ALISS

[Part 1] [Part 2] [Part 3] [Part 4] [Part 5 – ALISS] [Download] Just FYI, ALISS v0.7.4 has changed so dramatically that a lot of what follows is no longer representative of how the programme operates. The basic structure is the same, but almost all of the variables have changed, among other things. That said, I have not yet finished testing 0.7.4, so this article will remain here as long as 0.7.3 is still available. I am also...

Arduino Irrigation System #4

[Part 1] [Part 2] [Part 3] [Part 4] [Part 5 – ALISS] [Download] The Solar System Billions and billions of stars. . . oh, sorry, I was having a Brian Cox moment. As I mentioned in Part 1 the nursery is not connected to the Grid, so to power the irrigation system, we need to get our Hippie on. Getting ‘our Hippie on’ is much easier said than done. You can’t just plonk down a Solar panel and a battery and expect...

Arduino Irrigation System #3

[Part 1] [Part 2] [Part 3] [Part 4] [Part 5 – ALISS] [Download] In Part 1 we worked out what it is we want to make, why it needs making and we ended up with a basic circuit. In Part 2 we learned about Solenoid valves and delved into the Arduino code that will make it work. Now in Part 3 we will look, briefly at the circuit board. Below is an image of the topside of the finished circuit board. In the middle you will see an...

Arduino Irrigation System #2

[Part 1] [Part 2] [Part 3] [Part 4] [Part 5 – ALISS] [Download] We left off in part 1 with a simple circuit straight out of the Arduino Projects Book that allowed us to manually control a DC Motor. We need to adjust the circuit slightly because we don’t want to have to manually turn on each solenoid valve and then manually turn them all off again; if we did that we might as well have not bothered. (Also, we don’t...

Arduino Irrigation System #1

[Part 1] [Part 2] [Part 3] [Part 4] [Part 5 – ALISS] [Download] As with everything, I like to jump in head first and work it out from there. That’s exactly what I did with my Arduino Irrigation System, only it took quite a long time to accomplish the ‘working it out from there’ bit (about 6 months I’d say), but I did it, and here it is in all its glory. What do you mean you can’t see it!? This is a...

Control TV via IR with Arduino & AppleScript Part 3

[Part 1 Learn your IR codes] [Part 2 Control Arduino using AppleScript] [Part 3 Examples and Downloads] UPDATE: Works with OS X Yosemite.   Part 3 In Part 2 we learned how to control our Arduino using AppleScript, or more specifically, how to send Shell commands via AppleScript. In this next section we will look at a practical example, one which will take a User’s input and translate that into the appropriate IR commands...

Control TV via IR with Arduino & AppleScript Part 2

[Part 1 Learn your IR codes] [Part 2 Control Arduino using AppleScript] [Part 3 Examples and Downloads] Part 2 This next part, for me at least, came with a bit of luck. I found a forum somewhere (which for the life of me I can’t re-find) which pointed out a very important part of the IR code which the IRrecord sketch we used last time didn’t show. As we know, the serial output of the IRrecord sketch showed us something...

Control TV via IR with Arduino & AppleScript Part 1

[Part 1 Learn your IR codes] [Part 2 Control Arduino using AppleScript] [Part 3 Examples and Downloads] Part 1 What with my exams finished, I thought I’d take some down time and build an IR Remote that I can control with my computer. I use a 22” LG TV as a display for my MacBook, but because it’s a TV and not a monitor, it doesn’t switch off when I put my computer to sleep. Pressing the on/off button on the front of the TV doesn’t...

Outdoor Motion Activated LED Light

Outdoor Motion Activated LED Light

Following on from my recent wearable project, I was asked to build an outdoor motion activated LED light for the front door. I had briefly read about PIR sensors a few weeks ago, and I was keen to give it a go. Originally I was going to use some, or perhaps all, of my left over NeoPixel strip, as it has a weatherproof sheath, but I decided that it just wasn’t quite right for the project. Instead I settled on an Adafruit 16 LED...

The Story of the Torch

The Story of the Torch

Back in 2008, I owned a brilliant torch. It was a blue anodised aluminium torch with 19 bright white LEDs set in its face. It was a brilliant torch. I kept it in the car because that is one of the places where a torch is most useful, well, at least for me. But in 2008 it was stolen when my car was broken into – no doubt they used it to break into other people’s cars. It was the only thing that was stolen, but despite the damage...
