I'm the guy behind Brixo, the electric bricks on r/geek yesterday. AMA
A friend sent me a link to the reddit post of my Brixo bricks, which blew my mind. Seems like there were a lot of questions, so with the help of a friend (since I'm new to reddit) I thought I'd hang out here a bit and answer any questions you have and talk shop.
A few things: -Yes, it's real, and totally works. And yes, it's a wireless connection based on proximity and light sensors as well as now being BLE enabled to connect with smartphones.
-We're just some tinkerers, and without any investment. So we've decided to launch on Kickstarter to raise money to manufacture Brixo at the lowest possible price to make them available to as many people as possible (while also paying ourselves for our time of course).
-We'll be launching a campaign in about 3 weeks, so if you'd like to be notified, just sign up on our site
Who am I? My name's Boaz Almog and I love science. You may have seen my TED talk a few years ago about quantum levitation. Brixo has been my passion project for the past few years, along with a small team of amazing people. I'm here to answer any questions on Brixo, quantum levitation, favorite Star Wars, pretty much anything.

Edit: Sorry everybody, was pulled away for a bit, but I'm here now! Answering questions with some help.
Not sure how to verify, but just updated our social media with this: https://www.facebook.com/brixotoys/ https://twitter.com/brixotoys
Had to go... Thanks so much guys it was a lot of fun. If you have more questions email me at [email protected]

