Story We (most of us) really like Arduino because it’s possible to make cheap clones, lots of libraries, examples, forum support and community out there. Outside Arduino world, I like Cypress PSoC for some of its cool features like Graphical IDE, APIs, great features and understandable documentation. I have bunch of PSoC® 4 CY8CKIT-049 4xxx […]

Story Warning: Digispark uses Attiny85 PIN#1 as I/O – remove RESET button functionality Notes FOR ADVANCED USERS ONLY  The Trinket 5V and the Digispark share the same hardware design, right down to the LED being on PB1. Personally, I prefer the Trinket hardware over the Digispark, but the Digispark has a totally different ecosystem and is […]

Story This is a small semaphore you can put on your desk. You can use it to tell whatever you want to the people around it. For example, because you need some concentration and you’d like your colleagues not to disturb you. Or to tell the status of the system you’re managing. Or say which […]

Hot Yet? Attiny85 Faucet Water Temperature Sensor Testing Real life testing in the kitchen sink! Note the tri-color LED. Blue is cold and fades into Green which then flips to increasing Red at 85F.   Notes This project is an Attiny85 Arduino circuit and uses the Coding Badly attiny core available here: https://code.google.com/p/arduino-tiny/source/list For the […]

Chachka is born! Chachka is an Adafruit Trinket CLONE built from the ATtiny85 microcontroller.  Because it is a current Adafruit product, it has a training guide and its own support forum and lots of sample code.  All of this means that like an Uno clone, the Chachka will be well supported with firmware and libraries and […]

Story I went for a shower one day, was getting late for office. Running tight on time, but I didn’t want to come out of hot shower in cold morning. Without any clock in my bathroom I was saying to myself “Lets enjoy the shower for few more minutes, I might be over estimating the […]

Background A few years ago, a co-worker turned me on to this TV program called “The IT Crowd”. The show revolves around a two-person IT team and their “Relationship Manager”, Jen, who inadvertently landed the job by including some basic PC skills on her resume. Moss and Roy resent her for getting the position both […]

Story Yosh ! At last, finished working on this project. I have been working on this project for a while, then got bored and left the remaining work ( mostly firmware ) for a couple of months, ah ! the longest project I ever did ! What’s all this about ? This project is about […]

Introduction I’ve been fascinated with joule thief circuits since I made my first one.  It’s amazing what all you can power from a single AA or AAA battery.  The only problem is you can’t do much beyond light up an LED because the current isn’t “always on”.  With a couple of extra components, you can […]
