Product COM-11102 | about 3 months ago

My Chinese isn’t that good but it looks like the shaft diameter is .20". Is that correct? I’d like to use these to attache to the back of my stepper motor shafts on my CNC machine to use as a DRO (Digital Read Out) of the current position. They seem like they would be accurate for this purpose with 2.84 pulses per degree of rotation. Any thoughts from my fellow tinkerers? ;^)

Product SEN-10643 | about 11 months ago

UPDATE 8/2/2011: Be aware that this version (45A) can handle up to the 51.8v without smoking the sensor itself, the voltage divider circuit will easily exceed 5 volts if you attempt to sample the higher voltage since, unlike the current, it WILL NOT scale the voltage down to a 3.3v level. In short, if you need to sample voltage from anything higher than 13.8v then you may want the 90A or 180A version instead which will correctly scale the higher voltage (at a slight loss of resolution).
Arduino A/D inputs smoke quite nicely when you put high voltages into them 8/

If you are flying there yourself (as I would), the two closest General Aviation airports are:
KBDU: Boulder Municipal Airport, KLMO Vance Brand Airport and KEIK Erie Municipal Airport all of which are within 15 miles of SparkFun.
(be aware of high elevations, short landing strips and prairie dogs in the vicinity of runways though! I’m not sure about prairie dogs, but turtles crossing the runway on takeoff in Slidell, LA made strange popping noises and a rough ride!).
KDEN Denver International Airport is the closest major airport, roughly 28 miles from Sparkfun.
All of this from a boy in Houston, TX. And you thought all of us Texans rode cows! ;^)

When used with a regulated 12v power supply and a constant 1 amp draw it reads correctly, but when the power is bumped up to 30 volts at 1 amp, it goes off-scale high (1023). What gives? Is the product listing wrong here or is the datasheet? If I would have known only the 90 and 180amp versions could handle the higher voltage then I would have spent my $20 each on those x3

+1 on this as I managed to accidentally fry one of the A/D inputs on my UNO. Is this a drop-in, no-muss, no-fuss replacement?

Until they are made available here, the Deans Ultra Connectors can be found at www.towerhobbies.com
I went this route to avoid soldering wires directly to the board and enable this to be used in different projects.

Product WRL-10505 | about 11 months ago

Has anyone gotten one of these to work with an Arduino? If so, what is the minimum number of connections needed to get this fellow up and running?

Product WRL-09954 | about 11 months ago

I’m using this with a new Arduino UNO and can get into command mode with $$$ and enter commands and receive text back from the WiFly.
When I attempt to associate with my WPA-PSK protected NetGear WNDR3700v2 router I get AUTH-ERR even though every other device on my network can connect with the router just fine.
(and yes, I did set the SSID and PassPhrase)
It was mentioned elsewhere that the shield may need to be moved away from the Arduino because of a “bad ground on the Sparkfun Shields” before being able to connect. I’m not sure how much there is to that but can anyone else here offer up any suggestions on why I’m not able to connect?
Update 7/17/2011:
MY BAD! Turns out I had the wrong WLAN AUTH method set. Unit now connects extremely fast to the WNDR3700 (N600) router using AES encryption. Powered it up with a battery and walked two blocks down the street and still didn’t lose the connection. Awesome!

My hamster recently died. Will this work on him?
