So after a year of electronics, I started going to class again, found a great teacher , she&amp;#39;s getting me on track, now on to calculus lol I&amp;#39;m not bored at all. Heck if I make 80 I just might know something. Becarefull if you pick up a book called ,the art of electronics, can really change and challenge your life. Thank you for your time.</description></item><item><title /><link>https://community.element14.com/challenges-projects/element14-presents/thelearningcircuit/w/documents/3679/wire-maze-game----the-learning-circuit-14?CommentId=46e2ab34-743f-4c6d-b45c-d216042cdfce</link><pubDate>Tue, 25 Nov 2025 23:08:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:46e2ab34-743f-4c6d-b45c-d216042cdfce</guid><dc:creator>rusty151</dc:creator><description>Thanks heading north to be with grandchildren in a week, been gathering all type of components, Sci kits so I know have something new everyday for them to creat and have fun with . It&amp;#39;s really amazing what you can put together for 50.00 , so far that&amp;#39;s the odd things I needed to get, but buying on aliexpress really helps keep the costs down. Grandma bakes them stuff, now grandpa can build fun things with them. May just get to number 1 granddad yet. The grandkids are getting fat spoiled and happy. So we are doing our job. So thank you ps grandma may not like it. But we will ignore that. Thanks again.</description></item><item><title /><link>https://community.element14.com/challenges-projects/element14-presents/thelearningcircuit/w/documents/5427/making-a-12-bit-dac-using-an-arduino----the-learning-circuit-96?CommentId=d02a8d45-da8f-4272-8885-a7d22a5e4957</link><pubDate>Thu, 19 Dec 2024 21:58:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:d02a8d45-da8f-4272-8885-a7d22a5e4957</guid><dc:creator>beacon_dave</dc:creator><description>The original project code can be found here: https://www.hackster.io/instrumentation-system/dac-8-bit-using-r-2r-ladder-964837 https://github.com/mfaliha/DAC-R-2R-Ladder-8-bit-Arduino-Uno Follow along with Karen in the video to make the changes.</description></item><item><title /><link>https://community.element14.com/challenges-projects/element14-presents/thelearningcircuit/w/documents/5427/making-a-12-bit-dac-using-an-arduino----the-learning-circuit-96?CommentId=784b7bfa-e788-4745-a7fb-a58e67ab9f33</link><pubDate>Thu, 19 Dec 2024 21:36:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:784b7bfa-e788-4745-a7fb-a58e67ab9f33</guid><dc:creator>Mandy2710</dc:creator><description>Where i can get code of it</description></item><item><title>Wiki Page: OpAmps Project: Build an Amplified Stereo Mic Kit -- The Learning Circuit 69</title><link>https://community.element14.com/challenges-projects/element14-presents/thelearningcircuit/w/documents/4790/opamps-project-build-an-amplified-stereo-mic-kit----the-learning-circuit-69</link><pubDate>Sun, 24 Nov 2024 20:22:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:c8965aa7-71f7-4518-91f3-aa848a4f5c90</guid><dc:creator>cstanton</dc:creator><description>OpAmps Project: Build an Amplified Stereo Mic Kit The Learning Circuit | element14 presents | Project Videos www.youtube.com/watch In the previous lesson, Karen talked about how op amps work and the many ways they can be used. In this episode, Karen assembles the Velleman MK136, Super Stereo Ear Kit. This kit uses a NE5532 Op Amp to boost the audio input from two onboard microphones to an audio output jack. While a speaker is not included in the kit, there is a potentiometer that acts as volume control. Follow along as Karen walks you through soldering the kit together and then see it in action!
