Who has this bot? What do you think. I just built a self balancing one from a kit and have it 90% stable but it needs a lot of work.
Lets here your comments about the MiP.
Eric
It is late and I am very tired. If this is obvious I’m not getting it. For the life of me I can’t decipher the pin out to sd card / spi on the breakout. From the upper left (card goes in in the right) they are labeled
D2 D3 CMD CD CLK VCC GND D0 D1 WP
I want to hook this up to a spi bus device (mbed) and I get the VCC, GND, CLK but which ones are:
SPI mosi SPI miso CS
I have the same question
It is so nice to hear about a company operating in a common sense and generous manner. Well Done!
So this is pair programming!
I’m wondering if anyone has and knowledge of the light ramp and decay times. So when we apply a specific current, how long does it take for the light output to reach maximum? And then when the current is removed, how long for it to fall off?
Not directly. You will need to use a switching power transistor that can handle at least one amp. The arduinos handle like 40ma per I/O pin (for the uno at least). I’m not an expert in this so please consult others. But using a mosfet transistor is the way to go. Then you use the arduino to turn the led on and off through the switching transistor. This may help. http://www.youtube.com/watch?v=Te5YYVZiOKs
I bought one for my daughters and I for Christmas. Unfortunately, my wife thinks we need to wait till Christmas to start assembling it. So we will. I’m excited and my daughters will be when they find out.
I’m thinbking about power consumption. So if I put say 10 of these together that gives me 10x80 LEDs possible. If I turn on all 80 LEDs are they really all on at the same time? How do I manage power consumption? Sorry I’m pretty new to all of this.
Okay guys, can we stop this moldable plastic experiment now?
No public wish lists :(
