Hat hier jemand Ahnung von #PCB Erstellung z.B. mit #EasyEDA oder generell? Ich habe ein Projekt mit dem #esp32 und verschiedenen Modulen, wie #TP4056, #MT3608 etc und würde die gerne direkt auf ein PCB anbringen lassen bzw. nachbauen, so dass sie bzw. der Teil den ich davon brauche fertig auf einer gemeinsamen Platte geliefert wird.

Телефон на 600 квартир

Приветствую всех! Когда-то давно попался мне на просторах вот такой мем: Посмотрел я тогда на всё это и забыл. А недавно, встретив его ещё раз, подумал: что, если попробовать сделать такой девайс в реальности? Как насчёт собрать такой телефон, по которому в самом деле можно будет позвонить? Именно этим-то мы сейчас и займёмся.

I built an Atari Punk Console on a #breadboard few days ago, and now I'm planning how to build a nice #enclosure for it.
I want to fit speaker, audio jack, salvaged #LiPo battery, #TP4056 charging and protection board, boost converter to get the 9 Volt, USB-C socket for charging, and of course some potentiometers, switches, and a minimized board for the #circuit.
Planning the #PCB layout was done using #KiCad, using SMD resistors.

I was testing my "5V #solar panel" using an adjustable load power tester.

The "MPP" seems to be between 400-500 mA, after which it would fail to charge the battery (voltage falls below 4.2V at ~440mA draw).

Now to figure out how to tweak the miniature R2 resistor on the #tp4056 board...

My #solar + #tp4056 + #lipo + #esp32 combo was having issues when I connected the esp32 to the tp4056 via crocodile clips for testing the thing out. It would drop voltage below 3V and brown out, rarely managing to boot.

It turns out all I needed to do was solder the damn power connection. Stable power delivery over night, and this is without any power optimization like deep-sleep, sending data every 15s.

It's alive!

My DIY outdoor weather sensor based on #esp32, #solar panel, #tp4056 battery charger with #lipo battery, #sht30 as the temperature+humidity sensor, #bh1750 as the light intensity sensor, and a voltage divider to monitor the battery voltage. All values are being collected by #esphome running on the esp32 and sent to my #homeassistant running on a raspberry pi.

Now to find a reasonable case for this and throw it somewhere in the garden within the reach of wifi...

The #TP4056 is an amazingly versatile chip, if you skip the USB port it accepts 4.5 to 6V, perfect for a small solar panel. It can then be used to power a microcontroler like an ESP32 that I plan to.

Inspired by my favorite guy with a swiss accent: https://youtu.be/37kGva3NW8w

However I should have checked my order - my panel easily saturates the 200mA limit of the component I got. And I don't have SMD resistors nor skills.

New blog post - TP4056 replacement PCB - I made a replacement PCB for the cheap TP4056 lipo charger units. I've added USB C CC resistors and made it easier to replace the Rprog resistor which sets the charging amp level https://facelesstech.wordpress.com/2023/04/11/tp4056-replacement-pcb/
