update ,little bit of progress

on the batcave /milking shed front .
i now have a fully wired cave/shed.. lights on proper switches! sockets everywhere ! remote switches on ex extraction cooling fan and compressor !! .most exciting , now i just have to connect it all to the house,meter box and stand back and flick the switch..hopefully not to be met with a kaboom.
software wise ..
well ,sophie has achieved a lot ,with graph pages and menu's and everyfink ,very encouraging .apparently the csv 'coma seperated v' thing in c hash language actually realy means use a ; not a , so after that little trap was understood it went swimmingly .(i have probably got this totally wrong ,and im sure ill be set straight lol)

im hoping to do some actual dyno running next week ,and get used to it all again .
better start saving for an mbed doofah .:-)

HIGH EXCITEMENT ENSUES (plus a little trepedation .)

MBED Board Genesis

Started putting together schematics for mbed board today, emailed 'the team' to check going in the right direction before going off at too much of a tangent.

quick test

to see if the email thing works .go about yuor business as usual.

april 15th update

presently , we have the sophmiester plotting and byting away at her hot software package ,somewhere on planet earth ,maybe england .

,and way down in the south of england ,we have andy ,getting mbedy wiv it and creating a hardware assembly for the connections of probes and various voltages .


i did an experiment ,

http://www.youtube.com/watch?v=6h1keH-u22Q

and found that the rr makes a 10 v signal at maximum power ,and the same 10v max for the speed signal . i know i can vary these maximums ,and at present i imagine getting a 80 tooth wheel made for the speed instead of the 100 tooth wheel , this will bring max speed up to 155mph from 120 mph .and the power i can choose a level in calibrating the machine , so will choose 480 bhp ,this plus a normal sort of losses figure at 150 mph would give approximately 480 + 40 so 520 bhp max .hmmmm.. yummy.


i also found out thanks to andy's huge cerebellliumniummnum..um, that the signal conditioning board takes that 10v max and brings it down to 1.7v approx . so the ad board in my old pc could digest it without having a fit of the bots .

also it does look like ,when doing the run down and measuring the losses , that 10v max goes negative ,and that negative voltage gets added to the max bhp to make the power be at the crankshaft , not at the wheels .

i had a chat with sophie about the formulas for correcting power figures to an industry standard ,and she replied in the positive . :)



so chassis dyno testing facility wise ,i think i may be on the home straight, i got the pipes laid in for the air feed to the dyno to lift cars in and out ,and lock the rollers .

also the pipe for draining the dyno pit if it get flooded .

i have the whole air line system in as well ,and tested it and it does not leak ,oh yes! .or ,um ..no , in this case .trying to force feed a garage roof 20 feet of steel gas pipe for the air feed on my own was fun ..pleased im not a vet !!or a nurse !!!

i tested the compressor silencing box , but i found it was still a bit too obtrusive , i tried both compressors in there ,and the blue one from aldi was definately better . so a bit of block laying and mortar is on at some point to silence it a little more effectively .

also got the steel tread plates made for the hole down the side of the machine ,all cut to size for a tenner !! noice .


next jobs ,are ,put in power feed from house to batcave ..paint the machine , paint the floor ,and buy some 16 inch diameter flexible pipe for the air inlet ducting to the front of the car ....


oh HOLD ON ..i just realized ,i also have made the 4 inch thick soundproofed air outlet duct ,4 ft by 5ft tapered design ,and a hinged flap in the outer wall for the air to get out .and also sprayed expanding foam around all the frames and trimmed it back ,,, oh blimey ,also made a wooden frame on the floor for the doors to seal up against .wooof .... i go waffling along thinking i have'nt got much done ,and then stuff me with bitter lemon slices and call me madeleine !!! all this stuff gets done somehow .MARVELOUS.

update , big things afoot .

hello fellow bhp obsessives ,

well after a fit of comunication with the think tank of sophie and andy ,me playing the part of the country yokel to thier enstienosityism ,a plan seems to be forming .