Those patents are expired. Manufacturing good lego parts is difficult.
aldesuda129 karma
Which is necessary since (a) every brick made must fit every other brick made and (b) you don't want a noticeable skew after you stack 30, 40 bricks on top of one another.
All_Tan_Everything171 karma
And the more amazing part is that every brick made today fits every brick made 30 years ago
feni4531 karma
Unlike sloppy megablocks builds that lets all kinds of defects through. That's why the price range is so vast.
BenFett4 karma
Megablocks quality has increased exponentially in the past few years. I'm actually seriously impressed by their new quality.
BrixoBoaz19 karma
My thought exactly, but.. still far away from Lego. Lego bricks always have the same feeling and same building experience (not too hard/weak). We will work hard to achieve similar experience. Lucky for us the chrome coating upgrades the way the bricks feel in your hands and the building is more smooth.
BrixoBoaz29 karma
You're right. Fortunately for us we not making strictly plastic bricks - the chrome coating makes a completely different building experience (I might add more forgiving in terms of plastic feel). In any case, we invest heavily on getting a perfect building experience (we know how Lego competitors usually fails and feel cheap).
BrixoBoaz113 karma
Lego design - yes for compatibility. Fortunately, their patent expired so not need for any licensing. We would love to combine forces with LEGO (of course).
BrixoBoaz22 karma
They are. Well not the designs (that's a different patent) but the system of building blocks with its unique characteristics.
The_karma_that_could186 karma
How high is the voltage, and would it shock you to put your fingers in between 2 connection blocks?
BrixoBoaz378 karma
9V, like a regular battery. And nope, completely harmless :) You can even lick it, if you're into that
skymallow125 karma
9V will sting a little if you lick across the terminals, as I've learned the hard way in Uni.
renosis2416 karma
Has education slipped this far? I was licking 9v batteries in daycare. It wasn't a very good daycare.
neregekaj15 karma
Just stick the whole battery in your mouth with the terminals on your cheeks. Fool proof.
madsci18 karma
Can you give us some more technical details? How is the current bridging the gaps between the pieces on the base plate? How does it avoid shorting out when you place those last pieces?
BrixoBoaz63 karma
Connector pieces have two elastic arms (chrome coated of course) on both long sides that protrude towards the next brick. When two bricks are placed together the spring arm are pressed and electric contact is made. At the same time, the bricks are narrower than regular lego bricks so there is no contact between nearby bricks (its actually narrower than needed to be clearly seen and understood by the user). In addition to all that we have short circuit protection embedded into the battery brick. It will constantly limit the current, beep if short circuit and eventually cut the power temporarily if needed. Because, whatever can go wrong (or done wrong) will go wrong. We don't trust the user to be cautious.
dslybrowse160 karma
How does it feel to have something you made get completely discredited as "fake" at first? :p That other thread was hilarious with everyone trying to play /r/iamverysmart detective.
Narissis67 karma
I know Lego stopped making chromed bricks because the thickness of the chrome coating necessitated a second set of slightly smaller moulds to maintain clutch power, and this combined with the cost of using a third-party chroming company made them very expensive.
How does the clutch power of Brixo compare to Lego, and how do you keep it consistent?
BrixoBoaz65 karma
As you rightfully stated we need smaller molds to compensate for the chrome coating. The clutch power can be adjusted and after many trials (and errors!) we found the perfect coating thickness that made it feel smooth and firm at the same time. Its much smoother than Lego but feels strong enough. Consistency is about controlling the thickness of coating. We use electroplating which is a well controlled and repeatable process.
Dakar-A19 karma
Follow up- might you consider making sets without the electronic brick for AFOLs who would want chromed bricks?
danw65051 karma
As a future teacher, these things are have insane potential in my mind.. not enough kids have any interest in science, but most kids I meet enjoy Legos, at least a little bit. Now, I don't remember much from middle school electricity class, but if we can use Legos to start introducing things like circuits and switches, that's something a child can pick up as early as age 4 and take with them throughout their school years and hopefully beyond. By the time I was introduced to electric circuits, I was like 15 and the whole concept seemed too technical for me. I'd have to go read through books, and buy all the tools, and learn everything from scratch. This was at a time when my priority was to get out of school and play World of Warcraft. I am super excited at the prospect of a child's toy that introduces electricity in a safe way.
Will these be affordable for parents and early childhood educators? Are they easily breakable, or will they hold up to a 3-4 year old? Are they dangerous if, say, placed in a mouth? Also, are they something that a person with no electricity knowledge can purchase and use effectively?
BrixoBoaz37 karma
Affordable - yes. Kickstarter prices starting at $15, though will be around $35 for the normal package. Around $50 later on in retail. Breakable - No. Like LEGO bricks with highly durable chrome coating (imaging your chrome coated kitchen tap for durability) 3-4 age - not sure. Because of the small pieces. More like 6+. Electricity is not an issue - like touching a regular 9V battery.
danw65013 karma
Awesome! Yea 3-4 isn't even recommended for regular Legos now that I think about it. These seem so awesome.. please send some back in time to me as a child, thanks.
JosephsMythTheProfit48 karma
That quantum levitation video is the coolest thing I've ever seen. How long do you think it will be until that technology is used for transportation?
migvazquez9 karma
Not OP, but I'm pretty sure his hand had a small amount of charge built up from handling the circuitry. LED lights will do this with a small static charge as well
BrixoBoaz81 karma
Nope. The LED did not light before I connected it to the circuit. Its just the actual LEDs you are seeing (two yellowish LEDs).
TryAnotherUsername1317 karma
What? No. Static charge can reach several kV and would probably destroy an unprotected LED. The ESD protection would quickly (somewhere in the μs range) drop the voltage and what’s left would never be enough to power even a weak LED for more than a ms.
BrixoBoaz29 karma
You're right. We have resistors inside the LED to protect against power surges.
Robot_Spider44 karma
You did a TED about quantum levitation, and develop Lego concept/prototype designs in your spare time? My question: Are you hiring? :D Very cool stuff. Really enjoyed your TED.
Gabyx7629 karma
What level of complexity do you think is possible with your bricks ? Is it comparable to Minecraft's redstone system ?
Btw that's a really cool project for kids who want to learn about science !
BrixoBoaz33 karma
Thanks, that was the initial motivation. Complexity is almost infinite and in several levels - Mechanically - you could build 3D structures having multiple circuit branches (parallel & in-series). Electronically - combine electric components like transistors, capacitors for teaching electronics.
BrixoBoaz49 karma
Starting at $15 on Kickstarter, though will be around $35 for the normal package. Around $50 later on in retail.
BrixoBoaz51 karma
The most complex was the crane - https://www.youtube.com/watch?v=o0F71Dpoj20 The most bizarre were the models we build for the KS campaign - Minecraft dog with rotating head and a rotating arrow head.
ActivatedBag4220 karma
How soon do you think you will be able to sell these on a large scale?
Do you think you'll ever make a deal with LEGO or something similar so that they can sell your bricks?
BrixoBoaz28 karma
Hopefully real soon! We're planning on launching a Kickstarter campaign in a few weeks so we can manufacture and sell them on a REALLY large scale. As for Lego, that could be cool but we don't really see it.
pmYourFears11 karma
We're planning on launching a Kickstarter campaign in a few weeks so we can manufacture and sell them on a REALLY large scale.
That's not really a plan though.
Pretending you had the money already, do you know that Brixo can be manufactured on a large scale and whether you can do so in a cost effective way that stays close enough to the same tolerances that Lego have?
BrixoBoaz42 karma
We definitely do. We already closed deals with manufacturers and had several prototypes to test tolerances and quality of coating.
ActivatedBag428 karma
Awesome man! This has sooo much potential in engineering and entertainment!
cartoon_gun17 karma
Can you explain how they work in layman's terms? Like how are the connections made or how is the circuit created without a short?
edit: what do you mean by proximity? is that a few cm or mm distance? does it need to have the silver "circuit" blocks or are those just for show?
BrixoBoaz28 karma
The regular (chrome) bricks (4x1) act as conductors only. They are "regular" plastic bricks coated completely with chrome. Each have two small elastic arms that stick from the sides and touch adjacent bricks. The bricks are also a bit thinner to avoid short circuiting between side by side bricks. We have several switch bricks that act as regular switches - open / close the circuit. Proximity is one of them. It closes the circuit when a magnet is nearby (few cm, depending on the magnet). We will supply a magnet brick together with the Proximity switch.
madsci6 karma
Forget layman's terms, we've got a couple of skeptical electrical engineers here who'd like to see some details. Are you suggesting that there's inductive coupling between all of the adjacent bricks? Wouldn't that be very lossy and limit the number of usable orientations?
BrixoBoaz25 karma
Nope. Definitely not inductive coupling. The reason people are coating with chrome is because it is a noble metal - no oxidation layer, which keeps the contact Ohmic and excellent.
BrixoBoaz45 karma
Sorry, had a family thing, didin't realize how quick you guys are, I'm here now!
newvictim16 karma
Reddit expects AMAs to have people man them like they are actually chatting to the person. Then the AMA OP leaves after an hour or more. INSTANT GRATIFICATION!
BrixoBoaz22 karma
Just figuring out how all this works with some help... with that said... INSTANT GRATIFICATION! WOOHOO!

