Thats really cool though. If I didn't have high speed internet for more than a day I'd freak out! lol, but I'm always on call because I'm in charge of some medical document encryption servers.
I get to be in New York soon, then in July I will hopefully be somewhere very cold!
I always try to get the best one that isn't super overpriced, that way I can make it last a long time. The 4 core with hyperthreading is great, especially for virtual machines!
I was just browsing the latest copy of an Australian electronics magazine and saw screen shot and half a page about some software I wrote over 12 years ago that I'd almost forgotten about. Now I'm torn between feeling proud and an old fart. It's "GPSDiag" on CNET if anyone wants a Windows program that decodes NMEA output from a GPS for general diagnostics.
One funny thing is that Circuit Cellar also had a screen shot as part of a (possibly paid) review of a GPS receiver years back and it was included on their GPS evaluation CD. The link on the main screen led to the company I ran at the time and we sold different modules that were cheaper. It was always free so no legal problems, but it amused me that someone would put software on a CD that included links to competitor products.
@GarrettFogerlie, I'm about to head off but it's the April edition of siliconchip.com.au but by the looks of it you'll have to pay $8.99 to view and then not get a PDF only use their crappy online viewer. I saw it in the paper version but it's the reason I wouldn't subscribe myself, Circuit Cellar is cheaper / better and has PDFs you can search on.
You not keeping me up. But my tablet is pissing me off, every time I type it zooms the site so I can't see anything. Ugh. But there are lots Of ways, just Google "Linux echo to begining of file"
I'll catch you guys later, my tablet's being a pain! Goodnight.
This is basically a tachometer. Depending on the pulse size, gain of 1000 may be enough. If so ac couple to a Buffered Cmos Nor,Nand or inverter gate with 1 to 10 MOhm feedback and 1000 pF or so to drive the date from Vcc or add a small series resistor if necessary on power to create the pulses l...
I don't think the user wants a pulse to V converter. Rather, I suspect that you can run the pulses directly into an Arduino timer/compare/whatever module. I am not familiar with the AVR's specifically, but many timer modules in MCU's will take an external pulse/clock in and measure the period of that signal.
@DavidKessner Well, it seems like OP needs some way of getting that windspeed into the Arduino. The AVR chips I know don't have a "measure" function like that AFAIK, though I think Arduino code might. It seems like some sort of RC timer circuit to convert the pulses to voltage that could be read with ADCs will be difficult here, because (I would guess) the duty cycle remains constant regardless of wind speed.
@angelatlarge if you look at what I responded to you can see. There is an arrrow on the left side of the message that if you click it will highlight what I responded to.
@DavidKessner I would, but just one question: I thought you guys (ye olde timers-e on this-e forum-e) decide to keep the answers that were relatively on-topic, no? Didn't I see that in the chat somewhere, or did I invent that like over-current protection on AVR chips?
We tried to let him stay and see if he would play nice. It didn't last. But I do not make official policy.
@angelatlarge If he were smart, he'd make some puppet accounts for the sole purpose of up-voting his other accounts. Fortunately he's not smart, just tenacious.
@angelatlarge Once upon a time he might have been a good engineer. He has given good answers in the past. Unfortunately he has also given some really terrible answers and when he's called out on it he basically throws a temper tantrum.
@angelatlarge I haven't seen that one specifically, but I have seen similar things. TS indeed has become that-- but with a bad attitude, unlimited time, and a mental problem (I am not a Dr.).

Unfortunately, I don't own a programmer that can do JTAG in circuit debugging stuff, I've just been using a usbtiny programmer. Maybe in-circuit debuggin would help find such faults fastser, this might be my impetus to get one.
@angelatlarge Everyone down-voted him. But they should flag it as spam instead. If enough people flag it, the post gets automatically deleted without moderator intervention. I forget if it is 3 or 5 flags.
