content: I see yours is missing its hard cover thing like mine is. I just took it apart; date on the batteries is Jan 1999 which I assume to be expiry date? I have vague recollections of changing the batteries once since I had it, which would have been from new when I was at school whenever that was.I don't know why I bother keeping the calculator on my desk. I haven't really used it much in years since it's generally better to just use the computer.

content: The television advert I saw showed the Minimax being used to instantly rejuvenate a large dead car battery. What they didn't show is that the battery voltage would have instantly dropped back to a few useless volts once the Minimax was disconnected from it, but they implied (without actually demonstrating, for obvious reasons) that you could install the battery into your car and crank the engine with it.This is what instantly pegged my BS meter. Funny enough I can't find that particular segment in any of their online videos.

Academia at it's best.QR, Barcode etc all exist because they are machine producible, almost trivially machine readable, massively scalable (especially QR and other 2d codes) and instantly recognisable.These "aestheticodes" have none of these properties, they have to be produced by hand (that's the "point"), they are I imagine a much more complex computer vision task, they are not very scalable (not easily), and they are not even recognisable as containing data.If you want to HIDE some data in plain sight, an aestheticode might be partially useful.This is like an earlier Computerphile they did about some research into building a "guitar that carries it's backstory/history with it" or something, from memory it was waffle waffle waffle and what it boils down to is "scan this barcode we built into the guitar and it will take you to a URL with information".

content: Check with the carrier that will be sending the item as they will have specific information for each country. However in Australia, lithium batteries are considered a dangerous item andgenerallycannot be transported by air. Non-lithium dry cell batteries (zinc carbon, NiMH etc...) can be shipped but will need to be securely packaged to prevent short circuit.Some exemptions might apply even with Lithium batteries, such as if the amount of lithium is considered "small".The item should be labelled that it contains lithium batteries anyway, so you might find it will be transported by sea rather than air mail.My suggestion would be to ship the kits without batteries if possible. It would solve the issue and any headaches which might arise from it. You may also find it lowers your shipping costs.

The batteries are not Lithium, just the standard 1.5V AAA alkaline batteries (not 100% sure on the chemistry, zinc and manganese I think) and are coming packed (2 per pack, plastic sealed).I do know that the Lithium batteries cannot be shipped here by air, had an 'interesting' situation with RS Components few years ago when I purchased some lithium batteries from them in the UK and it took them 6 weeks to be delivered, cause it was by ocean freight, which I was told that was the shipping method at the end of the 4th week after I ordered them..

content: I think you'll be OK with bog-standard AA's, especially if they are packaged in blister packaging. At the end of the day check with your carrier. Their terms and conditions will stipulate what can and can't be sent. As long as you do everything correctly yourself, the rest is on the carrier transporting the goods to ship them accordingly as per customs documentation and manifests. You're not expected to understand every import law or aviation regulation, however you will need to read what you're putting your name and signature against thoroughly.

My memory isn't good enough to memorise the rules, to allow me to determine what's new or different, and saving a copy for later comparison is inconvenient. Also, a summary would save those who have already read the rules from having to read them again in their entirety.

always on LED in Bluetooth headset? - Page 1

timestamp: October 23, 2015, 04:39:46 am
content: I tore down an old Plantronics Bluetooth headset recently and I was surprised that there's a blue LED inside that always glows dimly, even when the headset is switched off. Even more perplexing is that it it completely invisible when the case is closed. The brightness appears to stay the same regardless of what the headset is doing. Measurements indicate that one end connects to the battery and the other end seems to sit at about 1.5V. Are they using the LED as a voltage dropper to power some standby logic?

Something likehttp://www.maplin.co.uk/p/rolson-2-led-12x-18x-25x-and-35x-magnifying-visor-n70fkallows you to put two lenses in series while wearing your normal eyeglasses. For me, +2.5D reading glasses and the 2.5* (or 1.8*) lens is sufficient for 0603/0.5mm SMD work.They are also useful for many other purposes, e.g. peering inside scopes etc.

Rigol DG5, DP800 and possibly others to get new bootloader again - Page 1
Forum section: electronics / general

author: Asmyldof

timestamp: October 17, 2015, 10:35:32 pm
content: Hello All,My Firmware Upgrade subscription with Rigol just notified me of a packet of updates which, for the DP800 and the DG5 series, included Bootloader updates, required to install those FW versions.I have a tingling suspicion they may have combated some of the sniffing going on, although I have no real proof of this yet (I haven't the time this week to flash any of my devices and see if anything changed), but I wanted to just send this information out into the world.I'm only "subscribed" to DG5-series, DS1Z-series, DS4-series, DSA815 and DP800-series, so there may be more that get the new bootloader. Undoubtedly rolling back FW with that new bootloader will be nigh impossible again.You guys can do with it what you will. (In terms of buying to be ahead of new units having the bootloader, or just being careful with which updates you do and do not install).

timestamp: October 18, 2015, 01:34:21 am
content: Are you sure they've actually been updated? The DP800 one always mentions the bootloader along with the normal firmware, but it's just whatever is current regardless of whether or not it was actually changed. Presumably they do that in case you are trying to update from a really old version and need the bootloader.

author: Asmyldof
author_rank: Regular Contributor
timestamp: October 18, 2015, 07:19:43 pm
content: Update Information mentions the requirement to install the bootloader supplied with the e-mail before being able to install the new firmware.Previous two e-mails for any of the devices did _not_ include a bootloader at all (I'd have remembered, because I'm always weary for flashing bootloaders if I'm not having specific issues).That is the only "surety" I have, as I have not tried flashing yet, due to limited time right now. Just wanted to FYI the world, as by the time I have had actual time to verify, it may not be as much use any more.
