Hello all, Does anyone know what is the best way to variably control a 12v electro magnet through a bx24? I need to be able to smoothly change its power and...

Hey, I'm trying to interface a BasicX to a MaxSonarEZ1<http://www.maxbotix.com/uploads/LV-MaxSonar-EZ1-Datasheet.pdf>, and have been running into a rather...
Hi, I'm trying to use a button, and I am completely confused. When the button is pressed (closed), I want pin 11 to go HIGH. Here is my current code: Option...
Change your code to if(GetPin(12) = 0) Then Your switch should connect between pin 12 and ground. By assigning it to bxInputPullup, it will show high unless...
Add the following line after your call putpin =(11,1) : else call putpin(11,0) end if. What you are doing is setting pin 11 high, but not setting it to low if ...
Thanks for your help. Pullup is what is confusing me, i think. When the switch is closed, 5V flows through it. When the switch is closed, I want Pin 11 to...
The pullup is only programmed for INPUTS i.e switches and sensors. A pullup is an internally programmable rsistor ( inside the BX) that is connected to +5 when...
I was trying to program it, and the dev. kit was powered by 12 volts. The BX24 got hot, I let it cool for 6 hours (it cooled in like 5 minutes, tho) and now it...
I think I get it now. My BX24 was damaged somehow, so the replacement is coming... In the meantime, I eventually want to be able to fire a nichrome wire from...
... "force" of the battery... That might be a great spot for an SCR, in the low side of the nichrome load. A signal on its gate will latch it on until the...
I know a bit about electronics, but not everything... what's an SCR and ISTM? Thanks! ... -- Ian [Non-text portions of this message have been removed]...
... Sorry. It Seems To Me. An SCR, a Silicon Controlled Rectifier or Thyristor, is a three-terminal diode that, once conducting, normally stays on until no...
The nichrome will actually set off a small pyrotechnic charge (this is for a rocketry altimeter), which releases the parachute. Once the pyrotechnic charge...
Putting your name and nichrome wire together suggests you are launching rockets with the BX. From a safety standpoint, I would stay away from SCRs. You could...
Actually, when the nichrome wire heats, it heats instantly (it basically melts). Also, the nichrome will only be fired at apogee (the highest point of the...
... Probably, yes. I suspect most any small SCR will be fine if it can handle the open-circuit supply voltage, the on current, and the gate voltage and...
By the sounds of the application an untimely firing wouldn't really endanger anybody so it isn't much of an issue. However, from an explosives standpoint (my...
Here is one from Digikey: http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=IRF510-ND They are available from most suppliers. Your application...
That would be good, but do any companies offer one with free samples (I don't want to pay digikey $10 in shipping and handling for a $1 part)? Thanks ... -- ...
I am not sure where to find a sample but Radio Shack (Ugh) has a IRF510 MOSFET. However, it is only good for 3 amps but I suspect it will still work for your...

Hello I am using a RF Transmitter/Receiver pair from here: http://www.sparkfun.com/commerce/product_info.php?products_id=7813 I wrote this code in the BX24 to...
FWIW: Your code look good to me. Try changing your transmitter voltage to 5volts. When you run it at 12volts, then the 5volt input may not be high enough to...
It looks like the ADIS16251 is available today. The packaging is a 20 terminal stacked LGA type (see link). Does anyone know where I can find a socket for it?...
I am trying to see if I can read the Sony PS2 Controller with the BX- 01, but need to figure out the right way to replace shiftIn and shiftOut. I am working...
I have been using the BXDS w/BX-01 alone, but I have the RAM sandwich and LCD. I haven't used them yet, because it seems like I will lose the use of many of...
