Prototype USB to LED string PCB
Just the same circuit as the hard wired version, but with the convenience of everything just plugging together without chopping up USB leads.

This was a prototype, and in hindsight I migh...
2021-10-29 02:22:22 +0000 UTC View PostEggs are dangerous
I had a "special moment" today. I bought a pack of four hard-boiled eggs from a local supermarket and microwaved one for 30 seconds to warm it up for eating.
When I bit into it, it exploded and sprayed a jet of superheated steam which burned my top lip and has left it red and blistered.
I think I'll st...

Not just a single schematic, but three variants and hand built versions of each to test.

One was rubbish, but the other two were good.
These sticks can also apparently be used to de...
2021-10-28 01:53:28 +0000 UTC View PostNew PCBs (not a video yet)
Two orders arriving at once from JLCPCB (not a sponsor) with my first attempt at vee-cut panelisation.
The PCBs on the right cost a fraction of the PCBs on the left which incurred a significant processing charge due to their size.

It's a short video because there's not a lot to say about this.

The schematic didn't take long to draw.

I recorded this just before coming over to Glasgow.
https://www.youtube.com/watch?v=zxEFTXpnMAM
It's a decent effect. I think it may be a rebadged Premier product.

The smoke was extremely unpleasant this time. It made my eyes sting for some time afterwards.
2021-10-20 02:19:36 +0000 UTC View PostHEPA air cleaner - the video
This turned out really well. It's a low power and low noise air cleaning unit that simply uses a standard computer fan to pull air through a common HEPA filter from eBay.

I've just upgraded my simple air filter to use a common HEPA filter for higher air throughput.
Furnace style filters are much harder to get here due to our hot water heating systems. This ring filter seems to be used by a few brands. I wonder what the most common filter like this is on eBay.

2021-10-13 01:57:52 +0000 UTC View PostThat $2 soon adds up
My latest order from JLC with their 5 for $2 offer seems to have incurred quite a lot of extra cost for being 52 tiny PCBs per 100mm square panel. That said, there will be 36 vee-cuts per panel.
It's for a prototype string of lights based on a vintage Russian style.

You may be able to spot the fault just by looking at the picture above.

A random project inspired by a theatre friend who enquired about the technical options for achieving this effect.
https://www.youtube.com/watch?v=8hWQbQJMf5s
I think heavier petals and a softer wax will improve the effect.
