FreeRTOS on the Pi Pico, Globe Trotting IoT projects, and more!

Welcome to the Electromaker Show episode 70! This week we look at a truly globe-trotting cellular IoT project and uncover another wonderful way the Pi can be used for music-making. We'll also take a look at some funding website things and learn all about low-power wireless communication!

All prizes not claimed within 6 months will be put back into the prize pool. Please note that some items may require payment of customs charges when they arrive in destination countries.

Unfortunately, we cannot ship items containing batteries outside of the EU, so where possible prizes containing batteries will be shipped without the batteries in. I'll do my best to document this process so you can source out something locally!

Electromaker contests are separate from the Electromaker store (I literally go to the post office to send prizes) so beyond giving tracking details there isn't a lot we can do if something goes missing.

Thank you for featuring our FreeRTOS guide! Very happy to hear people are finding it helpful

Nice UNO you have there! Perfect show to start my day at work. Mostly on headphones (in case bosses watching this show too) but got a glimpse of the UNO :D - also M5Stack devices are awesome, polished, portable and you can program them completely wirelessly via web browser (as well as ArduinoIDE) - do exclude this comment from the raffle as I already have the M5Stack Core2 - just not as tough

Thank you for another show. By the way I noticed Rpi pico turned one year old. For me it was the thing that open the door to microcontrollers for me and showed me that writing a little bit if code doesn't always have to be that hard. My interest in Python (programming) language came back and I am not afraid of little projects that can make my everyday life a little bit more comfortable and interesting.

Great video as usual
Thanks for sharing :-)

Great to see you back, Ian! I have just built a Winkey-compatible CW keyer using the ESP32. It connects via Bluetooth Classic to the PC/Laptop so there is no direct connection to a transmitter. The only problem was that there seems to be no Python library support for BT Classic so I had to resort to Arduino IDE 'C', which is a pity as learning Python has been fun.

Enjoying the shows as much in 2022 as in 2021, which is quite a bit. Hoping to get enough micro-controllers, particularly raspberry pi zeros, to be able to allow my computer class to work with them. Chip shortages continue.

I'm working with a couple of companies, one developing a neural link (EEG), non-invasive and only requires a small unit attached to head, then processing via ML. Also building private (initially data only) 5G network to support local uncontested data access.

Right now, starting a Voron 2.4 350mm3 printer build.

[Tarbard]

I like the pegboard, I need to do something like that.

[eliasfarciroli]

Thanks for the prize, the contest made me reflect a lot.Something I'm thinking about and how the world is becoming faster and faster, a lot of changes, a lot of unique things in a few months.

Got sidetracked with electronic music 😅 But if I look at the project in your show, the two hobbies may converge to some degree 😉

[SimpleDIYElectroMusicProjects]

Welcome back! Nice to see the show returning and I hope the family are doing well. I've been investigating the idea of sending MIDI data over I2C. So far I have a prototype MIDI "transport" for the Arduino MIDI library and a CircuitPython "driver" for the Adafruit MIDI library that I've used on my Raspberry Pi Pico and I've been investigating various MIDI routing options... I'm not entirely sure there is much practical use for it, but it's a bit of fun. There are some demos on my website and channel.

Great show as always. I'm struggling to work through this pandemic as I'm sure many others are. Lots of projects to do, but hard to stay focused...

[andrewbeasley]

Wonder if the cube is baby proof??? You need to explain to the good lady that it's a serious question that MUST be answered so you just HAVE to buy one 🤭
Currently working on my mental health - long haul trying to find the mountain range with the tunnel with the light at the end but your show gives me at least one smile a week 👍

[brothertiny]

With the chip shortage in full force. I'm starting to get more exited over the possibility of making electronic projects without a microcontroller.

[StephanLiebenberg]

When you see your comment on screen for the winners announcement, only to have it blurred out seconds later... disappointment was real 😪
Oh well, I ordered my first arduino starter kit, I've played around with the Raspberry pi's and I love them. I'm also working on my first Raspberry Pi Pico based robot, it's all built, now just to do the code 😬

[jmvoogd]

I'm playing with an FPGA, again. Maybe this time I will design my own simple CPU.

[ritvi]

I am working on a mental health based IoT project. If anyone has any experience in this area, please do reach out. I am struggling with multiple blocks of the project. Thank you!

[aristotelian]

Unfortunately, I am having to pack away all of my hobbies. With no budget and too many things going on in day-to-day life, we can't afford the distractions.
