It’s a microcontroller built into a breadboard. Actually, TWO microcontrollers. Both are Arduino-compatible. ATmega16U2 and ATmega328P. It comes in both black, white, and pink because style matters. P.S. The bottom side is filled with Lego connectors. We love Legos, but we bet we’ll never use that feature. Still, it can’t hurt.
In an earlier post, we discussed how surprisingly useful well designed voice control can be. There are open source software solutions for voice control, but they aren’t integrated with hardware, and there wasn’t really a kit to help one get started. Now there is. Here’s an open source kit for adding voice control to whatever
Tibbo makes modular microcontrollers, with plug-in modules for I/O ports (e.g. DB9), relays, sensors, digitizers, etc. They have different sizes, the largest of which is available as a Linux version.
Andrew Lim wrote in to discuss strategies on dealing with ripple noise in 2-photon imaging systems, particularly when using resonant scanners. He writes: This isn’t so much a tip as a problem with resonant two-photon scopes that several people have told me they also have but I haven’t seen a solution for (other people apparently
Sanworks has a whole series of devices for behavior experiments. Everything is open source and well documented. You can also pay them to assemble the devices if you choose. They have also created a pulse generator called the PulsePal, and Arduino Due-powered device offering 2 trigger channels and 4 output channels (minimum pulse width 100
“> Leonardo Lupori and Raffaele Mazziotti are two fellows in lab of the excellent Tommaso Pizzorusso. They have developed an intrinsic signal optical imaging rig and are sharing all of the materials. Here’s their web site with the resources and links. More on intrinsic imaging… Yet more again…
The Raspberry Pi 2 is here, and thus there are good deals on the Raspberry Pi B+. You’ll have to decide if any of these kits are a good deal for you. The Raspberry Pi 2 will be at the same price point ($35) as the prior generation. Anandtech has a nice rundown on this
It’s been promised for a while now, but someone has to do the hard work to make it happen. That inevitably involves some pretty pitiful looking stepping stones on the way to the promised land. So try to ignore the fact that this is among the worst looking 3D printed crap you’ve ever seen and
Austin Blanco has designed and built an open-source system for controlling complex imaging systems called TriggerScope. It’s highly customizable out of the box, and both the firmware and software are open.
Lytro is releasing a development kit for their light field camera. That’s nice, but it pretty expensive. And we’ve been able to buy light field cameras for technical uses for years. What’s special about Lytro is that they made a consumer camera. Labrigger bought one of the first ones when they came out. So one
One can use a Raspberry Pi as a highly customizable 20 MHz scope with this cute little BitScope Micro. (about 120 euros, from the OE store) They have their own software too. With probes attached:
MultiSIM BLUE is yet another free, SPICE-based electronics simulator– this one is linked into the MOUSER catalog, to streamline parts sourcing. Also includes PCB design tools.
ScanImage 5 supports resonant scanning with a wide range of hardware. So custom rigs can add resonant scanning pretty easily, while sticking with ScanImage for acquisition. It takes about $10,000 worth of electronics from National Instruments. In addition, you’ll need the resonant and galvo scanners themselves. From Cambridge, resonant scanners are under $2000, and conventional
Our friend Christian Wilms tipped us to Austin Blanco’s blog, which has some posts you all might be interested in: Characterizing unknown optical components A few notes on Arduinos, their timers, and using them with rotary optical encoders Long-term considerations when buying or building and imaging system Surprisingly clean +/- 5 volts from USB or
Raspberry Pi is the most popular mini computer right now, but there are other options. SolidRun sells two. The first is a sleek cube called the CuBox-i (pictured above). The second is a barebones board, the Hummingboard.
