MTROB

Let me guess, 1114 or 2056?

Hoping for a water game this year! I graduated last year, but I am part of my university's Ri3D team for this year's game. We have a large group of FIRST alumni at the school who will be working on creating two different robots. The entire 72 hours will be livestreamed, to show the process, from designing to building. I spent more time doing VEX than FRC, but I feel FRC was much more interesting and applied. I would highly reccomend it to anyone who has the opportunity to participate.

As suggested above the best solution is to find a backpack that will accommodate your equipment, then add a camera insert. I climb, mountain bike, and ski, and wanted a backpack that would allow me to bring my camera and tripod with me. I ended up with a deuter freerider pro (http://www.deuter.com/DE/en/winter/freerider-pro-30-3303417.html0) and an evoc camera insert (http://www.evocsports.com/products/bags/cb-12l). I found that bags specifically marketed for photography did not suit my needs or where not made well. No ski straps, ice axe straps, helmet carrier, or room for an avalanche shovel/kit. I also really wanted back panel access to my camera gear. Although it is awkward to get to while climbing, it makes access to all my gear easier for other sports. For tripods, I suggest finding a backpack that will allow the tripod to be mounted centre. Unless you can counter balance with another piece of equipment, the offset weight of a tripod mounted on the side makes it hard to balance while doing activities. On the freerider pro, there are two straps on the backpack that allow for my tripod to be centre mounted. If helpful I can send some photos of my setup with gear attached.

I recently picked up the new Canon 5D Mk iv with the c-log upgrade. Before purchasing the camera I was in the same boat, the Sony A7R ii was very attractive. However, I was already invested too much in Canon class for the switch to make sense. Either brand is going to allow you to create excellent photos and videos. If you are familiar with Canon bodies, and invested in the glass like I was, it might make sense to stick with Canon. But, if there is a certain feature you need that is only available on Sony, such as zebras or focus peaking, it might be beneficial to switch. There are pros and cons to each brand, but in my opinion the 5D with the c-log upgrade is comparable to the A7R ii, other than the fact one is a DSLR and the other mirrorless. I upgraded from a 70D and in the few days I have had with the 5D I have seen a massive improvements in my photos. In the end, you will be able to capture great quality images and videos with either brand. It comes down to personal preferences, and if you are already invested in an ecosystem.

Concussions occur when the brain hits the side of the skull. This means force to any part of the body which transfers the energy to the head/neck, can cause a concussion. A severe concussion can be caused by minimal amount of force, especially if there is past head injury history. Slalom skiers recently have had to change helmet specifications because of repeated pounding of gates (the objects they ski around) on the helmets. The pounding gradually broke the material of the helmet down, and slalom skiers were ending up with concussions. Likely if Hirscher had been hit anywhere near the head he would have a concussion, which is a severe injury. Its important to remember these skiers are racing on ice. The snow is injected with water before the race occurs to level the playing field (Make sure the conditions are the same for each skier). This means the snow is not soft and impact absorbent like normal, it hurts really badly when you fall, and increases the quantity of injuries. This ice causes skiers and their technicians to sharpen the skis edges, leading to an increases risk of a "caught edge". If the drone were to have distracted Hirscher for even a small instant, you could have caught an edge and torn an ACL, or another ligament. This was the best discipline for this event to have occurred, the skiers have the slowest speed in slalom, as mentioned before 40km/h. If this were to have happened during a downhill event (Skiers reach speeds over 120km/h), the results would likely have been more catastrophic.

Easiest way would be to chroma key the subject, and "paste" them onto each scene at the same x and y coordinates.

Just as an update, and to help people who may have the same issue. The CPU and Motherboard both died. The cause is still unknown. I suspect the PSU, however the computer was unplugged without flipping the switch on the PSU, and died later the same night.

