When building a one-off DIY project, appearances tend to be the least of our priorities. We just want to get the device working, and crammed into some project case. For those that like to build nicer looking prototypes [JumperOne] came up with a slick method of building a custom front panel for your DIY project.
The first step is to get the dimensions correct. You CAD tool will generate these from your design. [JumperOne] took these measurements into Inkscape, an open source vector graphics tool. Once it’s in Inkscape, the panel can be designed around the controls. This gets printed out and aligned on a plastic enclosure, which allows the holes to be marked and drilled.
With the electronics in place, the front panel gets printed again on a general purpose adhesive sheet. Next up is a piece of cold laminating film, which protects the label. Finally, holes are cut for the controls. Note that the display and LEDs are left covered, which allows the film to diffuse the light. The final result looks good, and can provide all the needed instructions directly on the panel.

Gather, boys and girls, while we take a moment to talk about submitting projects via the Hackaday Tips Line. Come across something really cool that you think deserves a mention on our page? Let us know about it! Did you yourself make something really cool? Tell us about that, too! It doesn’t matter if it’s a project that’s been sitting on some dark corner of the Internet for a few years. If we haven’t seen it yet, we want to.
Don’t think your project is good enough for Hackaday? You’re probably too self-critical. We’re after hacks: it’s the idea that counts. Not polished? No problem. The only thing that needs to be complete is your description of the hack.
Stick with us after the jump; we’ve got plenty of tips about tips to help you out.

[Diato556] made a really cool single-phase induction motor with parts mounted on Duplo blocks. He has posted an Instructable where he uses these modular parts to demonstrate the motor and the principles of induction as described after the jump.

Not long ago the Shapeoko 2 came out. In case you missed it, the Shapeoko 2 is the 2nd generation bench-top CNC Router of the namesake. All axes roll on Makerslide and v-wheels. The X and Y axes are belt driven, power is transmitted to the Z axis by lead screw.
As with most products, there will be people who must hack, mod or upgrade their as-received item. If you are a regular Hackaday reader, you are probably one of those people. And as one of those people, you would expect there have been a few individuals that have not left this machine alone.

This is a mod more than a hack but any time you can alter original equipment to maintain its usability is a win-win scenario for you and the environment. Everyone has or knows somebody that has a vehicle and most vehicles nowadays have some type of hatchback or hood where the support solution is gas filled struts. Inevitably these gas filled struts fail with age and the failure is accelerated in hotter or colder climates. If you ever had to replace these items you know they can cost a minimum of $20 to as much as $60 a piece. Most vehicles require two, four or even eight of these costly little devices.
[Brian] from Briansmobile1 YouTube channel documented three simple and low cost solutions. We all probably know of the vice clamp solution but that is cumbersome and still an expensive solution which is not always very handy or fast. Another solution is to cut a piece of rubber hose in a kind of special way so it is easy to put on and take off the shaft and dangles from a string so it’s always available. The best solution was to use a hitch pin also connected to a string or wire. To make the hitch pin work you have to grind a couple of notches on either side of the lift shaft at just the right spot so the pin can be snapped on and prevent the shaft from retracting at your selected height.
We are sure these solutions will come in handy at some time in most everyone’s driving career. Just after the break we will link to all three of [Brian’s] handy videos on gas strut fix solutions. And if you do your own automotive repair we can definitely recommend [Brian’s] channel of over 600 vehicle repair and maintenance videos which normally come with a dose of philosophy and humor.

We’re back and this time talking about Safe Operating Area also called Safe Area Operation (SAO) which is short for the combination of things that can conspire to ruin your design. We also talk about helicopters.
Why take all of this time to discuss SAO you might ask, and what is that business about helicopters? Depending on the design there may be quite a bit of tedious math involved and sometimes there is just no avoiding it. Alternatively if you can get a feel for when math is and is not critical (based on design choices), it should be easier to get your next project up and running while still obeying the rules of the road.

Let’s face it: most of us have trouble getting out of bed. Many times it’s because the alarm isn’t loud enough to rouse us from our viking dreams. [RimstarOrg]’s homeowner’s association won’t let him keep a rooster in the backyard, so he fashioned a piezoelectric crystal speaker to pump up the volume.
[RimstarOrg]’s speaker uses a Rochelle salt crystal strapped to a bean can diaphragm. In his demonstration, he begins by connecting an old clock radio directly to the crystal. This isn’t very loud at all, so he adds a doorbell transformer in reverse. This is louder, but it still won’t get [RimstarOrg] out of bed.
Enter the microwave oven transformer. Now it’s sufficiently loud, though it’s no fire bell alarm. He also demonstrates the speaker using a piezo igniter from one of those long barbecue lighters and a crystal radio earpiece. As always, the video is after the jump. [RimstarOrg] has a lot of relevant linkage in the summary so you can learn how to grow your own Rochelle crystals.
