Guerrilla guide to CNC machining, mold making, and resin casting. Table of contents: 1. Introduction A quick overview of what this guide has to offer to DIYers looking for a CNC mill - and to those who have already settled on low-cost 3D printing or any other rapid prototyping technology out there. 2. Setting up a CNC mill Pointers for selecting a low-cost, hobbyist-friendly CNC mill, stocking up on tools, and keeping the whole setup in great condition for many years to come. 3. Tips for finding the right CAD and CAM software - plus a quick but in-depth tutorial on three-dimensional modeling. 4. Advanced, workshop-safe methods of producing durable, high-performance parts of almost any kind - from tough rubbers to bullet-stopping composites. 5. Advice on how to build a library of prefabricated components for all sorts of electromechanical work. 6.
A no-nonsense primer on mechanical engineering, gear design, and power transmission layouts. 7. The sort of things you probably need to know to avoid setting yourself on fire. 8.
ESP8266 WiFi Throwies. A few years ago, someone figured out you can take an LED, a coin cell battery, and a magnet, tape them together, and throw them on every conceivable metallic surface. This was the creation of LED throwies, and the world was much worse off for its invention. With the ESP-8266 WiFi module, we have a tiny, tiny device with a WiFi radio, and just enough processing power to do something interesting. What does that mean? WiFi throwies. [Andreas Reischle] stuffed an ESP-8266 WiFi module and a lithium cell inside a weatherproof controller loaded up with magnets. On its own, these wouldn’t do much, but with the right combination of software, this little magnetic box can serve as an access point, serving up small JavaScript games to anyone who connects.
The software is based on the NodeMCU firmware and features a web server and a DNS server. It’s much better than polluting the world with LEDs and lithium; this one has Hunt the Wumpus on it. Thanks [Oliver] for the tip. Spiral Cut a Wooden Dowel Using a Table Saw. Laser Cut Foam Inserts for Tool Boxes. This is my first Instructable. Any constructive criticism in the comments will be gratefully accepted. Lately I'm doing more machining at TechShop SJ. As a result, I've been carrying a lot of cutting and measuring tools back and forth from home. Many of the tools have precisions surfaces or are somewhat fragile. Remarkably, some of these came with no protective container.
So, I decided to make some. All of the work in this Instructable was done at TechShop SJ, my home away from home. This Instructable is all about finding the best, least expensive foam from which to laser cut inserts to hold the tools safely in their boxes. Since all my projects get out of hand almost immediately, I also did some foam inserts for one of the tool boxes in my home shop. Using inserts in tool boxes to protect and organize tools is called "shadowing" in the aerospace industry. Fan Powered by any Heat Source. How to build your own portable thermoelectric device with a quadcopter motor.
This project might not have an electrifying impact to the world but it´s a baby brother to my first instructable (Thermoelectric Fan) and just had to be built. It´s much smaller than most similar projects and the top power device can be detached from the lower heat source base and be used as experiment in other areas. What does it do? It converts heat energy into kinetic energy, looks nice and sounds awesome! Concept: It uses a thermoelectric generator module (TEG) to power a motor with a fan. Experimental Areas: Almost any heat source with enough temperature can be used to power the motor and this makes this small device easy and fun to experiment with. Specifications: Size base: 56x64x40mm Size power device: 56x56x40mm (including fan) Size total: 64x64x79mm Weight base: 27g Weight power device: 85g Weight 3D print: 2.7g Weight total:114.7g Cost: ~12$ Construction.

Some good ideas there, but failed execution. It would need to have a rotating disc in front of the round hole so that only a small amount of food is served. (As opposed to that elevator platform in the elevator shaft thing, that let all the food out at once) Needs to be plastic or metal if you want to keep a hungry cat out.
Personally speaking. Build Your Own Electronically Powered Self-Watering Plant System. For those that want an off-the-shelf option I bought one of these and I love it for the most part: The reservoir is 6.6 gal so it is huge which is a good and bad thing. Also it is gravity based so somehow you have to manage to lift the 6.6 gal box above all your plants. Might seem like a lot of negatives, but this has saved me so much time since I bought it about 6 months ago before a 2 week vacation. 33 DIY Gifts You Can Make In Less Than An Hour.
