Perhaps need treadmills in the garage for 'indoor walkies'. Tim Hunkin: The Secret Life of Arcade Machines, Rent-a-Dog https://www.youtube.com/watch?v=ftOwZt8nA0w Some of the responder video footage from those wildfires is quite an eye-opener. Not a nice place to have to work or live. I was expecting some sort of a translucent flower illuminated by a combination of UV and visible light with some sort of sugar water dispenser. Was quite a surprise to see the simple target they had come up with. My bumblebee visitors don't take much notice of me. They are far too busy trying to visit every flower in turn a hurry to get back to the nest.</description></item><item><title /><link>https://community.element14.com/members-area/personalblogs/b/ralph-yamamoto-s-blog/posts/bees-in-oregon-2026?CommentId=911d798c-446a-4d20-b672-034043181764</link><pubDate>Sun, 09 Aug 2026 16:34:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:911d798c-446a-4d20-b672-034043181764</guid><dc:creator>ralphjy</dc:creator><description>Our AC does a reasonable job of keeping the air clean and we have a couple of portable HEPA air filters that we move around as required. Mainly have to stay indoors all the time and the poor dogs have to forego their walks. Primary issue is that we still get throat irritation even with trying to mitigate outdoor exposure. Not sure if it is small particulate or gas content - probably both. Really feel for the firefighters and people living near the wildfire areas. Wind shifted yesterday and air quality is much better now, hopefully will continue this week. Thanks for posting the pic of the bee pattern, saves me from looking for it. Based on the verbal description, I had expected something different. I may have to try it to see how well it works when there are lots of flowers around. I know that I get a lot of company if I sit outside at lunch with a smoothie .</description></item><item><title /><link>https://community.element14.com/members-area/personalblogs/b/ralph-yamamoto-s-blog/posts/bees-in-oregon-2026?CommentId=e0378b8f-ccb1-4884-b498-52f8b2d43ee6</link><pubDate>Sun, 09 Aug 2026 00:14:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:e0378b8f-ccb1-4884-b498-52f8b2d43ee6</guid><dc:creator>beacon_dave</dc:creator><description>Have you got any air filtration in place in the house to try and improve the air quality indoors ? I guess honey bees are used to smoke from beekeepers tending to their hives. Getting the bees to come to a camera isn't easy, especially when there is a garden full of flowers to distract them. I'm surprised by the OSU bullseye pattern. Most of the bumblebees here head straight for particular flowers with little interest shown in anything else. I would have thought you would need to replicate the visible and non visible-spectrum of particular flowers in order to distract them. The Melittologist course is an interesting find. I guess there won't be much technology covered in the Bee Steward course but it may open doors for networking with people that are researching it.</description></item><item><title>File: Saving a bee with sugar waterhttps://community.element14.com/members-area/personalblogs/m/managed-videos/151562Sat, 08 Aug 2026 21:12:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f44d0c91-081d-4c17-852d-d54091b4f993beacon_daveOne of our VIBs sent in this amazing video of a bee he found in need of a little energy boost.

Phenomenal pics. I've just been trying survive the heat and unhealthy air quality due to wildfire smoke. Doesn't seem to bother the bees much other than prematurely aging all the flowering plants. Hope there aren't long term negative effects for the bee population. I recently learned that Oregon State University has been using AI cameras to classify the different species of bees in various agricultural areas. They are using RPi Zero 2W's and use some method to attract the bees to the camera for a photo. I'll have to learn more about it. OSU has some interesting extension programs relating to bee studies (Melittology). Doubt that I can become a "Master Melittologist", but maybe I'll try an intro Bee Steward course . I might do a blog post about it, but I'm not sure how much interest there is in the E14 community besides you and me ☺ .</description></item><item><title /><link>https://community.element14.com/members-area/personalblogs/b/ralph-yamamoto-s-blog/posts/bees-in-oregon-2026?CommentId=36b7deb6-af4c-447f-8886-6f53d05aa3e0</link><pubDate>Sat, 08 Aug 2026 19:09:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:36b7deb6-af4c-447f-8886-6f53d05aa3e0</guid><dc:creator>beacon_dave</dc:creator><description>Some photos of new visitors to the garden here. Either the bumblebees have started shaving their abdomens to stay cool in this hot weather, or I've perhaps got carpenter bees. I've got some new heathers coming into flower, so it will be interesting if I get any Heath bumblebees stopping by to check them out.</description></item><item><title /><link>https://community.element14.com/members-area/personalblogs/b/ralph-yamamoto-s-blog/posts/solar-power-hat-fan?CommentId=a07d5075-64ee-450b-8a41-99f3c22f9f99</link><pubDate>Mon, 03 Aug 2026 02:54:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:a07d5075-64ee-450b-8a41-99f3c22f9f99</guid><dc:creator>Gough Lui</dc:creator><description>I certainly had one of these.