Khan Academy has a pretty extensive network of learning resources. https://www.khanacademy.org/

After unplugging everything, but leaving the core components in the case, it booted. However, the only way to boot it was to keep the CPU 8pin unplugged, and with the SeaSonic PSU. The Corsair PSU would not boot, even with the 8pin unplugged. Keep in mind it booted (Fans spun until I shut off), but did not POST as the 8pin was not plugged in. After reading about this online, it sounds like this means the motherboard is dead, or the CPU. Is there any definitive way to test this, and figure out what it is? I am open to taking it into a shop, if there is no possible way for me to find out.

Just tried a Seasonic 550w PSU that I pulled from my NAS. I hooked up the ATX and CPU cables, as well as a molex for my CPU fan. No relay sound, but it still will not boot. LED on motherboard did come on. Edit: Is it possible to use a multimeter to test the PSU?

It will take me a while to get one... Is there anything I can try in the meantime?

How? It worked last night, and now does not.

I just went to turn on my PC, and it would not start, from both the case buttons and the built in motherboard ones. The PSU (I am assuming, sounds like it comes from it) makes a clicking noise, exactly like a large relay would make, and does not turn on. The fans don't spin at all. The motherboard LEDs are on, and from what I have been reading this means nothing, as they are on another circuit. Nothing has been changed since last year, same hardware, same wall socket, and power cord. Although two days ago the computer was moved for a hour or two, then put back in the same place (Was not dropped or treated roughly). However it was working great last night after the move and I played some CS, and did some video editing. What I have tried so far: PSU paper clip test - Fan on PSU was spinning Unplugging and re-plugging CPU connector and 24pin ATX - Still does not work Different Socket - Does not work Because it was working last night I have no idea what is wrong. It shutdown fine, and was not slow. Any suggestions would be greatly appreciated. *Edit: Just remembered, the last computer this PSU was used in had troubles shutting down. It was solved by jumping the RTC (I believe). Specs: Asus X99-A i7 5820K (No oc) GTX 670 Corsair HX1000 (Overkill I know) Thanks for any help you can provide.

I just picked up a Zowie FK1 and it has been amazing. My old mouse was the corsair M95, which I found way too heavy. I had looked into the Final Mouse, however did not believe the build quality was very high. I primarily play FPS games such as CSGO and BF3. The FK1 has an Avago 3310 sensor (optical), with no acceleration. It does not need any drivers, and has a DPI adjustment button on the bottom of the mouse.

Like others have mentioned before, the computers themselves will not help students achieve higher grades, but they allow the students to have a higher learning ceiling. Thus the students who take advantage of the computers for learning purposes will be the ones with the highest grades. At my school, the better part of our day is spent on our computers. We use Google Drive for almost all of our assignments, which allows the teachers to give us feedback almost instantaneously. Subjects such as English or Socials (History), are completely done on a computer. However subjects such as math or science, while not using a computer specifically, incorporate some sort of technology into the class, while still relying on the old school methods of teaching. For example, some of the technology we use is the Vex Robotics system which helps illustrate some physics concepts. We also have a class called "electronics", which during the first part of the year focuses on competing in Vex Robotics, then progresses to a more self directed learning of electronics, be it programming or circuitry. However going back to the classes we use computers for, they enable us to do more through research, and to delve into current world issues/news, during our classes. The computers also allow the students to do more self directed learning, or to start the learning themselves and only use the teacher when needed. The idea behind this, is we learn the method of learning that works best for us, and to become more independent students. This greatly helps prepare the students for university where you must take control of your own learning, and where the teacher is not going to "spoon-feed" you. The computers, specifically Google Drive, allow for the teachers to focus more on the individuals in their class, as you can see them working in real time, and provide feedback. While the computers may not necessarily be doing the teaching, they are providing new tools, and resources for teachers to use. Brute-forcing the computers into the schools systems, is not the solution. Like others have said, a overhaul of the school system is needed, and it needs to focus more on the individual, and preparing them for life after school, where they must become independent. Technology should be used as an aid for learning, and teaching.
