content: Hello People,Its is a kind of Wired Request but I hope to get a helping hand from your side,I am Starting a Small Company in India With very limited resources at my hands right now.My main Vision is to Convert cheap petrol/Diesel based public transport Vehicles with Electric Public Commute.To Keep the cost low I am Developing Electric Motor and Electrical Controls In House.For my initial Steps I Do need to get my motor Control Solution Up and Running to Show Investors and Interested people to Invest in my venture.As You already know that I am Working on my personal Budget Right Now, So The test Equipments that would be required for them are Out Of my reach.I would be very Delight if Some of you would Mentor and Provide the necessary resources to realize the same.Thank you all.

content: You can take this for what it is worth, but when someone joins the forum and almost immediately asks for a donation of T&M equipment, especially 2 different postings, a lot of the forum members are probably going to question the validity of the plea. I have seen, in the time I have been a member, there have been multiple cases of extreme generosity by members, including paying shipping to different countries. Those who made a compelling enough case at the right time, read by the right member, were not only lucky but very grateful.Granted, some were a little hard on you, but see above paragraph. To make a general statement as to the lack of friendliness when a couple of posters were a little tough, it's not a way to make friends and influence people. Especially when, in 1 post, the title saysrequired. Really? A donation of an oscilloscope is required? I understand that this is an international forum and customs are different in different countries, but good manners are good manners.

Nobody has any cash flow or cash on hand, etc.etc.etc.Seems to me, no matter how passionate a guy is about electronics or whatever, maybe, just maybe, if that guy can't so much as afford the simplest of simple dev boards, that guy should stick with flipping burgers for another year or two before blowing $20 he doesn't have on an electronic trinket...or even asking for somebody else to donate one of those trinkets.WTF...Get a real job.

content: Get a cheaper used analog scope, asking for a free DSO is not going to happen, and older analog scopes can handle what you need.What kind of frequencies do you need to sample and how accurate do the test equipment need to be to control that motor?Even a cheap low frequency USB scope will be able to cope as long as you have a computer, but a run of the mill used analog scope should suffice.But you haven't given any details on what your needs are as far as specs of the scope.

content: The MCU speed shouldn't matter much for motor control, 20KHz rates are easily achievable by any scope out there, even a PC sound card or an Android sound based scope will allow you to see those signals if you use a proper voltage shifter to be on the sound input range.Why 4 channels?You have not give any reason why you need the 1Gs/s sampling rate and the 4 channel requirements and why should it be a DSO?

Just mentioning "tight budget" is not cconvincing at all. Purely out of curiocity, it will be more interesting to see some pictures of what you have done so far.

You say you come for guidance and help-not the same thing as asking for donations from strangers without giving anyone time to get to know you. I hate to say it, but at this point, you might as well have the moderators lock your 2 threads. You have absolutely approached this all wrong and probably don't have a prayer of getting a donation.

content: Quote from: godfather on February 24, 2016, 12:26:42 pmSo let's recap this. You join this forum, not to participate and contribute to the general knowledge base, but to demand free gear to help you start a business venture that you hope to make lots of money at. Then, when you are called out on it, you call people unfriendly. Then you backpedal and apologize that you didn't make yourself clear and didn't understand. Finally, instead of offering a repayment method when you make your fortune, you promise that you will do something for all the people who helped you but you have no idea what that would be.Maybe, instead of coming to a forum where you know no one, and no one knows you, to demand free gear for you to make money off of, you should try to find some local people to help you put a sound business/engineering plan together so that maybe you can find INVESTORS in your business venture.Just to point out, there is another new member who posted a more humble thread asking, not demanding, and making a compelling case (as I mentioned earlier) by asking for hobby use and explaining his circumstances, and is being blessed by another member. So much for unfriendly people here. If I was fortunate enough to have excess gear, between the 2 of you, he would have been the recipient. To keep trying to make your case for free gear to make money in a venture that you don't seem to have an idea what you are doing with vague promises to help those who help you, you are simply flogging a dead horse.

A promise made to people on this forum who live in other countries is vague. How could we fact check to see if you actually do it? NOW you are saying you will offer a motor controller, you didn't when you first said it. Are you going to sell it or charge for it? Giving back to the community implies you will do it for free. Is that the case? If it isn't free, it is not a promise to give back to the community.My apologies on the flogging the dead horse analogy. That is an expression here in the US for someone who keeps at something long after they should have let it go. I love animals also and have two awesome dogs that I love as part of my family.I will repeat myself, at this point you will be better served if you develop a sound business/engineering plan and look for local investors in your venture. Here, you have painted yourself into a corner and have little to no chance of donations to your cause. I wish you luck.

content: Quote from: Aodhan145 on February 26, 2016, 06:12:23 pmI also have concerns about the apparent lack of funding. This does not sound like a serious venture with a well thought out business plan. More like an "I have an idea" project.Asking for a scope is no small request - and even if someone did have one they were willing to give you, the shipping cost is no small thing. Add to that the risks involved in shipping of such equipment and there's no guarantee you'd get it or that it would be intact.Then there are the specifications you requested. Aside from (at a guess) the vast majority of members here not having such equipment at their disposal (let alone on their own bench) you don't seem to know what you need. This doesn't reflect well.The other thing is ... and this is something you do not seem to 'get' ... is that waltzing onto a forum and have yourfirst postsasking for free gear is just - to be blunt - RUDE.

content: If you need equipment for your enterprise, why not start a crowd lending campaign? If your endeavor has technical merit, you'll have a decent chance of finding someone to provide you with the funding you need to buy your oscilloscope.Do a search for crowd lending services that support Indian entrepreneurs. Your case is different than that of the beginner hobbyist, so begging for a scope on this forum is not really a good use of your time.

content: godfather - I am partly involved in EV/HEV development and it is a hard work. Complexity is enormous. It starts with ASIL and ends with cost. I would not start designing even an electric go-cart unless I lived somewhere where are such possibilities (e.g. cheap e-bay shopping).A part of the audience here knows what a 10 kW inverter design really means. The way you communicate seems to be very naive and that is why you got such feedback. We are not here to ruin your dream but I suggest you to concentrate your motivation and passion for something more doable in your country (position). Asking for any free stuff is a no-go.good luck
