Similarly to the other interviews that we did it was very fun to get to look behind the scenes of how the news is made. The people at Nova were great to work with. They let us take the interview in the direction we were interested in, and did not try to spin the narrative at all. https://josephscottcampbell.com/posts/week-review-10-5-23/ Thu, 05 Oct 2023 12:42:28 -0400 https://josephscottcampbell.com/posts/week-review-10-5-23/ Antivirus Research I had COVID for part of the week, so I could not work in the shop. During that time, I tested how Windows Defender detects RATs. I researched how Windows Defender detects RATs last year when I made one that uses Websockets for C2. I noticed that Windows would detect the malware once dialed out to my server. To test if dialing out was triggering Antivirus, I made a very similar RAT, but instead of using my server for C2, I used Discord. https://josephscottcampbell.com/posts/week-review-9-29-23/ Thu, 28 Sep 2023 11:41:13 -0400 https://josephscottcampbell.com/posts/week-review-9-29-23/ Continued Work on Battery Holder While I was waiting for the radios to come in I made the cylindrical battery holder in CAD. Later in the week Ben Wirz cleaned up the model. The limit for voltage on non-ROV devices in the MATE ROV competition in 12 volts, so we are putting 8 AA batteries in it (8*1.5=12). Testing Radios The replacement RFM69HCW radios came in from Adafruit. We bought the 433MHz Spring Antenna with them. https://josephscottcampbell.com/posts/week-review-9-22-23/ Thu, 21 Sep 2023 12:48:51 -0400 https://josephscottcampbell.com/posts/week-review-9-22-23/ Continued Work on Communication On Monday I started work by testing my last theory about why the packet radios might be acting up. I put them in 443 MHz mode and fashioned an antenna with the proper length for 433MHz. When I did a range test I found that it was able to go much farther and much more reliably, but it was not reliable enough to be used in the float. https://josephscottcampbell.com/posts/week-review-9-15-23/ Thu, 14 Sep 2023 12:01:01 -0400 https://josephscottcampbell.com/posts/week-review-9-15-23/ Float For most of this week I focused on the vertical profiling float. I started off by setting some long term goals by writing a timeline and outline for the float this year. The project timeline should have a working float that we can test for reliability by the end of 2023. The goals for September are: Choose communication technology Choose easily available motor Have CAD model of modular base Having working example “ping, pong” radio code Get a new bigger tube Radio Selection The first goal was choosing a communication technology.
