content: Sorry guys, but I had to sign up as I was yelling at my computer. Long time listener, first time ranter.[Talking about electric cars]Chis: "...there's ones that actually drive the camshaft which is actually making the wheels move. Right?"Me: "Crankshaft, NOT camshaft."Chris (talking about Bob Simpson): "...he actually has a direct drive, where it actually drives on the cam shaft..."Me: "Well, that would probably be the drive shaft"Dave: "They don't actually ... drive the wheels through a cam shaft"Me: "BLAAAARGH" *goes and signs up on the eevforum**Chris goes and says camshaft about a dozen more times"I thought this was common knowledge.

Wankel rotary engines similarly use ports. I seem to recall hearing about electro-pneumatically operated valves on some new engine designs?

content: A missed point in the discussion is that while small geometry silicon circuits are much more likely to be 'flipped' they also present a much smaller target. The probability of a particular bit getting flipped has probably gone down significantly with the shrinking dimensions.As for cosmic ray bit flipping in personal computers I doubt even 1% of flipped bits would show a noticeable effect. Would you notice a single pixel on this page being a bit off colour?Flipped bit error rates should be easy enough to measure on PCs with ECC memory. I have a server motherboard with ECC. It also has a memory scrubbing option. I never found a way to inspect or log ECC activity.

content: Why doesn’t the Toyota Pious have plug-in capability?Because like that EV evangelist Bob guy said the secret of long battery life is to not use them.From what I read the Pious only uses the middle 40% or so of its battery capacity. It doesn't charge the batteries above 60% and won't fully discharge them without pressing the EV button which American models don't (or perhaps didn't) have.If it had a mains socket owners would want and expect to be able to deep cycle the batteries daily and end up having to replace them every 2-3 years.

As I am listening I like to follow the links in the breakdown of the cast below the player.My suggestion would be to have these links launch in a new window instead of using the window that the amp hour is taking place in. If I remember, I can right click and launch in a new window but maybe its possible to make it do this by default? I don't know much about web stuff, its just a thought.

content: Thanks guys for mentioning my on WOTH. Yes i do play Dave's video's + The Amp Hour, I do try to pick and choose but sometimes so rants get thought like the Renesas Video American money rant. But it was a great subject, it got us talking about some of our own failed systems like the Sacajawea dollar coin, the two dollar bill and the gold standard (probably should go back to).The most common request video is the fluke multimeter destruction #66, we did a spin off of it but instead of a fluke meter it was how far can you toss an ipod safety. From 50 feet the student had to design a system to keep the ipod safe, if it lived they get to keep it. We used shipping shock sensors on the elimination round but used live ipods on the second round.The Sylvia's Super-Awesome Maker Show was a great hit as well thank for mentioning that. I had no idea that show existed. I have incoming students that have no idea about electronics and we actually use the same drawdio project for the exploratory students. Exploratory the students basically spend a week in each trade to try them out.Do you guys have F.I.R.S.T. robotics out there? Would be a great show, get to see some amazing work from high school kids doing engineering and electronics.See yeaMr. JYour Vocational Electronic Engineering Technology Teacherps. Mr. J came about my first year teaching, there was five other Mr. Johnson's so the name kind of stuck.

Ok a nice work surface and storage area are a given but what do you have thats really handy but not immediately on the must have list. One that is on my list is a shadow board, like a hanging wallboard you clip your tools to with an outline of the tool that SHOULD be hanging there you can see at a glance if something is missing, really helps to prompt a tidy up Lol.

content: This is just my opinion, FWIWWhen I built my mechanical shop I did the entire wall behind the bench with PegBoard (which is what I presume that you're talking about). That's about 12' long and 5' from the bench to the ceiling. I absolutely loved it .... for about a month. I now hate the stuff so much that this summer I'll be tearing it all out and putting up sheetrock.*MY* problem with pegboard is that no matter what you do, it looks cluttered. Stuff hanging there that doesn't get used much will get dirty. There are cheap hooks, and expensive hooks. If you get the cheap ones, the hook falls out every time you touch the tool. If you opt for the expensive ones, it can get VERY expensive by the time you have everything hanging. Tools hanging there, even with outlines, are an invitation for anyone to grab a tool fully intending to return it, then they never do.You may love the stuff and it may work well for you. For me, however, I've suffered the crap for 5 years, and a year ago went and bought a good tool chest (locking). I'm much happier.

content: Pegboard is indeed the correct generic term, thank you. I like it because I'm not tidy enough to use a tool box correctly, six draws and a tote tray to search is way too much. I use a variety of methods to hang things from cup hooks to magnetic strips or even those springy c shaped clips whatever works. As you say pegboard is an open invitation to borrow tools but at least I know it is missing and can usually track down the culprit (Kids or missus) before it goes AWOL, keeping the Lab (read shed) locked helps too.As I am doing a complete refit of the Lab (New Shed) any tips are welcome ie power outlet placement tips.They always seem to end up in the wrong place.Tools, which ones? just about any usefull tips you may have come across when doing your rebuild so that I can copy or avoid any mistakes

