U720 modem updating
Heat intensity was regulated by moving alligator clips along the wire.
Then I used it to bend two 45cm*70cm big polystyrene sheets into shapes pictured below.
I often use melting glue gun to mount different parts as it is done in this case: both LEDs and controller glued to the lid with a glue gun.You may refer to the previous image for resulting shapes. Take into account that it's impossible to bend relatively thick (mine is 3 mm) plastic to have sharp corners.So you should consider resulting slightly rounded corners when perform bending and maybe introduce some tolerances into design.At that time I was aware few neighbors of him are using 3G USB modems with Yagi antenna attached.After small research USB modem was bought to do the same.
