Introduction For many of us, we started out programming on desktops and servers, which seemed to have infinite memory and processing power (well, depending on when you started programming, I guess). There was little reason to optimize your code since...
High speed photography is fun. Ultra high frame rate video, even more so. But since not many of us have access to $10,000 HFR cameras… we have to make do with long exposure shots a perfectly timed camera flash. You can design a system to trigger the flash at just the right millisecond — but they’re still pretty expensive typically.
Hi!In this Instructable I will tell you how to make a good looking smartphone alarm clock. The alarm clock displays the time, can charge the phone and houses a mini amplifier and speaker. I had the idea to build this alarm clock for a long time but the "Time" contest helped me to get started. The design is inspired by the Areaware alarm clock. I loved the design and simplicity from the first moment I saw it. The disadvantage was that the costs where a little bit high for only a piece o
Let’s equip Arduino with a serial-interface JPEG Camera with IR and try two applications: the first one saves shots (on a SD-card) at regular intervals while the second uses a PIR sensor to detect intrusions and photograph what happens. Recently, miniaturized cameras with serial communication interface have been launched on the market. Compared to traditional cameras, they offer easier integration with Arduino or other microcontroller-based boards. It is quite easy to understand that using
Hi,in this instuctable you will learn how to make world clock weather bot using Arduino Mega and ESP8266 (AT mode).Features:• personalized bot with LCD screen as mouth, potentiometer as nose and green LEDs as eyes• choosing wanted city/country by using serial communication• saving wanted city/country into EEPROM memory• getting geolocation data, weather data and country code using OpenWeatherMap API and ESP8266• getting local time using TimezoneDB API and ESP8266• p
Hi! Kaeru no Ojisan is back with Car No.06. Car No.06 is a Programmed Automatic Driving Car with following procedure; – Simulate the Car Trajectory based on the Target Passing Points. – Drive automatically as simulated using Reflective Photosensor and Gyro Sensor . – Adjust Car Position to the starting point using Web Camera, after […]
FabScan is an open-source, do-it-yourself 3D laser scanner.It started out as a Bachelor's thesis by Francis Engelmann, supervised by René Bohne. You can find official project here.I made my own box from MDF hood sheets and use different hardware parts.I decided to make this guide to show to you my work.All credits for Arduino software and computer application goes to FabScan team, so thank you very much for this great open source 3D laser scanner!Dev: Francis Engelmann Official page: hci.rwth-aa
Of all the things we do at Raspberry Pi, driving down the cost of computer hardware remains one of the most important. Even in the developed world, a programmable computer is a luxury item for a lot of people, and every extra dollar that we ask someone to spend decreases the chance that they’ll choose …
Micro-servos are great devices perfect for adding motion to your projects. Unlike steppers, they can be controlled directly from your Arduino or other favorite microcontroller. Most servos are limited to 180 degrees of motion. This allows microcontrollers to know the exact position of the servo's shaft. You can find continuous rotation servos, but if you have access to lots of cheap micro-servos of the 180 degree variety, it might be helpful to learn this quick hack to make them continuous. What
The RGB clock utilizes the RGB color composition model used in all color displays. This model uses three ‘basic’ colors, namely red, green and blue, to build any other ‘composite’ color of the spectrum. With RGB clock, however, only ‘pure’ basic colors are combined, thus limiting the resulting number of colors to 8: red, green, blue, yellow, cyan, magenta, white and ‘black’. This way it is always possible to see which of the basic colors are curren
