It Started With a Hardware Limitation I have been using Quectel GNSS modules in my designs for a while. They are reliable, well-documented, and the support ecosystem is solid. But the module I had been using had one problem that I kept running into: no external antenna support . For most projects that is a minor inconvenience. For a marine vessel monitoring and control system , it is a non-starter. A vessel hull blocks sky view, antenna placement is critical, and the difference between a clean fix and no fix at all often comes down to whether you can mount the antenna where it actually has line of sight. An integrated antenna in a sealed enclosure below deck simply does not cut it. So I went directly to Quectel. The Conversation With Quectel I reached out through their official sample request channel. I was not expecting much — most component manufacturers have a standard process: fill out a form, wait, get a few uni...
These days i am trying some experiments with infrared lights. Its not visible to naked eyes and normally uses a camera to see the light. If you want to try that, get an infrared LED and power it up and use a web cam or any type of camera to see it. This is interesting thing.
I use infrared to make a remote control. RX and TX side will have a micro controller. TX will send date to RX and RX will do the rest. Now the TX part is totally completed by experimenting, still RX side experiments are going on. cause i need to make the code looks nice and short. Once this is finished you guys can have a try... ;)
