content: Hello,I don't know exactly what the 5mm is referring to, but it has something to do with how blunt or sharp the point is. Compare the pictures of the 5mm and the 3mm.http://www.tooled-up.com/Product.asp?PID=13175http://www.tooled-up.com/Product.asp?PID=20789I would also recommend a machinists forum(unless someone here can give you an informed answer). Maybe CNCzone? They have a lot of machinists(i think it's the world's largest machinist forum).Joshua

content: it aint blunt, it will create a very good hole on your skull if it got punched on your head, and they are meant to be punched on a really hard stuff. 5mm is either the length of the tip (from tip to tapered corner) or diameter of the tapered corner (that is near the tip)edit: from rough estimation (picture), more likely its the diameter of the taper.

Such a high velocity at relatively low altitudes created skin temperatures up to 3400°C (6200°F), requiring an ablative shield to dissipate the heat."And as an example of the left hand of government not knowing what the right hand is doing:"The Sprint was in operational service for only a few months in the Safeguard program, from October 1975 to early 1976."Quotes from wiki.

content: The other morning on the way to open the front door at work I saw a small electronic module on the street. Not a bomb, just in case anybody was thinking that, I know what that looks like, but a small flashing LED unit from a bouncy children’s toy. Still worked, just no ball or outer plastic clear casing, and 2 very flat CR1212 coin cells still powering it.On the round thin double sided PTH PCB there is a COB, covered with white epoxy so as to match the top and bottom white silkscreened board. Nothing special, it is a timer that turns on the LED's for a few seconds after a trigger pin, attached to a spring vibration trigger, is pulled to 6V. Interesting is that the Little 2 pin 3 colour LED's have a small sequencer inside, and they match pretty closely for the few seconds they are powered.This is a view of the small square LED, showing the small Ic inside, the wire bonds to the 3 separate LED died on the other lead.

content: If you really want to start business, I'd advise to get more professional tools you can trust. ERSA I-CON nano as the soldering iron and Quick 861DS hot air. That of course is way over this junk in price but will serve well over the many years. Otherwise if tight on money, get some really good soldering iron, still suggest I-CON nano and some cheapo hot air like 858D models. Don't forget that likely you'll need to pay VAT +, probably, customs duty when importing stuff from China.

The surgery also has its consequences and I am still paying for it. The surgery costs have also been rather high and I find myself scrambling to try and get caught up on everything in my life. At least I can do some work I need to live, but my workshop and videos are a very low priority in place of trying to gt back on my feet. Hopefully soon, next month I think, I will be able to climb out of this hole and make some of the videos I have promised.

Network card causing STOP error on Windows XP (Soldering Thread) - Page 1

content: Just something interesting I came across today when rebuilding an old PC. The system would crash upon first boot after installing Windows XP. Pulling out the network card solved the problem and on closer inspection of the card itself (just a cheap Realtek-based card), it looks like the soldering on the main chip wasn't inspected properly (although there is a "QC OK" sticker on the card).

You print out the pattern you want, then run it through the cutting plotter and you have whatever shape and size you want.For real bulk applications you want a label printer, for which you can get a specific tape with precut shapes and sizes. You pick your printer and then consult the manufacturer.Also, after a quick google search, this company looks to offer what you want:http://www.onlinelabels.com/material_white_matte_labels.htm

Once stuck on, they won't come off (although they are removable with a some effort). They fit perfectly on EEPROMs; not sure if they are a little too long for your purposes. As with all Avery products, the templates come included in Microsoft Word. The metallic ones are great for covering the UV windows on EPROMs.Attached is a photo I just took...

content: I will also add that if you're looking to buy laser or inkjet printable labels, you probably won't find any smaller than 10mm across one edge. The labels still need enough area to be able to bend around the printer rollers and not lift off the page and bugger up your printer.If you need small labels, you might look at just getting yourself one of those hand-held label printers (like Dymo or Brother products). They have tape widths down to 6mm and they can be as long or as short as you like depending on the font size. The other obvious advantage of using rolls of labels instead of sheets is that you won't waste an entire sheet if you just want to print one or a couple of labels at a time (you're not supposed to feed sheets through printers multiple times).I have a Dymo LabelManager 280 which works as a standalone printer but also has a USB port so you can design, save and print labels on your computer. It has a rechargeable Lithium Ion battery. The only downside I found was you cannot charge or power the printer from the USB port if the battery is dead, you must use the included DC plug pack which I thought was a bit stupid (so don't loose the plug pack!)

