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

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.
  • Not easily. Blynk requires internet access and this will not get on the internet. You can definitely make a network of these to gather data from lots of remote locations and then connect one unit to a Wifi module (or cellular module) to get things online. Unfortunately as it is this just doesn’t connect to the internet.

  • Page 8 of the datasheet says, “The RFM69HCW complies with both ETSI and FCC regulatory requirements and is available” which makes me think it is not certified but should pass certification. Also antennas play a role in FCC certification meaning they could certify it with a certain antenna but if you used a different one it would not be certified. With something like this that you have to add your own antenna which will likely have a slightly different length since you are cutting it by hand they probably just decided against it.

  • Check out the RSSI LED, in some of the 900MHz XBees the LED on this line causes problems (I don’t remember if the XSC is one of them). If so check out the solder jumper to disconnect it. If you are still having problems try emailing techsupport@sparkfun.com Edit: Sorry this board does not seem to have the jumper for RSSI, but it might still be the problem.

  • Make sure you’ve uploaded the correct bootloader as there are a few that will work on the ATmega328. Also make sure your fusebits are correct. The Arduino IDE will grab the fusebits from a file and set those when it uploads the bootloader. This is good if you are actually uploading to an Uno, etc. But if your setup is a bit different (like using the internal clock instead of an external crystal) this might cause problems. Also, if you didn’t use the Arduino IDE to upload the bootloader you might need to set the fuse bits. If you still have questions feel free to email techsupport@sparkfun.com with a summary of what file you used, how you uploaded the bootloader and a screenshot of any errors and they may have more answers for you.

  • I believe the plan is to contact original owners about getting them thermal gap filler. Check your spam folder for SparkFun emails and if you don’t see anything email customerservice@sparkfun.com and they should be able to help you out.

  • The board just drives 3 stepper motor channels. Assuming you connect it to a 3 axis gantry like the Shapeoko you can connect anything you want (Sharpie, router, laser, 3D print head, pick and place head, etc.). Check out the video for Marshall’s tiny DIY laser cutter (doesn’t cut much more than paper because of the laser he used, but it works).

  • Check out the schematic and if you need more information check out the datasheet for the chip.

  • You are correct, while the Redboard does fit in some Arduino cases it is a tad wider. The reason for this is those SMD headers which need just a little bit of room on the sides. I wish we could do both, but all SMD and a flat bottom is more important to us at the moment than exact dimension matching.

  • You’ll have to wait if you want to really find out.

  • Remember the ESP8266 does little on it’s own. You need to provide it with power, it using a battery you need to make sure it is charge, you need to provide sensors etc. You rarely end up at $2 when you are done. We definitely believe that a plain ESP8266 has it’s uses which is why we still carry them. But what about someone who just wants to start programming and learning? What about a school that doesn’t want to have to keep track of parts and have kids soldering sensors on? Now you can learn to get data to the internet and all you need to do is power the board. As for the PAYG service we’ve played with it and for someone who just wants a quick app and doesn’t know how to write there own it is a great option to start with. And if you do know how and want to write your own you can. While we worked with Blynk on this board and specifically getting the firmware to talk with it, the service itself is completely optional. In other words we’re trying to provide you with option and more options. This board isn’t for everyone just like the ESP8266 bare module isn’t for everyone.
