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.

Installing an Arduino Bootloader

December 4, 2013

This tutorial will teach you what a bootloader is and why you would need to install or reinstall it. We will also go over the process of burning a bootloader by flashing a hex file to an Arduino microcontroller.

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.
  • Also, while it doesn’t break out extra pins it does break out the UART, SPI, and I2C pins. Once you pick your protocol the other 2 are free pins to use for the most part. Since the code is open source you should be able to modify it to use those pins for whatever you want.

  • If the ATMega328 is running at 3.3V anything above that is technically out of spec and can cause harm. But I think the bigger issue is that the LCD needs to be powered at 3.3V. In other words use voltages above 3.3V at your own risk.

  • Good point. Also keep in mind that the questions for the Technician test changed at the end of June, so make sure the test questions you have are the current version.

  • I think the comment was more directed at the fact that Canadian Bacon and Ham seem to be the same thing (at least by what is sold under those names in the US).

  • Not really. The only connection points are the edge connector on the board and it would probably be more trouble that it is worth to try to solder wires to it to connect to the Uno. Fo the Uno I recommend the Joystick Shield Kit or just getting the Wireless Joystick Kit which has a Arduino compatible microcontroller on the board already.

  • We don’t usually do mechanical drawings, partly because everyone seems to need something different measured. But also because we do include the board files. Check out the board files in Eagle and use the dimension tool. It will measure any length, angle or radius on the board you want

  • Wow, that brings back memories. Many years ago Chris actually did just that

  • We actually retired this about 6 years ago. Depending on what you are tring to do check out the Raspberry Pi Camera which connects to the Raspberry Pi or Pi Zero pretty easily, the CMOS Camera Module which has an RCA output or the OpenMV M7 Camera which does a lot of processing on board. If none of those work check out our Imaging section.

  • While we do have boxes that size, using those boxes would increase the inventory space as well as shipping costs for most customers. If you are looking for these specifically for your camp let your sales rep know and we should be able to work with you to find a solution.

  • Anything is sewable if you try hard enough. The battery connector and the USB connector are specific and so not really sewable. The power terminals are not designed for conductive thread, but with a thin enough needle you might be able to sew to it. On the other hand with the pins being so close together I’d worry about shorting. You may be better off soldering a piece of wire to each pad, pulling it off to the side and coiling the end (unstripped) and sewing conductive thread to that.
