Recently, the development of a tiny chip called the ESP8266 has made it possible to interface any type of microcontroller to a Wi-Fi AP. The ESP8266 is a low-cost tiny Wi-Fi chip having fully built-in TCP/IP stack and a 32-bit microcontroller unit. This chip, produced by Shanghai based Chinese manufacturer Espressif System, is IEEE 802.11 b/g/n Wi-Fi compatible with on-chip program and data memory, and general purpose input-output ports. Several manufacturers have incorporated the ESP8266 chip in their hardware products (e.g. ESP-xx, NodeMCU etc) and offer these products as a means of connecting a microcontroller system such as the Android, PIC microcontroller or others to a Wi-Fi. The ESP8266 is a low-power chip and costs only a few Dollars. ESP8266 and MicroPython – Coding Cool Stuff is an introduction to the ESP8266 chip and describes the features of this chip and shows how various firmware and programming languages such as the MicroPython can be uploaded to the chip. The main aim of the book is to teach the readers how to use the MicroPython programming language on ESP8266 based hardware, especially on the NodeMCU. Several interesting and useful projects are given in the e-book (pdf) to show how to use the MicroPython in NodeMCU type ESP8266 hardware: Project “What shall I wear today?”: You will be developing a weather information system using a NodeMCU development board together with a Text-to-Speech processor module. Project “The Temperature and Humidity on the Cloud”: You will be developing a system that will get the ambient temperature and humidity using a sensor and then store this data on the cloud so that it can be accessed from anywhere. Project “Remote Web Based Control”: You will be developing a system that will remotely control two LEDs connected to a NodeMCU development board using an HTTP Web Server application.

The SQ series of handsfree PCBite probes from Sensepeek are insulated, come with included color-coded cable holders and have a lower point of gravity making them even more stable compared with the original SP series of probes. All the loved features of handsfree measurement, exchangeable fine pitch spring tipped test needle and the minimalistic design is maintained to make traditional sized and handheld probes obsolete. Features All handsfree probes from Sensepeek makes instant measurements or long triggering sessions a breeze. No more soldering wires to connect your probe or complicated tools to setup, just positioning the probe needle on any test point or component in the signal path and release. Saves time and frustration during development, verification and repairs. The minimalist design and the spring-loaded test needle makes it possible to simultaneously measure on fine pitch components and nearby signals. Both length and weight of the SQ probes are perfectly balanced to be used with the included PCB holders and base plate which is a must for handsfree function. The probe holder comes with a powerful magnet in the base, as for all PCBite probes and holders which makes the probe easy to place and reposition. The SQ series of probes can be used handheld without the probe holder as they have an insulated grip but their full potential is used when measuring handsfree. One side of the included baseplate is matte and the other is mirror polished. The mirror polished surface makes it easy to see components on the circuit board underside. For added protection during measurement the included insulation cover can be mounted on one of the surfaces. Included 4x PCBite PCB holders 1x Set of yellow insulation washers for the PCB holders 1x Large Base plate (A4) 1x Insulation cover for the base plate (A4) 1x Micro fiber cloth 4x SQ10 probes and pin tipped test needles (black) 2x Banana to dupont test wires (red/black) 5x Dupont to dupont test wires 1x Set of cable holders (4 colors) 4x Extra test needles Downloads User guide (PCBite kit) User guide (SQ10 probes)

The 8x10" iFixit Magnetic Project Mat catches and securely holds screws as you pull them out of a device. Now you can stop worrying about keeping track of all the loose screws and focus on your repair. Screws and small parts will remain right where you left them. For laptops with hundreds of screws, use the whole mat as a screw guide and keep careful location notes. Included is a pen — made by Staedtler, producer of top-of-the-line pens and pencils for artists and architects — that was specially designed for the Project Mat. The Lumocolor Correctable pen resists smears and won't wipe away with a casual brush of your hand. When your repair is complete, use the eraser tip or a dry cloth to wipe the ink away clean. Kenmerken Organize all your small parts while you work on a device. The dry-erase surface lets you keep notes and location sketches. Reduces reassembly time by up to 40% while preventing errors.
