The APEC RO-90 reverse osmosis filter system has been working wonderfully for the past 2 years. This is a long-overdue pre-filter replacement, but since the sediment in our water is pretty low, the flow is still good enough for general use. The pressure had dropped enough that the storage tank would only hold about 2 gallons instead of 4-5 gallons. The TDS (total dissolved solids) was still very low, so the RO membrane filter is functioning well, so the pressure drop is likel

I love Dyson cordless vacuum cleaners, but hate their poor battery life, especially after about 1-2 years of use, the original battery no longer lasts long enough to finish cleaning. It would be nice if Dyson had made the batteries quick change like cordless drill batteries, but for reasons unknown (probably to make more money and sell you a new vacuum) they chose to hold the batteries in with screws. In this video I show how to use a clip I designed to securely hold the batt

There aren't any other bikes like the ECOTRIC DOLPHIN. It's the lightest, folding, step through, electric, fat bike that I was able to find, and turns out to also be one of the least expensive. The Ecotric Dolphin Ebike w/ Stock Tires WHERE TO BUY ECOTRIC Dolphin Ebike (White) ECOTRIC Dolphin Ebike (Black) The bike will be long term tested by my aunt who wants to be able to ride faster to keep up with her friends in group rides. She also wants to be able to ride the bike on t

If you have an RV fridge that needs a new gasket, but the manufacturer no longer makes spare parts for it, you will need to get it custom made. I have a Dometic Coolmatic RPD-0110U that is 15+ years old, and could not find a replacement gasket for it anywhere. The original gasket has become hard and brittle, and no longer seals well (there are some gaps that a piece of paper will pass through). I contacted Domestic, and they told me that first of all my fridge is a European m

In this video, I show how to assemble and review the COMGROW 3D Printer Enclosure Protective Cover Tent. I specifically bought it to use with the Elegoo Neptune 3 Pro 3D printer, but it should work with just about any printer that is of similar size or smaller, like the very popular Creality Ender 3 3D printer series. The Neptune 3 Pro has a 225 x 225 x 280 mm build volume, which I would say is close to the max build volume for a 3D printer that will comfortably fit within th

The Apple AirTag is great for keeping track of or tracking things. It has a speaker that notifies you of its location by making sounds. Lots of people want to use air tags to help track stolen items like bikes, bags, luggage, etc, but stealth is paramount so the thief can't just find and disable the AirTag. So the speaker needs to be disabled to make it more difficult to find the AirTag. Here's how you can do that without breaking any tabs or needing to use glue to reassemble

This beach shade design is supported by poles inserted into the ground and therefore does not need a sandbag and cord in front to hold it up. Using an 11ft by 9ft beach blanket provides up to 100 square feet of shade. To hold it in the sand, I used 2 beach umbrella lower poles from beach umbrellas that had been thrown away. The poles are 20ft of heavy-duty aluminum tent poles, although fiberglass tent poles could also work. The aluminum poles are stronger and corrosion-resist

When head mounting the GoPro action camera, it's difficult to get the angle correct to properly frame the shots, especially when filming in a narrow mode. Jeremy Cook did a cool hack where he built a laser module to attach to the base of the GoPro camera to help center shots. His video shows how useful it is. I'd rather buy an off the shelf keychain laser pointer and 3D print a simple attachment for it. So I need the smallest keychain laser pointer I can find. Unfortunately,

I combined drifting and glow in the dark gel blasters to create an awesome new sport that’s a lot like real life Mario Kart. I started off with some drift trikes. Then modified the Gel Blaster STARFIRE to be used with an external trigger button. A motorcycle horn switch was attached to the handle bars to trigger it. The tactical rail on the bottom of the gel blaster STARFIRE was used as the attachment point. I used a handle bar mount to attach a picatinny quick release tactic

Now Splatrball has released their own tracer mag called the PYRO Mag, and it works with the SRB1200 as well as the SRB400. At 550 rounds it is a little bit larger than the stock SRB400 magazine (400 rounds) and it is smaller than the stock SRB1200 magazine (1200 rounds). It requires 2 AAA batteries so the power is independent from the blaster, and has an on off switch. I've modded many gel blasters and gel blaster magazines to allow them to illuminate glow-in-the-dark gel bal
