Hacking an analog clock to sync with NTP - Part 2

Since I am more familiar with C/C++, it makes sense for me to use the Arduino IDE (rather than Lua, the other alternative).

Everything was surprisingly easy to setup. I first installed the Arduino IDE, Then I followed the instructions here to setup the board manager within the IDE. I really wanted to base the WiFi configuration part of the project on WiFi Manager, so I added that to the IDE using the library manager.


I also setup the board type under "Tools". There is no entry for ESP-12F, so I went with the ESP-12E since the two should be virtually identical as mentioned previously.

With all the setup done, I went with the simplest possible WiFi Manager sample code, which looks like this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
#include <DNSServer.h>
#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h>

void setup() {
  WiFiManager wifiManager;
  wifiManager.autoConnect("ESPCLOCK");
}

void loop() {
}

Then I click on "Sketch, Upload" and let the magic happen...


Lo and behold, a new WiFi network appears!


Connecting to it automagically brings me to the front page of the captive portal.


To be continued...

Update: Line adapter for Ozito Blade Trimmer

Update (Dec 2021): If you access to a 3D printer, I would now recommend this solution , which makes it super easy to replace the trimmer line. I have been using it for a few months now with zero issue.

3D Printer Filament Joiner

I have been looking at various ways of joining 3D printing filaments. One method involves running one end of a filament through a short PTFE tubing, melting it with a lighter or candle, retracting it back into the tubing and immediately plunging the filament to be fused into the tubing: One problem with this method is that you can't really control the temperature at which you melt the filament, so you frequently end up with a brittle joint that breaks upon the slightest bend. Aliexpress even sells a contraption that works along the same line. As it uses a lighter or candle as well, it suffers from the same weakness. I am not even sure why you need a special contraption when a short PTFE tubing will work just as well. Another method involves using shrink tubing/aluminium foil, and a heat gun: But a heat gun is rather expensive, so I wanted to explore other alternatives. The candle + PTFE tubing method actually works quite well when you happen to melt it at the rig
