A new version of this pummer circuit, but with the solar cell installed. Low and behold, it worked the first time! I soldered it up, plugged it in and the LED pummed; then I aimed a flashlight at it and the pumming stopped.
See the notes on the previous photo for the rest of the details.
Watch a video of the pummer in action on YouTube!
The first test program for my TMS9918 board just displays "Hello world!" on the screen in text mode.
Here I've connected it to a Commodore 1702 composite monitor.
I'm assuming the vertical banding is caused by lots of noise and/or stray capacitance on the breadboard. Hopefully it'll disappear when the circuit is on a perfboard or PCB.

It is rare for homemade bread to be wasted, whereas a very large proportion of bought bread ends up in the dustbin because it is not valued or in any way respected.;

My nixie tube clock protoboard. It's a combination of modern technology components and 1950 technology nixie tubes. I designed the display PCB and had it fabricated. The bottom side of the PCB contains 12 SMT transistors, 12 SMT resistors and 6 thru-hole resistors. The 6 nixie tubes are controlled via a multiplexed scheme. The control and high voltage generation circuitry on the breadboard will eventually be moved to a daughter PCB.
I bought this breadboard because it was listed as working with the “Bread Board Power Supply Shield (5V/3.3V compatible)” (Product 18/37) and it was cool and clear from Iteadstudio. I was a little disappointed it does not have a proper hard backing on it. It only has double-sided tape for mounting. I also found the side power rails a bit hard to push components into. I bent a few legs trying to get them in.

A 21st century interpretation of William Penn’s “greene country towne” will appear atop the PECO Crown Lights as the first Art in the Air exhibit of 2011 opens Friday, Sept. 2.
"The Green and Growing City" was created by Timothy Wingert specifically for the PECO Crown Lights as an animation reflecting both the life and energy of the city as well as Philadelphia's leading role in making urban areas "green" and artistically integrated into their natural surroundings. This 30-second animation of nature's growth and life cycles seen on top of one of the city's prominent structures represents what William Penn's idea of a “greene country towne” is all about.
Wingert’s work will be shown alongside “Dancers” by James Simpson and “Cool Waves” by Chris McManus. All three pieces will be displayed on the Crown Lights each Friday in September from 7 p.m. to midnight.
Art in the Air is a partnership between Breadboard, a program of the University City Science Center that explores the intersection of art, science and technology, and PECO. The September artworks were selected by Breadboard and PECO.
New exhibits will be mounted in October, November and December. In January, PECO and Breadboard will select the “Best in Show” works, selecting up to three pieces featured during the four, month-long exhibits for a chance to receive a $1,000 prize from Breadboard.
“Art in the Air” was launched in 2010 during Philadelphia’s annual Welcome America Celebration, commemorating the first anniversary of the launch of PECO’s new energy efficient LED Crown Lights system. In 2010, PECO featured the works of more than 20 different artists atop the lights as part of the program.
Artists interested in submitting their work for consideration should click here or submit their work to artintheair(at)sciencecenter(dot)org. More information about the PECO Crown Lights is available at www.peco.com/crownlights.
About Breadboard:
Breadboard is a program of the University City Science Center that explores intersections between contemporary art, design, science and technology. Expanding on 30-plus years of Esther Klein Gallery programming, Breadboard's mission is to convene communities around creative applications of technology. Breadboard also manages the Esther Klein Gallery (now known as EKG) at 3600 Market Street.
We've created an easy to assemble Breadboard Based Arduino Compatible (BBAC) Micro-controller product,

This custom designed table was made to have a 40x52"long top - 1 1/2" thick - with random size planks and finished with faux breadboard ends. Rustic 1/4 Sawn White Oak / Ebony.
The matte black finished metal bases are called our "Golden Gate". Available in other finishes.
This Rustic Timber style table was made 44"wide x 72"long plus 2-18" breadboard extensions (108"L when in).
This particular table was made without the standard planks in the top but is heavily distressed and has rolling hand planing with hatchet marks - all atop the standard 2" thick Wormy Maple top.
Also shown are 6) Muskoka side chairs.
All in Wormy Maple / Frontier
The interesting part is that I mostly used the length of components legs as wires! It's time to save the most we can: even copper! ;-)
My first long soldering in my life...sorry if it's not well done.
This Mini Breadboard is a great way to prototype your small projects! With 170 tie points there's just enough room to build and test simple circuits; They're also great for breaking out DIP package ICs to jumper wires! If you run out of room, no worries, these mini breadboards can be snapped together to form larger stretches of board. It has a peel and stick adhesive backing as well as two mounting holes for M2 screws so you can anchor it down.
Available soon.
My 6809 computer can now generate color composite video!
On this breadboard is a TMS9918 Video Display Processor (used in the TI-99/4a computer, the ColecoVision, and others) and 32K of video RAM.
The TMS9918 outputs 16 color composite NTSC video at 256x192 pixels and supports up to 32 sprites. As far as video chips go it's very primitive, but not too difficult to work with.
The circuit is basically the same one used for the N8VEM Color Graphics and Sound board: n8vem-sbc.pbworks.com/browse/#view=ViewFolder¶m=C...
