big change: switched to LP2951 power supplies for their shutdown pins.
small change: dropped unused 7805 regulator, added 1n4004 input diode, tightened everything up, dropped extra power supply enable circuity, switched to pin headers for power supply (2 for each voltage).

The switch alternates the two LEDs. It's a neat little board, although the 7pin header was added by me to make it a bit more extendable.

A new generation of cheap lightweight plastic electronic technology that does not require silicon, but which is optically transparent and can be coated onto everyday objects would transform our world.
"Working collaboratively with industry is not only satisfying in that I see aspects of my work translate into real engineered products, but it provides inspiration for new avenues of research too. Roadmapping then allows me to critically assess how I should be developing my research portfolio and engaging with industry to maximise the likelihood of productive collaboration."
—Dr Andrew Flewitt
Imagine electronically updated food labels, computers embedded in our armchairs, even contact lenses linking us directly to the Internet to bring us into the age of plastic electronics. In this video podcast Dr Andrew Flewitt and Dr Robert Phaal both from the Department of Engineering and Scott White serial entrepreneur and CEO of Pragmatic Printing talk about the creative partnership forged between different parts of the Department of Engineering and outside companies that enable the technology and research in this area to be exploited successfully.
Dirty Electronics Mute Synth custom modified by A.S.M.O. for Daniel Miller (The Normal / Mute Records).
Touch panels hardwired to pots and switches, 3 LFOs, one for each oscillator and feedback.
Low / band pass resonant filter with external voltage control input, self oscillates at full resonance.
Panel is covered in (warm) leatherette, nice!

These make up the Lamp Dimmer which is our project in the university. We got 1.00, the highest grade in this subject.
On Friday April 18, seven of us drove 100 miles east of Portland to the mouth of the Deschutes River (at the Columbia) to camp overnight and ride the 22 mile out-and-back Deschutes Rail-Trail on Saturday. This is the start of the "dry side" of Oregon, so the landscape was appropriately arid and Western-y. It was a fun ride. The trail is a bit rough, but rideable, and we managed to avoid the goathead thorns that are notorious on the southern end of the trail. The weather was mostly good with the exception of a passing shower.

This is an important professional book which has been carefully prepared by the author for many years. Electronics is arcane and abstract. But it is also an exact science of real practical importance. Whether we appreciate it or not, our lives are practically dominated by electronics, e.g., TVs, computers, smart-phones, et. al.. Applying electronic theories would bring actual, practical results which could be tested or gauged by instruments. This book on practical electronics should therefore be taken seriously. This book has been painstakingly prepared for readers who suffer from a phobia of technologies which tend to be difficult to grasp. This book is apparently the only one of its kind now which conveys important, useful electronics knowledge in a very simple, jargon-free, easily comprehended manner. In the book the author also shares some of his experiences in electronics by offering practical tips on circuit design. What are required of the reader of this book are just some patience, interest and motivation.
This title is now available at the Kindle Store.

This rat's nest is the shutter electronics, on the blue board, and the photodiode amplifier on the white board. I'm using a Raspberry Pi Pico, which I can cope with more easily than the PIC 12F675 controller specified in Frans' design. Also, at £3.60 I couldn't resist getting this device to play with. Otherwise the shutter driver electronics are exactly as his version. At the moment there is no provision for the rangefinder or flash control, it's just the shutter driver.
The main circuit is built on a Raspberry Pi Pico breadboard, which is great for prototyping. The extra lights and switches were very convenient for debugging the circuit and software. Intention: ultimately a pcb with Fritzing.
I'm developing the software using the Thonny IDE with micropython. With this I can use assembler for the PIO state machines to get precise timing. The current code is not optimal in that respect but I can see that when I start working on the flash trigger, precise synchronisation with the shutter open time will be essential. I intend to make the code and other details of the project available on my GitHub account.
