    Do any of you use Linux? If so, which distribution?

    There is Raspberry Pi Pixel OS Beta (Debian Jessie based) for x86 Pc and Mac, I have be using it on old hardware and it flys granted its only on a USB stick ATM. I use Ubuntu 14.04 with a ThinLinc server on an old Quad core, like Ms terminal service except Free for upto 10 users. I also use...

    Mylar sheet, 1 sq foot charged to 20 KV, clap to discharge

    Lets say I have average hands with slightly longer fingers but skinner. I used 1st result in Google "Surface area of hand" so no I only used one plate. Calculation well Googled across 2 OS ..copy and past has a problem from Raspberry Pi Pixel OS to Ubuntu Thinlinc Server so cant post all the...

    Mylar sheet, 1 sq foot charged to 20 KV, clap to discharge

    Please delete if not allowed. The teacher charged a 1 square foot sheet of mylar sheet up to approx DC 20 kv one day long ago in school via an modified EHT output of a TV. I had one of my mates hold it by the corners in line with my hands, I then judged and guessed and clapped it with both...

    Is it possible to deflect or modulate a FM Transmission?

    Can I take a week or so to create my forum then you might have a better idea of what I am talking about?

    Is it possible to deflect or modulate a FM Transmission?

    Thanks for the reply. Its just some thing I need to know is possible. For example if you superimposed the FM transmission on the audio output would the speaker act in some small way as small antenna? "A Cosmic Radio Transmitter"?. Turns Audio into a beam of light. A modified/hardwired into a...

    Is it possible to deflect or modulate a FM Transmission?

    Can you use a speaker to influence a FM analogue radio transmission no matter how small? The speaker and antenna where about 2 m apart. The PC has an audio AMP added in of 20 W. see Drawing not to scale.

    Involves Slot Cars , Transformers and 2 cars on each track

    Ok What happens if you put the 2 cars back to back on the track with the same people using the controllers?

    Involves Slot Cars , Transformers and 2 cars on each track

    Yes Many thanks, also if you fit a Capacitor in as well to smooth the half wave current on the motor out it works a bit better.

    Involves Slot Cars , Transformers and 2 cars on each track

    I had a new slot car race track with step down transformer given to me by my Grand Parents for a birthday present. One thing I did notice, is the car with the lowest internal resistance motor used to go faster, well that's what my Dad told me at the time. I found this to be very true on a...

    Problems recording sound on the computer

    I think you need to hunt for an Electret Microphone if you wish to us your pc card as a recording device. I you can't buy one, get a cheap or deceased telephone answering machine that you can record your own message to wire up and test the quality side...

    Whats the rule for a Secondary of a transformer VS Rectification metho

    Could I assume if I had a Full Wave Center Tap Bridge and loaded the windings 180 ° out of phase I may be able to draw I D.C = 1.27 x Sec. I A.C ?

    Whats the rule for a Secondary of a transformer VS Rectification metho

    I seem to remember my lecturer talking about Transformers and Rectification methods and there ratings for different modes of operation (25 Years ago). I bought a book called Understanding DC Power Supplies By Barry Davies and I cant find any reference to my question in it. The question is...

    Is reducing an engines fuel consumption by 85% impossible?

    I expect to be shot down in flames but I don't mine one bit. I have just done a bit of a drive in my 28 year old Nissan Bluebird Wagon about 10% city 90% HWY....NO Fancy EFI systems or direct injection here just a plain old carburetor running slightly rich at idle. I just did a rough...

    Is this a good rule of thumb for engine exhaust temperature

    My header's have no coatings as far as I know. My method involves raising the compression to about what todays engines are running. You could say I have made minor changes to the inlet port but thats all I am saying, But the information is on the net of what I have been up to..But the pics...

    Ruben-Chladni plate

    Dont know if you are trying to do something like this its a fairly new video it has rods strung under tension and then they are plucked by a sawtooth disk driven by differet motors. I am not really sure but the chladni plate looks to show the resonates in the plate its self not the standing...

