content: Most Australian engineers are not interested in sport.Generalising here, I have noticed in the electronics engineering environment, sport is rarely mentioned. Many engineers know nothing about football, but that is partly because most of them were born overseas. At least we have footy tipping at work. But in the "secular" world, it is a different matter.I did hear we beat the Poms at rugby. Here in Victoria, few people play rugby and there is little interest. It is AFL here. Go over the border to New South Wales and it like stepping into another country with sport - rugby is the go there and in Queensland. Even so, there are AFL teams sparsely represented in other states and some of them are very good. Unfortunately, football is not so much about sport, it is about money. It is a business. Hence why some coaches and clubs swap clubs according to money offered, not loyalty to the local club where they grew up. There are people here, and I am sure in your country, where sport appears to have become a substitute for religion. But then again so has the endless pursuit to get more stuff.

I'm one who was born here and has zero interest in any organized spectator sport, especially if there is a ball being either hit or chased. The whole bread and circuses, team-cultism thing just pisses me off. Especially at times like last night (Sunday night) when my neighbor set up a big LCD TV in their back yard and had a very noisy party till about 11:30pm due to some match. I'd wanted to go to bed early. Thanks neighbor.

Quite a nice solution for reducing assembly costs.The "Siri remote" is also pretty interesting... It doesn't look very cost-optimised yet, there's a ton of power distribution ICs strewn all over it (including two of those cute tiny DC/DC modules).Also interesting that they're using a TI low-power DSP chip to handle the voice processing to go along with the STM32L main chip. Since it's Bluetooth LE, this is pretty interesting... It must be doing the front-end of the speech recognition on that DSP, to reduce the data volume to be sent over Bluetooth LE (doesn't quite have the data rate to send decent-quality voice).

content: I don't see anything wrong with what he's claiming. It should be possible to harvest a couple microwatts of power, which is sufficient to power a low power sensor transmitting occasionally. With the right matching network, and in nearby range of wifi and phones... I seem to remember a paper on this a while back which was able to get into the milliwatt range but only by modifying wifi router firmware and transmitting at over 1W.Also, it wouldn't interfere with existing networks if it's only a receiver. Absorbing RF doesn't mean the transmitter has to pump more power out to compensate. But apparently it's really easy to become a "mobile technology analyst" and claim things like that. Perhaps I should try that.

Or how it compares with other technologies e.g. like PV (for fixed sensors) or piezo (for wearables)?
Suggestions for Tape Backup Software - Page 1

content: I'm currently using Windows Backup on Windows 2003 to backup my data to LTO tape. It actually works quite well but its *very* basic and the scheduling is a bit cumbersome.I've tried other software in the past and it's either way too complicated for what I need (e.g.: BackupExec) or it doesn't support "spanning" over multiple tapes (yes! I actually tried software which terminated the backup when it got to the end of the tape, rather than asking for the next one).What does everyone else use? Ideally it should be free, but I know I'm limiting myself when it comes to tape backup software. It needs to run on Windows 2003 and ideally support software and hardware encryption.

The North and South ice caps are 3km thick.There are also evidences that there has been liquid water on Mars :- Geological evidence from the aspect of fluvial basins.- Hydrated material like clays which testify of existence of water, but in remote time.As far as I understand the new result is not evidence of water, but of hydrated salts. This should be the evidence ofpresence of liquid water in a more recent time, but not yet lakes or rivers.

content: The detailed schematic will be proprietary information. The block diagram for low drop-out regulators is essentially the same: a voltage reference with an op-amp and a pass transistor in the feedback loop.https://en.wikipedia.org/wiki/Low-dropout_regulatorwww.analog.com/library/analogDialogue/archives/43-08/ldo.htmlNormally, if the regulator has a positive output, the pass transistor will be P-channel/PNP. If the output is negative an N-channel/NPN transistor will be used. However it's possible to use an N-channel MOSFET on a positive output LDO but a voltage multiplier circuit is needed to bias the gate above the output.

author: PeteH
author_rank: Unknown
timestamp: September 26, 2015, 09:20:39 pm
content: Its likely a PNP output stage. The low drop out is just the Vce saturation curve of the bipolar transistor. The part operates at very low VIN, and you can see the ground pin current skyrocket at saturated or low VIN-VOUT. This gives away the fact that the part is pulling tons of base current out of the PNP to try and regulate the output while in and near saturation.

content: Just the other day I found the HP memory projecthttp://hpmemoryproject.org/timeline/company/memories_home.htmwhich has memoirs of some key people who worked there for 40+ years. HP is a very special company for me; I used their equipment in my high school (instead of tek!!) for my electronics based science project (it was a clap switch), and then in college and grad school even after changing my major a few times, I ended up using HP GC and HPLC; so it was safe to say that I got great kicks reading about how it all started and how they slowly expanded to include such a vast lineup of instruments.I am wondering if any of y'all know of other projects of these kind for your own favorite companies. Examples could probably include IBM, bell labs, Varian (used lot o their stuff too) etc.

content: Hey all, so saw this on local classifieds, and always wanted one, it's pretty rough, definitely well used, but if it was shiny and new that would take away from the charm, and for only $40, I couldn't resist.I want to fix it up, to do so I need a sort of washer that helps hold the boom mic (actually as I'm typing this sentence I found a fantastic guide, so I might be able to find partshttp://www.davidclarkcompany.com/files/literature/Parts%20List%20H3335.pdf), and the clip to hold the wire in place as it's partially broken.I should be able to re-seat the microphone fairly easily, first though I will test to see how it sounds, and what the microphone quality is like, because I am thinking of taking the parts from another headset and swapping them over to use it as a gaming headset. I have my razer megalodon but that isn't the cheapest thing to use for parts, and I want to keep it analog (no USB connection), then I can keep the ridiculously long cable that it has. Also tempting to add a little orange light in the mic for looks. Another feature that this has is a button to cut out the mic built in which is nice.

It is shown around minute 33 in the first video. By chance, I came across it when I visited Harvard University a couple of years back. It turns out that it is hard to find rest rooms in the place and we were referred to the Harvard Science Center. The Mark I is on display right on top of the stairs to the rest rooms so the visit was even more positive than expected...https://en.wikipedia.org/wiki/Harvard_Mark_Ihttps://en.wikipedia.org/wiki/Harvard_Science_CenterAs it turns out, it was the Mark I that Grace Hopper started programming on under Howard Aiken's leadership. This is the "little old lady" in the 1st video, talking about the Mark I. Aiken was the inventor of the Mark I and it was built by IBM. It also turns out that this is the very machine that popularized the phrase "software bug" since they literarily found a bug (a moth actually) stuck between two relay contacts!https://en.wikipedia.org/wiki/Grace_Hopperhttps://en.wikipedia.org/wiki/Howard_H._AikenIt was also the machine that pioneered the "Harvard" architecture, i.e. separate instruction and data paths for the CPU.
