Friday Product Post: Level Up and Get Beefy!

We are putting all of our points into STR today!

Favorited Favorite 0

Hello, everyone! Welcome to another Friday Product Post. It's been a busy week for all of us trying to catch up from Memorial Day. That said, we were still able to bring you plenty of new products, as well as launch one of our semi-annual Clearance Sales! You can find the sale page here, or in the supercategories at the top left of the page. There are some very popular items up for grabs so don't miss your chance – the sale ends at midnight MDT on 6/10/2016. Today we have a new sensor, control relay, and batteries on deck. We hope you are ready to check them out, because here we go!

SparkFun Beefcake Relay Control Kit (Ver. 2.0)

Your 5V system can wield great power with this big, beefy relay board. How does 10A on the NC contacts and 20A on the NO contacts at 220VAC sound? The SparkFun Beefcake Relay Control Kit contains all the parts you need to get your high-power load under control. Only minimal assembly is required!

The heart of the board is a sealed, SPDT 20A/10A Relay. The relay is controlled by 5V logic through a transistor, and an LED tells you when the relay is closed. This is a kit, so it comes as through-hole parts with assembly required, which makes for some nice soldering practice. Screw terminal connectors on either side of the board make it easy to incorporate into your project.

SST Liquid Level Sensor

The SST Liquid Level Sensor provides single point liquid detection via a TTL compatible push/pull output. This optical liquid level sensor features a miniature design that allows for installation in areas where space is limited. Thanks to its minimal solid state design, this sensor has been built without moving or mechanical parts that can be jammed and stop working.

Lithium Ion Battery - 6Ah

Earlier this week we released our new iteration of the 6Ah LiPo Battery. This tank of a battery is nearly identical in function to its previous version. Now it is blue and features better documentation!

Polymer Lithium Ion Battery - 40mAh

In addition to the 6Ah Lipo, we also released our new 40mAh version. Unfortunately this little guy isn't blue like its big brother, though it still has better documentation.

Alright, folks, that's it for this week. Be sure to check back with us next Friday so we may help brighten your day. Until then, happy hacking!

  • Why not just use an SSR instead of a relay? SSRs are really cheap anymore.

  • Well, fortunately, the data sheets for the new batteries do have mention of "weight" -- "<150g" for the 6Ah, and "<5g" for the 40mAh one. (My "Flashy Santa Hat" had a problem last year with the weight of the three AAA cells -- I'll need to dig out my notes, or maybe just measure the current again, and see if I can use the 40mAh battery -- but, there are "only" 204 shopping days 'till Christmas, so I should have time!)

    BTW, I put "weight" in quotes above in acknowledgement that grams are a measure of mass, not weight (which is gravity's effect om mass).

    • Just looked it up -- the average battery current (according to my Fluke DVM) is 4mA, so the 40mAh battery should have no problem running for 5 or 6 hours. (It pays to keep a "log book" with such notes!)
