USB Armory: Open Source USB Stick Computer

If you need a bare-bones, security-focused, micro computer, the USB Armory may be what you're looking for. The differentiating feature is ARM’s TrustZone trusted execution environment on this USB stick computer i.MX53 processor. The USB Armory is full-blown computer (800MHz ARM® processor, 512MB RAM) in a tiny form factor (65mm x 19mm x 6mm USB [...]

How to Crowdfund Your Hardware Start-up

I spoke with Daniel Dern over at IEEE Spectrum about why we decided to crowdfund the T400 temperature datalogger. Daniel's article is spot on with the most important reasons a hardware project should use crowdfunding: you know if people want it, you know how many to make, and you have the money to do it. Crowdfunding—collecting money from a [...]

USB telescope controller

Kevin made a kill telescope controller. It is a simple Arduino-based device for interfacing with a motorized telescope mount. This would be a fairly simple device to make. How big is the interest in something like this? Maybe Pax Instruments should manufacture one. There’s many complex systems for automatically pointing a telescope at an object [...]

Should You Care About Software Defined Radio?

In addition to cost and flexibility, Hackaday's article explains why software defined radio is awesome and why now is a great time to get started. First off let’s reconcile what is meant by “radio”. If it sends or receives via radio frequency it has a radio in it. This means your WiFi router, your cellphone, your [...]

BeagleLogic Logic Analyzer

With the BeagleLogic, Kumar Abhishek's seeks to turn you Beagle Bone Black into a 14-channel, 100Msps Logic Analyzer. The project helps create bindings of the PRU with sigrok, and also provides a web-based front-end so that the logic analyzer can be accessed in much the same way as one would use the Cloud9 IDE on the BeagleBone/BeagleBone [...]

Injecting SD Card Bootloaders

Wow, Frank's technique for changing his bootloader would make Rube Goldberg proud. [Frank] has a Ultimaker2 and wanted to install a new bootloader for the microcontroller without having physical access to the circuitry. That means installing a new bootloader for the ATMega2560 without an In System Programmer, and as is usual on AVRs, the bootloader can only [...]

TSL2584TSV Ambient Light Sensor

Here's a light sensor we're thinking about using for a future project. It's not lab instruments quality, but there a few fun projects we have lined up. The TSL2584TSV is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal output with a fast-mode I²C interface. The device combines one broadband photodiode (visible [...]

Pax Instruments launches new products

If you keep track of the store you already know we recently launched a few new products. We are putting the finishing touches on the T400 and some of our components have been rolling in. We have purchased extra of everything, so we can make these wonderful parts available to you for your projects. The [...]

Raspberry Pi Solar Weather Station

PiJuice made a solar powered weather station. The key component  is their self-deisgned PiJuice solar module with integrated battery specially designed for use with a six volt solar panel. A full linux machine like the Raspberry Pi is probably overkill for a weather station. The power requirements can be reduced by using a lower power ARM [...]

Haber Process via Ultrasonic Cavitation

Peter Walsch aims to apply ultrasonic cavitation technology to the nitrogen ammonia manufacturing process. His proposed method is not necessarily more energy efficient, but it means you may be able to generate ammonia from nitrogen and hydrogen on a laboratory scale. More importantly, however, is how this method might be applied to generating other chemicals. [Peter]’s idea is [...]
