The document describes a tech intern position at CoolJunk, a DIY kits maker company based in Delhi, India. The internship involves hands-on work developing new hardware platforms, interfacing sensors and wireless modules with microcontrollers, and coding. Requirements include a technical background in electronics engineering and demonstrated skills like circuit design and programming microcontrollers. The 6-8 week internship offers a stipend, industry exposure, and potential for extension. Applicants must submit solutions to programming and electronics problems to be considered.

1. Tech-Intern at CoolJunk
A place where we focus laser-sharp and work towards
doing only one thing:
Creating great kits which learners worldwide can use to
build things and inspire themselves to learn more.
That’s it.
**All jobs demand creativity, zeal and passion**
You are studying or have studied Electronics Engineering. You want to make a career in R & D
and love sweating on hardware, living on coding and aspire to build cool stuff.

2. Requirements:
You are an undergraduate/graduate B.Tech or M.Tech. in Electronics Engineering.
1. You believe that you have done a lot of hands-on technical stuff during your job and college.
2. You are the kind of person who can be thrown into unknown technical territory, can learn
stuff at the speed of thought and then come up with totally real, original and creative ideas
and eventually, execute them.
3. You should be able to make us nervous with your technical skills and knowledge (not with
grades/percentages/college degrees/courses/college festivals/workshops).
Do not apply, if you feel, you know something or have some vague idea about the
subject, you have built some beginner projects like basic line follower or remote
controlled car during your college.
We need people with real technical skills, not bozos. We will test you practically
on hardware.
You need to show us the projects that you feel proud about.
Skills:
C, AVR, Arduino, Communication Protocols(UART,
SPI, I2C), Strong Fundamentals of Electronics,
Circuit Designing, Eagle + Creativity

3. Profile:
You are going to work on 8-bit µCs to develop new, exciting projects. You will be responsible
for:
1. Development of a new hardware platform.
2. Interfacing of different analog and digital sensors with the µC such as proximity sensors,
accelerometer, gyroscope, force, etc.
3. Interfacing of wireless modules such as zig-bee, bluetooth, GSM/GPRS, Wi-fi.
What do you gain:
1. Rs. 15,000 per month is the stipend.
2. Religious Booze, Treats, Movies and Hangouts.
3. Start-up Exposure
4. Opportunity to work with young and dynamic people.
5. Attitude. We don’t brag about our quality of work.
We simply do. If someone comes to us and says, ‘I
have done this awesome work’. Our answer is
‘congrats’.
6. If we like you, your internship might be extended into
part time association/summer internship.
7. You may ask for a certificate.

4. Problem Sets:
1) What are your thoughts on the way programming is taught at the school level and how
'introduction' to programming is handled at the college level?. How would you go about
teaching programming to 14 year olds? What platform/s would you use? What programming
language would you recommend the person starts with?
2) What is open drain? Where and why is it employed? Give examples of 2 protocols which use
open drain as the physical implementation. Use Eagle Layout editor (or any other schematic
entry tool) to schematically show the physical implementation.
3) There is robot which contains a micro-controller board and a few sensors for line following.
The micro-controller board also has 2 switches, an LCD and a serial port.
Now, if someone presses the first switch, the following processes will take place simultaneously:
calibration of the sensors and the LCD showing the sensors output.
As the second switch is pressed, the robot starts following the line and simultaneously, LCD
shows the following status: SWITCH 2 PRESSED + ROBOT IS FOLLOWING LINE.
Now, if at serial port, the controller receives some data then it has to dump that data to
program memory, while LCD will show the Code is Burning.
Write your approach to solve this problem and the code as well. You can choose any 8 bit
controller. Also explain why you choose the specific controller for this task.
Deadlines:
1. All entries should be submitted by 15th November, 2012 (12 am, IST).
2. Final round: 22nd November, 2012.
Duration:
6-8 weeks from December 2012 to January 2013 (depending upon your college schedule)
Plus
2-3 months in Summers of 2013
Plus
Part-time Association
Location of work:
Delhi office, District Center, Janakpuri.
