    Microwave oven leak

    The .gov website you posted earlier was only reaffirming my points thus far. :/ Bees are dying because of things. Honey Bee Die-Off Caused By Multiple Factors Including Pesticides | News & Notes, What Matters Today | BillMoyers.com I don't really like it when people start trying to fight...

    I didn't mean to ask you something that might infringe on your design security! I'm a bit too curious sometimes. :)

    Microwave oven leak

    Laserbeak, I think there is a very large difference in what we consider evidence. When I think of evidence, I don't tend to lean towards something the media reports. The media above many other mediums tend to be biased one way or another, depending on what "sells" better. Surely you've...

    Not smarter - just educated further. Education doesn't make you smarter. :p Europe tends to ban anything and everything that hints at risk of anything. The big "C" word tends to scare the crap out of people - and politicians can use that to their advantage. Just sayin', the US and Europe alike...

    Dark Sensing Circuit help

    Assuming that Vds is too low, then yes. In the case of the IRFP260, all you need is 3V to turn the thing on. So putting 5V on the gate and 5V on the drain will enable saturation. (5 > 3) && (5 > (5-3)) = Saturation Once the RC circuit slews down past 3V again, cutoff will take place. (I...

    La Spada Verdi: 1st Ever 520nm 115mW MS-SSW; Build/Review; Very Pic Heavy

    Re: Coming Soon! MS-SSW with 300mA PL520! I thought 300mA was a weeeeeee bit high for these diodes? IIRC 200mA max on the datasheet is the rating.. maybe you already knew that. :D Good luck with your new build!

    Microwave oven leak

    Not to stomp on your microwave dangers parade here... but I often find that everyone else I know that is even concerned about the idea, also "Don't know nuthin' about frequencies and such". And then those that come out of a basic undergrad physics course or two have zero concerns. I hope you...

    DTR are a exellent seller!

    We sometimes take guys like Jordan for granted. He is one of the few guys who does things right, and does it consistently. The day this forum loses him is a very bad day.

    I could poke around the "Signals and Systems" lab at Uni - is someone looking for one?

    your opinion

    I don't know man. Putting goggles on instantly lets me point at any mirror or shiny object. I agree though, that if you've got a nice white wall to point at from a few meters away - no harm done. If you step things up to ~500mws of 532... well its not as comfortable anymore. Hell, even 30mws of...

    Microwave oven leak

    Wiki says that IEEE protocol 802.11 works off of the following frequencies: 2.4 GHz, 3.6 GHz and 4.9/5.0 GHz bands. I believe additional bands were added because of the interference caused by wireless handsets and microwaves. The faraday cage on the microwave will probably be built only for...

    Dark Sensing Circuit help

    You should probably also add an RC circuit with a small time constant to the gate of the FET to avoide very abrupt switches/ lets the gate "ramp up" to HIGH state and prevent sudden (sub microsecond) voltage fluctuations. But get the basic circuit working first. :) This will work with any...

    Dark Sensing Circuit help

    Fixed. There's a way around it. You're not a trollin' newbie, I know that. Start with something like this basic circuit: It uses a voltage divider, whose output is dependent on incident light - right? Cool, now take an op - amp or a comparator and take that varying voltage, and compare...

    Ok, yeah...but why?

    Nah don't even worry about that. The theory is great to have when you save time and money in the end by building a working device, rather than building a device and then spend time trying to get it to work. It should come to you easily since you have the advantage of hands on experience. Its...

    Dark Sensing Circuit help

    Get some measurements of current through the photocell branch, and some measurements of base voltage. Do this for varying stages of incident light. As an alternative, you can take a small microcontroller like an AVRtiny to read the photocell and switch a GPIO in response. It would be very...

    Brian, If you run into any hiccups along the way, don't be afraid to just ask. This place doubles as a great way to begin learning about electronics, and anything electrical question is relevant to interest of the forum. You can always PM me or some other members who are willing to help -...
