Today, we have passed a major milestone: nScope is in stock at Amazon. We (Nick and David) have learned so much in this process, and we’re super excited that we can finally get nScope to those who missed our Kickstarter campaign. But this is just another step forward in the road ahead of us.
Verify Ohm’s Law and resistor power ratings. Build a voltage divider circuit block. How to use a multimeter. Ohm’s Law: : the voltage across a resistor is the current through it multiplied by its resistance (V = IR). Note the language used – voltage across and current through (never never never refer to the voltage[…]
Get familiar with the tools in your nScope kit. Breadboarding, using a multimeter, and using the nScope. A multimeter is a tool for measuring a variety of electrical properties. Plug the black probe into the COM pin, and the red probe into the VRM… pin. To measure the voltage across a component, set the dial[…]
Get your lab kit and make sure everything works. How to use a breadboard, wire strippers, and the nScope’s power supply and software. Open up your lab kit and make sure you have the following components : Download and install the nScope application from Strip a wire: Use the appropriate hole in the wire strippers[…]
nScope 0.7 is now available for download, and with every new version of nScope software, there is new firmware that needs to be loaded too. Here’s a breakdown of what happens during this process. First, nScope software is updated. Once the new version is loaded, it connects to the nScope and should see that the[…]
nScope has always been intended for low-cost educational purposes, and the Raspberry Pi single board computer is the perfect companion for nScope. And now, with the latest version of Raspian, the Raspberry Pi operating system, experimental openGL drivers are available! Since nScope draws the oscilloscope graph with openGL, this means nScope now runs really smoothly on Raspberry Pi.
Today we received our first nScopes from our manufacturer. They are pre-programmed, hardware/firmware tested, and ready to ship.
The past month has been an absolute sprint for us. The fall academic quarter has begun at Northwestern University, and we were pulling late nights getting ready. But we’ve made a ton of progress, click the link to check it out!
We got a shipment in last week. After a few design iterations, we finally settled on a design for our PCB ruler, nScale. We now have enough nScales in house to ship to our $5 backers, and include with each and every nScope shipment. We’ll be packing these up and sending them out to 95 backers who backed us at the $5 level within the next week. The rest of our backers will be receiving them with their nScope package.
What a month it has been. We just concluded our month of crowdfunding on Kickstarter, and we raised over $187,000 from over 1700 backers. This is a success we could never have imagined. As well look ahead, we plan to finish prototyping and deliver the most recent generation of nScope by September 2015.
