[Damien] wanted to build a thermal camera. He was dismayed about how much a microbolometer costs so he salvaged one from a dead FLIR he picked up on eBay for 75 pounds. That’s about $100, and less than half what a new sensor costs. He selected one that didn’t turn on, which he hoped meant the Lepton 3 160×120 pixel microbolometer would not be the reason the camera failed.
Once it arrived, he pulled the pricey module, connected it to a breakout board and a Raspberry Pi. His gamble paid off; it worked fine. That wasn’t the end of the project, though. He went on to make a portable, self-contained camera with a rechargeable battery and an LCD screen.

Photonicinduction is back! The Brit famous for not setting his attic on fire has built a 20,000 Watt power supply. It connects directly to England’s national grid with huge connectors. Impeccable fabrication and triple servo controlled variacs, and apparently this will be used for making a lot of hydrogen and oxygen through electrolysis of water.
In case you missed it, there’s a group buy for Flir’s Lepton thermal imaging module. Here’s the breakout board.
Need to solder something away from an outlet, and all you have is a disposable lighter? There’s a fix for that.
A Raspberry Pi case designed to be compatible with Lego. Now we need a hat/shield for NXT connectors.
Need another channel in your RC remote? Here’s this. It uses the gyro gain channel on a receiver. If someone wants to figure out how this works, wee do have a rather cool project hosting site.

Here’s something impossibly cool: The Macintosh PowerBop. It’s a Powerbook 170 with the floppy drive replaced with the radio in a cordless phone. It was part of France’s BiBop network, and you could buy private base stations for use at home. It is technically possible to use the radio as a wireless link to a modem, but [Pierre] couldn’t get PPP or a sufficiently ancient browser working. Plus ten points for taking it to an Apple store, and another twenty for trying to connect to our retro edition.
Chicken Lips. [Fran] and our very own [Bil Herd] are hanging out a bunch and recalling [Bil]’s time at Commodore. For this little featurette, [Bil] brought out his very own Commodore LCD. There are three of those in the world. Also included: tales of vertical integration, flipping bits with photons, and 80s era ERC.
Thermal imaging cameras are all the rage now, and one of the best IR cameras out there is Flir’s Lepton module. It’s the sensor in the FLIR ONE, a thermal imaging camera add-on for an iPhone. Somewhat surprisingly, Flir is allowing anyone to purchase this module, and that means a whole bunch of robotics and other various electronics projects. Here’s a breakout board for Flir’s Lepton.
Electron artisan [Mike] recently got his hands on a FLIR ONE, and doing what he does best, ripped the thing apart and built the world’s smallest thermal imaging camera. Compared to professional models, the resolution isn’t that great, but this module only costs about $250. Just try to find a higher resolution thermal imager that’s cheaper.
With this breakout board, you’ll obviously need a Lepton module. There’s a group buy going on right now, with each module costing just under $260.
The Lepton module is controlled over I2C, but the process of actually grabbing images happens over SPI. The images are a bit too large to be processed with all but the beefiest Arduinos, but if you’re thinking of making Predator vision with a Raspi, BeagleBone, or a larger ARM board, this is just the ticket.
You can check out some video made with the Lepton module below.
This is also project number 3000 on hackaday.io. That’s pretty cool and worthy of mention.

[Mike Harrison], the mastermind behind electricstuff.co.uk has just finished reverse engineering the Lepton module found in thermal imaging cameras — he then created his own, and perhaps the world’s smallest thermal camera.
He took apart the Flir One iPhone thermal imaging unit and pulled out the magical part that makes it all possible — the Lepton module. It only has a resolution of 80×60 pixels, but in the world of thermal imaging, it’s pretty decent. You can buy it for $250 (for the module) in order quantities of 1000 straight from Flir.
His blog has all the details about figuring out how to interface with the module, and it is really quite impressive. Once he had it all understood he set out to build it into a small thermal camera. The case is machined out of black acrylic, and an iPod nano screen is used as the display, as 80×60 scales up nicely to the 320×240 resolution of the iPod. A home-brew PCB connects to the module, has a voltage regulator and charging circuit for the lithium ion battery — which is then connected to a prototype iPod nano PCB with some of the features removed — he says it was a nightmare connecting it all, and we don’t blame him, that’s some serious hacking skill!
