Alright, this post is about the most important thing about OSDYLS, the IR communication. Before I started this I already bought a bunch of IR diodes and receivers that other people recommended in their attempts or just looked logical to me. Meanwhile I believe this is the part where most of the DIY attempts got stuck. Lets go through these projects: Pewduino There was much time and energy spent on this project, including own PCB and more, my deepest respect! Luckily today, due to the availability a lot of *duino electronics, noone has to reinvent anything anymore. He somewhere wrote he would go for a 50mm lens . Reason: focal length. If you have a look at all these shopable lasertag toys you will notice a pretty small lens and IMHO there is a reason for this. If you start with a big lens you are able to transport more light to the target. True but it also starts with a bigger diameter and will end up in an even wider diameter at the target. I don´t see any advantage but I might be...
Okay here it is, one of the S2 mini, I ordered a batch of ten already. Yes I am positive about getting this done ;-) If not, it is possible to make a lot of other neat things with these little fellas. However I figured that I need a smaller soldering iron for this one, already ordered too. Meanwhile I did some research about the HC-12 radio modules. They have a quite long range but unfortunately it is not allowed to run them at max power here in germany . However Wolfgang Ewald wrote a pretty detailed description in his blog "Wolles Elektronikkiste" on how to get these things in a legal mode while still achieving distances over 100m so I won´t get deeper into detail since I am not an electronics specialist. At the final version I´ll just note down what I made and what components I connected how and why. For detailed specifications check Wolles blog, though it is in german ;-)
