ESP32-Cam / .ino / Port forwarding / “Solar”-category !!..

Kommentar hinterlassen

so, 😉

have now the time to get a little bit more “in-depth” with the ESP32-Cam..You can get it meanwhile for 5-6$ from Aliexpress,Bangood etc..(LINK,LINK)

u need an FTDI-programmer for it of course, 1,50$, Ebay->(LINK)

a very good tutorial about setting up the ESP32-Cam, how to connect to the FTDI-programmer + sketch is here->https://randomnerdtutorials.com/esp32-cam-video-streaming-web-server-camera-home-assistant/

the sketch is also very “easy” (see on randomnerdtutorials) and for “flashing” u only need to set a jumper on IO0+GND (and remove it afterwards of course 😉 )..The .ino/sketch is also here->(LINK)

the picture-quality is a little bit better that u might expect in the worst case 😉 and now i use the ESP32-cam directly over (DHCP)-WLAN connected and display it in a browser (simple IP-adress in the bar) or via some dyndns-provider (use here spdyn.de in Germany)..

u only need to port forward (90 to 80 for example) it directly to the device..

very nice thing, use a raspberry pi zero wh as a webserver, mqtt-broker “in between” and will also use then some ESP32 for solarpanel-control/measure the current from the batteries and display it on a website/handy etc..

more to come..also ordered some “step up module” to easier power them with 5V/2 cables”, Ebay,->(LINK)

by that i made a new “category” (on the right)->”SOLAR” 😉 ..i will post there anything about 5V/12V solar-panels, autotracking them etc. !! all with some Arduinos,ESP32,Raspis etc..very much more to come,

(above picture + description is from : http://b04forum.dl3ndd.de/viewtopic.php?f=18&t=365)

but many greets from here !! 😉 (but no worry->essabre-90xx-rpi.sfb2.com will stay absolutely more hifi-related !! 😉 )

DIY-DAC: Telekom Media Receiver 303A as case/with 12V/3A power supply->as audio-streamer with Rpi4 + XMOS-USB-bridge + ESP32 as display-controller..

i´ve found a few days ago some “withdrawn from service” 😉 Telekom (uarghh ;-( )  Media Receiver 303A->was first interested in the internal HDD->500GB Seagate, but have seen then this has also a built-in 12V/3A power-supply and its from the dimensions almost ideally as some Raspberry Pi4-ES9038Q2M-audiostreamer !! (not soo big) 😉

Display-wise its a little bit limited (due to the available space (height)) in the front, but some LCD1602 will maybe do it fine..

found then an easy way to connect some to an ESP32 via I2C and via some “web-remotes” (see other posts here “Project-1” etc..) we can select via some photocoupler/relais the inputs of the ES9038Q2M (Coax,Toslink, I2S/USB), adjust the hardware-volume, filter-selection and so on and can display the settings on the display/LCD1602) !!

so far so fine, but this is a heck of a lot work to do !! 😉 ..

(i´ve planned to use Volumio on the raspberry ->easy controlling via the web-interface, DLNA-capable, MPD etc..)..

as said, here at first testing-out some aspects/parts for it and a first result by example is that these 3A makes the “blue” ES9038Q2M absolutely a little bit “airy(ier); had before some 2A power supply (12V)..

by that the “Leaf-XMOS-USB-bridge” (->http://essabre-90xx-rpi.sfb2.com/?p=2066) is better than first thought..

+ also my new “ESP32” will come to a new life 😉  (not to mention the Raspberry Pi4 2GB)

makes really a lot of fun here, and i will inform you about some further improvements !!

greets for now !! 😉
