Shorting the terminals of the motor will result in a braking action, but not as good as a mechanical brake.If you are using a H bridge to drive the motors, you could short the two terminals of motor by driving both terminals positive or negative at the sema time.
The finished power supply looks crips and professional :) Thanks for sharing.The schematics shows a negative voltage rail which is derived from the input AC voltage (D5, D6, C3,R3 and D7) This is why it requires AC input to work.
A very clean and neat method to make boxes.Board cutout pattern in the MDF sheet could be optimised to reduce wastage and minimise the cut length.
Love this design. Good use for an old door.Thanks for sharing!

This is a really good ible. Could you provide a link to the online shop where you ordered them? It would also be good if you could provide suggestions on what to look for when ordering earthworms online. Thanks.
Also leave another window open such that the air that gets in has an opening to get out, preferrably at the far end of the room such that the fresh air traverses teh entire room before exiting. This is forced cross ventillation.
The idea is really good. Almost always, the water tank (the bottom sump) is a separate moulded plastic attached with 2-4 screws to the top plastic part containing the fan and cooling pad assembly. While mounting the cooler to the window, care should be taken to ensure that the weight of the lower sump should not be left supported by the top part alone. A base support should always be provided. Luckily in your design, the window grill is recessed allowing the cooler to rest on its base on the protruded grill. I wanted to do this for quite some time, but I dont have any existing base support and did not want to build one out of plywood/metal.
