Indoor Environment Monitoring with LoRa, Part 3
It’s now time to start playing with the sensor node. I have a BastWAN set up with the CJMCU-8118 sensor board, and a small OLED to check how things are working, since it won’t be connected to a computer. So it’s now time to work on the receiving side. It’s pinging data as PING packets…

Indoor Environment Monitoring with LoRa, Part 2
As I said in Part 1, the second instalment is going to be quick and easy: setting up a BastWAN with what’s needed to serve as an environment sensor: a breadboard, a CJMCU-8118 (HDC1080/CCS811 combo sensor), maybe a small OLED, and we’re good to go. This comes however with a twist, and it’s going to…

Indoor Environment Monitoring with LoRa, Part 1
This is a multi-part blog post and tutorial. Today I will explain the goals, and what will be used. The next part will be very short, as we’ll be using BastWAN_Minimal_LoRa, see below, which makes it an almost zero-conf task. Then we’ll move on to the receiver, and display of data – which will require…

And of course I bought another Yagi…
In my previous post, I showed off my first yagi, a (supposedly, anyway) 433 MHz antenna that could double as a rake, and bird stand (and I sure hope seagulls and eagles don’t read this…). I had very good results with my ESP32-based LoRa devices (TTGO and T-Beam), and was looking forward to buying another…

So I bought a Yagi…
And it was great. So you can stop reading now… 🙂 Nah kidding. I have been wanting to try a Yagi antenna for a long time… I have had this very antenna for more than a year in my shopping cart: back then I was wondering where to install it in my previous flat, a…

LoRa.asm
Last October (2020) I started a project to enable LoRa on my Sharp PC-G850V pokekon. It had many moving parts, and required things I don’t have the skills for – namely electronics. But fortunately, the guy who dragged me into retro-computing, HWR0, came up with the tools I needed: a serial adapter, so that I…

Vos papiers siou plait ? Tu rigoles…
Vous voulez voir une frontière bien trouée ? Oh oui oh oui ! qu’ils disent. Bon d’accord. 🙂 Il y a un bled dans l’ouest de la Thailande qui s’appelle Mae Sot. Juste à la frontière avec la Birmanie. C’est l’un des points majeurs de transit entre les deux pays – fret, visiteurs. Jusqu’à Covid,…

LoRa Overwatch
So far, when doing tests with my BastMobile and a couple of BastWAN devices at home, using my BastWAN Minimal LoRa firmware, I connect the home BastWAN devices to my MacBook via CoolTerm, and log everything that’s happening. When debugging it’s convenient, but it’s not exactly user-friendly. Then again, I’m the only user, so… 😉…

SPI with the PC-G850V
I have been (vaguely, code is incomplete, but “works well enough”) able to send and receive LoRa packets on my Sharp PC-G850V by connecting it to a BastWAN, via a Serial board designed by HWRØ. In a way, it’s impressive enough, but somehow it feels like cheating: I am after all only exchanging strings on…

Back-buffer: Removing flickering from animations
When it comes to GUI and graphics, I’m a rightie with 2 left hands: hopeless. So here I was trying sample code for the Wio Terminal, a simple sketch called Simple_UI, and that thing didn’t do anything except displaying rectangles and circles. I was disappointed. So I decided to make the “UI” work as intended:…