content: Watches!I hadn't really noticed it myself until you mentioned it, but my watch habits have changed. I'm more Dave's age than Chris's but I rarely wear a watch now, I mostly use my phone, but I'm usually at a PC or in the car which have their own clocks anyway. It probably helps that my phone isn't a smartphone. I pick it up, press a button and read it. I miss my Nokia 6210i which didn't have a colour display, so it always showed the time! But if I am going somewhere important, whether it be an interview, a formal dinner or whatever, I feel lost without a watch. If it is a geek thing, then it has to be the Casio CFX-200 (see my profile photo). It doesn't have the hex/bin mode of the CFX-400 but I much prefer the style. For something posher, I wear a modern black anodised analogue watch with luminous hands. I find analogue watches are useless at telling absolute time, but are great for relative measurement. I used to have a combination analogue+digital watch, which was in theory the best solution. In reality it was just ugly and clumsy to use.LVDC home power? Won't happen. Two wiring systems in every home? Clumsy as hell. Especially when you consider the efficiency of small power converters, there is naff all efficiency gain to be made.Space is 100km guys, not 100,000ft (http://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_line). NASA use 122km as the start point of atmospheric drag for re-entry, so you would need to be well above that for orbit. The USAF "space" thing is absolute guff, purely a gimmick. Concorde regularly flew at 60,000ft (limited by legislation not plane performance) and you could clearly see the curvature of the earth and a dark sky. No space suit needed, just a leather armchair, champagne and smoked salmon. 41 years after it first flew, and the engineering on Concorde still utterly astounds me.

We are more concerned with super sonic flight, better fuel economy for hypersonics, metamaterials, and various electromagnetic applications. Its a strange group where most of the people are physicists and not engineers. This makes for an interesting combination since sometimes the physicists aren't current about the forefront of the engineering field. So as engineers we sometimes go "You want a device that does WHAT!?!".Anyways, Dave share some pictures of your dogs!

These are normally controled by a stand alone pc (does not need to be very powerful) they take the standard gerber files and convert them to Gcode and can route a 50mm x 50mm (2"x2") in less than 1/2 hour.Check outhttp://www.machsupport.com/for some VERY nice software and do a search for cnc routers and check out the specs.This can prove a very cost effective alternative for small quantity boards with a fast turn around requirement.I'm in the process of building one from scrap bits and pieces (ie slides from an old printer and scanner etc) but then I am environmentally friendly (cheap?)

It was a huge expense, but we ended using the milling machine only: the oven needed to be calibrated for each board, the stencil required expensive material and the press took a long time, while giving not so good results.A good feature was the method for vias "metallization", which required some simple tools and a conductive polymer paste.I think the CNC machine could be worth for a company which makes heavy prototyping, even if it costs a bit!I'm surprised of the 6/6mils Dave could achieve!

content: It appears that when trying to save the mp3 file in Chrome, a file of a smaller size than the full length gets saved. So if the show is 28Mb I may get 5Mb one day, or 3Mb another day. Doing the same exact thing under Firefox works fine and gets me the full show. Bug or a feature?

content: Re. the issue of different battery life on WAV vs. MP3 - this is almost certainly due to the power taken for memory writes - WAV will be accessing the flash memory a lot more, and this will be where your half hour less battery life in WAV mode comes from.

timestamp: September 28, 2010, 03:01:03 pm
content: Which audio recorded are you talking about?That makes sense but I wouldn't generalise: WAV is uncompressed so should be easier to encode which will take less processing power and could also save power for that reason. It probably varies depending on the recorder.

timestamp: September 28, 2010, 03:47:46 pm
content: Dave was queryiing why the spec for his audio recorder (can't remember model) showed slightly lower battery liife for WAV compared with MP3 and couldn't figure out why - the much higher bandwidth to external memory, and power draw of the memory during write could easily make up the discrepency, even after accounting for MP3 encoding.

content: Yes, it could certainly be the FLASH writes. Although I would have thought there would be some buffering with either WAV or MP3, and that these would pretty much even out in the end.I can't help but think there could have been some power saved using WAV mode if that was (and it should have been) a design spec.Dave.

content: Buffering would not make any difference - it just chages the size of the lumps of data written.For WAV you are writing somethng like ten times as much data as MP3, so the flash device and its internal controller are active for ten times as long.

content: I'm envious that you are taking a trip to Boston, my favourite US city. If I had the chance to move over to the US, it would be around Boston. Kinda European, but very American. At the end of September the New England leaves might just be turning too. I don't envy you that drive though! Great countryside, but it must be over 12 hours drive from Ohio.I think Digikey and Farnell (Premier Farnell Newark) must post their results at around the same time. Our local paper covered the Farnell results (they are based near me); Last quarter's profits are up 47% to £23.8M on a revenue of £252M. Farnell say that is mostly down to increased orders from the electronics design community. As of today, their market capitalisation is £993.99M, which works out at just over $1.5bn. The share tipsters are promoting them, as they see that they have room for growth in pretty much all markets. In the past year or two, Farnell really do seem to have got their act together. Decent prices and the Element 14 community all help. Amazingly, only 1/3 of US orders with them are online! It might be an interesting item for me to write a blog post about. Which reminds me - I have linked to The Amp Hour from my (very new) blog athttp://electronicsdesigner.blogspot.com, hope that is ok.On the subject of US export restrictions - the other day I was looking at one of the new fast ARM based parts, I forget which manufacturer. There was a notice saying that due to government restrictions they wouldn't be able to export them until October! The ARM is designed here in the UK for goodness sakes! I bet it was fabbed in Singapore anyway.Mike
