Line follower Robot - without using Microcontroller!!

Image
Difficulty Rating : 3/10 Ever wanted to make a Line follower Robot, 'without' using  Microcontroller ??? Then you have visited a right place. Inspiration: I stumbled upon this Robot in my First year of Engineering during one of the Intercollegiate Robotics Championship (Regional) and ever since, it was my dream to make this Robot on my own. I googled for it & got many designs, but all Microcontroller based. I even shortlisted a few but my senior Pratik Kamat asked me take small steps first and suggested me to make one without the use of Microcontroller and with self designed logic. Now, as a part of Electronics workshop in Sem-IV (II Year), we were supposed to make a project based on 'Electronics'. Since I was introduced to Microcontrollers at that stage, I made a proposal to make a Microcontroller based LFR( Line follower Robot). But it was rejected by my Batch in-charge as no microcontroller based projects were allowed for current semester. So i decided...

12V 7.2Ah SMF Battery Charger: Smart Approach for Smart devices by Smart People !!

Image
Difficulty Rating: 5/10 Abstract: This project gives an overview of the Sealed Maintenance-Free (SMF) Lead-Acid Rechargeable Battery charger using 3-pin  IC LM-317 as voltage regulator and opamp IC LM-324. In case of a simple battery charger, when the battery is fully charged and is left plugged in for more than a day or two, the battery may get damaged. In order to protect the battery from this major risk, the proposed battery charger is designed in such a way that the charging current falls gradually as the charging progresses. So the battery can be left plugged into this charger indefinitely, and it won't bother it in the slightest. Designing the Circuit:   Click the image to view the enlarged version The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5A over an output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistors, R 2 ’ and R 2 ”  (R 2 ...

NiMh 12V,1.2Ahr Battery Charger

Image
Difficulty Rating: 4/10 Exactly 5 months after my Internship/project  at M.A.P.L. Pune, on Lead acid SMF Battery charger,  my knowledge on Battery charging was put to test by a Mechanical Engineering friend. I was asked to charge a 12V 1200mAh NiMh battery. Now, before getting into its technical aspects, a little overview about battery chargers. General battery charging techniques- Trickle chargers This charger provides a constant charge rate of ~ 0.1C. The general idea behind keeping the charge rate low is to compensate for the batteries self-discharge. The charge rate being low, the battery can be left unplugged for days!!!The charge rate of the battery should be equal to self-discharge of the battery. Such chargers are generally used in industrial applications , where less of human intervention is required. Float chargers The battery and the load are constantly connected to the source. The float chargers maintains full charge & provides a protection against...
