How about making your own smarphone? Making a cell phone or smart phone is not out of reach for clever hardware hacker. If you are planning to make a simple cell phone, ArduinoPhone project shows how you can build one. Or you can check the platforms used to build the cheapest cell phones. Are you looking →
I was some day wondering how to connect IO to Android smartphone or tablet. One well known option is to use IOIO or IOIO-OTG board connected to Android device USB port. The IOIO (pronounced “yo-yo”) is a board specially designed to work with Android devices and robust connectivity to an Android device via a USB →
I have bout a lot of stuff from Dealextreme web shop that I mentioned some years ago at my blog posting. I can still recommend that place like I did years ago. Now I have found another interesting looking place which have similar products sometimes even cheaper prices. Bang Good at http://www.banggood.com/ has a lot →
Did you know today is Arduino day? Neither did I know that 29th March is Arduino Day, but I learned that when Hackaday write about it. →
Few days ago I wrote about SCADA for Arduino that allowed to build a nice computer user interface for controlling Arduino. This post is a continuation to that. In the earlier posting I got the LED on Arduino board to be controlled on/foo with SCADA software. Now I connected a relay module to this output →
Acimut Monitoriza for ARDUINO is an interesting project that combines that combines free Scada software with Arduino hardware platform. Acimut Scada Monitoriza is a SCADA application that lets you control any process. It is designed for control and monitoring of production plants, and costs some money. Acimut Monitoriza for ARDUINO project offers Scada Monitoriza software →
I have written about Arduino boards a lot, but there are also other small interesting quite similar development board recommended for me to check out. The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port and →
I needed to do some AC current measuring with Arduino, more accurately than with special AC current sensor I tested earlier. To do that measuring I bought Meeeno ACS712 Current Measuring Sensor Brick Module Board for Arduino. This is a picture of that module from dx.com: This module is pretty easy and safe way →
What do you do when your micro-controller project runs out of horsepower? Well you increase the power in a way or another, like increasing clock speed (maybe up to over-clocking) or change to a faster processor family. What to do when your Arduino Uno isn’t fast enough? The UNO Overdrive article shows The Uno/Dumilanove Overdrive, →
Did you know that your optical mouse contains a very tiny, very low resolution camera? Your Mouse Is A Terrible Webcam article tells how to turn that tiny optical sensor into a webcam. Logitech RX 250 has an ADNS-5020 optical sensor (15×15 pixel grayscale image sensor) with SPI interface. The project uses Arduino, Ethernet shield, →
