Okay, now we think [James] is just on a mission to see what he can build using the dollar store as his parts bin. This is the nearly finished replica of the cyborg skeleton from the Terminator franchise. It’s made mostly from things that cost $0.99.
Actually we’ve got that a bit wrong. [James] is really shopping at the £0.99 store but the concept is basically the same. He’s already shown us that he’s a pro at this with the arc reactor replica we recently saw from him. This time around a set of speakers donate their enclosures to build up the spinal column supporting the skull. Fittingly these are glued together using a hot glue gun from the store. The sides of the skull are carefully crafted from a set of four plastic bowls. The jaw comes together thanks to the corners of a plastic box’s lid. And finally the majority of the face is from a golden skull costume mask. Spray it all grey and pop in some LEDs for the eyes and he’s done it! He show’s off his final creation in the video after the break.

Some people have a real knack for sourcing parts at the dollar store. [James] is one of those people, having built this Arc Reactor replica using mostly dollar store goods.
The light source is an LED disk light that was removed from its enclosure. A sink strainer, the plastic holder from a package of sewing pins, and some wire mesh go together to make the first layer of the bezel. The push-pin holder is what has the ring of narrow rectangles around the bright center. It was painted black and attached to the sink strainer which provides the concentric holes in the center of the device.
For the detail around the outside [James] went with some clear-plastic drinking cups. By cutting off the top centimeter of each and stacking three together he gets the clear base he was after. The rest of the parts were gathered from his electronics supplies. DIP sockets straddle the drinking glass rims, and are wound with copper wire for the look seen here.
We put this near the top of the dollar store builds along with this Blade Runner umbrella.
One of the bulbs in the dome light of [Pete's] car burnt out. These were a bit hard to get at for replacement so he thought he’d try something that would last longer, and have no problem standing up to the vibrations that go along with automotive electronics. But plug-in LED replacements cost more money than he was willing to spend. Luckily there was a dollar store next door to the auto part shop, so he bought three LED touch lights for the dome and cargo bulbs.
After cracking them open he found that the LEDs were wired in parallel. He needed to put these in series in order to take advantage of the voltage drop. After de-soldering the bulbs he measured the characteristics of one, then calculated the voltage drop and resistor value using a worst case scenario of 14V to avoid damage to the light when the engine is revving high. From there he cut the traces on the board and rewired them. The reworked module fits nicely and as you can see in the image, gives a more pleasing light color than the orange of the stock bulb.
[Vik Oliver] came up with a webcam focus fix that is so quick and simple we never would have thought of it. He received the webcam as a gift and mounted on an articulated lamp so that it could easily be positioned around his projects. The problem is the camera lacks a focus adjustment so the close-up shots were blurry.
In what we consider a eureka moment, he sourced a pair of dollar store reading glasses to fix the optics. The glasses came with their own mounting bracket. He clipped them in half and wrapped the wire ear support around the camera body. Great hacks don’t have to be complicated, and we need to do a better job of looking at the dollar store for project parts!
Here’s a quick and easy illuminated umbrella that [Mikeasaurus] built. How’s this for economical? He found an umbrella that someone left on the bus, and used an LED flashlight and clear poncho from the dollar store for the rest of the parts.
The scavenged LED circuit board is the perfect diameter to fit inside the handle of his umbrella. He removed the middle LED and drilled a hole in the board for the shaft to pass through. Although not well detailed, we gather he managed to shoehorn two CR2032 3v batteries underneath the PCB to power the device. The poncho is wrapped around the shaft to diffuse the light. This is a clever solution as the flexible plastic still allows the telescoping shaft to collapse down to its most compact size.
[Mikasaurus'] umbrella doesn’t make noise or emulate the weather but it is a clever idea. The low difficulty level and availability of parts makes this a great project to do with the young ones who don’t get included in your more intricate hacks.
