Ring of Fire
The usual cloud cover and a simple handphone camera didn’t make for the
most scientifically accurate images of the
26 December 2019 Annular Solar Eclipse,
but after pushing all the filters to 10, this snap from my window in Singpore is perhaps
more interesting for it!
I remember seeing my first solar eclipse in 1976 standing on the beach in Melbourne. The transition from full summer sunkist to an eerie dusk was exhilarating for my young mind pumped up on school projects about eclipses, pinhole cameras and the like.

LEAP now has its own feed
For a couple of years I have been using this blog to post snippets about new projects in the Little Electronics & Arduino Projects (LEAP) GitHub repo.
This was mainly a way to have a project link I could use as link bait;-) … but it was also a chore I could do without!
A little while back I revised the Jekyll static web site generator that runs over the LEAP repo and is responsible for for its accompanying site at leap.tardate.com.
Now the LEAP site renders each project nicely for the web, with social sharing support i.e. with twitter card, open graph etc. It also has an RSS feed of all the projects as they are added. To dig under the cover of how this works, see notes in the /catalog folder of the repo.
So in future, I’ll probably only post about LEAP projects on this blog if they are really really special in some way. And if you just want to follow the electronics stuff - follow leap.tardate.com instead of this blog!

LEAP#465 Mr BiJuT
Mr BiJuT is what I’m calling my freeform realisation of a simple NPN/PNP transistor testing circuit.
This is a nifty little design that I found in the Radio and Electronics Cookbook. It is one of those circuits that is the height of simplicity but is also quite tricky in it’s own way! Whether you immediately “get” how it works depends very much on how you draw the schematic;-)
As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub

LEAP#461 The Goblin
I remember lusting after an Ibanez Tube Screamer back in the day - they really were the stuff of legend. The most famous is perhaps the TS-808. After researching the original circuit and examining how it works in detail. I decided to build one with only a few modifications to the original circuit. I’m calling it The Goblin, owing to the custom stippled-green paint job I gave the 1590B enclosure.

I’m really impressed with the sound it produces. Here’s a quick soundcheck and smoke test:
