Sorry guys, I had forgotten I hadn't finished this series. Just found the circuitry in my pile of bits so I thought I had better complete the task. I have simplified the circuit compared to the one I used in the previous episode as I realised I was over-engineering again and there was a easier option. I placed the unit at the front of the car to keep it clear of the driven axle and rubber band motor but this could be tidied up and reduced significantly in size if you wanted to make a similar item and mount it at the back to use the weight to help the wheels grip. I prefer the floor mounted option that I demonstrated in the previous episode as there is no weight penalty for the car. Part 1 was a "proof of concept". Part 2 was the floor mounted release Components - 1 Harvested infrared sensor 2 2n2222 transistors 2 1k resistors 1 LED 1 diode 1 relay 1 home made coil for the electromagnet 1 neodymium magnet 2 9 volt batteries I have created a playlist for this series Remote release for rubber band powered car https://www.youtube.com/playlist?list=PLA5a2xPRSrB0bfyye--lJqxps5jqnk9db Rubber Band Power playlist https://www.youtube.com/playlist?list=PLA5a2xPRSrB1otXh0w36OwsYIHZznUWp6 Rubber Band Powered Car #8 https://www.youtube.com/playlist?list=PLA5a2xPRSrB0zJ5RHjvsw46Mio6uJjF5_ Rubber Band Power Cars https://www.youtube.com/playlist?list=PLA5a2xPRSrB3g5RiX8Kf_uUBOL0Tb7AS0 My Channel page https://www.youtube.com/user/GrandadIsAnOldMan Oldest videos https://www.youtube.com/user/GrandadIsAnOldMan/videos?flow=grid&view=0&sort=da Most Popular https://www.youtube.com/user/GrandadIsAnOldMan/videos?sort=p&flow=grid&view=0 Newest videos https://www.youtube.com/user/GrandadIsAnOldMan/videos?sort=dd&view=0&flow=grid Playlists https://www.youtube.com/user/GrandadIsAnOldMan/playlists?flow=grid&view=1 I have thousands of videos on YouTube, to find one try my search guides https://youtu.be/ceBSOoOHcgw or https://youtu.be/Zj4UgwkwYRk My "GrandadsOtherChannel" channel is generally where I will host the videos that give extra detail or longer versions of the videos I post on my main channel https://www.youtube.com/channel/UC2mp_L8RoxMyw3ewwSecZ6Q Facebook https://www.facebook.com/grandadisanoldman/ Merchandise - Check both of these links if you are interested as the prices will vary and the shipping charges will be different. http://www.redbubble.com/people/grandadiaom/portfolio http://grandadisanoldman.cottoncart.com/
