News - Expanded Options for 3D P…
about 7 months ago
I've 3D printed a replacement lid for a (commercial) Jiffy Box so that I could mount the controls for what was inside the box.
More, I took the opportunity to first print just the labels, then changed the filament colour to print the rest of the lid, with voids for where the labels and controls go. The result was a high-contrast labelled lid with perfect slots for mounting the controls.
See Thingiverse #3602308
Please advise if the board has a JTAG connector for the CPU - or better yet, Trace (ETM or other).
News - Mathematical Color Fading

I agree that each of the described colour systems are valid, both Rob's and other members'. However, if you're going to describe them as "additive" and "subtractive", then neither supplied diagram is helpful in explaining the two terms.
For "additive", the background should start as blacK (not White), then the Red, Green and Blue circles (adding/reflecting one colour), and where they overlap showing Cyan, Magenta and Yellow (adding/reflecting two colours), with the center being White (adding/reflecting all three colours).
For "subtractive", the background should start as White (reflecting all colours), then the Cyan, Magenta and Yellow circles (subtracting/absorbing one colour each), and where they overlap showing Red, Green and Blue (subtracting/absorbing two colours), with the center being blacK (subtracting/absorbing all three colours).
Note that I capitalised the relevant letters in each colour: the two most common colour systems are RGB (additive) and CMYK (subtractive).
Tutorial - Headless Raspberry Pi Setup

An often-overlooked feature of Etcher is that you can point it at the compressed (.ZIP) version of the image to flash directly, rather than having to waste time and disk space unzipping it first. It will unZIP it as part of the flashing operation!
This becomes doubly important with the non-Lite versions of the Raspberry Pi image. Those are more than 4 GB in size, so require a 64-bit unZIP program - which Etcher is...

I don't actually know, but I highly suspect that this is indeed the case. I've ordered two to find out...
No public wish lists :(
