content: Nice review!I have had an HP All-In-One with 23" touch-screen for several years. I have never used the touch-screen capability. Just turns out...I could see the Surface Studio as a replacement for the HP and then I could push the HP down to some kind of Linux box.

content: The price point of this occupies a weird niche spot. Not quite sure what to think of it, as someone who works in graphics (EE is just a hobby).The cost is really high, but businesses who have the sort of money for this sort of thing will just go full Cintiq (wacom's high end screen) and a dedicated tower. Cintiq's will be better for artists anyway, since these support barrel rotation, pen tilt, etc. Businesses and individuals with less money will just go for a regular Intuos, or a Huion "clone". I own one of the latter, it does the job, but doesn't have advanced pen stuff. It's also only $600 (+ the cost of the computer).So the MS Studio is fit for.... wealthy at-home professionals who are into digital art, yet don't want or need pen tilt/rotation that the Cintiq and Intuos (screenless) has? Hmmmm. If you have this much money, you'll just get a Cintiq 27QHD.Not criticizing the actual hardware. I'm sure it's great. I own a Surface Pro 2 and the quality is very high.

content: I have been out of the recording studio scene for a while, and while investigating new versions of pro tools today I heard a term that I was happy to have not heard in many many years.DONGLE!Seriously. A hardware security dongle. I thought I left those behind in the 80's. Avid in their wisdom has decided to keep this ancient concept going. To use their free 30 day trial one must purchase an iLock USB dongle for near $50 US and link it to an account. So its essentially a free trial that costs $50! I understand the need for security, but I mean come on. A 32 Byte online verified encrypted key is more than good enough for everybody else out there. Is this just a case of somebody in the dreaded audio industry trying to feel special?FAIL!!!!!

content: In a nut shell: ( low voltage applied ) x ( low power laser or infrared laser) = free electrons in spaceThey mention solar power a couple of times and that makes sense if you use infrared, but you still need to apply voltage which would defeat the purpose. So they are likely releasing the electrons from the 'low voltage' and there wouldnt be any gain. Sounds like a high tech transformer.😋

On powering them up (latest driver from the FTDI website) the produced the well known "non genuine device found" message. Contacted supplier, who apologised and sent two replacement boards - only for these to have exactly the same issue. These were from a different batch too. Contacted Gravitech to inform them of the problem, but no reply...Meanwhile I purchased a couple of genuine FT232 chips from a well known UK supplier, and soldered these in place of the fake parts on the Gravitech boards, and all is now fine. Shouldn't have to be spending my time and money working around fake chips like this when I'm buying supposedly quality items from a very well known supplier! Jus thought I'd post this as a warning to others that the fakes are out there. Almost impossible to see any difference at all in appearance between the fake parts and the real items.

I cant workout what makes them both different from each other. If anyone would look at this for me and be able to tell me i would greatly appreciate it! i have had a look at data sheets but its confusing to me.At the minute im using the TPS2514DBVR ic on my PCB board that was purchased from china. iIT recognize my windows phone and a (I-phone 6) but will not charge anymore than 1A..Im sure they can pull more than 1A so im assuming im using the wrong fast charge ic.i have tested my design using resistors and the pcb design can draw 3A easily with no heat issues so its just the ic handshake thats not telling the devices charge more than 1Asaying that a Tesco Hudl 2 Tablet charged at 1.5A so the ic did talk to that correctly.this charger is just a charger. no data.im using a 750w EVGA ATX power supply using the 5v rail that has 20A to play with.

content: So I bought a Flir TG-165 about 4 months ago and just started using it recently for equipment repairs. Works fine for my purpose which is to see what gets hot on sparsely populated boards.Charged it up and used it about 4 or 5 times then I get a yellow line across the screen after the sensor refreshes the line disappears.I ended up contacting support October 26th, 2016 and they said it's probably an issue with the lepton sensor and I should contact repair@flir.com so on October 31st I did. So after hearing nothing from repair, I emailed the original sender back on Nov. 2nd to notify him I have not heard anything back and I also asked a few more questions. I got a response back Nov. 3rd with just about the same canned message as the original response. I also wanted to know the turnaround time which went unanswered.I was considering getting a Flir E-4, but now after this whole incident, I am reconsidering it.So I guess my question to you all is is this normal for repair?Is asking for a turnaround time unreasonable?

content: In other James Dyson news this week:http://www.bbc.com/news/education-37834857"Inventor Sir James Dyson is to open his own institute to train engineers, who he says are badly needed if UK companies are to remain competitive."Are any other R&D companies out there looking at trying to get degree-awarding status for their in-house training programmes?I know some companies effectively sponsor course modules within university departments so that their staff can take them for upskilling but this looks more like bringing it all in house.The UK is going to push apprenticeships much more from next year through reclaimable tax-credits (net cost to larger companies if you don't have apprenticeships). The definition of apprenticeships is to be broadened also so may capture more higher level training courses.Interesting times.rt

content: OK, to be pedantic, R134a isn't really "Freon".Many years ago, a friend of mine gave me a roughly 3 inch piece of 1/8" copper tubing filled with a little R134a and sealed at both ends. It was intended to demonstrate how refrigerants carry heat. After lying around for so many years, I decided to try to find a use for it. It so turns out that the cheap (and not so cheap) plastic cases for the Raspberry Pi are terrible thermal wise. I carefully bent that piece of tubing into a loop and epoxied it to an old NB heatsink on one end and a filed down penny (heatspreader) on the other end. I cut a hole in the case for the heatsink so it can mount on top.It's way overkill, but it sure looks cool. And it does indeed keep the CPU very cool.

Most are aligned all the same vertical / horizontal. I guess it makes sense because the traces have to turn corners anyway so why not put the chips on the board the best way possible as far as circuit design needs dictate. Is that the reason?Orange Pi PC

content: Not going into question whether it's viable problem for "Circuit Cellar", it would be semi-okay question, if they added something like "we skipped input sanity check" (as you usually do in such problems because it's just boilerplate code). Saying that, every XXI-century compiler will cut out that if(i) section during optimization (unless you define i as volatile). With or without warning message, depending on your settings. It's easy to check it out using for example GCC compiler explorer onhttp://godbolt.org/(just put -O1 or something in compiler flags to make it compile with optimization)

So now it has AC (Perfect for Texas)I have tried investing in fixing up laptops and reselling them but all I could say is that failed Due to me not realizing macs actually sucked THAT much. (Got them working but some wont even run google chrome!) It was 100% my fault for not doing the proper research to see that the OS updates and everything else apple does has caused me to be unable to run google rum or other programs in the app store, nor can these laptops update to the latest OS. with these laptops being from 2008 and only being 8 years old I would assume that they would still work for such basic functions. I had a laptop for about 12 years and it was still able to at least run programs I needed.(Although not super fast it still ran them.)So getting away from the stresstops I am in my final year of high-school with no job and no way to get a job as I don't have transportation (And am unable to traverse long distances by foot eg. 2 miles) I have a giant rant for people to read, laugh, and cringe right here for you to read.I will be trying to get on more often as its the small productive projects that keep me sane. So glad to finally be back, and will hopefully be able to work on a few things.
