Arduino Uno's

The Arduino Uno is a basic prototyping board you can use to make simple electronics. It's one of the best ways you can get started with electronics and coding. Basically you can code the board to give specific outputs, based on inputs on specific pins. It's one of the most well documented microcontrollers, so if you're looking for something specific, the chance is someone has tried to do it already and google will be your best friend. If you're looking to get started with Arduino from little to no basic coding knowledge, here is a tutorial on how to do it that goes through some of the basics and leaves room to expand: https://docs.google.com/document/d/1WBJcONsipZW8AqFeg47Jnr9jpsoVE378khvsaSx-Pe4/edit?usp=sharing


Oscilloscopes


Soldering Irons

If you'd like to learn how to solder, check out the beginners guide here: https://www.makerspaces.com/how-to-solder/. This section will focus on information about the soldering irons we have.

Our electronics benches are equipped with Weller WES51 soldering stations connected to Weller soldering irons. Our soldering station has a variable temperature, the number on the dial is 1/10th of the actual temperature of the iron in Fahrenheit. For example, when soldering through hole components you'll want to set the dial to 70 which represents 700 degrees Fahrenheit.

Make sure you always put down butcher paper before you start soldering, solder can easily ruin our nice wooden tables



Desoldering Tool

Our desoldering tool is a Hakko FM-2024. The purpose of this tool, as you can imagine, is to remove solder.

You'll use the end of the tool to heat up the joint, and pull the trigger when the solder is liquefied to suck it into the gun. This deposits the solder into the insulated orange canister you'll see at the top of the gun.

This chamber can easily be replaced when full, and can be checked by simply pulling the yellow guard back towards the gun. The guard will click into place, and you can remove the orange canister. When you replace the canister into the gun, simply hit the yellow button on the top of the gun to release the spring.

You'll need to adjust the temperature of the Desoldering Tool as you would the soldering iron, since the goal of the tool is to liquefy the solder.

SMD Rework Station

The SMD Rework station is a tool we use to solder and desolder Surface Mount Devices. SMD's are components that are soldered directly to tabs on circuit boards, rather than having leads that go through the circuit board. These components often take up less space on the circuit board, with the trade-off that they are rather tricky to solder.

The SMD Rework station applies heat to solder joints by blowing hot air onto them. This allows you to hit multiple joints at the same time, and makes it much easier to work with SMD components.