sophie has gone totally programtastic and is all up in the hood with c++ which gets a a++ from me !!

andy has had the collosall brain wave of using the mbed development board thingy ,which , it appears ,has a ad part with 8 channels ,and cheapest iv found so far is i think 38 quid from fernall.the great thing about this is its a piece of kit s and a are familiar with after using it on the trionic .

andy had had a look at the signal conditioning board on my pc ,and its a buffer attenuator ,,,,er,,,, so i guess dampens down spikes ,and changes the volts a bit .(incompetant r icon ).

i have been a bit ill these last few days , but managed to get a bit of stuff done in the batcave yesterday ,built a 3/4 inch panel for the rhs fixed door, and insulated and fixed it up ,so that side is sealed and quiet .used about 900 pieces of ply to do it ,but got rid of old wood and it looks ok .specially when i paint it all.

even more encouraging , sophie sent me a link to the tat software ,asking if that was desirable , ooof !a big old affermative good buddy ,was my response ;) although thats probably ages in the future if its possible at all . not going to assess my livefowl previous to their inception :)

its all jolly exciting !!!!

This is done by an analogue-to-digital (A/D) converter.An A/D converter can only digitise one signal at a time. Some data acquisition systems provide an A/D converter for each analogue input. However, it is more common to switch (multiplex) the signals in turn to one converter. This method is used in lower cost systems like the 750.Settling Time and Cross-Talk============================As the multiplexer switch one input after another to the A/D converter, you must allow time for each reading to settle to its new value. This settling time defines the minimum interval between reading each input. If you try to go faster than this there will be increasing cross-talk between channels, leading to inaccurate results. Cross-talk is when one channel's signal causes an undesired effect on anotherLogging Data from only Some of the Connected Inputs===================================================For test applications you may want to read from some inputs in one test run and from a completely different set of inputs in another. You obviously don't want to slow down the system by reading all channels every time. Software like Windmill avoids this by letting you select as sub-set to scan for each test. This avoids the need to rewire your connections each time you want to record some data.You can find out more on multiplexing at http://www.windmill.co.uk/multiplexing.html________________________________________________________________________________________________________________Excel Corner: Setting the interval between data readings________________________________________________________You can use Windmill Logger to regularly collect data and store it in files; periodically starting a new file for long-term logging. Once Logger has closed a file you can open it in Excel.There are some situations though, when you will want to use Excel to regularly capture data from instruments and devices. To do this you need to use a macro. A typical data collection macro is given at http://www.windmill.co.uk/excel.html#ExcelWhen taking readings at regular intervals which are controlled by Excel, the macro must pause for a while before taking the next reading. There are several ways to do this, the most often used being Wait or Sleep. These are detailed below, but both have the disadvantage of tying up Excel whilst the macro pauses. There is a way round this: by logging only when new data arrives. See below for details.Using The Wait Method=====================The Wait method pauses a running macro until a specified time. For exampleApplication.Wait(Now + TimeValue("0:00:10")) would wait for 10 seconds.Using Wait has a couple of disadvantages.1. The minimum Wait time is 1 second, so sampling rates of less than one sample per second would not be possible.2. The Wait method suspends all Microsoft Excel activity and may prevent you from performing other operations on your computer while Wait is in effect. However, background processes such as printing and recalculation continue.Using the Sleep Function========================Before your macro you need this declaration statement:Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long) This is because Sleep is a Windows API - application program interface - which is available from the Windows operating system.In your macro, to sleep for 10 seconds, useSleep 10000(Sleep is measured in milliseconds.)Disadvantages of using Sleep1. Again, Excel activity will be suspended for the duration of the Sleep.Logging only when New Data Arrives==================================This method lets the Windmill DDE Panel control the timing, rather than Excel. It only runs the data collection macro when new data is available from your instrument.1. In Windmill DDE Panel select the Copy to Clipboard button and copy data from All Channels. 2. From Excel's Edit menu choose Paste Special and "Paste as Links" into the first row of a worksheet called "Sheet1". 3. Create the code given below and run MonitorDDE. The MonitorData routine monitors cells which are showing live data via DDE. When values change, it calls the LogData procedure which progressively writes the readings into new rows in the worksheet. You will need to change the channel name from "My_Channel" to match your data channel, as the DDE Panel displays it.Dim NoOfRows As IntegerSub MonitorData()NoOfRows = 2' Monitors the DDE links for updates' When data is updated runs the subroutine LogDataActiveWorkbook.SetLinkOnData "WindmillData!My_Channel", "LogData"End SubSub LogData()NoOfRows = NoOfRows + 1Column = 1'Initiates conversation with Windmill DDE Panelddechan = DDEInitiate("Windmill", "Data")'Requests data from "My_Channel" and stores it in'memory under mydata.mydata = DDERequest(ddechan, "My_Channel")'Inserts data into the first column of Sheet1Sheets("Sheet1").Cells(NoOfRows, Column).Value = mydata'Ends DDE conversationDDETerminate (ddechan)End SubFurther Reading: Using Excel for Data Acquisitionhttp://www.windmill.co.uk/excel.html_______________________________________________________________________________

