  • Enhanced NRF24L01 Radio With a DIY Dipole Antenna Modification.

    Great work Ron. Your work gave me an idea for a long range NodeMCU ESP-12E ESP8266/antenna unit. Taking one of those ebay 15 element yag antennas, removing the plastic cap that cover the driven element, removing the driven element and replacing it that an ESP8266 with your modification. The antenna on the modified ESP8266 would then become the driven element. That should element a lot of loses and deliver maybe a +13db gain. The driven element that comes with the antenna is a joke. It consists of two pieces of brass shim stock and what seems to be some type coaxial cable of lead to match impedance. It will be at least a few months before I get around to trying it but I thought I would get the idea out there in case anyone wanted to take a shot at it. I also would like you thoug...

I also would like you thought on the attempting this. One of my main concerns is the location of the module relative to the rest of that antenna. Do you think it would be possible to increase the length of you antenna leads more that 6 mm. Basically, turning the lead in to something like twin lead maybe closer to 4" in length to move the module away from the antenna and shielding it. Any thoughts?

  • Cheapest way to connect arduino to internet

    Great article. How do you use a generic 3G/4G portable router? Do you still need to change it to DD-WRT? If so how do you find what version of DD-WRT you use for a generic 3G/4G portable router? These units seem to be quite different in that they are powered through a usb port. I guess my questions amount to how do you hook one of these up compared to a self powered non-generic router?
