  • Product BOB-11611 | about 8 months ago

    Mine just arrived today. Nice job with the dedicated tutorial page! It might be cool to screen the text in just one direction.

  • Product CEL-10138 | about 8 months ago

    (Probably) Final Update: CanaKit’s stock estimates were based on what they thought they could source from SFE.

    • There are no connectors for this module.
    • There is no breakout board for this module.
    • There is no devboard for this module.
    • It’s too bumpy, small and expensive to use as a drink coaster
  • Product DEV-11780 | about 8 months ago

    If you’re debating whether or not to branch out from Arduino into a different board, you owe it to yourself to give Teensy a try. It’s an easy transition with a lot of programming space, speed, and inputs/outputs in a, well, teensy package. I’ve had to make nearly no changes to existing Arduino libraries to make this work with my existing code.

  • Product CEL-10138 | about 8 months ago

    Update: Tech Support (thanks Michelle) pointed me to Canakit, which has a finite number of both the breakout and dev boards in stock. Get ‘em while you can.

  • Product CEL-10138 | about 8 months ago

    BEFORE YOU BUY Contrary to the description, SFE carries neither the mating connector nor the eval board. They’ve retired the dev board, the breakout board, and don’t carry the connector.

    I’m at my wit’s end with this.

  • Product WRL-11777 | about 8 months ago

    Agreed, Doc! These comments bury good information one needs to use/hack the product. I’m all for freedom of speech but whining about the cost so much is a lot like filibustering. If you can make one better… fine, do so, maybe I’ll buy from “you” but I’m really tired of the Price Police.

  • Product SEN-11418 | about 8 months ago

    Images are JPEG. There is no (documented) external access to the SD card. In fact, the only digital communication at all with the camera is via PIN3, which is simply the power/shutter button. You may be able to hack the board to access the card directly, but that would entail a lot of tracing and trial and error since the schematic is not available – this is not an OSHW device. (I wish it was, it might get more community support.) However, I found them very responsive to questions.

  • Product SEN-11418 | about 8 months ago

    Sure. You edit the configuration file on the SD card to set how you want to control the camera. You have two shooting options. 1) trigger the camera to take a photo every n seconds via the PHOTO_INTERVAL parameter in the config file, or 2) set that param to 0 and use the microcontroller to trigger the button. Using the latter technique, you need to put the camera into standby mode while you power it up, which can also be done by the controller. In both modes, the images are stored directly onto the SD card. No streaming is involved. I’m currently using a HackHD, GPS module, and Arduino Uno to map bike trails. Works great as a poor man’s google streets. Details of the config are here: http://www.hackhd.com/downloads/hackhd-v115-instructions.pdf and they also have some videos showing the timing necessary to put the camera into different modes.

    Before you RTFM, visit the site and download the latest PDF. The link above is out of date (2011) and there have been changes.

    Also, I can confirm that the current releases of the XBee Explorer Regulated work well with this module.

  • Product PRT-11231 | about 11 months ago

    I thought I might be able to power an Arduino Due with this, but am skeptical after giving it a try.

    I loaded the “fade” sketch and had an 10mm LED and 220kΩ resister on pin 9, soldered the 3.3V jumper on the PowerCell, hooked up SFE’s 6Ah battery, and connected the grounds. The VCC went to the Due’s 3.3V pin.

    The results weren’t good. First, the Due’s “L” LED (associated with digital pin 13) was only sort of half-bright, when normally it is full bright with other power sources. Also, the sketch wasn’t running. The LED on pin 9 was at full bright. So I pressed the reset button and then LED on pin 9 burned out.

    Due’s regulator was bypassed using the 3.3V pin, but the PowerCell’s regulator should have taken its place. Maybe someone can explain why not. I don’t think I can use this to make a LiPo-powered Arduino – it was kind of an expensive lesson.

No public wish lists :(
