EBike Battery Pack || DIY or Buy || Electric Bike Conversion (Part 2)

in the last episode of this video series I showed you how to create your own sensored ESC in order to power an electric bike wheel with low voltages but since the achieved rotation speed was too slow and not many people want to create their own ESC for an E-bike conversion let’s rather switch […]

What’s in my (PPE) bag? Heavy Duty Marine Mechanic’s Personal Protective Equipment

Today on Repairs101 I’m going to show you what’s inside my Personal Protective Equipment bag. OK you can see I did a much better job of keeping this one clean than I did with my tool-bag. It’s because I don’t carry it everywhere I just keep it under whatever bench I’m working on. So the […]

Sources of Heat and Protection of Weld pool

So, we have seen that for developing the weld joints, we can use the different processes in which heat can be used or even without application of the heat just by using the pressure joints can be developed. But for the fusion welding process heat is invariably applied for melting the faying surfaces, and thereafter […]

How to Make a Battery Protection Circuit (over-discharge protection)

Powering homemade projects with rechargeable batteries is actually more difficult than it sounds. This is because most battery types cannot be over-discharged, as doing so may damage the battery and make it unstable. Consumer electronics overcome this issue by using clever battery protection circuitry that constantly monitors the battery’s voltage, automatically switching the device off […]

How to Make a Shunt Current Sense Resistor

Hi, I want to make a *beep* I said shunt! I want to make a *shunt* current sense resistor. Basically the way we measure current is by converting it into voltage passing it through a known resistor which we call a shunt and so the current is the measured voltage divided by the known resistance. […]
