<div dir="auto">I have two Lindgren RF anechoic chambers with power filters and I think a USB filter dating back to the original slow USB. The larger one is about the size of the pallet it's on, square, and crushed the plastic pallet with its weight. I would contribute that one to the project if we can find a place where it would be accessible, and can truck it from Berkeley Warehouse. There is a forklift at the warehouse to put it on a truck, it's definitely going to need one to take it off. <div dir="auto"><br></div><div dir="auto">Thanks</div><div dir="auto"><br></div><div dir="auto">Bruce</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Aug 4, 2020, 6:53 PM Michelle Thompson via Ground-Station <ground-station@lists.openresearch.institute> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Resources are caught up.

There are resources available for prototyping. This report outlines some of them. <br><br>Video report here: <br><a href="https://youtu.be/2omYVVKAnhs" target="_blank" rel="noreferrer">https://youtu.be/2omYVVKAnhs</a><br><br>Transcript:<br>Here's a walk through of our mechanical fabrication capabilities in San Diego. If you have shop capabilities that you can offer for the Phase 4 project, then please file either an issue or a pull request (or write me) and let's add to the list below!<br><br>Link to document in GitHub is: <a href="https://github.com/phase4ground/documents/blob/master/Management/Weekly_Engineering_Reports/20200803_Phase4_weekly_report.txt" target="_blank" rel="noreferrer">https://github.com/phase4ground/documents/blob/master/Management/Weekly_Engineering_Reports/20200803_Phase4_weekly_report.txt</a><br><br>1) Voltera V-one circuit printer. <a href="https://www.voltera.io/product/specs" target="_blank" rel="noreferrer">https://www.voltera.io/product/specs</a><br><br>This can handle ordinary PCB material up to 3mm thick but can also do flexible circuits on material like Kapton. <br><br>0.2mm minimum trace width, 0402 minimum passive size, and 128mm by 116mm print area. <br><br>It can print, cure, and solder. It can also drill but I do not have that attachment. <br><br>2) Ultimaker 2 that has been upgraded to a 2+. We have done several microwave feeds and antenna designs including elliptical taper 10GHz horns, dual band feeds, helical structures, and more.<br><br>We metallize using conductive paint and the results have been very good. <br><br>Resolution of this printer setup is 0.02mm, which is good enough for 120GHz multi-reflector systems and beyond. <br><br>3) Wood shop with metal brake, grinding wheel, and drill press. <br><br>4) For textiles and embroidery, we have a Pfaff creative vision with embroidery deck and all the hoops. We also have a serger. <br><br>5) Multi-purpose machine, air compressors, and a 1929 South Bend Lathe. <br><br>6) This Tormach PCNC 440 is a small, light duty 3-axis CNC milling machine capable of working to accuracies of about a thousandth of an inch (a couple hundredths of a millimeter) within a work envelope of about 6 by 10 inches (150 by 250 millimeters). We have a reasonably complete set of ordinary tooling and work holding accessories for it. We are certainly not expert machinists, but with these tools we can make prototype runs of a wide variety of parts in materials like plastic, aluminum, and steel. Not every shape is easy or even possible to make with a 3-axis mill, but for most designs we can make a part that will work.<br><br>7) We have access to the large laser cutter at <a href="http://colab.org" target="_blank" rel="noreferrer">colab.org</a>. Use of the machine is free for non-commercial work. <br><br>As we enter into a stage where we will be doing more mechanical design, these are the resources that are immediately available for early prototypes. <br><br>Thanks everyone! <br><br>More soon, <br><br>-Michelle W5NYV</div></div></div></div></div></div></div></div></div></div>
