#arduino camera wifi

[myfootyrthroat]

We're looking at making/buying a non-cloud doorbell camera for the house. I'm not afraid of working with an Arduino/Rasp Pi, etc if necessary, but obviously if I could just buy something affordably, I'd rather do that. Basically something where someone could ring it and it would ping people on the local wifi (or maybe through an API like Adafruit IO, but not Amazon, etc). Anyone have any recs?

(@robustcornhusk this seems especially up your alley)

AH I REMEMBERED WHAT I WAS GONNA SAY EARLIER but it's kind of stupid, lmao.

So my partner is getting into brewing beer and I got them a Tilt, which is a Bluetooth hydrometer. It measures specific gravity and temperature, which are things you want to know so that you don't kill your yeast or whatever. Except the sensor's Bluetooth range is super short, and it basically runs via a phone app, and the temperature we're logging currently is the crawlspace, accessible via the staircase closet. So they were like, wait, what do we do about this, because I can't leave my phone in the closet, that's my alarm clock.

In a kind of ridiculous turn of life imitating art, I was like, hold up, I got just the thing right at my desk. Bam. Old phone. We just needed to scrounge up a charger because the battery is so dead that after charging just enough to power on it claimed it was at 53% (to be fair to it, there is a very real chance that it's correct, and it just holds no charge at this point so the capacity is just THAT low) and now it lives in the closet logging sensor data.

And I was like, you know...didn't I just solve a major story detail with a much larger version of this...yeah, no, this is all vaguely familiar somehow, power supply issues and all. Kind of cool that the concept works though. Kind of weird that it came up at all?

We are not gonna talk about the fact that I still have at least two more ancient-ass phones in a drawer where that came from because look, man, sometimes you just need a camera/mic/mini computer with Bluetooth and wifi that fits in a pocket, and people just get rid of these things, but not me. I actually could build a shitty security system out of them if I was reaaaally inclined. I mean. I'm not. But it's technically possible.

For real though, If I pick up any stupid maker projects I still high-key am thinking about slapping Bluetooth into a necomimi headset and running that through an Arduino and learning to code just enough to let me skip songs/change the volume on Spotify with my brain, because it's entirely doable, and I mean yeah I could do that on my phone remotely too, but that's not funny, now, is it. I'm just not sure it's $350+ of parts funny. Kind of a big investment just to prove the point that haha look I am the extremely ADHD type of lazy where I would rather solve a problem via the most convoluted and complicated Rube-Goldberg type ass machine way possible rather than just perform a single simple action.

YEAH I'VE BEEN THIS SCATTERED ALL DAY AND I REALLY SHOULD GO TO BED SHOULDN'T I. I started playing Satisfactory. Mistakes were made. I'm going to dream about conveyor belts again and I did it to myself...

Raspberry Pi Pico: Programmierung und Entwicklung mit der Arduino IDE auf Linux

In diesem Artikel zeige ich dir, wie du den Raspberry Pi Pico in der Arduino IDE unter Linux programmieren kannst. Gemeinsam werden wir die Schritte zur Einrichtung und Konfiguration der Entwicklungsumgebung durchgehen, um sicherzustellen, dass du problemlos mit der Programmierung starten kannst.

Den Raspberry Pi Pico gibt es derzeit in zwei Versionen, zum einen mit und ohne WiFi und neuerdings sogar mit Bluetooth Support. Der kleine Zwerg auf dem nachfolgenden Bild ist der XIAO RP2040 welcher auch mit dem RP2040 Chip des Pi Pico daher kommt nur Bauartbedingt weniger Pins als der große hat.

Mikrocontroller - XIAO RP2040 & Raspberry PI Pico Die Inspiration für diesen Artikel stammt von einem treuen Leser meines Blogs, der aktuell Schwierigkeiten bei der Einrichtung und Konfiguration seines Raspberry Pi Pico hat. Mein Ziel mit diesem Beitrag ist es, ihm und anderen, die auf ähnliche Herausforderungen stoßen, zu helfen und eine Lösung für dieses Problem anzubieten.

Anschluss & Einrichten des Raspberry Pi Pico unter Linux

Zunächst schließen wir den Raspberry Pi Pico an einen freien USB-Anschluss an, dieser sollte dann auch erkannt werden. oem@anna:~$ lsusb Bus 001 Device 002: ID 8087:8000 Intel Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 002 Device 002: ID 0bda:57bc Realtek Semiconductor Corp. USB Camera Bus 002 Device 003: ID 2e8a:0005 MicroPython Board in FS mode Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub oem@anna:~$ Nun müssen wir dieses Board in den Bootloader Modus starten, dazu trennen wir zuerst das USB-Kabel wieder vom PC und drücken den kleinen, weißen RESET-Taster auf dem Board und verbinden dann wieder den Raspberry Pi Pico (mit gedrückter RESET-Taste) mit dem PC. Im Dateimanager sollte dann ein neues Laufwerk "RPI-RP2" sichtbar sein. In meinem Fall hatte ich sogar auf dem Desktop noch ein zusätzliches Symbol für dieses Laufwerk erhalten.