grande designe!

well ,instead of a fit of decompiling and modifying ,and generally doing things the hard way ,one of my partners in crime 'simply4rElaxation';),has suggested ,hey , why not just do a whole new software starting from scratch !!!er , um ,well ,because im totally incompetant ? notwithstanding this ,sophie asked me ,what would i like in my software .resisting the customary douoooooble entende , i said hmmm ... 2 boosts, 2 temps ,rpm, bhp, (torque can be derived from bhp and rpm ) then i had another think and realized , that ,once again , im thinking too small .if there are 16 channels on my ad board ,and genarally on most boards available at least 16 ,then why not use them ? so i wondered if a add on type of function would work ,where a channel can sit there unused ,and then be allocated a sensor and calibrated in the program ? one other part of a program needs to be ,a function where one can link the speed of the rollers to a rpm of the engine , in the program . eg in my old software , it was hold engine at 60 mph ,and put the rpm in a box on the screen ,this tells the softw whats what . also ,the sw has to know when to start the run ,in my old sw you pressed a button to start the run ,and it would start recording once the bhp got over a very low level .it would then continue to take a measurement until it got to below that level .in this case , the dyno measures power on the way up the rev range ,then you put the car in neutral ,and let it coast down ,and it takes a continuous measurement of the losses in the transmission,and adds these to the power up run ,to give total power at the flywheel . so this isnt a woo hoo look what ive achieved post , its a current thinking sort of a post kind of thingy. regards robert

hmmmmm....

maybe worth an investigate !!:)

decompiling and dissasembling

http://www.simtel.net/category/Disassemblers-Convert-executables-to-ASM/73.html

i found this mine of interesting software ,no idea what im doing but it looks interesting .

questions to be answered so far are

whats the difference between decompile and dissasemble?
can one do one of these to my present software and then modify it to be better ?
does it then need to be compiled to a language the pc understands ...machine code ?

i know a person on a forum did rewrite the software and make it print better once .

to be continued .

r

nice graph of my mini on 12 psi , this is the win dyn software by superflow 9800 pounds to use this !!

this is the dynocom software ,my mini on 19 psi . i think this is as good if not better than win dyn .

heres a graph from my original software ,my honda 400/4 on 15 psi ,bit hatchy ! not really a patch on the others .;(

gettin softy wiv it ..

hello everyone , first post on this blog , the subject for consideration on here , is dyno software .

i have a sun (maha) ram 12 chassis dyno ,its software is a little oldm ok ok ,gross exageration , it came out in two's from the ark ,but it works , just not very prettily .

i'm hoping that with a bit of effort i can find a way ot have a pretty analytical software ,that loks good and impresses .i'll put some examples of its graphs and things on here ,and put my progress down as well .

regards
robert .
