USBconnector

by elektor.com:

BreadBoardManiac have been making some cool prototyping boards and accessories like their thin, double-sided, BiscuitBoard and CakeBoard that can be physically mounted onto the LEGO brick system, they even produce a special breadboard made of wood! Along with the accessories is a wire stripping gauge that allows you to accurately bend wire interconnects and cut them to the correct length so that they all line up neat and tidy, flush with the surface of the solderless prototyping board. The finished wiring looks like a work of modern art rather than the messy rats nest effect that you normally get with flying leads. You have probably already worked out that these people are passionate about breadboarding.

Watch signals propagate through basic digital circuits. Emulate any two-input logic gate using just one rLogic board and one jumper. To order rLogic+, the breadboard compatible variant, simply order normal rLogic. When the survey is sent out you will indicate which you would like.

rLogic is a basic breakout board for the Fairchild Semiconductor TinyLogic® series of Configurable Logic Gates, with an LED for watching signals and cleverly arranged header pins for simple conversion from gate to gate. Different from programmable logic, configurable logic is manually changed through rewiring using a simple shunt (AKA, a jumper), allowing you to easily and quickly morph a single pinkie sized board into any basic logic function you might need. rLogic requires no prior knowledge, but if knowledgeable of basic digital circuitry then you may jump right in with creating. If not, then a few minutes with rLogic boards will begin to teach you the basics of digital electronics.

An all-in-one breadboard with Oscilloscope, Spectral Display, Function Generator, and Power Supply.

We are excited to bring a low-cost audio range electronics development board to classrooms, labs, small businesses, and techno-geeks everywhere. This idea has been bouncing around in our family for many years and now the technology has caught up to make it a reality at a price that schools and individuals can afford. We have paired a traditional prototype board (or breadboard) with an electronics suite so that the experimenter does not have to purchase the expensive electronics test equipment needed during development. It is everything we wish we had when we were learning about circuits on a breadboard.

diy-prototyping-board-a-simple-application

by Electro-Labs:

Prototyping is a useful and powerful method in electronics which lets us analyze a circuit before using it in a system or turning it into a product. In this process we may need a single supply or multiple supplies to power the circuit depending on the type of the application. For example, an op-amp circuit may need a symmetrical supply such as +12V and -12V or a logic circuit may require both 5V and 3.3V at the same time. Some applications may need three or more. This means we should have a bench supply with multiple outputs or multiple bench supplies in the environment. This may not be always possible. This DIY Prototyping Board is designed to provide all the most used supply voltages that a designer will need during prototyping a circuit. The switching power supplies on the board output 3.3V, 5V, 12V and -12V rated at 1A independently. In addition those there are two precise voltage references at 5V and 2.5V provided especially for op-amp based applications.

Audigi @ instructables.com show us how to use an Arduino board to burn Arduino bootloader to mcus on a breadboard. He writes:

Connect Arduino Uno board to your computer. Start Arduino program and from examples choose “ArduinoISP” sketch and upload it to “Arduino Uno” board. Please make sure you select the correct board name and serial port. Now this board is ready to program new Atmega-328 chips on the breadboard as shown in the next step.

What is the actual capacitance of typical breadboard contacts?

It’s not in the datasheet, so Dave decides to measure it. It is well know that breadboards are not suitable for high frequency work due to the stray capacitance between contacts, but how bad is it really?

If you’re like me, after I got my Arduino and performed a final programming on my first chip, I wanted to pull it off my Arduino Duemilanove and put it on my own circuit. This would also free up my Arduino for future projects.

The problem was that I’m such an electronics newbie that I didn’t know where to start. After reading through many web pages and forums, I was able to put together this Instructable. I wanted to have the information I learned all in one place, and easy to follow.

The BZB Breadboard eliminates the middle man, no reason for a separate card, the Arduino compatible micro-controller is built right in, in one piece, that makes it End User Friendly and New User Easy. It is the right tool for Arduino Power Users, Educators and New Experimenters alike.

Are you looking for a portable breadboard power supply with a selectable voltage? Also thinking about how long the batteries will last? This project utilizes one or two AA/AAA batteries to generate a preselected voltage of 5V or 3.3V, and  squeezes the batteries untill they have almost no power at all.  AASaver is based on the Microchip MCP1640 boost converter. [via]

When your electronic devices report that the batteries are ‘dead’ and need to be replaced, do you ever feel frustrated that there is often still a lot of juice in them? Don’t throw away the batteries yet! You can use the remaining energy to do a lot of things, such as powering LED flashlights. This is possible by using a boost converter, which can bump the low battery voltage to a higher voltage, enough to light up LEDs or even power breadboard circuits.

A little over a year ago, I started playing around with the newly available AVR ATTiny4313. It’s a neat little chip, and you can have a lot of fun with it. However, I soon got tired of wiring up programming headers, power supplies and all the other stuff you need to get up and running. I also grew wary of all this support circuitry taking up significant breadboard real estate.

To eliminate all that hassle, I created the BB313. It’s got all the stuff you need (programming header, regulated 5V power, etc.) wrapped up in a nice little package, and it plugs in on the edge of the breadboard so you have lots of space for other stuff. I also added an 6-pin connector for an FTDI cable or adapter.

I originally designed it for myself, but I figured other people might like it too, so I’m releasing it open-source CC-BY-SA 3.0) so you can make your own.

All the details and source files are at the project page. If you find it useful, please let me know!
