 +====== ESP32/​esp-idf LoRa project quick start ======
 +
 +[[esp32-espidf-lora-quickstart|{{:​lora:​rfm95-lora.jpg?​direct&​400 |}}]]
 +
 +If you need to bang together a quick LoRa-based project on an ESP32 using esp-idf (not Arduino) so you can get going in a hurry, follow along here.
 +
 +The focus on this quick start is to aim for 915MHz. Our setup will be configured to pull Meshcore packets out of air configured for the Australian NSW/ACT Regional settings. But you can easily change this for your region.

 +====== Attending ElectroneX 2026 ======
 +
 +[[electronex_2026|{{:​electronex:​electronex-sign.jpg?​direct&​400 |}}]]
 +
 +Last month I attended ElectroneX 2026.
 +
 +For years I've been wanting to go to an [[https://​www.linkedin.com/​company/​electronex-australia|ElectroneX]] show but every year something always gets in the way.
 +
 +This year I got in touch with the Professor to see if he was keen to go. He definitely was, so we made a date of it.
 +
 +ElectroneX is all about where businesses come together. If you're looking for ready-made parts to bring a product to market or to find vendors supplying connectors, components, small-form factor boards, this is the place to be.

 +====== The first few weeks with the Commodore 64 Ultimate ======
 +
 +[[first_weeks_with_the_commodore_64u|{{:​commodore:​c64u-in-place.jpg?​direct&​400 |}}]]
 +
 +Only the very astute among you would have noticed that I've been on a bit of a Commodore fanboy high since July 2025 with the resurrection of [[https://​www.commodore.net|Commodore]] and the production of the [[https://​www.commodore.net/​category/​computers|Commodore 64 Ultimate]]. ​
 +
 +There are probably hundreds of reviews out there already. I've deliberately avoided reading any just yet while piecing this article together. But if I happen to wind up covering the same stuff... well, then I do. I wanted to write from the perspective of having used the machine for a number of weeks.
 +
 +Short version? I'm still loving it!

 +====== Nordic NRF9151, Zephyr Message Queues, C++ and troubleshooting the less obvious ======
 +
 +
 +[[nrf9151_zephyr_queues_cpp_trouble|{{::​zephyr:​nrf9151-module-wire-mess.jpg?​nolink&​400 |}}]]
 +
 +Recently I worked on a product solution using a development platform based on the Nordic nRF9151 chipset, which was my first foray into Zephyr.
 +
 +I needed my ISR to put items in a Message Queue.
 +
 +And here is a where a problem occurred. This is a story of troubleshooting the not-so-obvious.

 +====== My time at Commodore ======
 +[[my_time_at_commodore|{{:​commodore:​commodore-building.png?​nolink&​400 |}}]]
 +
 +When I reflect back on my career, there have been quite a few special and golden moments. ​
 +
 +One of my fondest experiences goes right back to the start with Commodore Business Machines in Lane Cove.
 +
 +So how did I get to be at Commodore? And what was it like?

 +====== Hacking Region Free DVD on the LG LHB655NW Home Theatre ======
 +[[hacking_region_on_lg_lhb655nw|{{:​lhb655nw:​lhb655-region-menu.jpg?​nolink&​400 |}}]]
 +
 +Unlike the rest of the streaming world, I like to own my things. Unless the cancel-culture-woke-folk start making house calls I can continue to enjoy Season 2, Episode 4 of the IT Crowd on DVD. Streamers can't.
 +
 +I recently picked up the complete DVD collection of The Fast Show from the BBC for a very good price but it was Region 2. I'm Region 4. So began the journey of looking for codes and remote sequences to try and hack the region.

 +====== Build your own Mobile Phone with the LilyGo T-A7670SA ======
 +
 +[[build_your_own_mobile_phone|{{:​t7670sa:​t-7670sa-held.jpg?​nolink&​400 |}}]]
 +
 +I'm not a smartphone user, and I rarely carry my little feature phone. But since Telstra shut down the 3G network, my perfect little flip-phone from 2010 gave me a big hug and moved away. Nothing has come close to replacing it.
 +
 +But what if you could build your own, the way you wanted it? That would be pretty cool.
 +
 +During the last few days I've been looking through the LilyGo T-A7670SA'​s vast feature set: Bluetooth, WIFI, LTE, GPS, USB, solar charging, condenser mic input, speaker output, 18650 Battery Holder, TF Card slot, SIM slot and plenty of GPIO.
 +
 +I'll walk you through how to work with the board, what to solder, how to send/​receive SMS and how to send/​receive calls using just the stock firmware. No code required.
