I'm teaching the Electronics Merit badge for Troop 6 this summer. We will be building a kit from www.electronicsmb.com to meet the requirements. My son is part of the class and we did his kit as a practice run... He'd only been awake for a few minutes that morning, but he was ready to go!
If you are building this kit, the instructions are here: http://electronicsmb.com/ElectronicKit.htm - look for "Class 4: Building Kit / Soldering"
|Opening the bag...|
|The ATTINY ready to be soldered...|
|Carefully soldering IC pins, and commenting that Dad's Hakko iron is MUCH better than the Harbor Freight iron he started with...|
|Its not in his mouth, just the photo angle...|
|Inserting the LEDs - with the correct polarity|
|Inspecting the LEDs to make sure they are flush...|
|all the LED leads are bent over...|
|Someone just learned that LED leads stay hot for a while... He's not letting me see that it hurt... I feel bad, but it is an essential part of learning - I did not hold his hands - he built it himself.|
|Sometimes the solder gets stuck in the joint - don't remove the iron and the solder at the same time - keep the iron on the joint for another second after removing the solder...|
|Soldering in the resistors...|
|Finishing up the with the capacitor and switches...|
|All components installed and soldered...|
|Battery pack soldered - the only component that is soldered on this side of the board...|
|Mounted in the box...|
