Neutrino-1

That's really interesting!! Gald you like it!

You should probably get the library within the Arduino library manager. Just make sure if the author is PaulStoffregen. The other way would be, download the git repository and install the library manually using Arduino IDE [Go to sketch -> include library -> add .zip library -> select the downloaded zip file (the timelib git repo) ].

(wireless_SD.ino file)Replace line 5 and 6 with your route SSID and password and replace from line 23WiFi.mode(WIFI_STA); WiFi.disconnect(); delay(100); WiFi.config(apIP, gateway, subnet); WiFi.begin(ssid, password);This would make the esp8266 work with your router.

Flash led is connected to GPIO-4, same as DATA-1 pin on the SD card. This won't be a problem when you use the SD card in SPI mode but in SDIO it uses DATA-1 along with other pins, maybe this is the reason for strobes.

That's really impressive!

Glad you liked it!

Thank you!

Thank you!

Sorry couldn't help your sooner, But you have done a great job! Hope your solution helps others who is facing similar issue.

I really love how flexible the 555 Timer IC can be! Thanks for this instructable!

Thanks that's really helpful!

it's just version 0.1V, working on upgrades!

Thank you!

The battery isn't that great, because of the existing LDO regulator, Probably I will update later with an efficient one and optimise the code.

Next time I will make sure the cat is completely visible! ;)

Glad you love the project and thanks for all the valuable feedback, if time permits I will defiently implement all of them!

Thanks for you feedback, it will keep me motivated!

They are pretty durable! It's slightly smaller than the PCB dimension 33mm X 46mm.

Good job!

Glad you liked it!

try getting the code from GitHub

You can build a bigger display from scratch, you can check out thisVideo : Rest of the circuit should remain same (just be aware of power management)

Glad you liked it!

Yes, Pro mini has the same connection as Arduino nano.

Nano was very easy to prototype that's the reason it was used in step-2.Later to decrease the size of the overall device I used the pro mini.

Thanks man! I will ping you.

Thank you! As far as I know it can support up to 32GB.
