When you see this book on amazon you think, oh that looks like a nice little book. It is nice but at 75mm thick it certainly isn't little.
It finally emerged! This is the chrysalis from 7 months ago (see www.flickr.com/photos/202848553@N08/54741088611/) that has been on my windowsill since then. I wasn't sure if it was still alive but the Sun has been pretty warm this last week and I noticed the colour changing and a couple of wiggles, so I set up my Raspberry Pi based timelapse camera setup - and just in time, it emerged the following morning!
The photos were taken every 2 seconds and the video frame rate is 30 frames per second, so every second of video is 1 minute in real life. The timelapse runs from 1104h to 1242h on 18/3/26, when it flew from the petri dish to the window. I opened the window and it hung around for a couple of hours before eventually flying off.
Although it benefitted from not having any predators, I'm not sure I did it a great favour, as none of the other wild chrysalises have emerged, so it is alone for the time being. But there are plenty of flowers around to give it some nectar, so hopefully it will be OK.

A flexible mount for the Raspberry Pi Camera module or others uses a camera T-ring as a caged nut to couple to most 42mm T-thread eyepiece or axial port adapters.
Prime focus astrophotobraphy adatper with Raspberry Pi Camera module mounted on a Raspberry Pi computer. 1/2” tape to block extranious light is removed to show the camera module mounting. Standoffs are chosen to place the imaging chip as close to being parfocal with the eyepice as possible to make image focusing convenient.
My first Raspberry Pi prime focus shot with the Questar. Streaming to VLC helped me get a reasonable focus.

Jupiter and it's closest moons on Oct 8, 2013 6:30am CDT. Taken with the Raspberry Pi camera module and a Questar 3.5. A dozen frames were wavelet sharpened and noise reduced with a little color saturation enhancement.
Raspberry Pi interface to Hope RFM12B 433/868/915 MHz radio module. An Atmel ATmega328 is used to communicate with the radio module over SPI, and to handle the interrupts. The ATmega328 communicates with the Raspberry Pi's UART (/dev/ttyAMA0). The board also contains a two-channel Atmel ISP programmer. The first channel programs the onboard ATmega328 and the second channel can program external devices. Buffering is used to protect the Raspberry Pi and allow extermal microcontrollers operating at 5V to be programmed safely..

Yes, that seems OK need keep an eye on GPU and power supply temp'
Now to test these other old screens.

Phil's Rasberry Pi wired up to my CRT widescreen TV via the yellow phono plug (RCA connector). I got the TV from FreeCycle a couple of years ago. Also in the photo is a Personal Computer World from 1979 and a fine old Mac G3.

~2.8 A @ 5 VDC with full iperf load
Each unit was 0.4 A (400 mA) @ 5 VDC
iMeter says 30 W AC, so I'm assuming 15 W power supply overhead (ick!)
In the process of being unboxed: my Raspberry Pi ARM-based "nanocomputer". Despite the photos, videos and articles talking about a "credit card-sized" machine, I was still surprised by just how tiny the Raspberry Pi is - the board really is about the size of a bank card, and the "block" on the right-hand side (see note) is the two USB ports. Incredible.
