With one holiday period coming to a close, another looms on the horizon: Lunar New Year. That means three things in my mind: nice weather, a beautiful holiday with great food, and that I had better get all my orders for electronic parts for the next few months out immediately. In fact, I should have done it last month but I’m a bit closer to the source than many of you are.
In any case, Lunar New Year affects our ability to order neat gadgets at a time of year when some of us have received a little money to spend. So I thought I’d take a moment away from hacking to share with you how important this holiday is to much of the world so we can manage our expectations for quick global shipping accordingly.

Imagine it’s 1943, and you have to transport 1,000 P-47 fighter planes from your factory in the United States to the front lines in Europe, roughly 5,000 miles over the open ocean. Flying them isn’t an option, the P-47 has a maximum range of only 1,800 miles, and the technology for air-to-air refueling of fighter planes is still a few years off. The Essex class aircraft carriers in use at this time could carry P-47s in a pinch, but the plane isn’t designed for carrier use and realistically you wouldn’t be able to fit many on anyway. So what does that leave?
It turns out, the easiest way is to simply ship them as freight. But you can’t exactly wrap a fighter plane up in brown paper and stick a stamp on it; the planes would need to be specially prepared and packed for their journey across the Atlantic. To get the P-47 inside of a reasonably shaped shipping crate, the wings, propeller, and tail had to come off and be put into a separate crate. But as any reader of Hackaday knows, getting something apart is rarely the problem, it’s getting the thing back together that’s usually the tricky part.
So begins the 1943 film “Uncrating and Assembly of the P-47 Thunderbolt Airplane“ which has been digitally restored and uploaded to YouTube by [Zeno’s Warbirds]. In this fascinating 40 minute video produced by the “Army Air Forces School of Applied Tactics”, the viewer is shown how the two crates containing the P-47 are to be unpacked and assembled into a ready-to-fly airplane with nothing more than manpower and standard mechanic’s tools. No cranes, no welders, not even a hanger: just a well-designed aircraft and wartime ingenuity.

Ships at sea are literally islands unto themselves. If what you need isn’t on board, good luck getting it in the middle of the Pacific. As such, most ships are really well equipped with spare parts and even with raw materials and the tools needed to fabricate most of what they can’t store, and mariners are famed for their ability to make do with what they’ve got.
But as self-sufficient as a ship at sea might be, the unexpected can always happen. A vital system could fail for lack of a simple spare part, at best resulting in a delay for the shipping company and at worst putting the crew in mortal danger. Another vessel can be dispatched to assist, or if the ship is close enough ashore a helicopter rendezvous might be arranged. Expensive options both, which is why some shipping companies are experimenting with drone deliveries to and from ships at sea. Continue reading “Automate The Freight: Maritime Drone Deliveries”
However you sell your kits online, you’ll have to find a means of shipping them to the customer. For an online operation this unseen part of the offering is more important than any other when it comes to customer satisfaction, yet so many large players get it so wrong.
This is the final article in a series looking on the process of creating and selling a commercial kit from a personal electronic project (read all the posts in this series). We’ve looked at the market, assembling the kit and its instructions, and how to set up an online sales channel. In this part we’ll look at what happens when you’ve made the sale, how to get it safely to the customer and how to keep the customer happy after the sale by offering support for your products. We’ll also give a nod to marketing your site, ensuring a fresh supply of customers.

The United States Postal Service (USPS) is fixture of American life with its roots going back to colonial times. It operates the largest civilian vehicle fleet in the world, delivering about half a billion pieces of mail a day. As with any system of that size it’s always interesting to peek and poke at to see how it works. Unfortunately, it’s not as fun to hack as the phone system once was, but that didn’t stop some
hackers pranksters from giving it a go.
So how do you “hack” the mail? Simple, by testing its own rules. The folks at [Improbable Research] did just that and some of the results were interesting enough that we thought we would share them with you. They started with testing valuable items to see how honest USPS employees would be. First they attached a $20 bill to a post card. Yep, it showed up just 4 days later, and the money was still there. So they decided to see if sentimental items, that normally would be refused by the postal service, might skate through. They were able to send both an un-boxed single rose, and a human tooth (in a clear plastic box) without issue. Both arrived just fine, despite the rule that human remains are not allowed to be shipped via USPS. We’ll let you read some of the other items they tried.
So the next time you’re in Hawaii, forget about sending that generic, boring post card back home. Instead, slap some stamps on a coconut to let your friends know exactly how much fun you’re having.
With that said, we wouldn’t be doing our job looking out for our readers if we didn’t mention that before you try anything too outlandish, you can be fined for abuse of the postal system, even as a recipient. There was a fair amount of fallout when those guys sent a camera through the mail. Have fun, but not at someone else’s expense.
[Starhawk] had an old Pitney Bowes G799 postage scale that wasn’t working as it should. After years of faithfully measuring packages and cooking ingredients, the scale stopped working. At first it fell out of calibration. Then the power up sequence stopped working. The scale normally would turn on, light up the entire display, then change to dashes, and finally set itself to 0.0 lbs. In this case, it would get stuck at the dashes and never change to 0.0.
[Starhawk] ended up purchasing another duplicate scale from eBay, only to find that when it arrived it had the exact same power up problem. Using deductive reasoning, he decided that since the scale was broken during shipping the problem would likely be with a mechanical component. He turned out to be correct. The cheap momentary power button was at fault. When pressing the button, the contact would get stuck closed preventing the scale from zeroing out properly. [Starhawk] easily fixed his problem by replacing the switch.
Next [Starhawk] replaced the old scale’s LCD module with one from the new scale, since the old one looked to be on its way out. The scale still had a problem correctly measuring weight. [Starhawk] tried swapping the load cell from the new scale to the old one, but he found that the new load cell had some kind of problem that prevented the scale from zeroing out properly. The solution ended up being to use the newer “analog board” as [Starhawk] calls it. The end result was the old scale with two newer circuit boards, an older load cell, and a new power switch. Next time it might be easier to just build his own scale.
New to the Hackaday Store today is the Bulbdial Clock by Evil Mad Scientist Laboratories. I’ve had my eye on this kit for years and finally pulled the trigger after visiting [Lenore] and [Windell] at their shop a few weeks back. Assembling the beautifully-engineered kit was a delight, and I have a handful of hacks I’d like to try out — some of which I mentioned in the product description.
Free shipping based on order price
We always listen to what the Hackaday community has to say. After receiving several requests for better international shipping prices we came up with a way to ease the pain for orders no matter where they are headed. All domestic orders totaling $25 or more now receive free shipping. All international orders totaling $50 or more now receive free shipping.
Is there anything else you’d like to see different about the store? How about a hackable product you think we should stock? We’re listening via the store contact form.
