3D printed lantern for my wife
Summer work for my wife, a little lantern with led and removable battery
New Ciclop board in progress
I’d like to share some pics of my current work. New board for my Ciclop 3D scanner, in the next week I’d like to share the tutorial on how to build It.
ATtiny Programmer Board (ArduinoUNO As ISP)
I really like the ATtiny and programming it, so I built a simple board to use Arduino UNO as ISP in a faster way.
PCF8575 i2c 16 bit digital I/O expander
Library to use i2c pcf8575 IC with arduino and esp8266.
This IC can control (until 16) digital devices like button or led with 2 only pins.
Can read and write digital value with only 2 wire (perfect for ESP-01).
I try to simplify the use of this IC, with a minimal set of operation.
Temperature humidity sensors comparison (Data) Part 3
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer (competitor bmp280, DHT11, DHT22, Dallas and thermistor).
Finally the comparison.
Temperature humidity sensors comparison (Code configuration) Part 2
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer (competitor bmp280, DHT11, DHT22, Dallas and thermistor).
Today the code to get sensors fully working.
3D Printed base for Ciclop 3D Scanner
I’m going to create the famous Ciclop 3D Scanner, but my first problem is how to get round plexiglass base, but the costs is too expensive. So I decided to design a printable one.
Temperature humidity sensors comparison (Specifications) Part 1
Wherever I go, peoples asked me why I chose DHT12, and why I spent time to write a library for this small sensor, in this articles I’ll try to give an answer, and introduce the competitor bmp280, DHT11, DHT22, Dallas and thermistor.
Today the specification of the sensors I use.
Voltage divider: calculator and application
Voltage divider It’s a circuit very common in electronic, I add a simple calculator and some application in this article.
