New toy: RTL-SDR v3 complete bundle #SDR

Migrated all of my projects to #VisualStudioCode, can now develop under one IDE. Works much faster too, a 300K lines of code project of mine builds under 15 seconds on 8 core i9/16G compared to 37 seconds on Eclipse. Should have done this long ago..

Useful LoRaWAN airtime calculator; helps calculate the max daily transmissions per SF/payload size to comply with @thethingsntwrk fair access policy #IoT #TTN #LoRaWAN –> https://docs.google.com/spreadsheets/d/1QvcKsGeTTPpr9icj4XkKXq4r2zTc2j0gsHLrnplzM3I/edit#gid=0

The new #LoRaWAN antenna works pretty well, consistently receiving packets from a Moteino M0+RFM95 with a 82mm plain wire as antenna parked 13km away, SF10, -117dB RSSI. Got sporadic receipts from ~20km away

@thethingsntwrk console shows my #LoRaWAN gateway as offline, friends confirm the same with their gateways. Is it something local?

Finally a proper antenna for my @thethingsntwrk #LoRaWAN gateway.

Fail of the day: @adafruit 's pi+3.5" 3D printed enclosure won't close. I have their older 3.5" TFT+touch version though, this was designed for the newer one.

The 170 EUR Hikvision thermal camera arrived, impressive 160×120@25fps quality

Debugging TTN/LMIC code with my new Atmel-ICE in @PlatformIO_Org, no more serial/LED for debugging 🙂

An Atmel-ICE landing on my desk @MicrochipTech, guaranteed fun time ahead. Planning on fiddling with Cortex M0 bootloaders as a starter.

According to @FedExEurope, I moved:

RFM95 with a simple 82mm wire as antenna has a much better range than the ESP32 TTGO LORA module with uFL antenna. Less is more? #LoRaWAN #IoT

#SAMD21 based Moteino M0 + rfm95 #LoRaWAN module + SPI flash sleep current around 12uA. Not great, not terrible. Wakes periodically to send data to The Things Network using LMIC Arduino library. #IoT Dropped to 8.5uA with "crystalless" option.. cool 🙂

Moteino M0 sending data to the @thethingsntwrk using RFM95 and LMIC library. Had to wire RST and DIO1 pins for full library compatibility. #IoT #LoRaWAN Battery powered 🙂

PLA fillament shipment undergoing quality inspection. #3Dprinting

Wondering why @LowPowerLab Felix decided to use non-standard PCB thickness of 1.3mm on the Moteino M0, can't use a standard RPSMA connector

#3Dprinted an enclosure for a TTGO #ESP32 #LoRaWAN node, not a very good fit though.. will try alternatives

Experimenting with SAMD21D posing as a mass storage device using @Adafruit's TinyUSB library – planning on using this feature to expose configuration JSONs #IoT Added external SPI flash and using it as R/W mass storage device, works nice and smooth 🙂 Firmware configurations are now esposed as JSON file when you plug it in a…

Just received a @LowPowerLab Moteino M0, will use it with the RFM95 #LoRaWAN module I tweeted earlier. Has the SAMD21 Cortex M0 uC, a good chance for me to learn more about these. #IoT

Received few RFM95 #LoRaWAN modules to experiment with #IoT

Ordered a 80cm 5.8dBi antenna for my @RAKwireless RAK2247 based #LoRaWAN gateway.

Moved my TTN #LoRaWAN gateway to the roof, should have much better coverage than indoors.

When someone rips your idea and presents it like thei own. Left the copycat, right my original 2017 project

Drove around Sofia and suburbs with one of @boyannedkov #LoRaWAN GPS trackers, impressive coverage for a 20mW RFM95 transmitter. Managed to reach a gateway 32km away, practically no blind spots. External antenna, pictured below. #ttn #ttnmapper

3D printing a T-Rex skeleton for the kids (including the grown up kid tweeting this)

#3DBenchy printed in 1h 45min, using 100% default settings as I have no clue what they mean yet. Result is pretty good for what I care. Creality Ender 3 V2, Cura

64.4 dB noise level while 3D printing #3DBenchy on my new Creality Ender 3 V2, mostly fan hum. Stepper motors are barely hearable.

Just received a Creality Ender-3 V2 3D printer, my first. Hope it works well.

Stocking on gadgets in anticipation of another lockdown in the winter.. mostly IoT and engineering stuff. The bad thing is my Aliexpress wishlist has ~200 more items..

Completed a 4 EUR #LoRaWAN gateway enclosure for outdoor use using PVC fittings. Apart from the aesthetical crime being committed, it is pretty cool. #IoT
