Building version 2, six ICs down and tested. Including LM393 dual comparator and the two TS12A4514 analog switches from version 1, used to reset the integrators.
There is also now a 5V rail (on left) for powering the analog switches and the CMOS chips to be added. There won't be enough room on this breadboard for everything.
Update: This version has already been abandoned, because I forgot to include the multiplexers that "freeze" the integrators when required. Also, it's likely I will begin to use the Yamaha Y3014B floating point DAC for the integrator slope (coefficient) voltages, because they have important extra precision for small magnitudes.
You can still get these from jdr microdevices. This was the heart of the Vectrex video game system from back in the day (if you go to Video Games New York they still have one of these)

Revolutionary New USB Charging Device Set To Launch via
Crowdfunding Campaign.
Mobile devices to charge 400% faster than standard USB chargers.
Los Angeles, CA – July 7, 2015. USBeast Electronics has developed an on-the-go USB charging device that will change the way consumers charge their mobile phones, tablets, cameras and even the latest Macbook and Google Chromebooks. With the ability to utilize 2.1 amps of charging power, USBeast can charge a dead iPhone at least 6 times to a full charge without the use of a wall outlet and do so 4 times as fast.
Increased use of technology in all areas of our lives has highlighted an already nagging problem: Too many electronic devices and not enough charging capability. On site workers, outdoor enthusiasts and people living under the constant threat of a natural disaster are increasingly faced with the problem of finding adequate ways to charge their USB powered devices.
The USBeast solves that problem like no other USB charger on the market today. With millions of cordless power tools and camping accessories already sold, there’s an established mass market of people who can use their cordless tool batteries to charge their mobile devices. The USBeast utilizes many different brands and voltages of cordless tool batteries to simultaneously charge 2 mobile devices. For example, an iPhone and iPad can both go from 0% to fully charged at the same time, without the use of a wall outlet. There is no other charger on the planet with that capability.
After several prototypes, the USBeast design team has worked feverishly to approve the version which is now ready for mass production. The final USBeast design has been field tested and sold online in small quantities, receiving positive feedback from both consumers and testers alike. USBeast Electronics has a live crowd funding campaign on Kickstarter.com and pre-orders of the USBeast are now being taken! The company is also selling USBeast Brand merchandise to assist in generating the financial resources necessary to mass produce and bring the USBeast to market. When the funding goal of $15,000 is reached, USBeast Electronics will begin full scale manufacturing with the finished product proudly being made in the USA.
"We are committed to revolutionizing the way consumers charge their USB powered devices and dedicated to making this product a huge success,” says Jonathan Williams, founder of USBeast Electronics and The Artisans Studio. “We will strive to provide the best quality product and update our backers every step of the way.” Williams continues, “And provide the assurance that all USBeast orders will be shipped on time.”
This Kickstarter.com campaign will end on August 21, 2015
USBeast Electronics is on a mission to create the next generation of mobile electronic charging products for the current and next generation of mobile devices. For more information contact: or email sales@getusbeast.com.

In order to reduce the clutter and to test some new sensors, I recently got myself this ATmega32u4-based 10DOF MicroWii controller board from Flyduino. This is the top view of the PCB.
With a DAB/DAB+/FM tuner, universal iPod dock and auxiliary inputs, R2i is a complete music solution and perfect for customers seeking high quality sound in small to medium sized settings.
The enclosure of R2i is hand-crafted from materials chosen for their exceptional acoustic properties and finished in Rich Walnut veneer or Dream White and Midnight Black high gloss lacquers. These finishes combine perfectly with the cool steel panels and mesh grilles to create a tactile feel to match R2i’s elegant design. Our distinctive ‘RotoDial’ controller sits atop of the unit making operation easy and intuitive.
The look of R2i exudes style, but sonically it’s equally impressive with our custom made high-fidelity speakers and electronics providing a scale and quality of sound that simply belie the R2i’s discreet dimensions.

Having tapped off 12VDC from the monitor's own SMPSU, I parallel connect the two light strips.
One thing to note is that the backlight will remain on, even if the monitor is in stand-by.
Turn it off at the mains inlet.
