Along with spare wood to help you downstairs, and a seemingly endless supply of 3D print materials, our electrical equipment lying behind the front desk can be found here at this. The hive is looking to create comprehensive inventory list soon. At any timeyou can come into the space and ask a PI at the front deskIf we don'have a specific component, be sure to try Senior Design on the third floor of Van Leer.

 ==== The Front Desk ==== ==== The Front Desk ====
 {{:hive_front_desk.jpg?nolink&300 |}}When you enter the Hive through the main entrance on the second floor, you'll see the front desk on your left. Be sure to sign in! The front desk is a place to ask questions, find information, check in for workshops, and learn about the Hive. If you have a question and don't know who to ask, the front desk is a great place to start. If the PIs there can't answer your question, they can either direct you to another resource or send a message to other PIs. If a room you need access to is locked, visit the front desk, and a PI can unlock and staff a room for you. {{:hive_front_desk.jpg?nolink&300 |}}When you enter the Hive through the main entrance on the second floor, you'll see the front desk on your left.

-You can also check out equipment (for free!) at the front desk, including Raspberry Pis, motors, Beaglebones, solder practice kits, USB cables, and several types of Arduinos. The loan period is two weeks, and can be renewed at the end of the time period. Other supplies, including circuit components, electrical wire, and solder, can be found near the workstations.+You can also check out equipment (for free!) at the front desk, including Raspberry Pis, motors, breakout boards, solder practice kits, USB cables, and several types of Arduinos in exchange for your buzzcard in the spaceWe no longer check out inventory outside the space. Other supplies, including circuit components, electrical wire, and solder, can be found near the workstations.
  
 +There are also lockers available for checkout at the front desk. If you have a big project, or don't want to carry a project back home each day then you may want to consider getting a locker. A PI at the front desk can get you a locker and a combination lock for it. If you forget your combination, we can look it up for you at the front desk too.

It links to their SOP! Printing at the hive is free, and is located in the Semi clean room. You can walk down and find a PI if you have something you would like to print. We only accept STL files and no gcode files since the PI's need to check each print. The printing system works by queue, and each printer may have a different queue. If you're not sure which printer you want to use, ask a PI! In addition to written and guided SOP's, we have a video series here that you can look at if you're a more visual learner. The videos are quick but may not be as informative: [[https://youtube.com/playlist?list=PLaHV-4SxpcHyglqhxBZvGin9r8XcTmYts&si=O4Soo1uygSNvHyco|3D Printing Video Series]]

 ==== Laser Cutting ===== ==== Laser Cutting =====
  
-{{:laser_cutter.jpg?nolink&400 |}}We have two laser cutters made by Universal Laser Systems Inc., which are located in the production studio on the first floor of the IDC. You can see them through the outside windows at the IDC's ground entrance. Our laser cutters can cut a variety of materials, including wood, acrylic, paper, and cardboard. They are also capable of engraving most materials, such as metalphone cases, and the examples already listed. If you would like to learn how to use the laser cutter, ask a PI to show you. If you already know how to use the laser cutter, stop by the IDC during open hours to use it. Remember that it may be different than the one you're used to, so don't hesitate to ask if you have any questions. +{{:laser_cutter.jpg?nolink&400 |}}We have two laser cutters made by Universal Laser Systems Inc., which are located in the production studio on the first floor of the IDC.

 +Recently, we have acquired a new laser cutter called the Fablight 4500. This laser cutter is a noncontinuous fiber laser capable of cutting through quarter inch steel very quickly. It was obtained to replace the plasma cutter. The cuts are cleaner and can also engrave various metals such as mild/stainless steel, anodized/not anodized aluminum, brass, and copper. The fiber laser cutter is very easy to use and instructions and more information can be found here: [[Fablight|Fablight Page]]

 +** The electroplater is no longer officially supported by The Hive. ** It still exists, and you can still use it (after the training sequence), but we can't guarantee quality to our standards as longer, given the maintenance requirements and the user base. To make vias in our no-plating process, make any vias as 1mm-diameter holes (excluding the annular ring), and then solder in a standard header pin.

 +There's no such thing as a 'best' microcontroller. It all depends on what you want to do. Therefore, depending on your needs, one microcontroller might be more appropriate. For example, the fastest chips tend to use more power than the slowest ones. The boards with the most I/O pins are bigger (and usually cost more) than ones with fewer features. Below is a list of aspects to consider when choosing a microcontroller. For more information, click [[selection-guide|Here]]
