Updated to add: In the schematic at 2:49 the cap accidentally moved one position to the left and covers what should be a (solid) 5V connection to the IN pin of the regulator. The cap was supposed to be between the GND pin and the +5V instead. Kudos to viewer "zyghom" for spotting the error.
REYAX provided me with the RYLR998 LoRa transceiver modules. It turns out these are well documented and very easy to use to exchange data over a radio link while needing very little power. They are perfect to obtain data for example from a battery powered remote sensor like a for example a weather station.

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

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

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.

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.

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

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.

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