NomNomMeatballBanned8 karma
What'll the price be like? I imagine if its cheap enough it can be used as a tool to get children into electronics if it's safe enough.
BrixoBoaz15 karma
We're going to launch a Kickstarter in a bit where it's going to start with very small packages at $15, normal packages at $35. Retail will be about $50
Adjwater7 karma
what was the hardest part of the process behind Brixo, from technology to legal issues?
BrixoBoaz19 karma
I believe the hardest part is still ahead - marketing and selling. But so far the most difficult challenge was the smart switches - Brixo includes light/sound/proximity bricks which are smart switches. They connect/disconnect the circuit they are connected to. The major challenge was finding a way to disconnect the switch without killing its power supply (other wise it will not wake up when needed). Problem was solved after much work and out of the box thinking :-)
BrixoBoaz6 karma
Hey everyone, I had a great time (my fingers are on fire 🔥 in spite of the slow start) and I gotta go soon. If you have more questions email me at [email protected]
HNIRobertPaulson6 karma
Lego is known for making high quality toys while the rest of the toy industry seems to be racing to the bottom. Will these Brixo blocks have the same kind of quality and durability? It seems like the connection "nubs" or whatever they are might wear out over time. Also, chrome can wear or flake off. What are you doing to address these issues and what kind of wear and tear have you tested for?
BrixoBoaz16 karma
You're right. We certainly look up to Lego and their product quality. The bricks are make of ABS plastic (like Lego) hard coated with chrome. The coating is highly durable (have you see any peeling in your shower head? or tap?). Initial testings showed that the coating holds for hundreds of times. We will continue to do extensive testing once we complete our basic manufacturing capabilities (after the KS campaign).
slashy423 karma
How will you be handling quality control? Many Lego like blocks suck. Will yours be better? I'm concerned electrical connections will be hard to maintain.
BrixoBoaz11 karma
Yes, we plan on being as good as Lego. The chrome coating differentiate our product and gives it a completely different feel and a very unique and satisfying one. Not so much. We do not need a very good electric contact (just good). Even the slightest touch between two adjacent bricks will give an ohmic contact (~1Ohm) which is enough to make Brixo work well. Most of the times the contact are perfect.
BrixoBoaz10 karma
Don't expect to. Lego's patents on the basic shape expired several years ago.
Count_Sack_McGee2 karma
Can't imagine a child or many adults for that matter that wouldn't find this extremely entertaining. Do you have plans to market and sell these? they are very similar to Lego's, is there any concerns about lawsuits?
BrixoBoaz9 karma
We do. have plans to sell these kits at every retail and toy store. I am hopeful that our legal people did their job well. Lego's basic patents expired several years ago. Hopefully, we will live alongside Lego to give a more complete experience and not fight them.
BrixoBoaz1 karma
You mean flat pieces? Not in the first generation. We still haven't been able to find a proper solution to electrically connect adjacent flat pieces. But we are working on that.
whiskyart1 karma
What are some practical applications of quantum levitation / locking besides the awe-inspiring demonstrations at science fairs?
BrixoBoaz1 karma
Sorted by seriousness: 1. Transportation (people, cargo) 2. Precise control & manipulation (satellites in space, tractor beam..) 3. Display show (culinary, advertising, etc..)

