content: Some months back, while scrounging around you tube, I came a cross a program called something like "how hard can it be" or some such thing. This episode was about high power rockets / hybrid rockets. Over all it was an interesting over view. years past I had put together mall kits for school / scouts what not but now they are a little more sophisticated.I boughthis kitform a guy that totes around his shop in a trailer at a local meting. The crowd at the meeting look very much like the same sorts you would find at ham fests / electronic flee markets. There is a certification process to be able to buy the larger motor sizes. The process is basically to check that you can build and fly at least one rocket or significant size.The kit is pretty much a sand and glue together thing. Though with bigger motors people will also put an instrument package to to trigger parachutes of different sizes and to help recover the rocket after the fact.Went to "the launch" yesterday. It was really cool. basically two house form home. People were tail gating with their families. Two things that stand out were that there were a lot of school age children there with their families shooting things they made for fun or for school. And second how much more noise a 38mm / 54mm/ 75mm motor makes vs 18mm A/B/C motors for the regular models.Anyway, i am already scheming on how i can over complicate my next build with electronics and radios.....Here is a pic om my little one helping me pack for the day.

The resulting board can be larger than 100x80mm limit and fully editable as long as no component is moved, so for example it's possible to partially connect the sub-boards to satisfy a common requirement of low-cost PCB houses.

If it was mental problems or drug abuse, that should also be exposed as well, as it could help others get help. There are very few cases where suicide is an acceptable answer to a problem.Just like with Aaron Schwartz, the suicide itself might be shocking and sad, but it's not the real story. The real story is what drove him to it and what can be done to prevent it happening to someone else.

content: Suicide seems to be an extreme and ineffective reaction to policy brutality, even if when raped by a female policy officer.That's why I am a big supporter of community policing: people in a community should have the right to determine which laws to enforce (and which not to) and how it should be enforced. That way, we can all move to a community where law enforcement is customized to our personal liking. No more police brutality problems.Otherwise, the only way to get rid of police brutality is to get rid of the police.

author: ajb
author_rank: Super Contributor
timestamp: January 03, 2016, 08:16:30 pm
content: Unless otherwise noted, AC voltage is specified in terms of the square root of the average of the squared voltage, or"root mean square"/RMSfor short. This is a useful way of specifying voltage because with many loads the amount of power applied to the load is proportional to the square of the voltage--so if you double the voltage, you quadruple the power. So by specifying the RMS voltage, you're implicitly specifying a waveform that when applied to a resistive load would result in the same power being applied as an equal DC voltage. So for a 130VAC lamp, you'd need 130VDC to run it at nominal power.It's worth noting that for common waveforms there are simple conversion factors to determine the peak voltage from the RMS village and vice versa--for a sine wave, Vpeak = Vrms * sqrt(2). For more complex or nonrepetitive waveforms, you just have to measure a bunch of points, square them, average the squares, and then take the square root of the average. Cheap ac-reading voltmeters do the former--measuring the peak voltage, and apply a factor that assumes a pure sine wave--, more expensive 'True RMS' meters effectively do the latter.

content: Hi folks,I thought I'd share a teardown of my old Kaise Electronic works SK-33 multimeter. It had been sitting around for years, given to me by my father. I never managed to really use it for anything but recently tested it out and found it wasn't working properly. Since it looked like it was ready for the recycle bin and I have a number of better multimeters, I thought I'd have a crack at it and see what was in there. Turns out one of the resistors was blown. Easy enough to figure out the value and fix but not worth bothering to fix, as I need to clear space anyways.I was happy to see the construction was very simple and to the point. The schematics can probably be easily reverse-engineered. It is a classical old-style analog multimeter (volts ac/dc, ohm, current). It is a great example for beginners to learn how multimeters work. I see a couple diodes placed in reverse which are going to rectify the AC for AC voltage readings, a capacitor for smoothing, an ohms dial to adjust for zero, and another "pot" that is adjusted inside to calibrate. Otherwise, it is as simple as can be.

If it contains data of any sort, it should look random (DSL, DTV, CDMA...).I would be inclined to suspect a spread-spectrum SMPS, since the roughly curved amplitude suggests frequency modulation.Can you tell if there are similar patches at harmonic frequencies (below and above)?Tim

content: My car has some kind of metal coating on the windshield for blocking heat and UV radiation.Problem is, this coating also blocks RF. For example, toll road transponders have to be placed at a specific spot on the windshield where the coating is not applied, else they won't work reliably.This also means that GPS reception sucks. Is there any kind of GPS amplifier for cars like mine?

But I think the killer was the fact that not only did I NOT deride Dave, but suggested he might have something valid to say. His last reaction was extreme and I put together a final comment, but when I tried to post it, it just disappeared.I know some of the technical points I made might not sit well with Engineers, but it was an effort to encourage discussion rather than belligerent rants.Silly me.

And no mention of Linux at all, but I doubt they wrote their own kernel, so it is either Linux or BSD. Lack of technical documentation on that site is just appalling.

It's even stranger that I could unplug the unit (it has a RTC battery), plug it back in the next day, and it would be 4 hours ahead.

Mistyped a part number one day and up popped 2 new Tek scopes, which I ordered. They arrived in internal post 2 weeks later, and I surprised everybody by walking in with them, as we had been trying for years to get new ones to replace the old ones which had died. Took the original division who had ordered them to notice, and they were told something along the line that "You snooze you lose", as they did not lock the item in stores to issue to themselves only. A flag in the field, quite useful to store stuff we did not need regularly ( one a decade) so it was not on inventory, but sat in stores and they looked after it.No punched cards, just a load of paperwork, 2 stores operators and 2 operator terminals connected via a secure data link and a dedicated microwave and radio link to a central computer.

Sertainly, this will make the sivil servants jump with joy. The hard 'c' will be replaced by 'k'.This should klear up konfusion and keyboards kan now have one less letter.There will be growing publik enthusiasm in the sekond year, when the troublesome 'ph' is replaced by 'f'. This will reduse 'fotograf' by 20%.In the 3rd year, publik akseptanse of the new spelling kan be expekted to reach the stage where more komplikated changes are possible. Governments will enkourage the removal of double letters, which have always ben a deterent to akurate speling. Also, al wil agre that the horible mes of the silent 'e's in the language is disgrasful and they should eliminat them.By year 4, peopl wil be reseptiv to lingwistik korektions such as replasing 'th' with 'z' and 'w' with 'v' (saving mor keyboard spas).During ze fifz year, ze unesesary 'o' kan be dropd from vords kontaining 'ou' and similar changes vud of kors be aplid to ozer kombinations of leters.After zis fifz year, ve vil hav a reli sensibil riten styl.

The guy interviewing me was insisting I was too clever for this summer job as it was assembly work, and I should really go into the military like him and get a proper engineering degree. Ok, longterm he was probably right. But I needed some money NOW. I didn't have a mummy and daddy to support me. I really didn't care about demeaning myself by production line soldering - especially at the rates on offer!I would say this is "reverse sexism", and it's funny enough that about a year later I met a new girl in a rock club on a weekend and we had a lot in common. Same birthday (she 1 year younger), she had done the same City & Guilds course, only she got the frikkin' job I was after and ended up as the line manager to all the girls.All I can say is she was considerably richer than me at the time we were together. (Oh, and I switched to IT)ETA: ... and my first apprentice job, of course all the service engineers were lads / men (the men had beards too!). All the "admin" were girls / women. All the warehouse were lads / men with a seemingly lower standard of intellect to everyone else. Oh the sales guys were all lads with shiny suits and gift of the gab.
