"Thank you! I should probably update the main description (if it's possible in this forum) and put the price in since it is looking more realistic."

"Right, it starts to slide when the thrust goes over 1kg.  Currently I just have holes on the bottom to put screws through but am looking into some sort of clamps that would hold against the edge of the table."

"Exactly, that's what I had in mind when I mentioned the campaign. Actually either Kickstarter or Indiegogo, not sure which is better, but am leaning towards KS."

"Great, I got you as +1 :)
Seriously, I want to get the price down to $99 (+S&H) and for that I need 500+ people. I will start a campaign soon enough and I hope you will commit.
As for delivery first "0 series" batches (meaning first production run…"

"Yes Jani, it looks similar which is exactly my point: "everyone" (or many to be fair) has build one because everyone (actually everyone to be fair :)) who is using electric power needs it. It is just finally the time to have the actual product so…"

"Cao Zeljko,
Izgleda da smo vrsnjaci (dobro ja sam '72) a bavim se avionima I kojekavim letelicama od 9. godine. Drago mi je da smo se ukacili."

"I see. We may have different approaches.
I would like to determine the exact angle X with respect to the starting point (tape in my case) at which the imbalance is located. Then you can put tape to the opposite (X- 180) end and continue doing so…"

"Actually (after some thought), the error would not have to be greater (I just measure time after n pulses, n = number of prop leafs) and even the prop config "hassle" would be fairly easy to solve.
However, the exact reference point would be more…"

Misa Rakic replied to Misa Rakic's discussion Motor Master 5000 - rpm, thrust, power, etc. meter and tester
"Yes, I was contemplating making it that way but was concerned about the reading being dependent on prop config (which can be entered through the setup/pc app/terminal) and possibly less accurate reading (shorter time between pulses, greater err).…"

Misa Rakic replied to Misa Rakic's discussion Motor Master 5000 - rpm, thrust, power, etc. meter and tester
"I decided against the phase reading because you have to enter the right number of poles for each motor, although I should probably put it on the board and have it as an option. I wanted to keep it as easy/simple as possible and IR seemed like a…"

"The problem is MPU not 328p (at this point). I am reading data at 1KHz (max for MPU) and sending to the PC but at 1KHz.

However, teensy 3/3.1 is great so I am still contemplating having version with that. The limiting factor is that I want the…"

"Thank you so much Andre for your kind words and advice, and if I may say so it is a great idea. If you can see next to the motor there is an MPU6050 already in place :)
Actually you can't see it there since I couldn't post so many pictures on this…"

OK, so I finally got sick of testing my motors/esc/props on make-shift test stands. I decided to make something that will be as close to finished product as possible and hopefully, if there is any interest I could make it into an official product.…