Laufwerk des Raspberry Pi Pico unter Linux

Installieren der Treiber für die Arduino IDE unter Linux

Jetzt wechseln wir zur Arduino IDE, in meinem Fall hatte ich bereits die Version 1.8.18 auf meinem Linux Mint 20.2 installiert, welches ich weiter nutze. oem@anna:~$ lsb_release -a No LSB modules are available. Distributor ID: Linuxmint Description: Linux Mint 20.2 Release: 20.2 Codename: uma oem@anna:~$ Schritt 1 - Erweitern der zusätzlichen Boardverwalter-URLs Als ersten Schritt müssen wir der Arduino IDE eine neue Quelle für Boardtreiber angeben, dieses wird im Dialog "Zusätzliche Boardverwalter URLs" gemacht. Du erreichst diesen über "Datei" > "Voreinstellungen" > "Zusätzliche Boardverwalter URLs"

Dialog "Zusätzliche Boardverwalter-URLs" in der Arduino IDE Hier fügen wir die nachfolgende URL hinzu und betätigen die Schaltfläche "OK" https://github.com/earlephilhower/arduino-pico/releases/download/3.4.1/package_rp2040_index.json Schritt 2 - Installieren des Boardtreibers über den Boardverwalter Nachdem wir die neue Quelle für unseren Boardtreiber angegeben haben, können wir in den Boardverwalter wechseln. Diesen findest du unter "Werkzeuge" > "Board: xyz" > "Boardverwalter...". In diesem Dialog suchst du nun nach "rp2040" und wählst die Schaltfläche "Installieren" am Paket "Raspberry Pi Pico/RP2040" aus.

Boardtreiber "RP2040" im Boardverwalter Es werden jetzt diverse Dateien heruntergeladen, die Verbindung war in meinem Fall nicht sehr stabil und somit musste ich diesen Vorgang insgesamt dreimal starten. Das gute war jedoch, dass der Installer am letzten Schritt weitergemacht hat, somit dauerte dieser Vorgang nur wenige Minuten. Schritt 3 - Auswahl des Boardtreibers Wenn der Boardtreiber für den Raspberry Pi Pico erfolgreich installiert wurde, dann wählen wir diesen aus "Werkzeuge" > "Board: xyz" > "Raspberry Pi RP2040 Boards (3.4.1)" aus. In meinem Fall habe ich einen normalen RP2040 also ohne WiFi Support gewählt.

Unterstützte Boards des Treibers Im nächsten Schritt müssen wir noch sicherstellen das, der korrekte Anschluss gewählt ist, hier muss "UF2 Board angewählt sein.

Auswahl des Ports für den RP2040 Die Konfiguration des Boards habe ich nicht verändert und mit dieser hat der Upload eines ersten Sketches auch funktioniert.

Konfiguration des Raspberry Pi Pico in der Arduino IDE

Testen der Installation & Konfiguration mit einem kleinen Sketch

Nachdem jetzt alles eingerichtet ist, testen wir unsere Installation & Konfiguration einmal. Dazu schreiben wir ein kleines Sketch welches uns lediglich die Textzeile "Hallo Welt!" auf der seriellen Schnittstelle ausgibt. void setup() { // put your setup code here, to run once: Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: Serial.println("Hallo Welt!"); delay(500); } Der Upload-Button führt dann nachfolgende Schritte aus: - prüfen & kompilieren des Codes, - Umwandeln in eine UF2-Datei, - suchen nach Laufwerken / RP2040 Geräten, - kopieren der erzeugten UF2-Datei auf das gefundene Laufwerk

kleines Beispiel Sketch zum Testen der Installation & Konfiguration Wenn wir uns nun die Ausgabe im seriellen Monitor anschauen möchten, erhalten wir eine Fehlermeldung, denn im letzten Schritt wurde der RP2040 neu geflasht und dann mit einem neuen Anschluss eingebunden. Diesen Anschluss müssen wir dann zunächst unter "Werkzeuge" > "Port" auswählen.

Auswahl des neuen Anschlusses nach dem Upload einer ersten UF2-Datei Nun können wir wie gewohnt den seriellen Monitor öffnen und sehen unsere Ausgabe "Hallo Welt!" (hier zusätzlich mit einem Zeitstempel).

Ausgabe der Textzeile "Hallo Welt!" im seriellen Monitor der Arduino IDE

Abschluss & Ausblick

Ich habe dir jetzt gezeigt, wie du deinen Raspberry Pi Pico unter Linux einrichten und ein erstes Sketch auf diesen speichern kannst. Die Information dazu musste ich jedoch zunächst auch erstmal suchen, dass dieses nicht so einfach ist. Hier habe ich mir als Quelle den Beitrag Raspberry Pico mit der Arduino IDE programmieren vom Heise-Verlag genommen. Im nächsten Beitrag würde ich mir mal den Raspberry Pi Pico mit WiFi und neuerdings auch Bluetooth Support nehmen und testen, wie man dort einen kleinen Webserver programmiert. Read the full article

That Optor thing sent me down a rabbit hole (the rest of the site)

The author invented an LED data transmission system that allows a minimum of 10Mbps over 1.4km, and because it doesn't use lasers, there's minimal regulations on it. He has very detailed guides that include vocabulary and pictures on how to make the physical devices (just plug ethernet into the box and you can ping your neighbors).

