The ESP32 is looking like an amazing chip, not the least for its price point. It combines WiFi and Bluetooth wireless capabilities with two CPU cores and a decent hardware peripheral set. There were modules in the wild for just under seven US dollars before they sold out, and they’re not going to get more expensive over time. Given the crazy success that Espressif had with the ESP8266, expectations are high.
And although they were just formally released ten days ago, we’ve had a couple in our hands for just about that long. It’s good to know hackers in high places — Hackaday Superfriend [Sprite_tm] works at Espressif and managed to get us a few modules, and has been great about answering our questions.
We’ve read all of the public documentation that’s out there, and spent a week writing our own “hello world” examples to confirm that things are working as they should, and root out the bugs wherever things aren’t. There’s a lot to love about these chips, but there are also many unknowns on the firmware front which is changing day-to-day. Read on for the full review.

The Bay Area Maker Faire starts today, but the Hackaday crew rolled in early for something new this year. Friday has traditionally been just for exhibitor setup but this year a few extra groups were on site to see everything come together. Most notably, school field trips. How awesome is it to skip the normal class schedule and hang out at the fair? Also able to get in are media and industry.
I had a great time. Watching everything get setup is often more interesting that seeing the finished display. It’s also much quieter, many fewer bodies (Saturday afternoon is usually a mad press of people) and people haven’t yet lost their voices or the fallen into the monotony of voicing the same explanation over and over again.
Above you can see a few of the friends I ran into. [Windell Oskay] is one of the 2015 Hackaday Prize Judges. He had a freshly minted copy of his new book which I first heard about when visiting Evil Mad Scientist Labs last fall. I also ran into [Kevin] who is the creator of the Arduboy. I first met him at BAMF last year and this year he makes a triumphant return with the new version of Arduboy which overshot it’s Kickstarter by an order of magnitude in just a few days. And who else should I bump into but [Brian Benchoff]. He lives in Pennsylvania and I in Wisconsin so we look forward to hanging out when Hackaday hits the road. I also said a quick hello to [Caleb Kraft] who was slinging veggie paella all evening.
[Brian], [Sophi], [Matt], [Jasmine], [Rich], and I will all be at tonight’s Hackaday Meetup. Anyone in the area won’t want to miss this one. There are a ton of awesome hackers already planning to clink glasses starting at 7pm. All you need to do to join in is RSVP.

Back to the action; I made a quick Friday first pass which still took about three hours. The setup changes just a bit each year… generally things are in the same places but of course returning exhibitors have made a year of upgrades and there’s always a lot of fresh and new on hand. I don’t remember seeing the probability machine last year. It has reservoir of marbles at the top which are being steadily dropped into the “Plinko” style peg-board showing a distribution which has a higher probability toward the center.

Here are just a few more favorites. The Kijani Grows booth has a couple of full aquaponics setups that are worth checking out. I spent some time with the Firepick Delta guys. Sand plotters are always fun and there’s a giant one in one of the booths. I may try my hand at lock picking in The OPen Organization of Lockpickers tent today. And [Louis] of SmartMatrix is launching his Kickstarter to bring fully-assembled versions to people who don’t want to solder the one available in our store.
That’s all for now, I’m off to see as much as is humanly possible. If you’re at the Faire today or tomorrow track us down for some stickers and other swag, and don’t forget tonight’s meetup that I mentioned above!
By now you’ve probably heard something about Google Wave which saw a private preview release last week. The video above is an eight minute overview of the core functionality that the Wave offers. Wave development was based on the premise that email, invented 40 years ago, has not kept pace with our working needs as a technological society. Wave looks to improve on the email model by combining real time chat features, in line conversations, and web tools like document sharing and real-time translation.
The team here at Hack a Day uses a collaborative effort to bring you the best hacks we can find. To do so, we use a combination of email, instant messaging, document sharing, IRC, and old-fashioned conference calling. We’re waiting patiently for our invitation and although we’ve been skeptical of some past Google offerings, we hope the advertised features of Google Wave will allow us to improve our team coverage for the benefit of our readers.
Are you already using Google Wave? Please share your experiences with us in the comments.