    Frequency to period adjustment in program loop calculation

    incdelay: tid# = tid# + .02 id& = 1 / ((1 / tid#) * (1 / 2000)) RETURN Ok so Ive been working on it here is one solution I ran a few points in the program then adjusted the loop when 265 was calculated to read 100 Hz then took the difference 256 - 200 = 56 so thats the offset...

    Frequency to period adjustment in program loop calculation

    Homework Statement Adjust a program loop so frequency will change linearly with a keyboard increment or decrement. The current calculation adjusts about 40 counts in the delay loop but when the frequency gets high the step is frequency is very large with each decrement in the loop. A...

    My internal combustion engine is more efficent than 30%

    Thermocouples Ok but I would have to get a hole drilled and a fitting welded to my exhaust. An engine under load is whats needed. "what do you mean by 'extractors'?" They are smooth mandrill bent tubing providing a rounded flow for the exhaust gasses also usually larger than cast iron...

    My internal combustion engine is more efficent than 30%

    Would exhaust manifold temperature tell how efficient an engine was? My engine which has a cast manifold and I have a normal engine but its got extractors. Problem.. Can I compare the two? Test setup: My engine temperature was about 95 deg C and warmed up and idling, the ambient...

    My internal combustion engine is more efficent than 30%

    ok Change of subject Gensets and there fuel consumption. Rough figures 2.5 kva 5.5 HP 163 cc engine at 3600 rpm with 2kw load 15 L will last 6.5 Hours So that is 38.46 cc/min with approx 2.4kw output (80% generator efficiency??). The turbocalc program calculates fuel for 2.4kw at...

    My internal combustion engine is more efficent than 30%

    "The ultimate proof is in the pudding" ok done a rough estimate if I could drive fairly constantly with out too many hills at 60km/h I could do it Atlanta to New York 1418 km if I had a 20 L jerry can on board. It begs the question I will use overdrive on my next test to see if it is any better...

    My internal combustion engine is more efficent than 30%

    Thanks for the tips I don't repeat a test until I have made an improvement. When this condition is false I will repeat a test. Buy, rent, or borrow and steal... I wont be able to afford to fuel to run my engine for 4 months at the moment so I will have to work on something else until then...

    Does the Carnot heat engine law apply to an internal combustion engine?

    I calculated it from the ADR rules the city mileage test the dyno setting is 6.7kw at 80 km/h and a dynamic load for acceleration which I ignored then assumed a 30% increase for drivetrain losses. I worked out my average speed then then calculated the load for 40.95 km/h. I know my methods are...

    My internal combustion engine is more efficent than 30%

    Thanks for the input I have been working through the data and learning you are right I do not know much about the theory and most of the time I haven't a clue what is going on but I can now say I have shifted or moved the slope of the line for load vs efficiency. I now don't think I have a...

    Does the Carnot heat engine law apply to an internal combustion engine?

    Im learning slowly... I compared the fuel consumption of a normal engine and my engine using the fuel required for no load and the fuel required for load and compared the thermal efficiency of the power stroke only. Normal engine output 4.334 kw 1730 rpm consumes approx 96.24 cc/min I...

    Does the Carnot heat engine law apply to an internal combustion engine?

    I do have data but its a little shaky and no proof. My car when engine was new and when driven at 80km/h in overdrive 4.18 L/100km. My EFI car when driven at 80km/h in overdrive 6.33 L/100km My next job is to work out the trip travel times and the estimate cc/min and measure rpm.

    Does the Carnot heat engine law apply to an internal combustion engine?

    What is the indicated thermal efficiency of an engine? Fuel used in total 42.61 cc/min @ 1730 rpm. Fuel used to get to 1730 rpm = 29.16 cc/min no load. Fuel left = 13.45 cc/min to do approx 4.335 kw at 1730 rpm approx 40.95 kph Fuel heat content 34.8 kj/l Approx 62kj / kw...
