![]() You may have noticed that my audio sounds a bit better – that’s because Steve got me the Heil PR-40 microphone. It’s not like I was suffering, he got me the PR-20 a few years ago and I’ve been really happy with it. I wish I knew more about microphones, like what the frequency response curves mean ( PR-40 vs. PR-20) so I could explain to you why the PR-40 is so much cooler, but I’m too lazy to actually spend any time reading and learning. I did read about the two mics in comparison and the PR-40 has a couple of interesting features – the diaphragm of the mic is vibration isolated from the body of the mic, so I’m working without one of those spring thingys I had on the PR-20. I did a test to see if you could hear me typing while I was recording and it appears to be isolated really well. The PR-40 also has two screens between the front and the diaphragm acting as pop filters built in – but Steve got me the pop filter to go with the PR-40 so it’s hard to tell if I needed it or not. It’s way cool looking so it’s worth it either way! I love how compact it is not vs. #Icircuit windows plusMy PR-20 Plus the GIANT pop filter I had and the springy thingy (vibration isolator) – now it’s all sleek and cool looking. Next up I’d like to play a recording from Doug Ingram, aka on Twitter and in the live chatroom. He sent this in for last week’s show and unfortunately I forgot to play it. It still works this week but my apologies to Doug for not playing it on time. Hi there Allison, Steve, all the Nosillacastaways and anyone else listening to, reading or otherwise consuming this podcast. #Icircuit windows macIt’s Doug Ingram here from Sydney, Australia, the land of December summers and the starting point for one very auspicious Mac Mania cruise this year. Well, in true Nosillacast fashion, I need to start my contribution by identifying the problem to be solved. My problem is that I’ve been trying to find the time to send in a submission to the Nosillacast all year. Actually, looking through my GarageBand files, I should say that I’ve been trying to find the time for four years! I can’t believe that it’s been four years since I last sent in an audio contribution to the Nosillacast. OK, so I don’t have a problem that’s impossible to solve. ICircuit is the easiest way to design and experiment with circuits.The solution is to make some time and do it, despite how strange my family think I am for sitting in my little home office and recording myself. Its advanced simulation engine can handle both analog and digital circuits, Arduino microcontrollers, and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers. You use it as you would any CAD program: you add elements, connect them together, and set their properties. But iCircuit is unlike other CAD programs because it is always simulating. It's just like working with the real circuit. Instead, you just play with the circuit as you normally would, with the power on! You do not stop to take a measurement or spend a lot of time configuring reports. There are over 30 elements you can use to build your circuits. The app has everything from simple resistors, to switches, to MOSFETS, to digital gates. The app features a multimeter that you use to probe around the circuit to instantly read voltages and currents. If you want to see how a value changes over time, then you can add values to the built-in oscilloscope. The scope can simultaneously track many signals over time and features a variety of automatic modes that make it easy for you to grasp the behavior of your circuit. You can even export your circuits and PNGs, PDFs, and SVG files so that they are easy to include in reports or web sites. #Icircuit windows codeICIRCUIT FREE WINDOWS 1 CODEĪrduino simulator!
