LED Kitchen Timer

Dave wrote in to tell us about the kitchen timer he made:

I just wanted to say thank you for putting together such a great site and set of products. I’m a newbie and after about 4 months o studying your articles and using the Diavolino as my development board, was able to make a cool little kitchen timer for my parents this Christmas. I definitely could not have done it without your articles and products.

He documented the project with a series of videos (youtube playlist) showing his progression through building it. Shown above is the breadboarded prototype next to the finished timer.

Thanks for sharing your project photos and videos, Dave!

LED Pez Menorah 2013

Joyce sent us this picture of her 2013 Lord of the Rings Pez dispenser LED menorah.

I thought I’d share my new menorah hack with you all. Friends even started asking about “this year’s theme” so I guess it’s now an official tradition.

She incorporated our new multi-colored LED Menorah kit into this one. You can find our previous LED Pez dispenser menorah posts here and here.

LED Vertical Blinds

dinofizz posted in the forums about the LED display based on the Peggy 2 he installed on his vertical blinds:

I had custom PCBs made to help daisy chain the vertical blinds (they’re sitting on top of the horizontal beam from which the blinds hang). 300 ft spool of 16-way ribbon cable completely used up. Around ~4000 individual solder joints, and I’m still using breadboard to hold things together at the moment! Took me forever.

He linked to a few more build photos over in the forum post, and he even posted some video of it in action:

Surface Mount LEDs on a Through-hole PCB

Peggy 2le Surface Mount

Peter T. recently stopped by our shop with his Peggy 2LE and showed us his incredibly cool hack. He had noticed that the 0.1″ pin spacing for a standard through-hole LED is just about perfect to accommodate LEDs in a 1206 surface mount package.

Once he had finished populating all the LED locations, he brought it by again. He used an alignment jig he had made to keep everything in straight rows while soldering.

The surface mount LEDs look great on the grid designed for T-1 3/4!

We plugged it in so we could see his pretty orange LEDs in action. Thanks to Peter for bringing it by and letting us take pictures!

From the Mailbag: Meggy Jr RGB

Ted from Boston wrote in with nice things to say about our Meggy Jr RGB handheld LED matrix game kit:

My experience with your company in my recent purchase of a Meggy Jr. Kit was nothing but outstanding.  It was a joy from the ordering process, delivery to the product and documentation!  Looking forward to doing business with you again.

Thanks, Ted!

DIY Deck Ambiance with Flickering LEDs

Jack Olsen (of the awesome 12-Gauge Garage) wrote in about using our flickering LEDs to line the deck and pergola he had just built.

He says, “The LED candle effect is great, and really gives the place a relaxed feel at night.” You can read more about the deck project over at the Garage Journal forums, where he describes the build in more detail:

It has 28 real candles on it that I’ve hollowed out to accommodate flickering LED lights. It’s pretty convincing.

I have a pair of 3 v power supplies — each feeds half the light set. They’re plugged into a switched outlet with wire running down along the edge/underside of the deck and up through one of the pillars, then sneaking around the back of the wooden frieze thing and into holes drilled in the backside of the frame.

He even sent us a before shot, so you can see just how from-the-ground-up building the deck was. Thanks for sharing your project with us!

Senko [Flash]

Tatsu Iida, a member of oxoxo [zero by zero] wrote in to tell us about the interactive LED installation entitled Senko [Flash] which they showed at the Tokushima LED Art Festival in April.


They used a Peggy 2 to drive a field full of LED illuminated spheres, along with IR sensors to detect visitors entering the array. Each new person would trigger a new sphere to light up and move through the field.

This is the largest installation we’ve ever seen based on the Peggy 2.
