    Easy Life-Saving Water Filter

    very misleading and potentially very dangerous..this is a physical filter ONLY and will NOT remove harmful biological/chemical pollutants which may be fatal IS THIS CLEAR NOW?

    2-Year Ultra Low-Power LED Flasher

    EPE magazine had a series of micropower circuits developed by rev Thomas Scarborough (South Africa!) which would run off solar/supercapacitor power supplies; they used CMOS logic ICs (Phillips ones worked best; some others failed to even operate at such low voltage levels) and super bright high-efficiency LEDs.The beauty of 'going retro' is you are not drawing power to run ANY processor core; which drops power consumption to next to nothing! and the chips are widely available and fairly cheap.The long-obsolete LM3909 was developed for Fire Escape signs,which could work if mains power was lost; it used the principle of dumping a capcitors charge into the LED to get high brightness with low average consumption.This could easily be done the 'modern' way with a microcontroller and a SMD FET...

    Electric Wheelchair Controller

    Really well done; SUCH a worthwhile project. i have repaired several electric wheelchairs; in europe these things are eye-wateringly expensive, American-branded (but usually made in china...) i wasn't at all impressed with their control circuits.yours is modular and serviceable..tuck it all away in an IP-55 rated electrical box to keep the weather out;and it will probably outlive the motors!

  • Ultrasonic Rainwater Tank Capacity Meter

    Nice One! i can see me trying this one out; i was planning this as a project for a water management system of linked cubes.although i dont actually like Arduino's IDE, the hardware cost less than i payed from the bare chips from Mouser; IF you are willing to wait for it..! (though post from Mouser's warehouse in Texas took 1 1/2 days to get to the Paris postal hub...then another three days to go 3 hours down the road...80/ )Water butts can be a pain in the butt.at a freinds house in Normandy its either boom or bust; the 1M square cubes there are either overflowing enough to re-enact the battle of the Somme,or just a layer of green slop lurking at the bottom...all from just half a of a shelter's tin roof...(the mule doesnt like the rain!) like you say;when it rains it RAINS!It's a wierd ...

    Build Your Own Storage Shed!

    an easier way to do the door is to screw on the inside bracing THEN cut the 'door' panel out of the 'wall' panel. you can even attatch the hinges first;if you carefully cut the panel around them ( to avoid hitting the metal with your saw).using this method means the door HAS to fit the hole;as theres no way that it can't! 80)

  • Drilling Metal With a Drill Press

    Drilling a smaller 'pilot' hole will give better accuracy for all but the smallest drills;and is very important when using larger size drills,it helps guide the drill in a straight line instead chattering about until it has something to 'bite' into. If your drill bit produces trianglar holes re-clamp it in the chuck a fraction of a turn round;sometimes the stamped size marking causes it to sit unequally in the chuck,so can swarf, grit, or burrs caused by the drill getting 'spun' previously in a chuck.Keep the chuck clean with thin oil. (which should ALWAYS be used to lubricate the spot the drill lands on BEFORE drilling,and more part way through if it burns off! high-speed steel 'HSS' drills can cope with heat,upto a certain level ! but oil gives them an easier life; by reducing abrasio...

    Drill Press Table

    nice build,i like the toggle clamp idea for attatching it to the drill; much easier than messing about with g-clamps like i have been doing! but leaving off-cuts on the running saw is a NO NO... if they vibrate into the saw blade they get shot like bullets,in your direction! (as i found out!) ; o)

  • How to Make DIY Soft Jaws in 60 Seconds!

    its better to make these with the folded ends horizontal (folded round the ends of the jaws);that way they hold themselves in place as the jaws are opened;you can also rivet (or glue!) soft plastic or wooden jaws onto the metal 'slippers',so they dont mark soft materials,such as plastic.

  • Give a New Life to an Old Motorcycle! How to Build a Cafe Racer

    so.you unbuilt a perfectly good touring bike,to make a streetfighter...hmm.i have the sports version of this one one in the garage,decaying;complete with leaking fuel tank (common on these,despite the fuel tanks being made of aluminum) and burst radiator.never thought they looked right without the 'tupperware' hiding that UUUglY motor! but hey; at least yours GOES!a couple of points...the lack of a front mudguard would fail its road worthyness test in the UK, and most of Europe too( you can get away with anything in France !).you will also notice that even the slightest bit of rain sprays straight into your face,knees,boots...Removing the fairing loses a good deal of weight...BUT the upper front piece has a mesh grille to stop stones puncturing the radiator...and is shaped to funnel air...

Streetfighters/Cafe racers are a good way of resurrecting scruffy-looking bikes with bodywork 'issues' (the sort of repairs that cost serious money to fix) and adding your personality to a boring old factory-standard model...without the shame of riding an old dog of a bike! or turn to the dark side and deliberately make a 'Rat Bike' ;0)
