This instructable shows the principles involved in making devices to control home automation over the internet. We’re going to construct a device (or several of them), that talk to each other over the internet to control lights, motors for curtains/blinds, power sockets etc. In contrast to devices controlled from a web browser or phone, these […]

I love to integrate devices which are not supposed to be integrated and this guide shows you how you can control an Android mobile using Apple’s Remote. (Who said Apple devices work only with Apple products 😉 ) Also this is my entry to the Sparkfun microcontroller context. If you like this guide, please do […]

Drone racing is nifty as heck, and a need all races share is a way to track lap times. One way to do it is to use transponders attached to each racer, and use a receiver unit of some kind to clock them as they pass by. People have rolled their own transponder designs with […]

Adding an LCD display to Arduino projects can add real value but the cost of doing so can be significant. Not a financial cost – you can pick up 16 (characters) x 2 (rows) LCD for as little as £3.50. The cost is the pin count it can take to drive them. Using the built-in […]

This is my homemade Dual H-Bridge using the IC L298N. For control DC motors or step Motors ao other purposes just like you need. Breakout L298N.ppt1 MB Step 1: Hardware and Materials COMPONENTS: 1 x perf  board 13×26 holes (3,5 x 7,0 cm) 2 x AK300/3 connector 1 x 8 Header female connector for Arduino […]

This flasher/beacon circuit can be employed as a distress signal on highways, a direction pointer for parking lots, hospitals, and hotels, etc. The circuit uses a power LED, and provides more light than a typical incandescent lamp flasher. Use of a 6V or 12V SLA lantern battery makes the circuit portable. The heart of the […]

We analog designers take great pains to make our amplifiers stable when we design them, but there are many situations that cause them to oscillate in the real world.  Various types of loads can make them sing.  Improperly designed feedback networks can cause instability.  Insufficient supply bypassing can offend.  Finally, inputs and outputs can oscillate […]

Yes, I know this has been done before, but I wanted to build my own, using as few parts as possible.  I built this as a table top or wall mount model, but it can be scaled up to make a coffee table.  I built it as a study for a more ambitious project, which […]

https://github.com/stirobot/arduinoModularTFTgaugesI built a custom OBD II (on board diagnostics version 2 http://en.wikipedia.org/wiki/On-board_diagnostics) gauge in the clock of my Subaru BRZ (GT86, FRS) and a lot of people wanted me to build them one. Here is how you can build one of your own. My wife is about to give birth to our second son and […]
