One blew over the hornet’s nest

Posted on January 30, 2020 by james

I had a stack of hive brood chambers containing old comb that I was going to melt down. It must have been bumped by a deer or something like that, which left room for some hornets to get in and … Continue reading →

A couple more photos of the observatory

Posted on January 30, 2020 by james

I found these the other day, so I thought I’d just add them out of interest… First, the remote control for the telescope room LEDs. I keep meaning to 3d print a little holder for this to fix to the … Continue reading →

Swimming, 30th January 2020

Posted on January 30, 2020 by james

Another repeat of the same set. Busy pool again, too. I failed only on rep 16 of the 50m set, but wasn’t unhappy as my times are really starting to get back to where they were now — I had … Continue reading →

Posted on January 30, 2020 by james

Now my dew heater controllers are finished I need to get some more heater straps. Whilst casting about for suppliers I came across W&W Astro who I’d not heard of before. Their straps appear to be film-based and what comments … Continue reading →

Posted on January 29, 2020 by james

I’ve been meaning to post this for a while. Just a photo of the Stevenson screen, as complete as it’s going to get for the time being.

Posted on January 29, 2020 by james

Same set again, and by contrast with yesterday I had the pool to myself for a fair part of my session. Today went pretty well. My times were probably quicker on average throughout the 50m reps than they have been … Continue reading →

OWFS on a Raspberry Pi

Posted on January 29, 2020 by james

I have an old Raspberry in my Stevenson screen and I’d quite like to hook it up to my 1-wire weather sensors rather than running the 1-wire connection into the observatory to my desktop system there. OWFS looks like it … Continue reading →

Swimming, 27th January 2020

Posted on January 27, 2020 by james

Same set as last week today, but in a far busier pool. I wonder how many are on their post-Christmas fitness binge and will run out of steam over the next couple of weeks… Another improvement on my previous session, … Continue reading →

Summary of Robert Brown Arduino dew controller build

Posted on January 27, 2020 by james

Overall I’m very happy with this project. It seems to work very well and is a huge improvement on not having dew straps. Generally it’s a pretty straightforward build with nothing really that much more taxing than making sure LED … Continue reading →