Reddit themed kit with enough blocks to make 1 horse sized robo duck, or 100 duck sized robo horses, please? I only mention robo so I can stick those cool LED blocks in for their eyes.
valourunbound1 karma
So you mention BLE. Will the chip (there's gotta be a chip somewhere) be housed with the battery? I assume that large black block (that probably houses a 9v) also holds any required chips.
Can the block be disassembled? How long does your power last? Does it need to be recharged or replaced?
BrixoBoaz2 karma
BLE chip will sit inside the battery brick (9V). The block cannot be disassembled (just opened for battery replacement). Power lasts according to usage. Regular usage will consume no more than 100mAmp and white regular Alkaline 9V battery (>500mAh) it will last about 5 hours.

What do other fellow startup people think of Brixo?
This is like something they should be playing with when they're tired of developing their own startups.

Besides investment, what do you need help with? Building a community of designs would be really cool.
How are you going to protect yourself from the Lego overlord?
Also, proof?
BrixoBoaz1 karma
I think the major thing we need is a large and responsive community. One of the great things about Lego is its worldwide fans (AFOL, etc.). We are already working on building a platform for designs and ideas that will use Brixo. That is also the reason we decided on going first to Kickstarter (and not seek investment and straight to retail). By having a dedicated fan base we can build strong and health brand & product.
Meltingteeth-1 karma
Do you have any fear that you're totally going to get sued by Lego? I mean, they're definitely on reddit. They bitch every time you say Legos. As far as I can tell they're just metal legos, which seems far less fun than just using a wire...
BrixoBoaz2 karma
Legos. Legos. Legos. Sorry, couldn't help it. You shouldn't say Brixos as well. Maybe less fun (arguable..) but much more educational and less intrusive to the building.

It looks like your block rely heavily on the Lego design and function.
How do you intend to work with Lego and the patents they hold regarding the design and function of Lego blocks? Are you looking into a partnership with the company or are you looking to pay them for a license?
