This is first version of my low cost 3d printed robot arm. It is based on Ikea Tertial lamp. I choose it because it has very good kinematic with using springs to unload servos. So you can use different number of springs to achive diffrent lifting power. Techinacal specification: 5 DOF. Full lenght: 690mm Lifting […]

Preface My daughter asked me to build her a treasure chest that she could use to store her most valuable things. Obviously she demanded it to have some kind of a locking mechanism so only she could open the box. First thought was to use a keypad but then her grandfather bought her a diary

Story We love our workshop, but it has one downside (or maybe upside) – a large flight of stairs to the gallery. We constantly need to move parts and components between one floor and the other, so we’ve been plotting different ideas: drones, dogs, carrier pigeons and what not, and then it hit us! A

Story Have you ever wanted to make your own interface that can display the time, date, along with the temperature and the humidity? Well it’s a lot easier than you’d think. A few important components are needed, as shown below. Arduino Uno/Nano Firstly we will be needing a micro controller. I used an Arduino Uno

Introduction The Serial Basic is an easy to use USB to Serial adapter based on the CH340G IC from WCH. It works with 5V and 3.3V systems and should auto install on most operating systems without the need for additional drivers. It’s a great lower cost option to the extremely popular FTDI Basic. The Serial

Introduction: Drinking enough water is very important for our health. Drinking more water can lead to clearer skin, better overall health, improved productivity and brain function, increased energy levels, and even weight loss. In our busy lives, it is really hard to remember to drink enough water. And most of the time we forget to

I have done several designs of digital clocks for Arduino using LEDs and LCD displays, but this one is more special because I added other features like alarm and motion sensor (PIR). Main features PIR (Presence Infrared Sensor) RTC (real-time clock) Alarm Temperature Humidity Water dew point Encoder to set the time and alarm Permanent

The Project This project is a combination of the many smart fridges and pantry’s of the past. The idea is to combine all of them while also introducing Amazon’s DRS system through Alexa and the Echo products as a bonus feature. The process will be simple: As you put the item you purchased via Amazon
Amazon Kitchen DRS Continue Reading
Story After designing the “Clock Set Date Time” and hearing the suggestion of ArduPic , I thought it would be a good idea and also useful, add a “wake-up alarm.” A small change to the code and adding a few components: Here’s “the Alarm Clock“. Compared to the previous project, I added a buzzer Piezzo,
