What are card beams, you may ask? They are the building toy that allows you to build gravity-defying houses of cards with the help of friction, gravity, and two types of beams - the cap and the connector.

Machine PCB assembly in the USA Skills Offered / Adafruit Jobs Board We are offering affordable PCB assembly in the good old USA. We purchased a MannCorp MC385-1V1 pick-and-place assembly machine for our retail and wholesale operations late last year, but our particular market will be slow for the next 6 months. We’re looking for an excuse to keep this wonderful pick-and-place machine running over the summer (it’s a shame to have it sitting there collecting dust). We are hoping to find designers who have prototype, small batch, or low to medium volume needs. Please contact us if you are looking for machine PCB assembly in the USA. Rates are negotiable – we don’t have a rate sheet because we’re new to doing contract work and it seems that every job is different. We have placed SMT’s down to and below 19 mil pitch. Machine can easily place 0402′s and 010005′s (we purchased all the bells and whistles for this machine). We can pick up reel parts, cut tape parts, waffle packs, loose parts. Our stencil printer is a manual stencil printer, we have printed SMT’s down to and below 19 mil pitch. We can handle single boards, simple matrix panels or complicated matrix panels up to about 14″ x 12″. We can do lead and lead-free. We are rather informal so we feel we are a good fit for designers who are on a budget but don’t want to send their pieces overseas. Looking forward to working with you on your project. Learn More

We love the look, and most especially the gait, of [Theo Jansen's] walker designs. We don’t fully understand them or the math behind them. But that could change if we spend enough time studying [Aaron Birenboim's] body of work. He wants to incorporate the legs in a project so he’s been trying to optimize the Jansen leg design. The calculations are delivered in a source code package available from his site. To make heads or trails out of the numbers you need a way to visualize them. He has provided that as well in the form of a MATLAB script which shows leg piece design and can even spit out an animated .gif file of the virtual legs in motion. If you have no idea what we’re talking about make sure to check out [Jansen's] original creations. We’re also excited to read more about the Klann and Ghassaei linkage designs which [Aaron] talks about in his post. Filed under: 3d Printer hacks

Jennifer was one of my first patients as a new doctor, and she came to see me about an unintended pregnancy. A single mom to a rambunctious 5-year-old girl, Jennifer was struggling economically and battling depression. We talked about the options available to her: continuing the pregnancy and preparing to parent another child, offering the baby for adoption or having an abortion. She chose to continue with the pregnancy, and I worked with her over the following months as she struggled with the discomforts of pregnancy, excessive weight gain and the anxiety of having to raise two small children on her own.

Renting a car is something that many people do when they go on vacation. But most people don’t realise all the potential traps and pitfalls that can be avoided when renting a car. Having worked for a car rental company, I’ve come across lots of hacks that you can use to save time, save money, and generally make the whole process of renting a car a lot easier. Today I’m going to share 21 rental car tips with you; I guarantee there will be at least one tip you hadn’t thought of in the list! Ditch the travel agent Have a think about where travel agents earn their money. They work on commission. That means they get a certain percentage of the booking amount, and they may get kick-backs from certain suppliers. The more expensive your booking is, the more money they make. Booking car hire by yourself is so easy, and only takes a couple of minutes. Book early to save Just like airfares and accommodation, prices for rental cars usually increase as you get closer to the date of service. This is especially true around holidays such as Christmas and Easter. Because demand is so high and rental car fleets are limited, the suppliers can charge just about whatever they like and know that people will still be desperate enough to book. Booking far in advance means you’ll get the best possible rate, as well as choice of the full range of cars. Compare, contrast, and find a deal Comparison websites are a great way to book car hire. Using one of these comparison sites, you can compare all the major car rental suppliers against one another on the same screen, and find the cheapest deal. There are plenty of comparison sites around, just make sure you use one that doesn’t charge any booking fee or cancellation fee so you’re not out of pocket if you happen to find a better deal later on. My favourite is probably VroomVroomVroom because they offer a lowest price guarantee. They also send you a confirmation SMS so you don’t need to bother with paperwork when you pick up the car. Airport rental centers cost more Did you know that the price of rental cars at the airport is way higher than that city depot, even for the same supplier? It’s partly because airports charge the rental car suppliers a huge amount for renting the car spaces and desk space inside the terminal. They also charge customers more for the convenience. If you’re renting a car for just a day or two, it might not make much of a difference in your total bill. If you’re renting for a week, it could mean huge savings. Compare the price for airport and downtown locations to see if it’s worthwhile getting other transport from the airport to the city and picking the car up there instead. Don’t forget to fill up! Rental companies will charge you a fortune if you don’t fill up the car before taking it back. They’ll charge you up to double the regular pump price, and some will even add an “administration” fee on top! Fill the car up before you drop it back, and don’t forget to keep the receipt! In the case of a dispute, the time/date and amount on your receipt is evidence that you filled the car up. Consider the environment I’m not just talking for the environment’s sake, either. Choosing an economical car or hybrid can save you lots of money when it comes to refuelling. Sure, that giant Cadillac might look nice, but if you’re looking to save money then maybe a Civic would be the smarter choice. Don’t pay in advance Book through a supplier or comparison website that doesn’t require any payment up front. If you find a better deal somewhere else, or if something else comes up and you need to change your plans, at least you won’t be stung with a cancellation fee! It also means you can make a few bookings and choose the one that’s best for you as the date gets closer. By booking early you can lock in good prices, and just cancel the ones you don’
