FIXING PLASTIC TUB OF FRONT LOAD WASHING MACHINE
Hey Junkers,
Ever wanted to fix a washing machine plastic tub on your own ? Fixing a washing machine tub can demand a lot of hardwork and you will hae to get your hands dirty. In my washing machine's scenario, three bolts are supposed to withstand the counter weight attached to the tub. In our case one bolt was missing and started domino damage. Eventually the washing machine had reached a non-functional state. The plastic tub had broken. To fix the plastic piece we used following glues (you can try others) :

Eventually the washing machine had reached a non-functional state. The plastic tub had broken. To fix the plastic piece we used following glues (you can try others) :
- Araldite (resin and epoxy glue from Pidilite)
- m-seal (resin and epoxy glue from Pidilite)
First layer of m-seal |
Holes drilled for wire bonding. |
Wire passed through holes. |
Almost in place |

TRANSFORMER LESS POWER SUPPLY
You can build a robust, small and cheap transformer-less power supply 230 V AC to 5 V DC or 12 V DC practically up to 10 mA using a capacitor resistor zener diodes and normal diodes. The only problem with this kind of power supply is that its not isolated. You will get electric shock if you touch any connections from 5 V side. Refer this document to design yours. Microchip transformer less power supply application note.
TRIAC SWITCH USING A OPTOCOUPLER
The following demo video shows switching ON or OFF a bulb using triac. If you connect this module to a bluetooth module GPIO or a microcontroller GPIO you can control switching of any appliance. Phase switching to control fan speed or bulb intensity is also possible. The circuit uses a optocoupler, triac and few resistors. For circuit diagram refer to this link
