A walk-through of building what turned out to be a complicated prop.

We all know that women are not only a minority in technical fields, but are often not encouraged to go into such fields. Here are a few ways to encourage and support the girls/women in our lives who are interested in technical fields.

This tutorial will teach you what a bootloader is, why you would need to install/reinstall it, and go over the process of doing so.

How to Use a Breadboard

May 14, 2013

Welcome to the wonderful world of breadboards. Here we will learn what a breadboard is and how to use one to build your very first circuit.
  • A large part of this was time. I’m not a lighting person, they have a designer, I just get to run the cues. In other words, I don’t know anything about the DMX protocol and this would have entailed me learning it. Also, as far as I know that would still have involved plugging this into a DMX cable and we wanted it wireless. Very likely to be possible, but with 8 hours of work a day, 6-8 hours of rehearsal and programming the lights, and an hour or so commute time really was the main issue. Besides, I still ran the controller from the lighting booth. Those backstage were only responsible for double checking it was on and bringing out the entire prop.

  • Check out this blog post from a few weeks ago. It is all about all the shipping stuff necessary for lithium batteries.

  • Arduino 1.6.0 uses a different file structure than 1.0.x, we are still in the process of updating things. Try using 1.0.6 or email techsupport@sparkfun.com and they should be able to help you get it working in 1.6.0.

  • box making link

  • Definitely not a firewire port. The Uno has a USB port (B type, same as most printers), and a barrel jack connector if you want to power it that way. Otherwise just headers to connect to the pins.

  • Don’t always just go buy reviews. Especially for something this simple people rarely take the time to write a review saying “It works”. We’ve sold thousands of these and I see 2 complaints, that’s actually a pretty good record. As for the US plug, remember we are a US company and a large percentage of our customers are in the US. Every time we try carrying something with a different connector we end up discontinuing it because it doesn’t sell. These are so common now a days that people aren’t going to pay the international shipping fees to get a power supply when they can find one at their local store much easier.

  • Some of our more basic and older components don’t have them. If you ever come across something that needs a datasheet please email techsupport@sparkfun.com and they should be able to find you one and get it posted.

  • No, that would basically be charging a double cell battery. Your best bet is to get 2 chargers (or be patient and swap them out).

  • For clarification, this is an issue (or non-issue) that comes into techsupport a lot. With headers unsoldered a shield will sit on the Arduino headers and make contact with the USB and power jack connectors. People often stop here and say it doesn’t fit. If you solder the stackable headers on it actually lifts the shield up about 1/8" allowing the board to clear the connectors. All Arduino shields have the same footprint (with a few exceptions) and so this applies to all shields. Rest assured all of our shields will fit just fine on an Uno with the stackable headers installed. Also, never Dremel or cut your board unless you know what you are doing. In many cases there are traces on the board you might end up cutting which will destroy the functionality of the board.

  • Check out the Redbot SIK it uses these encoders and basically the same motors (I believe they are straight and not right angle). assembly and code
