A can of compressed air is pretty amazing to have around whether you're working on electronics or even automotive maintenance. Unfortunately, they can cost as much as RM50 or more per can as they are mostly imported.
The idea of salvaging an electric motor from a washing machine for DIY (do-it-yourself) projects isn't new as it's a relatively high-torque motor and as pointed out in this YouTube video, fairly cheap and easily sourced. It's not just limited to a bench grinder, you could even make a belt sander with the right wheels and pulleys. The possibilities are endless.
