A small Wi-Fi, Bluetooth LE and IR testing gadget that feels more like a utility knife than a Swiss Army knife.

It's here.

While I was eating lunch today there was a knock at the door. It was the postie and she brought this! I backed the kickstarter pretty much as soon as I read it. I love a little RF gadget, and this is both little and an RF gadget. It only came today, so I've not had much time to play with it yet. I'll add some more detail to the review over the coming weeks.

The device is about 65x44x17mm and it weighs about 45gr. On the front there's 3 clicky push buttons and a 23mm screen. On the side there's an IR receiver and up top an IR transmitter. On the bottom there's a USB-C charger. Inside is an ESP32 C3 and a 500mAh Li-ion battery pack.

When you turn on the device for the first time it fires up a config WiFi portal, you connect to it and then provide details of your IoT internet. It connects, downloads an update then reboots. You do all the configuration of the device via the config portal. The controls are very self explanatory, left button moves left, right button moves right, middle button is enter; long press and it does back. There's 6 play with me menus and a 7th settings page.

The device is aimed at people wanting to explore the interesting posibilities exposed when you know how things work. The device makes it easy to get into RF exploring. The captive portal is a great starting point for explaining to your kids why joining public WiFi networks often isn't a good idea.

My initial impression of the device is that it's a great stepping stone from being not interested in cyber security to becomig interested. That's got to be a good thing? The documentation on the infishark website is very accessible. Written for the target audience, I've not looked properly, hopefully there's more detail if you dive in. I'll have a play with it and update this when I've got more to say.
