    Portable Camping and Surfing Shower

    After adding the larger radius feed hose and spray nozzle, remove the internal small radius pickup tube entirely and enlarge the feed hole to match the new delivery hose. Fill the container with your temperature adjusted water, pump up the pressure and when ready to shower turn the whole thing upside down. You will need to provide some other alternative mounting to hold it in this position.

    Bench Power Supply

    I admire your video production, your design skills and application, but it is still just a build a box project. I am more interested in what goes in the box and found this a little sparce and digressing considerably from the main title which initially got my interest.

    Bench Power Supply

    So you made a box and put things in it. The power supply seems to be irrelevant. Nice video though.

    Secret Bottom - Wood Box!

    To make it really secret, forget the tray inset and make a false floor that drops in and fits precisely. Construct a divider that fits in slots in on each inner box side, secured divider by false nails to fix it. These nails can be carefully levered out and would allow the divider to be removed. Invert the box and the false floor falls out and exposes the hidden compartment.

    Mega Power Bank

    Made similar power pack some years ago as a portable power source to run a guitar amplifier. Made provisions for recharging on board battery when mains power available and use a motorcycle trickle charger either hard wired or via the 12volt cigarette lighter power plug.Add a power inverter to plug in the mains chord of a guitar amplifier [or other light load mains powered device]. Power inverters often have a regulated USB plug power connection as well for USB powered devicesConnected the power inverter via the 12 volt plug. Guitar amp would run several hours in this configuration.Final mod is to have a suitable chord to recharge charge internal battery from car 12v socket to Power Pack socket.Better, if you are really clever, you can plug the power inverter in to your car socket, plu...

  • How to Clean the Inside of a Headlight

    Sew a long and strong thread to your inside cleaning pad so that all you need to extract it is remove the outside magnet and then pull on the thread. Great project!

    Custom Tool Wall

    Excellent project. I hope you can guarantee security.I once had a well set up and displayed tool collection like yours. An enterprising burglar was able to pick the best and most expensive from my tool display. In and out in under six minutes before any response could be be effective from my alarm system. I now have a well organized tool shambles, in cupboards and tool boxes all over the place. At least I know where everything is. The extra time taken sorting out what I want for a project is more than compensated for the time and expense taken in replacing lost tools. Now let an intruder pick out the best of my collection if he can find it in under six minutes.

    Solar Power Bucket

    DO NOT CARRY OUT THIS INSTRUCTABLE PROJECT!!!!!! Do you have an electrical wiring diagram or do you have the wiring done by an approved and certified electrician? For all the safety and health reasons mentioned in many other comments as well as my understanding of the engineering I consider that this is one of the worst and ill conceived projects that I have seen.It would be far safer to connect the various separate components in the open air and just carry them around, unassembled in the bucket. When you need to charge the battery, connect the solar panels and controller. When you need power connect the USB unit or the Power Inverter. Use the bucket as a method to carry all the components for when you need them. Also the buck would still be available for the multitude of other us...

THIS IS A DANGEROUS PROJECT DO NOT MAKE IT!!!!!

    Battery Eliminator

    Why not keep the original transformer plug fitting and have several different dowel fittings to be plugged in for other operations?
