20 hours of driving. 7 hours of charging the car. many waffle houses. roadkill/jerky. one reboot of a tesla.  windshwind wiper software in beta. one trip down the runway of  the shuttles landing strip. and here we are. 3hr to go to the kaboom

Up until now it has been believed by many that the laser-pointer and the cat are a marriage made in heaven. The ‘click’ of the button makes a tiny sound, imperceptible to human ears, and your normally lazy feline makes a beeline for it.

I’ve been working on upgrading one of the gadget army, and this requires booting its u-boot from serial (using xmodem!) over a pretty neat protocol ‘kwboot‘ (allowing you to unbrick even the hardest bricked marvell kirkwood device).

And, um, well, watch the below video (its an asciinema movie using my plugin for wordpress, so hopefully it works for you. Go ahead and select some text in it!). Sleepy desk cat became beserk cat. Its like a laser-pointer to the next level for him.

So an update on the earlier radon gadget. I received the BLE sniffer widget, but, wow, its a bit complex to use. Keeping an eye on the basement Radon, and you can see, it fluctuates quite a bit. We are well under the ‘safety’ limit (which there is some discussion on, some being of the opinion there is no safe limit, others that if its similar to the outdoor levels you can’t do much better).

In Europe, the consensus seems to be 100Bq/m^3 is the threshold to start mediation. Here in Canada the consensus is 200Bq/m^3. My peak is 53Bq/m^3, with an average around 30. So good so far. But its deep-winter here, once spring starts and ground-water flows, maybe I’ll have an issue.

So, worried about your basement? A little more bluetooth gadgetry and you can know for sure. And yes, that test you did once years ago is meaningless, you need to test all the time, see my results.
