew)
3: iSpindle to measure the progression in the alcohol during the fermentation
Now replaced by a device that utilizes bluetooth and qmtt and more because it resides inside a metal container
4: brewpiless, a controller for the fermentation chamber. It switches the cooling and heating to maintain a controlled environment

Below some prototypes, more to follow if there is interest with some links

XENSIV Angle Sensor TLx5012B (4.0.0) for avr/xmc/esp32/esp by Infineon Technologies

This library enables the Infineon XENSIV(TM) TLx5012B magnetic angle sensor.

Got my hands on on the still in dev #esp-32-c5 5G wifi capable devkit module! Took some doing, but after installing the latest espidf I was able to at least compile and run the simple wifi ecmaple and conect it to a 5G wifi network!!
