<\/a><\/p>\n <\/p>\n However before we dive into the meat of the article, I wanted to share a little about Crazyflie<\/a>, a palm sized helicopter which is the perfect toy for summer.Completely open-source and designed for development and hacking, the Crazyflie Nano Quadcopters are among the smallest in the world.\u00a0 They weigh only 19 grams and measure 9cm from end to end.\u00a0 See it in action in this YouTube video<\/a>.<\/p>\n There are two basic kits, and they include everything you need to build this amazing gadget.\u00a0 The Crazyflie Nano QuadcopterKit 6-DOF<\/a> version uses a 3-axis accelerometer and a 3-axis gyro which enables it to auto-level while the Crazyflie Nano QuadcopterKit 10-DOF<\/a> version integrates extra sensors for altitude and heading measurement.\u00a0\u00a0 They both include a 2.4 GHz radio chip from Nordic Semiconductors and along with the Crazyradio 2.4 GHz nRF24LU1+USB radio dongle and antenna<\/a>, the helicopters can receive commands from your computer and send data back to it.\u00a0 To make it easier we also sell the quadcopters together with the Crazyradios:\u00a0 the Crazyflie Nano QuadcopterKit 6-DOF with Crazyradio<\/a> and the Crazyflie Nano Quadcopter Kit 10-DOF with Crazyradio<\/a>.<\/p>\n Since the Crazyflie\u2019s initial release, we\u2019ve listened to your feedback and updated the software.\u00a0 The firmware is now compatible with USB 3.0 which provides better stability, especially in windy conditions.\u00a0 It is still open source, and the Python drivers enable easy use.\u00a0 Plus, it can be compiled with an open source compiler.\u00a0 Another improvement is the Crazyflie Nano Quadcopter 4x spare motor mount<\/a> which we designed to counteract the intermittent balance issues caused by the arm of the PCB.\u00a0 Basically we consolidated the cylinder and created an extended motor arm to provide a more stable platform.<\/p>\n Our first accessory is the LiPro Balance Charger – iMAX B6<\/a>, a professional digital balance charger.\u00a0 It allows you to charge, balance, and discharge NiCd\/NiMH, Li-ion, LiPo, LiFe, and LiPb batteries in various cell sizes.\u00a0 This rapid charger comes with a high performance microprocessor, specialized operating software, and an illuminated lcd display.\u00a0 It is easy to use and allows you to charge each cell to a preset voltage.\u00a0 The charger monitors the progress in the display and notifies you when the battery has finished charging\/discharging.\u00a0 It even has a temperature sensor that you can put under the battery to make sure that it isn\u2019t overheating.\u00a0 It is a perfect companion for your rechargeable batteries like the Polymer Lithium Ion Battery \u2013 2200mAh 11.1V<\/a> or the Polymer Lithium Ion Battery \u2013 2200mAh 7.V<\/a>.\u00a0 Please note that the batteries must be connected to the charger with the provided connectors and be sure you get the polarity correct.<\/p>\n It is frustrating when power outlets are hard to come by.\u00a0 You\u2019ll definitely want to get yourself a Power Bank<\/a>.\u00a0 It is a portable power source that provides 10000mAh or approximately 2-4 hours of use, depending on your activity.\u00a0 Either plug your device in and run it off the bank or use it to charge your accessories.\u00a0 Since it has two USB ports, it can handle up to two items simultaneously.\u00a0 It is very durable and has built-in fail safe measures to make sure that it doesn\u2019t over charge or short circuit.\u00a0 As power from the bank is consumed, an LED indicator light will tell you how much remains.\u00a0 Then you can recharge it using the Micro USB cable that comes with it, a standard 5V\/1A DC power supply, or a 5V\/1A DC solar charger.\u00a0\u00a0 If you don\u2019t need as much power, we also have a Power Bank with 5,000mAh capacity<\/a>.<\/b><\/p>\n <\/p>\n <\/p>\n Have you ever been in the field with your RF Explorer<\/a> and found out that you need an adapter?\u00a0 It is disappointing to have to stop an experiment because some Wi-Fi antennas and cables aren’t SMA compatible.\u00a0 Now we have a whole slew of connectors to give you flexibility when connecting cables and antennas.\u00a0 First off is the SMA adapter SMA Plug to SMA Jack right angle<\/a> which converts your SMA Plug into a right angle SMA jack. \u00a0This comes in handy when a stand isn\u2019t available and the RF Explorer is horizontal.\u00a0 Next, we have an\u00a0RF Adapter RP-SMA Jack to SMA Plug straight-long version<\/a> which allows you to connect an RP-SMA (reverse polarity SMA)cable or antenna into the standard SMA plug on the Explorer.\u00a0 For HAM and two-way handheld radio antennas and devices that use BNC connectors, we have the SMA-BNC adapter SMA Plug to BNC Jack straight<\/a>. For those of you who need to connect lab grade RF bench tools, we have the SMA-N adapter<\/a>\u00a0which enables the connection between the Explorer\u2019s SMA jack and N connector size cables. \u00a0<\/b><\/p>\n As you know, RF cables are required when connecting a digital spectrum analyzer, like an RF Explorer, to other instruments or devices.\u00a0 We have two 50cm length RF cables that can handle frequencies up to 3 GHz and can guarantee signal integrity and reduce data loss:\u00a0 the SMA male to SMA female RF pigtail Coxial Cable RG316<\/a>\u00a0and the SMA male to SMA male plug pigtail cable RG316<\/a>. And if you need extra length for your connection, you can easily daisy chain two or more of these cables together.<\/b><\/p>\n Depending on what you\u2019re building, your projects have different voltage requirements.\u00a0 Unfortunately that usually requires owning a bunch of power supplies to meet your power needs.\u00a0 To cut down on the clutter you\u2019ll need an Adjustable DC\/DC Power Converter (1.25V – 35V\/3A)<\/a>.\u00a0 It will help accelerate prototypingbecause all of your power needs (3.3V, 5V, 9V, etc.) will be available in one easy-to-use power converter.\u00a0 Specifically, you will be able to convert voltage from 3.2V to 40V into 1.25V to 35V with a load current up to maximum 3A.<\/p>\n \u00a0<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n
