For #GeekWeek, I Assembled A RasPi.

Hello, it's really been a while here. Sorry, I have been doing more of travelling around my country, Ghana and hardly gets internet on the go. Well I use no smart phone, I gave up on my Samsung GT-1900 some months ago for a Vodafone branded ZTE phone, vodafone 236FM. :( I hope someone pulls a surprise on my birthday with a Samsung Galaxy SIV. ;)
my current phone - vodafone 236FM
 Well, let's come to the reason for this post. It's #GeekWeek! Yes, YouTube Geek Week! I never knew until my pal from Sygil Media, +Paa Kweku Woode did and uploaded a video of me assembling my RasPi on Instagram. He caught me unaware. I did not notice him record. I was busy fixing my buddy, my newly found love. :)

Here you are, enjoy the watch

I Have A RaspberryPi!

I have been silent here for a while, sorry, school wasn't fun anymore; exams, project presentations and documentation et al. Thanks be to the Creator, all is over. My final semester has really taught me lessons and challenged me to do things I once dreamed of. Yes, I have awesome dreams. :)

I once told my friends I wanted to study electronics and build robots (I have always wanted to build a robot), they badly pulled my legs. That did not stopped me, I kept a lot of dreams to myself and shared not with them. I knew someday these dreams will be materialised. At Barcamp Takoradi 2010, I met the TTI Fab Lab and lo and behold, the journey for the search of knowledge on electronics begun.

My last days in school, CapeVars was magical. I cried sometimes. I had a tall list of projects and did not  know which to do and where to start. I discussed these with lecturers and friends and finally settled on an arduino-based temperature monitoring system with SMS capabilities (using Falcom Samba75 GSM modem). I went in for this because of the arduino! I wanted to know what/how it is and works. And whiles I worked on my project, I did tried out other basic stuffs.

On submission of my final year project, I was promised a Raspberry Pi in return of the  arduino kits I used. I got excited, but never knew what followed. I had to present a real project idea, make sketches and prove what it  is, uses and what I hope to learn from it. I failed on the first presentation, I was not well convincing. I could not just say the type of processor the RasPi uses, upon all the weekend reading and study. I guess I had to much on my mind.

Yesterday, I got up fully prepared with less #vim to get the RasPi. I missed the set time and had to wait for 6:00pm to show up. At 6:30pm, "So what do you intend to do with it, what do you have?" the first question went. A sudden dumbness struck me, I managed to say a few things about the board and the projects. In a blink of an eye, I saw a blue box with the inscription "MAKE: kits for the maker in all of us", a Raspberry Pi Starter Kit from makershed?  There I remembered something he said on the first bid, "I got no one to give it to, you have to prove a reality in your concepts". "Hope you know the worth of this? It is expensive, it's not just the board, it contains many things to get you started, here you are, all the best." Silence griped me as I stretched out my hands for the box. "You have to update me on whatever you do with it. In two (2) months time, I expect a report. All the best in Kenya!, Good bye."

I just did not believed what had happened till I got home. The MAKE: Raspberry Pi Starter Kit costs around US$125.00. The box had everything without an SD card and one of the locks for the MAKE: Pi Enclosure was missing. I had decided to do something over the night, all plans had to come to a halt  cos I had no SD card. I am going for one today and start the hacking and tinkering.

I just do not know what to do, all I say is thank you, Dr. Farahmand, you are a real gem. I am not going to rest on my oasis, I will do my best to get the best out of this gift.

[Weekend Hack] Arduino + ADXL3xx Accelerometer

Do you remember I once told you I have an arduino uno board? I don't have enough accessories; a LED, a push button, 10 jumper wires, a  breadboard and an ADXL3xx accelerometer chip. Last weekend, I tried out the LED and the push button. 
This weekend, I set out to explore how best I can use my accelerometer chip. Though I could not understand most of the resources found, I resorted to this tutorial on the arduino site.  I wired up the chip and LED nicely to the breadboard and powered it with  5V. All I knew was, I will be receiving values from 0 to 1023 (0 at 0V and 1023 at 5V). I set my LED up to blink when the value of the x-axis exceeds 512.

board setup

I turned the board around, placed my phone underneath and introduced vibration to it. Luckily for me, it worked, seeing different values pop up. See my codes below:

Building Chrome Themes


I love themes, they beautify your browser. Since 2011, I have been designing cool chrome themes for myself and the world showcasing the rich culture and acts of the people around me. I have 13 themes on Chrome Web store to my credit. I hope to double it up by the end of the year with inspiring and charming African themes.

Though there are simple available tools to making chrome themes, understanding and writing your own from scratch is where the fun is. You make it how you want it. You get to know your browser and appreciate it.

Twine - inspired by @mutombodapoet

I wrote this pdf (revised) about two(2) years ago, and though the browser has seen updates, it has all the resources one needs to create a theme. It requires only a single json file to get a theme built.

Download, read and have a hands-on. Don't forget to send in your comments and reviews. Get in touch on twitter.

Finally Here!

Huh! I am finally here for good. I will not delete this blog, the third time I am creating a blog here :( Not my fault, tumblr caught me in her net. I love tumblr so much. It is simple and easy to use. I easily and quickly publish my stuffs and get other interesting posts reblogged. It's pretty much like twitter. You post, favorite/like and reblog. I am so attached to it.

Now, I am here for just two reasons; to frequently create and share content on my g+ page and to enjoy analytics. I want to reach the world through this blog; share thoughts on technology and social issues, give to the community what I have learnt and also to share the humors in my life.  With the stats tools here, I can easily know who my audiences are and where they are from. It will help me to be strategic in reaching out wide.

Welcome to Bigs' World, fasten your belts and hold on for a jolly ride from a -to- z of my raves and rants. Hey, beware of the ride! Follow me on twitter, @kobebigs and visit me on for some of my posts. It's past 4:00am, I got to take a nap.
See ya!
