A Round of New Products for Friday

We have a round of bright new products for you to take for a spin!

We've got some new stuff this week.  I say that a lot, but we have a lot of neat stuff! We really do have a good selection for everyone, so let's see my top picks for this week.

Unfortunately I did make a few mistakes in the video and I hate it when that happens! The bussed resistors contain 5 resistors, not 6. They have 6 pins, one of which is a common pin, and the others are for the resistors. Silly me. Also, the LilyPad LEDs are called Micros, not Sequins. We had a last minute name change and we had already shot the video. Other than that, I think the video is solid. Let's look at the products for this week.

I really like using rotary encoders. They can be extremely useful since they can control a wide range of things. This rotary encoder is special because not only does it have a push-button, but its shaft contains red and green LEDs. You can use those to indicate multiple states for the encoder.

You'd hate to use a rotary encoder with an illuminated shaft only to cover it up with a black plastic knob, right? Well, thankfully we have these clear plastic knobs that fit perfectly with the rotary encoder above. They simply press-fit to the shaft and will let the LEDs shine through.

And to complete the entire ensemble, maybe you want to add this spiffy circular bargraph LED? It's a ring of 16 red LEDs that can be used to indicate the current position of a rotary encoder, volume levels, or anything else you can come up with. We are working on a breakout board that will hopefully be coming soon, but it's not too hard to use without one. The LEDs are just connected in 4 sections, each with a common ground. Check out the demo in the video for the whole setup!

If you use a lot of LEDs in your projects, you probably realize that hooking up a bunch of current limiting resistors into a breadboard can be a bit of a pain. Or let's say you are using several buttons or switches and have numerous 10k pull-up resistors. Thankfully, these bussed resistors make life a bit easier. They come in a 0.1"-spaced package and contain 5 individual resistors. We have them in values of 330 ohm and 10k ohm.

Moving right along! It seems like almost every week we have a new LilyPad or e-textile product. This week we have some new LilyPad LEDs for you to light up. The LilyPad LED Micros are similar to our other LilyPad LEDs but they don't have a current limiting resistor, so they're a bit more svelte. If you're using these with a microcontroller, chances are you won't need the current limiting resistor anyways. We currently have them in four colors, yellow, green, blue, and red. They come in rows of 5 that you snap apart (or not, we aren't going to tell you what to do).

So, you want to switch high-current loads but you don't want to use a lot of current to do it and you don't want to rely on a mechanical relay. Well, the easiest way to accomplish this would be to check out our new Solid State Relay Kit. It uses an 8A solid state relay and can easily hook up to a microcontroller with screw terminals.

Here is a good and trusty rocker switch. If you're looking for a no-frills way to turn something on and off, you can't go wrong with a rocker switch. This one's a bit smaller than our other one but can still handle a reasonable amount of current.

Everyone makes mistakes and we are certainly not immune from them. We made a mistake with our last build of these LilyPad Coin Cell Battery Holders. As it turns out, the silk for the battery holder was backwards making it relatively difficult to take the battery out. See that convenient cutout which would make it easy to take out the battery? Well, the battery slides in from the wrong side. Sigh. They still work just fine, it's just a bit of a pain to get the battery in and out. Get them cheap while they last.

We have a new revision of the Serial Accelerometer Dongle. We've changed the PIC out for an ATMega and also swapped out the accelerometer. The range is less than that of the old version, but it's cheaper this time. If you're looking for an accelerometer that talks over serial, check out the new revision.

And lastly we have a new revision of the Power Driver Shield Kit. We've added a protection diode to the power input on this version. Other than that, it remains the same.

Well, that's all we have for this week. Thanks for reading and slide on back next week for some more new products!

    I assume those among us not afraid of soldering, could reverse the LillyPad battery holder to make battery removal easy once again, no?

    Could anyone give me some idea of how much force is required to flex the sensor.

    For the Videographer/Producer:
    You’re shooting Rob wide-angle as he is seated at presumably square/rectangular table.
    But visually, the table’s sides widen noticeably as their planes fly behind the cam’s POV.
    And the back wall boxes.
    They are small in the middle.
    The first/second and last/next to last columns are wider.
    The boxes on each side wall are noticeably wider and seem to be jumping into “Hyperspace” as they exit the frame.
    With all that, the corners in the shot are almost vertical.
    Something you would never see in a camera’s viewfinder (still / video) without a tilt/shift lens.
    Or going to Photoshop / Avid afterwards.
    So the question is:
    Are you shooting forced-perspective?
    Twenty seconds into the 06-24-11, Rob’s movement does not tip your hat.
    Has anyone else noticed the elusive art of cuts-only?
    All the best……

    Carrying the 11-pin 10-resistor version of these resistors to go with the 10-segment LED Bar Graph you carry would add to its awesomeness.

    • If you can find them, we'll carry them. We couldn't find a good source! They come in 9-packs, which are 10-pin, but not 10-packs.

      • CF / about 11 years ago / 1

        If I find any, I'll let you know. The five packs can be doubled to make a 10 pack so that works for me.

    why only 480P ?

    • Sleepwalker3 / about 11 years ago / 1

      Yeah, I was wondering the same thing. Maybe they were just having an off day (thinking about the weekend and beer more likely) and forgot to shoot it in hi-res?

    3:19 was filmed in a jumbo jet.

    Wow - years ago, I begged Nathan to find a source for the ultra-cool control knobs on the Avid System 5 Audio Console.
    He finally came through! I wish they'd been available for my last knob-based project - I may have to re-do it just to take advantage of the the new knobs.

  • SomeGuy123 / about 11 years ago / 1

    In the video, you said the rotary encoder has an RGB led inside. It only has Red and Green.

  • Conrthomas / about 11 years ago / 1

    I love how Sparkfun will post a product, then also say "BTW here are like 3 different AWESOME accessories for it." eliminates multiple orders from multiple dealers, and ensure compatibility.

  • MarcMTL / about 11 years ago / 1

    If by 5 pins for the SIL resistor you meant to say 6 pins, then you'd be correct. Double rage face

  • Rob, on a separate note: Is there some way you could share pictures or list some of the stuff you have added to your
    Rover 5. I am about to purchase one and would to see how to modify the Rover (Preferably RC controls).

  • TeslaFan / about 11 years ago / 1

    Does the rotary encoder have the detente feature? I ask because it won't be as compatible with the LED ring if it does.
    It should be possible to get 16 pulses per revolution off the outputs if you read them right. But if it's detenting at 24, that would mess up the effect.
    I don't know what to use them for yet, but they're wacky cool!

  • aruisdante / about 11 years ago / 1

    Unless it was humor, your correction to the video needs correction... it's 6 pins, 1 common, 5 resistors :p

  • Isn't there a resistance of conductive thread, if I used a good length with those LED's?

    • Indeed there is! Dia will undoubtedly come along to correct me but there is something like 80ohms for foot on some of our thread. I believe we have a tutorial in the pipeline that will discuss this.

      • JordanDee / about 11 years ago / 1

        The resistance of our thread definitely varies quite a bit, however we do have thread with much lower resistance than that. Our product DEV-10119 is only 1.4 Ohms per foot.