The setting resistors measure correctly, and the circuits they are supplying don't seem shorted or anything. Also, it looks like it's got pretty hot in the past...

content: So simply making a hoax bomb is illegal now in 'Murica? I believe the 14-year-old never said "This is a bomb" or showed signs that this was a legitimate bomb threat, so I don't understand on what ground they are justified to arrest him?And if making fake bombs is illegal now, then hang on to your hats, because then fake weapons would be illegal too, or not? And so would be shooting people with fake weapons, and suddenly paintball would be illegal, if we applied the same rule with no big stretch of the imagination.I guess you have to be careful ordering one of those now onamazonEDIT: There's already a thread about this9th Grader Arrested in Houston for making ... a clock.

I had a battery pack (3 lithium ion cells in parallel) inside of a sh*t ton of electrical tape. many people have asked me about it, all of which being students. never was I asked by a teacher or the school police officer about it although they have seen it. Scary to think that they will react to a clock and not something that looks like it could be an actual bomb. Maybe it's just because i'm white.

content: The power out control on my ham radio linear amplifier is labelled 0-11 but nobody around here got the joke. So, version 2 of the front panel changed the label from RF POWER to MEGATHROBS which does get noticed once in a while. The biggest problem was getting the numbers spaced correctly around the dial because most switches and controls are either 0-10 or 0-12, I ended up using a 0-12 dial label, erasing the 12 and then rotating the image by 15 degrees.

Most fakes are much lower capacity flash or sdcards that have had there spi eeproms reflashed with lies to pretend to be much larger than they are. They are also pretty shit to begin with, like an 8GB card will be "upgraded" to 64GB, but was a manufacturers 8GB reject to begin with before the counterfeiters got hold of them.FAKEFLASHTESTis a better tool, at least for quick verification. If it fails that (without waiting days) then it is a duffer for sure so no need to waste time with a full test like h2testw.I've had a few ebay specials and even mainstream sellers refund/replace on the fakeflashtest results alone.

Maker Farie itself is also hosting a Day One Happy Hour from 5:00pm to 7:00pm.To make things simple I will just be in the bar around 5:00pm on Saturday sporting a Negative Feedback shirt and if I find the time possibly a LoL Shield as a belt buckle. In addition to that I'll bring along my Micro Current and have that out as an addition signal flare.Tell me about some cool project you are working on and I might even buy you a drink!Hope to see some of you there!Ryan

However there is no mention of what school it is.Student loans have a very long pay back (they start when the student graduates)My only connection I have with Kiva is I loaned $50 to farmers in Albania to buy cows.In general the way this works is the people already got their loan, and the sponsor is asking to get re-paid and interest is charged and kept by the sponsor to make a profit and pay for bad loans.I came across Kiva from another member here on a topic I cannot remember.Kiva FYI --->http://www.kiva.org/about

content: Hey folks,I have noticed a few times now in my area (Toronto) some guys selling NOT speakers and HiFi systems or watches, but these new "Self-Balancing Smart 2 Wheeled Mini Scooter" things (See photos I snapped while one of these deals was going down in a parking lot by my house).Anyone know more about these? I don't know what the guy was selling exactly, or the price, but I assume anything out of the back of a car in a parking lot has got to be shady. Either the toy is going for a good deal higher to earn a profit, or made very cheaply compared to what he is representing it as being.I looked some up on eBay as well and saw a big price range. Has anyone torn apart one of these things and compared the cheaper and more expensive models? Do the electronics look well designed?

Alibaba a bit less. But still, it's not chump change. That is a fair bit, who would risk buying it online, and from the back of a truck/van/car? Crazy people...Either you fall and badly hurt yourself on one of these if it glitches or it explodes because they are using the poorest electronic components and wall charger imaginable... And for that kind of money? Geez. There are a lot better transportation options in that price range....although most users say how much fun they are, we'll see how much fun they are having if their expensive toy lasts only a year.
