I've wanted to do something like this for a long time: Switching stuff in and out easily.

 

This is Joe Davissons Easy Drive into my Green Ringer. Currently, there's way too much gain but it's a start.

Tiny breadboard with microcontroller.

Here's a hefty wirey breadboard-based bit of fiddling toward my next nixie clock. I haven't finished the first one yet, nor have I given up on it - its enclosure is second in line behind the bookcase I'm making in wood shop. Once that's done the clock is pretty much finished (minor software tinkering still remains).

 

For the next clock I'm planning a rather different sort of design, so I'm testing out the parts I haven't tried before. I'm going to try multiplexing the display - i.e., building it so that only two tubes are lit at a time instead of all of them, but switch between them rapidly enough that persistence of vision makes it look like they're all simultaneously lit. This has the advantage of needing fewer components on the circuit board. This new clock will use 6 tubes (hours / minutes / seconds) so a multiplexed approach saves a lot of board space.

 

On the left here is a Soviet IN-12A tube. Its numbers show through the top of the tube, so they're not visible from this angle. On the right, a National NL-5440A. Both of these are rigid-pin, non-breadboardable tubes, so I soldered wires onto a couple of sockets and voila. Works great, even if the tubes with their sockets and wires end up looking like those creepy baby-harvesting robots in The Matrix. (On update, Mrs. W. points out that they resemble Kodos and Kang from The Simpsons, which is a much less chilling [if more slobbery] image.)

 

I've had some NL-5440As for a long time - some 7 years or so. I've never gotten around to lighting one up until today. They're very handsome tubes.

I've heard that you shouldn't stack things in lower drawers, but this drawer is too deep to permit only one layer of shallow items.

 

This drawer currently contains the most-used baking items, all in one place. It's wonderful and I think I'm going to keep this grouping concept wherever the ingredients and gear end up being stored. Great to look into it and pull out baking power, flour, etc. etc. etc. all at once and it's high enough that it's no strain to reload the drawer from the countertop after washing down the breadboard and pushing it in. Attachments for the mixer are in here as well as rollling pin, mixing bowls, and hand mixers.

 

Above this area on the countertop are mixer, blender, and food processor. Rubber spatulas and large spoons are in the canisters on countertop to left of this space. Works well.

A simpler, arguably "greener" version of my Big Stripey Board, now with domestic hardwoods only: walnut, maple, and cherry. Size is a little under 12" x 16", and about an inch thick, not counting the little rubber feet.

Digilent Analog Discovery 2 is a USB oscilloscope and multi-function instrument that allows users to measure, visualize, generate, record, and control mixed-signal circuits of all kinds. Developed in conjunction with Analog Devices and supported by Xilinx University Program, Analog Discovery 2 is small enough to fit in your pocket, but powerful enough to replace a stack of lab equipment, providing engineering students, hobbyists, and electronics enthusiasts the freedom to work with analog and digital circuits in virtually any environment, in or out of the lab.

Part# 410-373

This cutting board measures 17" x 10" x 3/4". Made with wanut, maple, and oak. Hand-rubbed oil finish is food-safe.

This tiny 5V breadboard power supply is made using a voltage regulator, two 1µF capacitors, a resistor+LED and a power switch. It has a 9v battery clip for input, and the voltage regulator's pins are used to connect it to the breadboard. It's basically a voltage regulator with a circuit soldered to the legs!

 

It's providing a nice 4.96V, which is close enough I guess.

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.

The standalone Arduino circuit (almost) exactly as it will be in its final form. The only difference is the LED, present here for troubleshooting.

This is a little power supply I built for testing a couple of types of vacuum-fluorescent display (VFD) tubes. Most of what's on this little board is the same as the power supply that is breadboarded in the blurry background of that shot.

 

I decided to use this project as an opportunity to learn how to design my own switchmode power supplies (SMPSes). Briefly, SMPSes convert one DC voltage to a different one. They're useful for things like nixie tubes, which need about 180 volts to work, while typical "wall wart" power supplies usually only deliver 3-12 volts or so. A step-up or boost SMPS can convert that low input voltage to a higher one, with the costs being some energy loss in the conversion and a lower output current. VFD tubes need less voltage than nixies - the ones I own need from 25-70 volts or so - so they're another candidate for a boost SMPS. This relatively low and unscary voltage made a VFD supply seem like an ideal project for learning about how to design SMPSes.

 

Designed and built properly, SMPSes can be very compact and efficient. This one isn't especially compact, being about the size of a credit card and using components an inch thick or so, but that's plenty small to fit in a desk clock or similar device. This particular one will just be used for quick tests, but the same components would fit in a clock. I don't know how efficient it is. I'll test that a bit later.

 

I got this one to work tolerably well, and I may tweak it a bit to see if I can improve its performance - but it works well enough to be going along with.

 

The switch with the Italian-flag-colored wires going to it is a voltage range selector. In the left position, the circuit is tuned to emit from 19 to 40 volts, and on the right, it will kick out from 36 to 75 volts. These ranges are useful for a couple of different types of tubes I have.

 

This circuit is also the first one that I managed to diagnose and repair using my oscilloscope. The output voltage had been sort of acceptable but wandering around a bit. Using the 'scope, I found out that the long wires leading to the voltage range swicth were picking up a bunch of electrical noise and stuffing it into a critical part of the circuit. A small decoupling capacitor solved that, and now the supply works quite nicely. Yay for o-scopes, trusty guides on my Voyage of Electronics Discovery!

 

Update, 8/8/2010: I killed this circuit today by plugging it in to a 12 volt power supply. That's what I get for not documenting my circuits properly! :(

Cutting board made with cherry and "bird's eye" maple, highlighted by walnut striping. Unique features are brought out with food-safe oil finsh. Measures 16" x 9" x 3/4".

My latest Big Stripey Board, now featuring Zebrawood. I love what the zebrawood adds, I'll be doing that again for sure. Species from the outside edges are Purpleheart, Quilted Maple, Walnut, Zebrawood, then Purpleheart again, then Maple in the middle.

 

The board measures 10" x 15" by 1.25". Usual features include finger grip recesses for easy lifting, and little rubber feet to keep the wood up off the wet counter. Finished with plain old mineral oil for ultimate food safety.

for our session we worked on the story of breadboarding a project using kits donated by oomlout.co.uk, documenting them in an EDA tool (Eagel, KiCad, DesignSparkPCB or Fritzing) and uploading them to solderpad.com oshug.org/event/oshcamp

A breadboard test of a DC motor controller. It works by PWM (Pulse-Width Modulation), using a TLC3704 comparator chip to generate a variable mark/space ratio square wave. This is then fed to a HUF75337 power MOSFET. There's a 5k pot in a box to control it.

The main concept behind the initial idea it's use the OLED on a breadboard. Most of this display use flat connectors, hard or impossible to connect into a breadboard.

This is a custom TQFP socket breakout board that I made specifically for programming chips before soldering them onto the board. This helps identify bad chips.

 

I also can breadboard the entire project before I make the board to ensure the schematic is correct.