But anyways, it got me to thinking about your idea to make a book broadcasting station. Phone cameras can record infrared light, so what about infrared LEDs that broadcast data anyone with a smartphone app can access? You'd be limited to the 24FPS of the camera, which would be 3 ASCII characters per second. A book would take 1/3 of a year to download, but a smaller essay or article would take tens of minutes.

Transmitters could be set up in busy areas surrounded by office windows or food places and people in the know could just use their camera app to look around for blinking infrared lights, then face their cameras toward it while they eat or work and read the articles later.

You could even add a wifi module and have it set up as an open access point with a webpage that allows text uploads (with a filesize limit). People could anonymously upload files, and they'd be broadcast in order.

(Could also skip the LED part and just make little arduinos for $40 that access points with write-only file servers so anyone could leave pdfs or recordings. And then autodelete files after # days. Could run off a lithium battery and would be difficult to find the transmitter)

Hm, I don't know about using infrared. I'd much prefer radio waves, which (I believe) would allow a more usable speed of ~27 bytes/ASCII per second over regular radio. This would mean an average book would take just under 4 hours.

I do like the last paragraph, that's an interesting idea. Analogue pastebin...

If that is your case, try installing older versions of the app. Even in some rare cases, the re-install step also don't work.iOS usually provides an option to restore settings and content from iCloud backup, if you've enabled it previously. Finally, if you can't fix it with anything, you may need to uninstall the app and re-install it.After that put it to charge, and press the power button. If none of the above working, you can wait till your phone battery drains and it turns off automatically.Press the power off button for few seconds and then choose restart from the menu to restart your device.Now you can try opening the app, it may work fine. Then you close the app that has this issue. You just need to press the recent applications menu (usually the first left button) in your phone. Most of the times, it might be a temporary loading issue.Usually when you open an app, you will see a black screen for few seconds and then app will crash with or without an error message. It is one of the most common problem in mobile phones and tablets. jules.dukers liked DIY Beam-on-Target Fusion Particle Accelerator.Common PixelStick App Problems and Troubleshooting Steps ✅ I'm getting black screen / white screen (blank screen) when I open PixelStick?.jules.dukers liked Web security everywhere.Florian Festi wrote a reply on Boxes.py.kelvinA wrote a comment on project log Project Log 4: Not So Much Fun With FEA.micl has updated the project titled PicoPad.Charlie Lindahl liked Solar Powered WiFi Weather Station V4.0.Steven J Greenfield wrote a comment on Metrix Create:Space.Elliot Williams on As Europe Goes To LEDs, Scientists Worry.Darren on Better Mousetraps (or Screw Drives) Don’t Always Win.thoriumbr on Raspberry Pi Grants Remote Access Via PCIe (Sort Of).one on Mechanical Color Picker Types Hex Codes For You.70sJukebox on Raspberry Pi Grants Remote Access Via PCIe (Sort Of).Elliot Williams on 3D Printed String Vase Shows What’s Possible.Eric Chapin on Mechanical Color Picker Types Hex Codes For You.daveboltman on It’s Pi All The Way Down With This Pi-Powered Pi-Picking Robot.Alexandre on Mechanical Color Picker Types Hex Codes For You.Hackaday Podcast 185: A 2022 Rotary Phone, How AI Imagines Zepplin, Are We Alone In The Universe 1 Comment Posted in Arduino Hacks, LED Hacks Tagged addressable led, ESP8266, light painting Post navigation This isn’t the first LED light stick we’ve seen, if you’re interested in such things. There aren’t currently too many galleries of DIY LED-enabled light paintings, but we’d love to see some custom modded light painting approaches in the future. Some future improvements planned for the project include TFT/OLED support, rainbow or color gradient patterns in the LEDs, and accelerometer or gyroscope support for supporting animation. Images are drawn from the bottom row to the top, so images have to be transformed before updating to the LED painter.

The project uses the Adafruit NeoPixel, ArduinoJson, and Bodmer’s TFT_HX8357 libraries for implementing the BMP drawing code, which also allows for an image preview prior to uploading the code to the microcontroller. The settings for the number of LEDs, time for the image row, and STA/AP-mode for wireless connections are also set by the web interface. Images are stored internally in Flash memory and are uploaded through a web interface. It directly supports 24-bit BMP, with no conversion needed. The LED Lightpainter takes the Pixelstick a few notches lower for amateur photographers and hobbyists. Nevertheless, it’s a huge step up from waving around a flashlight with your friends.

The equipment needed for setting up the light painting sticks runs in the order of hundreds, not to mention the professional camera and lenses needed. It’s actually based on the Pixelstick, a tool used by professional photographers for setting up animations and photorealism shots. This weekend project from uses an ESP8266-based microcontroller and an addressable WS2812-based LED strip to paint words or custom images in thin air. Light painting has long graced the portfolios of long-exposure photographers, but high resolution isn’t usually possible when you’re light painting with human subjects.
