content: Hey There Guys.You might not know me cause I stayed in the background as of today. But I've been following the EEV-Blog for many years and consider myself a huge fan of Dave's. Forums are usually not my kinda thing, but I think this is the right place to spread what I want to show people.I'm into electrical engineering since my childhood and I'm building up circuits for around 15 years. I've spent the last year building up my new lab and have started recording some of my projects on camera since last summer. Just a few days ago i decided to finally upload some of the videos to Youtube. As of today 10 Videos are online on my new electronics-channel "The_Post_Apocalyptic_Inventor". These videos took many hundrets of hours to make. Its not your average "shaky cam 240p no effort what so ever kinda video style" (if you know what I mean ;P ).8 of the 10 videos I uploaded so far are RFID-related projects:"Hidden RFID-tags in Your Everyday Life" is a video which I made after discovering a hidden RFID-tag in a sweater that i had just bought. In the video I also explain the principle workings of RFID:"The RFID tag detector" is a detector with which you can determin if 13,56 MHz-RFID tags are hidden in Your stuff. The whole project has 4 Videos and goes into a lot of details of how to build the entire device."The RFID Zapper" is a mobile device which is capable of "zapping" (destroying) RFID-tags. 3 Videos deal with it. 2 of the videos are quiet theoretical but explain the idea and the workings of the circuit as well as some basics about boost converters in great detail.I hope that You don't think that I use this forum simply to promote my stuff. I really want people to know about RFID and that it has some implications you simply should be aware of. I'm also working on numerous videos at the time and a lot of stuff will come up on my channel soon. Most of it will be about switched mode power supplies, home made wind turbines, repairs, reverse engineering projects, welding machines, but also tutorials to different stuff. But all that stuff has an implicit massage that is more important than myself: "Know your electronics to live in a world of ever growing complexity (and surveillance) , be self sufficient and reuse things that are viewed as garbage by others(which helps save the planet) !"So I hope that some of you guys find the time to watch some of the videos and tell me what you thinkg. On Youtube or right here...Kind regards and greetings to Dave and alle the members.The_Post_Apocalyptic_Inventor

content: Welcome to the forum.hrmmm... First post and you broke Dave's forum already.. you'll get banned for sure now.I haven't viewed your videos yet but I intend to. I'll let you know what I think afterThanks!

content: Well I didn't even see that. Let's hope that Dave (should he stumble on it) will be in a somewhat "less agressive" state of mind than for example in his rant-video about Google+

content: I liked your videos, well done!I especially liked your detailed descriptions of the circuit schematics, and the way you used the video to display partial sections of the schematics and added components or removed components as you explained it, showing options to build and detailing the circuit description.I liked in the video 3 that you described your thought process you went through for deciding on which topology to choose to reach the necessary voltage. These kinds of details are often lacking in online engineering videos, where as I am the type of person who knows there are always 10 different ways to do something, and I like to know why an engineer chose one way over another, because this is something I can learn from and use in the future. Too many videos online are simply "how-to's" but do not discuss "why". That's the main reason I like Dave's videos and the forum here, it's full of "why"EDIT: I just wanted to add.. The lengths are great.. 10 min chunks.. I can fit them into my scheduleEDIT2: just watched part3 "How to build..." ..Great to see your math calculations and the circuit operation again ! +1 for using an old Flott braceCheers!

content: Hey. Thank you for the kind words.I like to hear that you like the parts were I explain the circuit while fading in and out different sections of the circuit diagram. See I used to read a lot of the old hobbyist books from decades past. The good thing they almost always had was, that the inner workings of the circuits were always explained step by step. I really like that. The only thing that always bothered me was that most of the time there was only one picture of the entire circuit instead of many smaller pictures with the different functional units were explained first and only then leading to the entire "symphony" of the combined parts. When I started to edit the videos I thought that now, were everybody can make films and little animations we really should use this advantage of "moving pictures" over the still images of the books from back then. When new videos will be coming out in the next weeks I already know that I will use that kind of step by step approach.I find also true what you said about the decision-making -process of choosing the right topology for the circuit. When I started filming I soon had many hours of material showing me soldering in some parts here or screwing in some screws there and so on and so forth. But when reviewing the material I wondered if that is really interesting to other people. At the end I left out 90 % of the "making-stuff" because I thought that, if someone really wants to work with this circuit in their lab or even build an entire device, they will use a different enclosure anyways and will solder the parts in differently, maybe on a varioboard of different size, or even a PCB. So I thought I would concentrate on the thought-process this time, rather than showing a lot of things that will be done differently by everyone anyways.I guess I will find the right mixture of theoretical and practical content in the future as I do more stuff.Concerning the Flott-brace: That's the "post-apocalyptic-style" if you know what I mean ;P
