Maplin For Salemaplin-sale-featuredjennylist

Sun, 25 Feb 2018 06:00:00 +0000

If you are an American Electronics Enthusiast of a Certain Age, you will have misty-eyed reminiscences of the days when every shopping mall had a Radio Shack store. If you are a Brit, the name that will bring similar reminiscences to those Radio Shack ones from your American friends is Maplin. They may be less important to our community than they once would have been so this is a story from the financial pages; it has been announced that the Maplin chain is for sale.

Maplin started life as a small mail-order company supplying electronic parts, grew to become a …read more

This 3D-Printed Robotic Vacuum Sucks3dvac_feattomnardi

Sun, 25 Feb 2018 03:00:00 +0000

After you’ve taken a moment to ponder the turn of phrase used in the title, take a look at this scratch-built robotic vacuum created by [theking3737]. The entire body of the vacuum was 3D printed, and all of the internal electronics are off-the-shelf modular components. We can’t say how well it stacks up against the commercial equivalents from iRobot and the like, but it doesn’t look like it would be too hard to build one yourself to find out.

The body of this rather concerned-looking robot was printed on a DMS DP5 printer, which is a neat trick as it …read more

Delightful Electromechanical Build Of A Jet Engine ModelMechanical/electrical jet engine modelstevenduf

Sun, 25 Feb 2018 00:00:00 +0000

[InterlinkKnight]’s jet engine model is a delight to behold and to puzzle out. Many of us have been there before. We know how to build something, we know it’s not the most up-to-date approach, but we just can’t help ourselves and so we go for it anyway. The result is often a fun and ingenious mix of the mechanical and the electrical. His electric jet engine model is just that.

Being a model, this one isn’t required to produce any useful thrust. But he’s made plenty of effort to make it behave as it should, right down to adding a …read more

These Small PCBs are Made for Model RocketryModel Rocket PCBs Featureddp2cnk

Sat, 24 Feb 2018 21:00:00 +0000

Model rocketry hobbyists are familiar with the need to roll their own solutions when putting high-tech features into rockets, and a desire to include a microcontroller in a rocket while still keeping things flexible and modular is what led [concretedog] to design a system using 22 mm diameter stackable PCBs designed to easily fit inside rocket bodies. The system uses a couple of 2 mm threaded rods for robust mounting and provides an ATTiny85 microcontroller, power control, and an optional small prototyping area. Making self-contained modular sleds that fit easily into rocket bodies (or any tube with a roughly one-inch …read more

Fully 3D Printed Nerf Thirst Zapper3dzapper_feattomnardi

Sat, 24 Feb 2018 18:00:00 +0000

In case you weren’t aware, there is a whole community out there that revolves around customizing NERF guns. In that community is a subculture that builds their own NERF guns, and within that group is a sub-subculture that 3D prints NERF guns. So next time you are contemplating how esoteric your little corner of the hacking world is, keep that in mind.

Anyway, [Wesker] is currently making his way in the world of 3D printed one-off NERF guns, and has unveiled his latest creation: a fully 3D printed “Thirst Zapper” from Fallout 4. Except for the springs, each and every …read more

Microchip Introduces Tiny Cheap Linux ModulesMCHIPboardbrianbenchoff

Sat, 24 Feb 2018 15:00:00 +0000

Linux is in everything these days, and that means designers and engineers are crying out for a simple, easy-to-use module that simplifies the design of building a product to do something with Linux. The best example of this product category would probably be the Raspberry Pi Compute Module, followed by the C.H.I.P. Pro and its GR8 module. There are dozens of boards with Allwinner and Mali chips stuffed inside that can be used to build a Linux product, and the ‘BeagleBone on a Chip’ is a fantastic product if you need Linux and want to poke pins really, really fast. …read more

You’ve Never Seen A Flipping Eyeball Like This One!flip-eye-featuredjennylist

Sat, 24 Feb 2018 12:00:00 +0000

Inspired by some impressive work on textile flip-bit displays, and with creative steampunk outfits to create for Christmas, [Richard Sewell] had the idea for a flippable magnetic eye in the manner of a flip-dot display. These devices are bistable mechanical displays in which a magnet is suspended above a coil of wire, and “flipped” in orientation under the influence of a magnetic field from the coil.

In [Richard]’s case the eyeball was provided by a magnetic bead with a suitable paint job, and the coil was a hand-wound affair with some extremely neat lacing to keep it all in place. …read more
