Brilliance by Design: Resin-inlaid Wood A non-jewellery post, for a change. We were running a bit short on shelving in the kitchen and wanted somewhere we could store all the preserves we're going to make from the garden this year, so we went to the timber yard to see what they had. They had this, 155cm long piece of chestnut. It was pretty heavily cracked and pitted, with knotholes and so on. But, I had a plan. First job, seal off the holes from the bottom, using aluminium plumber's tape. Make sure the wood is level, otherwise you'll end up with wonky resin bits. Now it's time to mix the resin. You know when I said this isn't going to be a traditional inlay? So, pour it in, and wait. However long you think it's going to take, leave it longer. The overpour around the edges where the resin has soaked into the wood is going to be a pain to remove. More sanding. View from the end. Now it's time to get these up. And, they're up. Now, in darker conditions, you can really start to see the glow resin in action. Wall robot approves.
Which Programming Languages Can You Use With Arduino? Ready to try something different with your Arduino? You needn’t be confined by programming in C. Take these alternative languages for a test drive. The Arduino IDE is core to the ethos behind the project — it’s a UI that attempts to turn the daunting task of learning a programming language into something that anyone can take a stab at. Just as there are an enormous range of different coding languages, there are a multitude of different reasons that you might want to take a different approach to programming. The important thing is to find a language that speaks to you and the goals that you’re looking to achieve. ArduBlock Arduino is built around a straightforward programming language that’s meant to be welcoming to newcomers — but if you’re really short on experience, it might be worth trying a tool like ArduBlock. It’s great for younger users, but don’t think that this is ‘Arduino for Kids’. ArduBlock is a downloadable tool that runs as an overlay to the official Arduino IDE. Python
3D printable 'Drone It Yourself' kit turns any object into an UAV Jul.6, 2013 Home-built drones are very popular among hobbyists with backgrounds in electronics and robotics. Jasper van Loenen, an independent designer working in the field of interaction/information, design and art, wanted to make the design simpler so anyone can make their own. Van Loenen has created a custom DIY (Drone It Yourself) v1.0 kit that turns any object into an unmanned aerial vehicle, simply by attaching four motors and a control unit – no technical know-how needed. The plastic parts for this 'Drone it Yourself' project have been 3D printed in ABS. The control unit contains a receiver, four ESCs, a bluetooth module and an OpenPilot CC3D flight controller. Both the original files and the printable STL files are available here.
MDI Project Wiki - MDI Project Wiki These pages document the development of an ongoing research on generating and manipulating sound and imagery through rudimentary and easily accessible, open-source hardware, as an alternative (not opposed) to the use of prepackaged hardware/software solutions more common in design practice.

Introduction to hobbyist Lock picking Aka: LockSport - All Lock picking gets a bad wrap. When most people hear the phrase, it congers images of illicit activities and unscrupulous personas. But really, when it comes to petty larceny the most effective strategy isn't going to be lock picking. Destructive entry: bricks, angle-gringers, bolt cutters and sledgehammers are the order of the day. The time it takes to finesse a lock open isn't something most criminals would be willing to commit themselves too (or so I'd imagine). The information to follow will strictly pertain to the budding hobbyist/enthusiast: how to get into "Lock-sport," as logically and cost-effectivly as possible. Any and all sites/products mentioned herein I've personal experience with and have found either the information therein or merchandise supplied to be of merit sufficant to warrant their inclusion in this article. Hope you enjoy, Cheers. PS: I've included a short glossary of terms in the final step in this instructable just in case.
Understanding TRRS and Audio Jacks - Cable Chick Blog Learn about the varieties of audio jack and how to identify them, plus discover why one TRRS cable won't work for all your AV needs. We know them. We love them. To keep things easy, we'll use the term plug for male and socket for female whenever we need to be specific, and we'll pretend jack is genderless. Once upon a time, what we now see as stereo jacks or headphone sockets were used in the telephone switchboards of the 19th century. T = Tip, R = Ring, S = Sleeve These days it's generally easier and more accurate to refer to each type by their Tip/Ring/Sleeve configuration to avoid any misunderstanding, especially when balanced audio is taken into account. Professional-grade audio leads used for live performances sometimes have their own sets of rules (balanced/unbalanced/powered). Even now, the most common place to find an audio jack is on your MP3 player or personal computer. In some cases, you could swap the RCA ends around and still get picture and audio, but not always.
Learn Electronics and Arduino Just By Watching These Videos Advertisement Learning to program your own electronics is empowering and rewarding, but it can be difficult to get started without guidance. We’ve rounded up the best videos, YouTube channels and online courses to get going. What is Arduino? Arduino is a popular open-source microcontroller, meaning a small computer with programmable inputs and outputs. There’s a lot of great basics that come in a starter kit, and you can also buy sensors that can hook up to Arduino to track temperature, light, proximity, and more. Still not sure if you want one? I was lucky to have a professor in university teach a course on programming in Arduino. YouTube Channels about Arduino Tutorials for Arduino by Jeremy Blum Typical video length: 15 to 30 minutes. Jeremy Blum has been educating people on how to use Arduino for years now. The first video is a fantastic introduction to the scope of Arduino, or a refresher if you’re coming back to Arduino from some time away. EEAwesome Arduino Video Tutorial by Arduino
Electronics made easy Resistors are simple: they limit the amount of current allowed through a circuit. Resistors are color coded to make it easier, and can have four, five, or six colored bands. Resistors are measured in Ohms. To find the resistance of the four-band resistor: look at the resistor, make sure the side that has a silver or gold is to the right (there might not be a band with one of these colors, make sure the side that has no band is to the right). now you simply read it. write down the first value write down the second value the third number tells you how many 0's to add to the number the fourth number tells you the tolerance. black=0 brown=1 red=2 orange=3 yellow=4 green=5 blue=6 Purple=7 gray=8 white=9 Silver=10% tolerance Gold=5% tolerance In the picture the resistor is red green red gold, so that would be 2500-5%.
High-Range Wireless Power How we simulated the design We simulated and optimized the design in a 2-D mangetostatic simulator, and with SPICE. We used the free 2-D mangetostatic simulator called Infolytica. You can download for free here: We used the free SPICE simulator called LTSPICE. Design files for both simulators are attached. Discussion This design uses resonant magnetostatic power transmission. We simulated & optimized the coil with Infolytica's 2-D magneto static simulator. Magnetic Simulated Values: Transmitting Coil = 4.35mHReceiving Coil = 0.105mHMutual Inductance = 9.87uH. We then took those numbers and fed them into SPICE to simulate the electrical characteristics. You can download the simulation files attached, and try to make your optimizations and measurements! Also attached are field plots, that show the magnetic field produced by the coils.
Cheap precision drill stand - All I came at this solution after taking care at cost (if your DIY is very expensive it's better you buy it!), efforts (all my hardest project are still waiting to be completed), parts availability (if you have to wait shipment for each part of the design you'll forget for how you needed them, especially with Italian post service) and functionality. The slide is a "macro rail" for photography which you can find on eBay at about 10$, but I already had a couple of them. The other parts you need, other than the drill, are only: a strong spring (but also a big elastic is good) some wood boards some screws a nail 5 inch of a little aluminium cilindrical bar (as the ones of the TV antennas) a wood base and two inches of aluminium pipe (this also isn't so essential) Oh yes, and also a nice gum-covered toothbrush!
