    How to Run a Statically Driven LCD display

    Sorry this thread doesnt allow editing of posts. I meant to say is it possible to run the LCD with just an IC/PIC and a shift register? Can the PIC in of itself be the driver? All I need to do is programme the PIC to output two square waves 180 deg outta phase from each other and hook it up to...

    Although in that link its a character lcd and not a CMOS segment lcd like the one om trying to get to work

    How to Run a Statically Driven LCD display

    Thanks will do. As a matter of interest is it possible to just use a shift register to drive the LCD screen without a drive? I refer to the link below: http://blog.hovertop.com/2012/07/driving-a-16x2-lcd-with-shift-register/

    How to Run a Statically Driven LCD display

    Thanks Guys. LiteYear, Ill give your suggestion a try. Jim, thanks for the link. Could you possibly provide me a "step by step" guide in order to make it work? I really don't know where to start.

    How to Run a Statically Driven LCD display

    Hi all, I have attached a 2 page spec sheet on a an LCD display component that I am trying to get to work. I am conforming to its 3V operating voltage by supplying it 3V to the pins. The display only flickers for a second and sometimes not at all. The component itself works and have cross...

    Converting three phase power transmission to single phase power

    Lets for simplicity sake ignore the transformer in the diagram and say we dont want to step up/down, we just want to branch off. Please check the attachment picture below is what I'm talking about. The top part of the pic is the transmission line (with no neutral line) and the bottom part is...

    Converting three phase power transmission to single phase power

    Hi all, I'm not an electrical engineer but a question is itching my brain. How does one convert three phase power to single phase power? (preferably with a diagram attached?) The reason I ask is that the three phase power transmission system is the de facto power transmission system. Also...

    Quotationof Investment Casting

    Hi Ajack, Thank you for your swift response. I did indeed consider a 3D wax print. However, I noticed that some 3D prints normally come with "print Lines" but upon a quick google search I see there are some high quality ones out there, thanks will consider. In this case I would obviously cut...

    Quotationof Investment Casting

    Hi all, Any chance anyone has received quotations or deals with investment casting products? I can only receive limited quotes in my area and want to benchmark against widely accepted costs worldwide for interest. On a high level, the part I wish to cast is a single stage model jet engine...

    Polytropic Efficiency

    Can someone please correct me on my interpretation and explanation of polytropic efficiency, because Saravanamuttoo et al explanations are pretty atrocious. I see it as (applied to compressors, axial, that is): NB Assumption: Every individual stage of an axial flow compressor has the same...

    Energy captured from incoming solar radiation on PV cells

    Thanks Greg that's exactly what I wanted to know. racookpe1978, I multiply by 24 because those values posted in the link are 24hr averaged values. That doesn't mean they averaged it over 6 hours peak. they didn't average it around noon they didnt average it from 6am to 6pm. they took the whole...

    Energy captured from incoming solar radiation on PV cells

    Do you have any of these efficiency relationships? Or is it a safe calculation to simply multiply the 24hr isolation by 24 to get the total energy per area that the PV cell can convert (before efficiency losses of coarse)?

    Energy captured from incoming solar radiation on PV cells

    Hi all. On the following link: http://lightbucket.wordpress.com/2008/02/24/insolation-and-a-solar-panels-true-power-output/ scrolling down a little bit from the top, gives a table of average daily 24hr insolation. Due to it being a 24hr average, to calculate the energy /m2 over a total day we...

    Suspension Design

    Hello all. Thanks for the input, I understand a bit more now. Frustrating that the vehicle dynamics books couldn't put it across more simply. Anyway Ive hit a real dead end here. I do not plan to design the steering knuckle that would be too much work. I plan to take it from existing small...

    Suspension Design

    It seems as though in your last sentence you are saying changing RC does not affect the loads on all four tyres but then say you can shift around load transfer by doing so. Could you clarify this? From what physics and intuition tells me, playing around with how much the load is on the springs...

    Suspension Design

    If those are the downsides off the top of your heads can anyone explain what Milliken means by this paragraph because ive been trying to understand it for ages!

    Suspension Design

    Apart from high tyre scrub, high jacking forces and the inability to tune handling balance, are there any other downsides?

    Suspension Design

    thread108-278309 Old one got locked. Its that time again and I got a couple issues. Can anyone validate my last post showing step by step design process? Is that what you would follow when doing designing suspension? I also cannot for the life of me see what is compromised when the RC is...
