DIY Macro Adapter using Binoculars and a Film Canister

at 5:29 am. Filed under Cool Gadgets, DIY Hacks

 

Dave Peterson sent in this cool Macro Adapter that he built for his Olympus FE-310. It is a wonderful combination of used and disposable parts, you would never guess what it was made from by judging the results alone!

"Took the objective lens out of a pair of MultiTech Survivor DCF 8×22 binoculars, cut out the center of a Fujifilm 35mm canister lid, cut the bottom half off the canister, mounted the lens on the tapered part of the lid (nice fit!) and the canister fits well on the lens barrel of my Olympus FE-310 digital for an amazingly close macro shot."

Hard Drive Tesla Turbine

at 2:25 pm. Filed under Cool Gadgets, DIY Hacks

 

If you have a few old hard drives laying around here is Hard Drive Tesla Turbine that can be made in a few simple steps.

"Build a Tesla turbine from 2 old computer hard disk drives using basic hand tools and a pillar drill. No metal lathe or other expensive fabrication machinery is required and you only need some basic craft skills. It’s crude, but this thing can scream! Tesla Turbines promise up to 92% efficiency of converting air or fluid flow to rotational energy and its use can also be inverted for use as a pump with exceptionally high efficiency too. With compressed air becoming recognised as a feasible form of energy storage, we can see this device in everyday life soon as a source of locomotion."

RC Truck LED Headlight Mod

at 10:38 am. Filed under DIY Hacks, Electronic Hacks

 

CMCKAYVSTMCKAY purchased some super bright white LEDs from us and created one cool RC truck mod. He drilled out holes in the light bar to accept the 5mm White LEDs and also added some in the front of the truck. Have a look at the videos, they show the process that was used to install the LEDs and show how bright they are in the white snow! Nice job! I look forward to see what comes next. If you are an RC vehicle nut you should check out the other cool RC videos that Craig has made.

Homemade Round Object 3D Scanner made from Flatbed Scanner

at 5:31 am. Filed under Cool Gadgets, DIY Hacks

 

This Homemade Round Object 3D Scanner does a good job of scanning cylinders. I like the simplicity of the design that rolls the object over the scanning element.

"I modified a Dell scanner in such a way that it can used to scan cylindrical objects such as a soda can or, in this case, an energy drink can."

Parallax Propeller Laptop

at 5:27 am. Filed under Complex Hacks, Computer Hacks, DIY Hacks, Electronic Hacks

 

Using a DVD player screen, a rewired toy keyboard and toy laptop looks like it made a great start to this DIY Parallax Propeller Laptop.This project demonstrates the power of the Propeller microcontroller. Full documentation is available so that you could make your own.

"This is a Propeller laptop – with a 6502 co-processor and 64K of static RAM! The Propeller handles all I/O for the 6502 and runs an integrated debugger so you can program the computer. The Propeller serves as the programmable chipset for this 6502 laptop. You could use an FPGA in this capacity, but could you easily do this and implement visual debugger software inside an FPGA? Over the years hardware prototyping has evolved from building-block hardware (TTL) to programmable hardware (PLA’s and FPGA’s). I believe the Propeller represents the next revolution: 100% software-based virtual hardware – and I built this laptop to prove it!"

Suzuk-E – Suzuki Electric Bike Gear Casting using CNC and Foam

at 10:36 am. Filed under Complex Hacks, DIY Hacks


Our friends has just finished the next step of the Suzuki Electric Bike build. You may remember the last step which was the making of the gauge package. I found this process very interesting since I have recently purchased a CNC kit which I will be putting together as soon as I have some spare time. In the past I have seen many processes of making parts but I didn’t think you could pour aluminum directly into a mould that has an internal foam part. Have a look at the video below for a great step by step.

“The EPS-foam patterns are packed into flasks with foundry sand and a single pouring spout (or sprue). This is a sacrificial molding procedure, meaning that the foam patterns are consumed in the casting process. So if things go wrong, it all gets repeated, starting with machining new patterns.”
