LED Doofer

Dad an I made a doofer that has ten red LEDS. They flash one by one, they start from right to left. They speed along as fast as lighting.
It took heaps of soldering, I did most of it but Dad made some mistakes so he did the rest. He also burnt his own fingers. I am going to bring it to my cousin's house when I go this holiday.

[The design for this came from here. The mistakes in the implementation were entirely mine. That Emma was soldering with her left hand was also my fault. Things got better after she switched back to her right. The burn was inconsequential - I only said Ow! Dad.]

Calla

Calla is our cat,
She is like a mat.
She sit's in a sunny spot,
Right next to the flower pot.
She gives me a glare,
If I sit on her chair.

Blinky Bug and Traffic lights

I made a Blinky Bug with Dad. It is a silver spider with red LED eyes. When you tap the antennae the Blinky Bug blinks.
We made it with a battery, two LEDs, some guitar strings, pipe cleaners and fuzzy balls for the body. We taped the battery, the LEDs and the guitar strings together and glued on the body and legs.



We also made traffic lights. It took a lot of planning and rebuilding. In the end we brought a rotary switch because it turns on one light at a time. We used specific colors for the wires that match the LEDs. A lot of soldering was involved and I burnt Dads finger with soldering iron. Dad drilled holds in a box for my traffic lights and rotary switch.
