Very interesting and useful module. I used a similar set of modules to implement a temperature, humidity and soil moisture monitor for my wife's greenhouse. Remote monitoring seems to be a perfect application for these modules. After your last video I checked eBay and found a slightly younger vintage Lionmount CD-4 capacitance decade for sale at a reasonable price. I purchased it and now have a hobbyist grade capacitor standard of my own (after a minor repair and a good cleaning). They did improve the bracket for the 10 uF decade by the way. Regards, David
This is meant as a big complement... This subject is not of my interest. However, knowing your excellence, I watched the video. And, yes, you did, indeed, make it very interesting, understandable and useful. Bravo! You never disappoint.
Guilty as charged (pun intended). The cap accidentally moved one position to the left and covers the (solid) 5V connection to the IN pin. The cap was supposed to be between the GND pin and +5V instead. Well spotted.
Interesting! I bought a pair of EBYTE E22-900T30D LoRa modules for an air-to-grown telemetry project, but that is still on the back burner for now. Good to see the details of your experiment, and I'd like to see more if you built it into a more practical device.
Very interesting video, thanks. is i possible for you to share the code for your Ping Pong programs. I have an application to use the RYLR998 modules to comumicate from a Raspberry Pi to a PC and have no idea where to satart with the code. Best regards Doug.
You need to use a serial interface to talk to the modules. The exchange is simple test strings. Commands are preceded with "AT+" . The problem is that the serial input wants very low voltage (not standard RS-232) so I used these USB to serial converters. The code is really simple. Send me an email and I send it back
Hi...off-topic, but I wondered about your GPIB-nano project... Is it done in Arduino IDE? Do you think it would be feasible to port it to STM32, or ESP32? Meanwhile, since I found your YT channel, by a roundabout route from elektor... Looking like I should have a ponder at your videos 🐻
I have no idea what was used for developing the code, sorry., I just used it. Also, I have since reworked my adapter to use the AR488 design and software. More here: github.com/Twilight-Logic/AR488 . I am using that for more than a year with 5 or more GPIB devices and it works great
I’m interested in LoRa and your other videos but also think you have a lovely voice; very similar to the late German-born British scientist and TV presenter Heinz Wolff. en.m.wikipedia.org/wiki/Heinz_Wolff

looking at the diagram at 2:49 - how do you get 5V from FT232R USB module to the LDO? Via capacitor? Seriously? ;-)

I like these usb to serial interfaces. I use a lot of 'em.
