I need to measure the intensity of the light to a resolution of ~12 bits.Looking for a dev board or set of dev boards if they exist... or equipment recommendations to start as our point of reference.

content: It will receive a fairly directed beam from an industrial tachometer, advertised as "works in direct sunlight", so my guess is that it's at least as bright as the sun.We're trying to just buy something quickly versus build it from discrete components. Even just an analog output read on our scope would be fine. Time is more the issue. We're passing the cost onto our customer so money will not be an issue until they get the bill.Unfortunately all I found were discrete components and slow ambient light sensor dev boards. Our typical go-to test equipment suppliers didn't have much either.Thanks again.

Strange probe - What is that? - Page 1

timestamp: March 31, 2016, 04:59:14 pm
content: Throwing this in here, because I have no idea where to properly put it.Went through some stuff, that I had put aside, and found this strange probe-ish thingy. If I remember correctly, it came together with my Fluke 93.It's got a banana plug tip on one end, and a coax and BNC on the other side.No marking, no labels.It appears to have some 25 kOhms of inline resistance along the centre conductor and some serious capacitance.Other than that I played a bit with it and it doesn't seem to allow DC voltage to pass. (Tested up to 30V or so)Does anyone of you know what this strange contraption might be?And yes: The white collar around the banana probe tip appears to be molten.Don't know if intentionally, but with some serious heat.

content: The huge list of worrying, warnings, at the end of the video. Are making me wonder which is more dangerous. The Hoverboard (batteries), or that smother device.Maybe LiPo batteries, should have been designed to be inherently safe. Like many Lithium Ion batteries have been. E.g. Put something in which opens up the battery contacts (electrically), if the temperature rises above (a safe level, such as) 50 degrees C, or some unsafe threshold. Other safety precautions, may be needed as well.Or even chemically design the batteries to be safe, right from the start. If that is possible.I wonder how many of the LiPo battery fires, are really caused by shoddy/unsafe Chinese products/parts, rather than inherent LiPo battery problems. Or faulty chargers.

timestamp: April 02, 2016, 11:35:55 pm
content: Inherently safe. Higher power density. Cheap. Yeah, sure.In the RC world we have decided to accept a little higher danger level to get the price and performance. These LiPo sacks are a part of a risk mitigation strategy to make the danger less while still getting the flight performance and price point. Other recommended strategies in the RC world include never charging un-attended, charging on a fire proof surface, using a high quality charger with appropriate charging monitors and algorithms, monitoring battery physical condition, storing the batteries in a fireproof container and charging in an area with adequate ventilation. These practices don't eliminate the chance of a battery fire, but do minimize the damage that occurs from such a fire.The problem is that there are always some who don't get the risk message or just don't care. The hover boards seem to have thrown caution to the wind, and obviously didn't adequately warn their customer base. I don't know if they warned them at all.

Webcam Freeware for simple preview? Suggestions? - Page 1
Forum section: electronics / general

timestamp: April 03, 2016, 02:27:25 am
content: Hi folks,I need a simple webcam program that will display a DirectShow webcam (either my built-in laptop cam or one I plug in from USB) as full-screen or windowed, with the option to possibly zoom in if needed. I do not want to record anything, or apply any effects, or have any other features. Basically, just a small Windows 7 compatible program that previews webcam input with a few options to modify input resolution and other stuff, and go full screen if needed.The reason I need this is for doing a presentation. I have my laptop plugged in to an LCD projector and during my PowerPoint I want to be able to switch to the webcam program and show a live image of a webcam microscope I have with me at the podium that's plugged into my laptop as well.I've tried Webcamviewer and Amcap and Yawcam and manyCam. These either have no full-screen option, or time-out after a certain time as they are not free, or are bloated and too feature-full. There *must* be a simple program out there, I just haven't found it. Anyone have any suggestions?

content: Thanks... I did try webcamviewer already. Only version 1.0 works on my system with my plug-in webcam. I have tried the newer versions but they don't show it (don't know why?). The problem is, it doesn't go full-screen. It enlarges the window but the webcam only takes up a small portion in the middle instead of stretching to expand to the window.Same goes for Free2X Webcam recorder, which I just tried now. It will not go full-screen. AmCap is the only one that does it but it is not free. I may have to use ManyCam although it is quite bloated.I'm sure there is some old freeware sitting around somewhere that is a tiny stand-alone program.UPDATE:I just tried IPCameraViewer. It is more than I need, but it does work with my camera and does full screen. The only annoying part is it puts up a time-stamp on the bottom of the image and I can't figure out how to remove it. I guess it will have to do for now...One other thing, if I try to use my webcam in 1280x720 mode it is choppy and freezes up every few seconds for a while, and then recovers. When I switch setting to 640x480 it is smooth and I get no frame-drops. Is it my USB speed? It only outputs 1280 x720, 640x480 and 320x240 mode at 30 fps MJPG 24. So I bet the bandwidth at the highest setting is an issue, or there is a bug.OK... I found an old Amcap version herewhich does the job.... Simple but effective, only 140K footprint, goes full-screen:http://prdownloads.sourceforge.net/btwincap/wdmmiscutils2.73.zip?download

This just started yesterday.Previously the only trackers were from doubleclick and google. Those could be blocked and youtube would still work.edit: Strange, the beacon actually doesn't show up on this computer if youtube is loaded directly, it only appears with embedded videos. On my other computer it shows up when youtube is loaded direct. Same browser, same Ghostery, only difference is Win 7 64 vs. Win 7 32.

content: They don't seem to be claiming it can fully power the car, just that it's another form of energy harvesting like regenerative breaking. I can imagine it's way too expensive for practical use right now but in the long run things like this could give you an extra few miles range using energy that's normally just wasted. In the long run I could imagine things like this, suspension that generates electricity, those things that stop you slamming doors, solar panels on the roof, etc while adding relatively little themselves would all add up. Like when car designers go around shaving off a kilo here, gramme there, fraction of a gramme elsewhere adds up already.

Three different 3cm x 3cm boards, and one 10x10 board. Standard (cheapest) 2-layer PCBs.I know from experience that if you order anything _but_ PCBs in the same order, the order can get "stuck" for a while after they show up as "completed" on their website, until they're actually shipped out.
