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!

phirephly build a debounced breadboard keypad:

I’ve been getting tired of having to wire up buttons and paste in debounce code (or wire up debouncers for TTL projects) every time I want any kind of user input.

I was browsing around Maxim’s site, when I stumbled upon the MAX6816-6818 series of button debouncers. These are single, dual, and octal channel debouncers. Attached is the design files for a simple eight-button breakout board for the MAX6818 designed to be plugged into a breadboard. In addition to the eight active-low debounced outputs, the edge connector includes an active-low button-change interrupt, and an active low enable input, which can be optionally solder-jumpered on, if the button outputs don’t need to be tri-stated.

Because of their compact size, ease of use and many built-in peripherals, the 18-pin PIC16F series processors (PIC16F628A, PIC16F88, and now PIC16F1827/47) have always been my favorite microcontrollers. Many of my projects and tutorials written in this blog also use PIC16F628A and PIC16F1827 microcontrollers. As I will be using them more in the future too, I thought of making some PCB versions of my breadboard module for PIC16F628A with some modifications. I used Iteadstudio’s PCB prototyping service for this, and I would say the PCBs turned out really well for the price I paid. I used their 2 layer 5cm x 5cm service and got 10 PCBs for less than $15, including shipping to the United States.

If you happen to work with microcontrollers or other digital ICs, then you have certainly face a situation where you need urgently 8 LEDs with 8 resistors for a test or other debugging purposes. And it is this time where things get nasty: You are in a hurry because you want to see the results, connecting the LEDs is totally boring, you need also 8 resistors, not to mention the wires, and then, the LEDs themselves are thick and usually won’t fit in 8 breadboard rows… You know what i mean.

Blondihacks has developed a breadboard programming header for 8-Pin AVR microcontrollers called the Bread Head. [via]

This little guy was easy to make, and has been a real time saver when iterating on a breadboard. The trick is upside-down protoboard, and longer-than-usual headers! Read on to see how it’s built.
