I rarely use Arduino nowadays, one reason is its amateur-ish IDE. Thankfully there are alternatives like using it within Eclipse C/C++ IDE, which partially deals with my Arduino intolerance in the rare cases I resort to it.
Had to increase a WiFi AP association timeout on an ESP32 project, it was failing to connect in <15 sec. What is the recommended time to wait before considering a connection attempt timed out?
Dealing with bugs..
Added a software low-pass filter on a remote humidity sensor's readings, the result is quite obvious
New post: Thoughts on structuring a productive software development team https://wp.me/pawL3e-1kv
I recently spoke with a friend of mine, who is now a software development team manager in a Fortune 500 listed company. He shared with me that his managed teams work using agile methodologies and consist only of software developers.…
Knowing what PE2 is is a sign of aging says a colleague with irony.. oh, well, not only do I know what it is, but I have used it for quite a while back then.
Got one of the WROOM-32 downloader boards, may come in handy.. #esp32
Considering creating a new LoraWAN based product family, targeting industrial and agricultural IoT
Toying with an old project of mine, a RFM69 based keyfob. Added support for it to my DIY sliding door opener to act as a backup, when the Internet is down and I can't use the app on my phone

Injection molded enclosure for the ESP32 based thermostat controller, looks and feels pretty neat #IoT
Interfacing an ESP32 gateway with a wireless 433Mhz fire alarm, see it in action https://youtu.be/4-7YdF4ifOU #IoT #esp32 #smarthome
49mA with display off and maximum wifi power savings + DFS enabled while maintaining WiFi and 433Mhz connections to low power battery sensors Note that this is at 5.12V or roughly 80mA on 3.3V; CPU speed varied between 160 and 80Mhz as needed
I've kept myself busy the last few months according to my Github contributions stats, working mostly on private repositories
It is just me, or @Google's Chrome 404 error title has an extra '1' instead of '!' ? Someone's Shift key must have slipped. I find it cute though, shows that there are humans behind it.. #bug #Google @Google Version 76.0.3809.100 (Official Build) (64-bit)
Uploading firmware and other partition items like CA/client cert, cert key, NVS partitions, espfs images using @SpritesMods's esphttpd project https://github.com/Spritetm/esphttpd #ESP32
Upgraded my ESP-IDF to v3.3-rc, expecting the upgrade to v4.0 to be PIA given the number of material changes #ESP32
Added GUI to show serial debug output to the TFT https://youtu.be/19-C5f2eHmQ #esp32 #iot #lvgl #embedded
Reminder: the "S" in IoT stands for Security
Our 13m³ pool water temperature reaching just over 30°C thanks to the DIY solar heater I blogged about last year https://harizanov.com/2018/07/diy-swimming-pool-solar-heater/ solar harvesting
Node-RED deserves more than this.. https://x.com/knolleary/status/1159172242665811968
Considering moving all graphical resources (icons, fonts) of the TFT32 thermostat project to dedicated OTA update-capable partitions to allow GUI branding and customization. Few technical challenges to do so, but completely doable. PoC of that done, and working well. As a result of the decoupling of graphical resources from the code, the OTA image for…
Can't think of a reason why anyone would need an ESP32 emulation in QEMU, but TIL that it exis https://github.com/Ebiroll/qemu_esp32
Three ways of provisioning an ESP32 with WiFi credentials: smartconfig, AP captive portal, and GUI: https://www.youtube.com/watch?v=UNdZGgIRWVo
It's close to a year since I started working on my ESP32 based thermostat controller/gateway project with TFT display. It now has 120K+ lines of code (components included), work done entirely at nights/weekends. What's the longest you have worked on a passion project? #IoT https://x.com/mharizanov/status/1027868368500666368
Got one of these for my 10 y.o. daughter, a good introduction to the world of embedded #microbit
https://mqtt-explorer.com/ looks quite promising, I need to take a closer look #MQTT #IoT
3D printed enclosure prototype for the ESP32 based IoT thermostat controller project I have been tweeting about recently #esp32 #MQTT #smarthome #homeautomation #IoT #3Dprinting #design #Mechanical Need to adjust the UI for the display cover curves..

Using ESP32 generated QR code with AP credentials -> captive portal to configure the WiFi STA configuration in 5 seconds.. #IoT Isn't that cool?
I didn't know that Samsung S8's camera app has built in QR code recognition, just pointing it to a QR with AP login details prompts connection UI..neat
