Curious Inventor Blog - Eagle vs KiCad Inspired by Steve Chamberlin’s post evaluating kicad vs eagle for someone new to both, here are some more opinions from the perspective of someone who uses both equally, (about 20 projects for both), but is certainly not an expert at either.Summary: Eagle is more straightforward, has better library support of out of the box, and better community support (ladyada, sparkfun, etc.).Kicad is free, and is maybe 1 or 2 revisions from being great. Click the entry for our list of pros and cons: Here is a random list of pros and cons: libaries: Eagle has great library support out of the box; sparkfun and ladyada’s libraries are great. Dealing with libraries in eagle is a little more straightforward. Conclusion: This is by no means an exhaustive list (more experienced users please weigh in!)
Computer Power Supply to Bench Power Supply Adapter Step #13: Add Labels For Each Pair of Terminals PrevNext To help keep track of the different voltage outlets, I labeled each pair of terminals. You can print out a simple label and attach it to the top face of the housing between the positive and negative terminals. Wings 3d How to Convert a Computer ATX Power Supply to a Lab Power Supply Edit Article Edited by Abizarl, Krystle C., Jack Herrick, Vertent and 42 others Computer power supplies cost around US$30, but lab power supplies can run you $100 or more! By converting the cheap (free) ATX power supplies that can be found in any discarded computer, you can get a phenomenal lab power supply with huge current outputs, short circuit protection, and reasonably tight voltage regulation on the 5V line. On most power supply units (PSUs), the other lines are unregulated. Ad Steps 1Look online or at your local computer store for an ATX computer power supply, or dismantle an old computer and remove the power supply from the case.Ad 2Unplug the power cable from the power supply and turn off the switch on the back (if there is one). 13 Plug the power cable into the back of the power supply and into an AC socket. Tips You can use your power supply 12V output as a car battery charger! Warnings If you suspect the power supply is damaged, do not use it!
Home | YafaRay Raspberry Pi as an Ad Blocking Access Point This tutorial will show you how to use your Raspberry Pi as a WiFi access point that blocks ads by default for any devices using it. This is really neat in that it would work for your Android or iOS device, your Xbox 360, TiVo, laptop, and more without needing to customize any of those devices other than to use your Raspberry Pi as the access point for WiFi. Using an ad-blocker can be useful for conserving bandwidth, helping out low-power devices, or for keeping your sanity while browsing the web! I do suggest whitelisting your favorite ad-supported sites so that you can continue to support them (this tutorial shows how to do this as well). It's not easy keeping up with those wily ad serving companies so we'll also setup a way to keep your ad blocking lists up to date as part of this tutorial. I used many pages as inspiration in order to set this up, including, but not limited to:
