- This is Part 3 of the DIY (Do It Yourself) Dyno project. This video will introduce you to the software SimpleDyno that is used and walk you through the initial setup. Installation instructions:
1. Download the zip file from my link to the Download folder.
2. Then right click on the zip file and selected Extract All. A new folder will be created called "SimpleDyno 6.5.1 Release Package" in your Download folder.
3. Open the new folder and double click on "SimpleDyno.exe" it should work on Windows 10
You can copy the folder to your Documents folder and it will work there. Right Click on "SimpleDyno.exe", Create Shortcut and drag the new Shortcut to your desktop.
If you install it in the Programs folder (where theoretically it should be installed) you may have Win 10 permission errors since it isn't installed using the Windows mechanisms.
The pdf manual/instructions are in the "SimpleDyno 6.5.1 Release Package" folder. When you run Simpledyno, it will create the C:\Simpledyno folder, there are initialization files that you can open and modify with Notepad. SimpleDynosettings.sds and defaultview.sdi.

Дядьку, велике дякую за ссилку на програму, вдачі вам в розвитку каналу.
Ласкаво просимо
Very informative videos! Thanks for spending your time to make them to help us out. I have a hydraulic brake dyno. Can the software be converted to be used pounds of pressure instead of sizes and weights of a flywheel? Hope you can help me out! Thank you.
If you can calculate the moment of inertia for hydraulic brake then you can manually enter in the data - fudge it?
Great presentation, I love it. I can't seem to find the upload , like it's been taken down . Is there any way to get a copy from you. Thanks
Try now
@@blanchae thank you so much. Thank you.
I am interested in using an Arduino; however, I only have the "audio only" in the pull down and not "audio and COM port sensing option". Has this functionality been removed?
You must hit the "COM" button first then it will show up. Just double-checked it. I haven't used an Arduino with it. When I first turned it on, there was no option as you indicated. When I hit the COM button, the option appeared.
Hi I would like to build my own dyno for RC’s car motors but none of the simpledyno download links work, can you advise where I can get it or a similar alternative? Thanks
There's a link in the video description
@@blanchae thanks I have it now, liked the videos very much
Is it possible to remove a gauge? I can’t figure out how.
I didn't know off-hand but figured it out. Simple but not intuitive at all: double click on the gauge you don't want.
hi i been trying to find simpledyno software but it all seems to lead to dead end sites. do you still have the complete file set you could share?
The links are in the video description, select "Show More"
Nice presentation, cant find the link to the program download Thanks
In the description
At 6:50 you explain the dimensions and masses of your rotor, and as long as I can follow you, you got the whole theory of how a dyno works wrong. In your case, the "roller" has to be encountered, but you misunderstand, that, in your case and in the big scheme, the "roller" is insignificant. The reason is, that the vast part of your total roller weight in in the 2 brake rotors... To use a dyno, you have to know the exact distibution of the weight along the different radiae of the roller. In your case, it´s easy to calculate that for the "roller", but for the 2 brake rotors, that are far more significant, it´s almost impossible. The reason: Their mass is too complicated distibuted along their different radiae, which is the least you should know, in order to calculete the mass of inertia...
What you need, is a "roller" that has the form-attributes of the roller shown in the picture, with following KNOWN data: the inner and outer diameter of the roller, the diameter of the schaft, the inner and outer diameter of the end-caps, and the lenghts and masses of roller, shaft and end-caps. In other words, to calculate the MOI, you have to know where in space each nanopicogramm of mass is distibuted. But this programm will calculate it for you, if you feed it with the correct data.
The reason is simple: an 1-inch-shaft of 10 pounds (2 feet long maybe?) turning at 100rpm has other/different/lower inertia than an 1-inch-thick disc (of same material and weight) of 1 foot diameter turning at 100rpm. Also, calculating the MOI of porous, randomly hollow or rusted materials is impossible, cause none can tell where the hollow points are, or where the rust is, that has a different density than unrusted metal !!!
Your roller can be long (as in the picture), or short, it only matters that it has the form-attributes of the one in the picture: A material of known and homogenously distributed density, an outer shell of known dimensions ("roller"). A shaft of known dimensions. 2 end-caps of known dimensions. If those parts consist of different materials, then it also has to be known (for example: the shaft is steel, the 2 end-caps are 20 plastic CDs stuck together, and the "roller" simply doesn´t even exist). For small motors, glueing CDs together is the simplest method, but thats for rc-model-motors. the easiest is, to find a massive cylinder, and stuck/weld 2 short shafts in the center of the cylinder´s ends.
Thanks for your in-depth comment. This is a learning experience for me and I'm trying to use roller style software DynoSim as a direct connection dyno. In Part 5, I actually measure the Moment of Inertia of the rotors and go through the calculations as you explained. In Part 6 Gear Ratios, I explore the effect of gear ratios to the Moment of Inertia. In an upcoming Part 7, I hope to have it all figured out.
@@blanchae As long as your dyno-weight has the simple form shown in SimpleDyno´s picture, or a variation of it (in a massive cylinder you have only 1 roller and a shaft eventually, but no end-caps), Simple dyno is gonna calculate the MOI, but if more complicated, you´d have to calculate it yourself (a sphere with shaft, or a rhombus with shaft, or any other form that deviates from the basic one in the picture), and the MOI of a brake-rotor would take you a couple of days to calculate (every single airation-hole has to be "weighted" for its exact position and for containing air instead of steel ;-), so, sure, but not worth it. There is surely programms, which would use a 3D-CAD-Model of a brake-rotor, in order to calculate its MOI, but still, you´d have to trasfer your rotor-form from reality to a CAD-Programm. Doing it by hand is a lot of work, maybe stereolithography (take many pics, feed them to stereolithography-programm, let it make 3D-Model for you) can assist, but still you´d have to finish the details by hand, and check everything yourself anyway (meaning, also the stuff/dimensions that the SLG-proggi has supposedly already finished by itself).

You are the man! !! I made my own Dyno. Can I talk to you somehow? Do You have Whatsapp?
Don't have Whatsapp. My email is in my channel "About"
