Try the (RCA D432 CD4051 1BE) I have one here but I'm using it as a 8 channel scope on my "Puter". I wrote my own sotfware for it, works great. ABRA should...
Thanks for our answer for the accelerometer. For the wireless device, I'm going with a computer on the robot so I will use my wireless network or in fact any...
Measuring Distance with an Accelerometer I hope I remember my physics right, I'll try to guide you in finding the distance travelled with an accelerometer. (if...
Wow, thank you very much! Even if I have an art major it is very clear the way you've done it. Then I have to figure out the time between each take, the...
While not wrong, the equation d = Vf*t - 0.5*a*t^2 is stated 'backwards' i.e. working backwards from the final velocity. It is more commonly stated in terms of...
Do not miss canadian tire's special this week. You can get 2 job mate 12 volt drill for 20$ ea plus 10.00$ postal rebate!. It is a steal you do the math! By...
yeah thanks Eric I didn't hear it right the first time. these chips are good indeed just might be what I am looking for to expand my Anolog inputs. with 2...
Just a quick reminder that there's a meeting tomorrow night at 7:00 at Le Faubourg Ste-Catherine. Look for Martin and the racing robot. Wish I could be there,...
Thanks m. Cobb, please can you tell me what do you consider short? Are we talking milliseconds, hundreth or even tenth of a second short enough? Sorry for my...
Bonjour, Voici ce que j'ai fait avec deux moteur de drills. Il reste juste à faire l'assemblage final. http://www.edapi.com/robot/propulsion1.jpg Je suis...
Well 8 ouptuts all in one might be a challenge to find! But when the chip latches what configuration do you want NAND,NOR,AND more questions than answers I...
Bonjour, Le plastic autour de l'engrenage, est seulement pour facilité la manipulation, car lors de la fabrication il est arrivé que l'engrenage se soit...
... have one relay n/c low speed, n/o high speed. then one relay at each motor n/c fwd n/o rev. and one relay on/off. What do you guys think? too power hungry?...
'Short' as defined in ISO 2017 - Definitions of vague and imprecise qualitative descriptions ... Seriously it all comes down to tradeoffs. You need to be able...
Thanks again!!!! Very precise answer. I will check the WCRS group board, always happy to find more sources of information. A+ ... measure ... priority than ......
They got alot of different stuff. Acceptable gears on the cheap! Looking for hard to find parts, Like tank treads? this is the place. This site is specialized...
Please allow me just one last question on this subject. As you know there is 2 axis on this accelerometer. So to find the total distance distance, I will have...
You have to take a closer look. this board also has rs232. Normally (oopic R) you must protect the pins by adding resistors somewhere. it is a very good...
Thier gears are cheap. They sell them for like 50cents ea. That said I orderd a couple a couple years back and the quality is so so. Meaning that the spiral...
I bought a CD4052BE(to be exact) at addisson for 79cents(at Maddison). Cool this will give me 8 extra anolog inputs! My knowledge is not overextensive about...
I was having trouble remembering the multiplexer that I got a couple of years ago, but now I remembered it. It is the CD4067 it multiplexes/demultiplexes 16...
