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.

Also, note that if something has a battery in it, it pretty much always means stress with sending them. These rules seem arbitrary and subject to constant change, so where possible, we'll ship things without the batteries and let you find one 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.

Thanks for covering the Bee Motion S3! I appreciate it.

Thanks for yet another enjoyable video with plenty to unpack. As somebody fairly new to the hobby I appreciate the Gift Guides as plenty of neat items that even a novice can buy to start making some fun projects. Congratulations to the winner of the competition with thanks to the sponsors for their generosity! Very impressed with the Nordic Thingy 53 project as well...

Thank you for the PoE & STM32 guide links. Both very interesting.

The #nRF21540 would be helpful for understand BT mesh configurations.

Another great video Ian. Hope you enjoy your return to blighty!

First, thanks for selecting me as the winner of the PPK2. My Blues Notecard project hardware should be built by mid-January, so it should be ready for profiling :^) .#nRF21540 If I were lucky enough to win that kit, I'd implement a long range BLE control project like Naveen did with a Thingy:53 which also has the same RF FEM.

#nRF21540 Currently, my home automation relies mostly on wifi (esp8266) that I've programmed myself. I start to get more and more BLE devices. For reasons of range I want to look at a mesh network, but a range extender would probably be the best solution.

#nRF21540 I would like to try to convert some of my garden control/sensors over from wifi to something else (Bluetooth)

Am I knowledgeable? 100mW EIRP is EU legal regulatory max power for 2.4GHz. US is 2.4GHz ERP (the I in EIRP makes a HUGE difference) so EIRP is equivalent isotropic radiated power - so the transmitted power through the antenna is expanded to a sphere, i.e. your antenna is directional and you're transmitting at 10mW if you expanded the radiation pattern to a full sphere and then it would transmit at more than 100mW, you're operating illegally ... (in the US ERP means your antenna can transmit at 100mW as it leaves the antenna) #nrf21540 make a WiFi killer for other people's homes using a yagi ...

#nRF21540 will be nice in my energy harvesting water quality measurement proje t that i use to monitor water quality of my home
