  • Product TOL-10214 | about 2 years ago

    Mine did not come with a quarter on it, but more concerning is that the unit is marked “5.5V 500mA +/- 50mA."
    It appears to be a different model number and will not charge either a Blackberry or Samsung phone.
    Why would anything with a USB socket carry 5.5VDC? Odd.

  • Product WRL-10938 | about 2 years ago

    1. I wired CTS-I to RTS-O because I wasn’t going to use any flow control. Then I gave the board 5V. Found the device with the Windows XP Bluetooth utility in control panel just to see if it was alive. “1234” is the passkey. Cool. Disconnected it.
    2. Using a SparkFun FTDI Basic Breakout, I wired the connections for ground, TX and RX. Opened Hyperterminal. Connected to it at the default 115200. Typed $$$ and CMD appeared, red light flashed fast instead of slowly. Typed “SU,96” to change the baud rate to something my PIC could communicate at. AOK was response.
    3. Wired up a PIC and programmed it to pause 5 seconds, then serially output “Hello World” followed by a return and line feed. Goto start of program.
    4. Restarted, paired, opened Notepad. Pause. “Hello World” CR “Hello World” CR “Hello World.” Success.
      This device will become the transmitter of a transport for a digital audio workstation. Record, undo, play, return-to-zero. Transmit all keyboard shortcuts and macros with hardware buttons. Record guitar and vocals in acoustically good rooms of the house, away from computer noise. Longer range than a wireless keyboard. This is a good product, just read all the stuff. I hope this conceptual framework gives somebody a start.
  • News - SparkFun in MicroCenter | about 3 years ago

    Yup. Checked out Micro Center in Mayfield Heights and spent more than I wanted to just because I was shopping at SparkFun.

  • Product WRL-00582 | about 3 years ago

    When the unit is in Auto mode, you can access Command mode using a serial port connection. Don’t try to connect to it over Bluetooth from a computer; in Auto mode, the device is a master and won’t respond.
    Having them hook up automatically is not difficult. Set one to Auto mode and store the address of the second unit using the menu. This makes for a solid data pipeline between the two.

    Terrific product. For my PIC projects, it’s like having an 8-channel logic level oscilloscope. My only gripe is that it doesn’t have a 10" display and carrying handle.
    Seriously, I solved two vexing problems right out of the box. The first was a power supply issue. In my haste to wire up a project, I had forgotten an important decoupling cap. With so many probes available, I stuck one on the power line and saw tons of dropout. Stuck a cap in place and the problem was solved.
    The second involved an input pin multiplexed with MCLR (reset) on a PIC. Logic revealed that I needed to remember to turn the MCLR function off, since I didn’t need it anyway. When power was applied, incoming data to the pin was resetting the thing and never getting into the code.
    I thought a scope was useful. Now I can put probes all over the circuit: rails, inputs, outputs, and before and after transistors. Seeing the whole circuit operation makes me really productive.
    Yes, this is my first logic analyzer, but I’m completely happy with it.

  • Product TOL-10244 | about 3 years ago

    Pretty responsive little scope, perfect for a lot of basic stuff. The BenF firmware is a must; the end result is a pocket-sized product that acts like an expensive bench scope. Measurements in the new firmware appear in a list, just like my HP. It’s easy to take this anywhere and have answers fast.

  • Product TOL-09544 | about 3 years ago

    This is a terrific tool that saves a lot of time. Rather than changing code in a PIC I can hack away at a part while reading the datasheet. The interaction with a chip is immediate, and really satisfying when what I’ve sent it yields results. I had breakthroughs in an afternoon with the MCP4725 DAC and a 24LC16 EEPROM, and now I’m confident enough to send code to them through software.
    The only oddity I’ve noticed is that the pullup resistors will drop out at odd times, even when I’ve enabled them and given the blue wire a direct connection to Vdd. But I’m happily working through all the parts in my collection, and the working method with this board is like having a dialog with the electronics.

No public wish lists :(
