Taking a second look at that sunflower

First, for the sake of comparison, here’s what the edge of one of the green bracts ringing the back of the sunflower’s head looked like through my 60x-100x-magnification clip-on microscope: Now here are two bract-edge photos taken with my 200x-500x USB scope (it’s a Measurement eScope DP-M07) at 500x magnification: I didn’t get around to […]

Exploring a sunflower with a cheap 60x-100x clip-on microscope

An inexpensive 60x-100x-magnification clip-on microscope like the one shown above can be a shed load of a lot of fun. Last Friday, I spent one of the shortest hours of my life (because TFWYHV) exploring a sunflower, one which I’d just lopped off its stalk, from a bunch that had brightened our home for the […]

If you give the MP3 file embedded above a play, you’ll hear me noodling around with my slightly modified version of the “toy organ” DC circuit featured on page 105 of Forrest Mims Engineer’s Notebook [ISBN 9781878707031]. Using alligator clips, I attached each of the three different types of small 8Ω speaker (left to right: […]

Wanna hear about the time that I bought four LM3909Ns?

… and they came wrapped in sock-foam-mesh fruit wrappers? Above: My four itty bitty LM3909Ns came sandwiched between two rectangular bits of pink (possibly anti-static) foam, wound inside a chrysalis of plastic wrap (UK: cling film) which was, in turn, lovingly cocooned within a mass of sock-foam-mesh fruit wrappers. And they’re older than you, assuming […]

Some Taobao merchants sell PTFE-coated wire and other sell little spools, but I couldn’t find any offering spools of PTFE-coated wire, so I got some of each and did the spooling myself. I neglected to include any known-size objects for scale but I the center-hole of one of those spools is just large enough to […]

Failure mode for a cute lil’ magnet: separation of chrome-y paint from magnet’s working surface

Another neat little magnet bites the dust and the failure mode, as usual, is the separation of the shiny chrome-like coating from the working surface of the magnet. So long, seal with stripey beach ball, I hardly knew ye.

Homework’s whack, and so are rules! Tucking in your shirt’s for fools!

Lots of portable electronic gadgets use Li-ion batteries, so I can understand why an Li-ion battery warning sticker would arouse the interest of thieves somewhere in the logistics chain between Amazon.co.uk and me. Fortunately, they weren’t interested in hot-glue guns and the holes which they poked in the box, including one through the Li-ion battery […]

Why is Genki Sushi’s hip-hop bear mascot sweating? Why is it making a finger gun gesture?

Why is the tissue-dispensing version of Genki Sushi’s new(ish) hip-hop/gangsta-themed bear mascot sweating? Does it want customers to use more tissues, faster? Or is it worried that restaurant patrons will exhaust its supply of tissues quickly and a staff member will thrust more into its maw? Other depictions of the bear bro are just as, […]

Interesting living (and formerly living) things … at the beach a couple of weeks ago

Better late than never is the principle at work here. I processed these images weeks ago but didn’t get around to posting them. Though I haven’t actually nailed down the identity of any of them, in some cases, I have a guess or two. There’s a lot going on here on this rock. The finger-shaped […]

A typhoon passed through Hong Kong recently. Afterwards, at low-tide time, I donned a pair of low-rise duck boots and headed down to the small beach nearby to see whether any interesting sea life had been washed closer to shore or, less-fortunately for the creatures concerned, ashore. I did see some interesting living and once-living […]
