Ask Hackaday: Troll physics edition

posted Dec 19th 2011 12:01pm by
filed under: Ask Hackaday

[Martin] sent in two videos he found while cruising the tubes. The first video is a simple circuit with a resistor, three switches, and three LEDs. All the components are soldered together right in front of the camera. When a battery is connected, turning the first switch on makes the first LED light up. Turning the second switch on makes the second LED light up, and the same thing goes for the third switch and LED. Obviously we’re dealing with powers that are incomprehensible with even several cups of coffee.

The second video features the same resistor/switches/LEDs, this time in a parallel circuit. Turning on the first switch makes the first LED light up, and the second switch makes the second LED light up. Truly we are dealing with an expert in troll physics.

This is probably something really benign and uninteresting, but it sure is enough to wake up enough brain cells on a Monday morning. We’re not going to hypothesize, so check out the comments where we expect the correct answer to be.

Ask Hackaday: Organizing a growing collection of electronic odds and ends

[Tim] wrote in, lamenting a problem that many of us can likely echo. Over the years, he has acquired all sorts of small electronic parts and components, along with tools and accessories – all of which are starting to crowd his workspace. He says that most of his stockpile is being stored in a tackle box, but it’s getting unwieldy and he would like to find a better way to organize things.

Yours truly suffers from the same sort of situation. It’s mostly a result of being a tad bit lazy, while conveniently finding alternative storage containers for my electronic odds and ends. My workbench is strewn with plastic snack baggies (for screws, not ESD-sensitive bits), Glad-Ware containers, Eclipse gum packages, and old plastic baby formula tubs for larger items. While I’m certainly doing my share to reuse plastic packaging, I am aware that it’s not exactly the best organization methodology.

This topic does come up pretty often, and even though we’ve talked about it on several occasions, people still like to hear fresh feedback from their peers. If you have some clever organization tips, or a novel way of storing your electronics components, be sure to share them in the comments!




Project hosting, a common question

Ok, you’ve finished your project, you’ve taken great notes along the way and photographed every step. Now you want to share. Where will you post it? There are a lot of options out there, private hosting, Hackaday,  instructables, and tons of others. How can you decide? Here are some handy break downs to help you figure it out at a glance.

Each has its own pros and cons. Take a peek at our list after the break and share your own as well.

A Black Box Mystery

posted May 15th 2010 3:00pm by
filed under: Ask Hackaday

One of the members of the SomethingAwful forum recently found a black project box on the street (as seen above), with no idea what the thing did. After (hopefully) making sure there were no explosives, [noapparentfunction] posted a picture online to see if someone could figure it out. According to them, this is what the chips are labelled as:

Center black IC: MICREL Y22758C; 0417
Long white DIP switch IC: CTS 206-12; T438
Small black microcontroller on right: 12C508A; 04/P1V6; 0437. Has a tiny “M-inside circle” logo.

From our experience, we recognized the PIC on the board, but without some more photos, it makes this mystery a little more interesting.

Right now their best guess is a garage door opener of some kind because of the 12 DIP switch part. Any HAD readers willing to investigate and weigh in? The game is afoot!

Answers.hackaday.com is LIVE

filed under: Ask Hackaday

Quick, go to answers.hackaday.com and sign up for an account. Ages ago, we announced that we would be bringing a community driven question and answer system to Hackaday. We eventually got tired of waiting for the feature to be provided and improvised. Well, the wait is over. You can now post your own questions and answers. Go nuts, post away, but remember to be respectful. We’re still figuring out this system ourselves, so be patient with us as well.

Be warned, we’re going to be pretty strict on trolling.

It is worth noting that there is a money system integrated into it. This means that you can offer a real reward for answers to your questions. You certainly don’t have to though.

Ask Hackaday: Now a regular occurrence

posted Mar 21st 2010 11:00am by
filed under: Ask Hackaday, news

A while back, we announced that we would be bringing new features to Hackaday. One in particular that garnished a lot of interest was our question answer type thingy. Well, in case you hadn’t noticed, that has not happened yet. Without divulging too much into the secret machinery that lies underneath Hackaday, I’ll just say that we(the writers) don’t necessarily have control over all aspects of the site. An example would be the copyright. Yes, we finally got it updated. Thanks for all of your emails. No, none of us had access to that part of the site, so don’t bother letting us know how simple that change should have been.

We are as eager as you to see some good ideas and good feedback flowing through this site, so we’re going to start a regular post, entitled “Ask Hackaday”. This isn’t entirely new, we’ve done it before actually. This is just to let you know that we intend to do it regularly, and to set some ground rules.  ”Ask Hackaday” will mostly center around you, our readers, and your ideas. We will publish a question, and possibly our thoughts, but the main content will be your responses. We have a huge collective of intelligent creative readers and it would be a shame not to tap into that pool of knowledge.  When you are offering an answer, be thorough, give details, and please be kind.

Send your questions to askHAD@hackaday.com for consideration. They will be chosen based on a complicated system of random number variation involving furry woodland creatures and how we feel at the moment that we read them. Do not get offended if you question does not get published. We get tons of questions already and we don’t intend to publish them all.




Hack a Day serves up fresh hacks each day, every day from around the web as well as hacking related news.
