ARDUINO- SERIAL ECHO CODE
Jul 3rd
The code contains a simple Serial Protocol that can form a basic-robust backbone of a Computer-uController Communication. It works with the principle of TCP/IP. Where the computer sends info to the uController, if the information string was properly received, the uController responds back with either $Y(for success) or $N(for failure)

I got this video from my fellow friend’s webpage (www.ubcecc.com/blog). It’s a good video 
MICROCONTROLLER PROGRAMMING TUTORIAL
Jun 24th
I have just added a small Microntroller Programming tutorial using PIC16F877A.
This tutorial should work for most other PIC microcontrollers.
The tutorial can be found here LINK
Have Fun with your Projects, remember to email me. I probably can help you out if you are stuck. When you email me with a problem, PLEASE provide a screenshot of where you are stuck. It’s hard for me to comprehend someone’s description, as multiple people have multiple description of the exact same thing.

Meanwell Power Supply Mod
May 20th
I recently got a shipment of three SP350-48 Meanwell supplies. From the endless sphere forum, I thought they were just CV(Constant Voltage) power supplies, and thus I was designing a CC(constant Current) circuit similar to what you can buy from the Tppacks website.
In the End I have seen that these are actually newer model, with 3-shunts, and most IMPORTANTLY, they are CC-CV (Constant Current-Constant Voltage).
The Max current delivery at 59V was seen to be at 9.8A for 5minutes, and then drops to 7.6A( which is 0.3A more than rated current).
What I wanted was somewhere around 3A for the charging rate. Thus, what I did, was simply cut off 2 of the 3 shunt wires, thus reducing the current by one-third( to 3.5A). Not bad for $40. If I ever want more current again, I will simply resolder the shunts

XTRACYCLE KIT IS HERE
May 18th
This is a MUST HAVE for any ebikers who want to carry another passenger to share their box of electric fun

Btw, the Xtracycle kit does change the feel of the cycle. Here are a list of the changes
1. The Cycle is atleast 1.5foot longer(they say 15 Inches, but it feels longer)
2. Previously, My weight distribution was like this 28Lbs Front- 42Lbs Rear (yes, my cycle does weigh 70lbs)
Now it is 47Lbs rear, and 43 Lbs front. Thats almost 50-50. Which is good, and kind of bad too. You don’t want to be loosing traction on the rear wheel while making a turn (since the cycle is longer, I won’t be making 90° turns at 50kmph. Maybe 45kmph 
The good thing is, now, I can easily slip my Crystalyte 5303 on dusty road, or with wet tires(after rain) on the hallways of my building.
During hard acceleration, while I am done with 80% of the turn, the wheel drifts 8-) , causing the cycle to vibrate a bit due to the knobby mtb tires, which is kind of cool 
Another good thing about the bike being long is, now the wheelbase is longer, making the bike more stable even if the rear/front wheel has no traction.
Bad: During 4-10kmph the motor vibration causes the frame to resonate and emit a loud growling noise. So if you want a complete silent ride, look elsewhere.
Good: The cycle now feels like a motorcycle, growling to show off that you have 4kW(5Hp ) of power. Btw there is absolutely no noise after 10kmph. And how long do we cycle at <10kmph anyways 
! I am usually doing 35kmph+ most of the time.
Bad: due to the cycle being longer, causing the point of rear wheel being further away from the suspension pivot, and due to the laws of physics, The rear suspension spring now faces greater force.
Good: Suspension Feels Softer, ride is atleast 3x better. Small movement of rear shock is enough to smoothen out the harsh bumps.
Good: You can carry a person.
Bad: Its a little to wobbly for my taste when a person moves .
Overall Rating So far : 4.5 Out of 5.
Electric Boat
May 15th
Some photo of the upcoming Electric Boat Conversion project.
It will house a Agni Motor 95 reinforced, OSMC (Open Source Motor Controller), and bunch of lipo batteries. Very simple Conversion, yet elegant. Below are the photos of the old boat getting its finish touch paints, new touch up stickers, and a new name “Whisper”
