Using the new RGB color sensor available at DFRobot, I rigged up a simple proximity alarm. I can use this to warn me if someone is in a close range of my Christmas tree putting presents under there. “Why not use a sonar sensor?” I hear you cry. Well, you easily could, but you...
resistor, R3, which drops 10mV at the maximum-allowed current of 100mA, senses the battery current. Op-amp IC2amplifies this 10mV drop with a gain of 128 and presents a threshold voltage of 1.28V at IC1's feedback terminal. Thus, the circuit maintains a 100mA battery current until ...
consistent with the ARRL handbook although it's wording is a little confusing. The only problem I have with the handbook is the labelling of the current transformer. There is simply no difference between a current, voltage or impedancetransformer.See more on transformers at the bottom of this ...
“no peeking at the presents,” “happy new year,” “warning warning this tree will self destruct,” “my other tree is aHanukkah bush,” and “all your gift are belong to us.” Additionally, one of the phrases, “i am showing off my programs,” begins a demo mode that cycles thro...
