Making and use of a soil+urine battery. Berto A 2022-12-11 | With the advent of ultra-low power electronics, the use of soil, urine or manure batteries is interesting again. Also ULP modules with applications for the Internet of Things can be powered by this kind of organic batteries.The question what can I do with it, I will answer with powering two kinetic ULP devices. A soilurine battery duration test is still going on.
Hoe maak en gebruik je een aarde-urine batterij? Berto A 2022-12-06 | Je loopt dagelijks over de grond/aarde maar... dat er stroom uit te halen valt is voor veel mensen onbekend. In deze video laat ik zien hoe je een aarde batterij maakt en toon ik ook een eigen toepassing. Met een koper en zink elektrode in vochtige potgrond maak je een batterij. Een beetje urine erbij en het vermogen verdrievoudigd. De potgrond absorbeert de eventuele reuk, dus dat hoeft geen probleem te zijn. Door de cellen in serie aan te sluiten kan je de gelijkspanning verhogen. In deze video zijn dat er vier, goed voor 3Volt. Dat is genoeg voor mijn toepassing.
Aardbatterij voedt magneet pendel Berto A 2022-11-17 | Kan je met stroom uit tuinaarde een pendel of motortje voeden? Ja dat kan met materiaal uit de bouwmarkt. Als anode is een koperen buis en als kathode een verzinkte plaat gebruikt. Alleen uiterst zuinige (microWatts) machientjes kunnen op deze energie langdurig lopen. De tuinaarde moet niet te nat zijn, licht vochtig is OK. De pendel in de video gebruikt 20 uAmp bij 3 Volt. Het schema van de schakeling is in andere video's te vinden.
Earth battery powers pendulum Berto A 2022-11-16 | Can I use an earth battery to run ultra-low-power devices? I made a simple battery with soil, coppertube and a zincplate. The cell voltage is 0.9V and a short circuit makes 200 microAmp. The pendulum consumes about 20 microAmp. A supercap of 10F is buffering battery. Duration tests have still to be done. Also soilcell improvement is part of the project.The Non-Stop Solar Devices are running for month's and some for years.
Covid-19 hometest motor Berto A 2022-04-11 | What can you do with all used Covid-19 hometests? My proposal is to turn it into a pulse motor on solar energy. In this way you make it into a memory object with a very long runtime.This pulse motor has a simple construction. The rotor runs with magnet bearings build in the plastic Covid test strips. Below a small glassplate I glued a magnet. This keeps the rotor shaft in place. The shaft does not touch the upper bearing. As actuator I use the Hall sensor. That is also the driver for the coil. A LED shows the pulse and can be used for the adjustment. That's a pretty accurate job. I glued the sensor to the coil and moved it until I reached the optimal result. All the test strips I glued together with second glue. The solar energy is stored in a super-capacitor and can supply power to the circuit for at least a week. This without any power supply from the solar panel.
Zomerfeest in het ViegenPark 2021 Berto A 2021-07-31 | Het was weer een uitbundig gebeuren, het zomerfeest, midden in het Viegenpark. Bewoners uit de omringende vijf wijken van Maastricht Noordwest namen deel met een brede glimlach. De karavaan van Samen Groener, Trajekt en Vrijwilligers die hier neerstreek, maakte het park tot ons park.
Stichting Samen Groener; voor meer levendigheid in de wijken. Berto A 2020-11-16 | Alle initiatieven in de bovenstaande video leren dat het Viegenpark een impuls kan geven om het buurtleven groener, socialer en creatiever te maken. De Werkgroep 'Sociaal Groen' is verzelfstandigd in de 'Stichting Samen Groener Maastricht Noord West'. Haar doel is: Het vergroten van de beleving van natuur, de aandacht voor de natuur, het versterken van het sociale weefsel en de kwaliteit van het leven in Maastricht Noord- West. Dit door het bevorderen van Sociaal Groene verbindingen in Noord West Maastricht en tussen andere wijken in Maastricht. Dit doel wordt bereikt door een reeks samenhangende Sociaal Groene activiteiten in Maastricht Noord West. 'Universiteit met de Buurt' staat dit initiatief met raad en daad bij. Het is een platform voor samenwerking tussen universiteit en bewoners, om wederzijds van elkaar te leren en om te experimenteren met nieuwe manieren om de veerkracht te vergroten.
How to make the Magic Mouse Wireless Charging Berto A 2020-06-22 | If Magic Mouse3 comes to the market, it has a certainly a wireless charger on board. This is a makers version. Without any non-reversible steps I went from a Magic Mouse 2011 to version 2020. In this part 2 we see a way to modify the Magic Mouse to charge wirelessy the Li-ion battery. Two parts are important; the Li-ion AA battery (with build-in charger and over- and under protection circuit) and the wireless charge modules with the coils and mini boards.
Rechargeable Magic Mouse with NiteCore NL1475R Berto A 2020-06-18 | Features:- Modification within the battery compartment, no change of the internal circuit. - The conversion time is, depending on tools and skills, about one hour.- Material cost are $10 for a Li-ion 750mA rechargeable NiteCore NL1475R battery.- Most important, the modification is safe and does not damage the mouse.- I found no difference in performance after the modification.- The only downside is that the battery level is incorrectly indicated on the computerscreen.- The Li-ion battery replaces, with more than 500 charge- discharge cycles, about 500 disposable batteries, which is cost effective and environmentally friendly.
Two Pendulums interacting randomly Berto A 2020-05-16 | The aim of this project is to cause a continuous swing of 2 pendulums. I discovered a nice interplay between an active and a passive pendulum. It is an interaction of permanent-magnetic and electro-magnetic force fields combined with gravity. Last year I started to find out how to make constantly moving objects on solar energy. Simple- and stable design is the way to go. The use of supercap energy storage require's very low power consumption. Day and night, summer and winter, cloudy sky and in-house light conditions. This duo-pendulum runs for a very long time, maybe longer than my lifespan.
Continuously rotating sphere in a glass jar Berto A 2020-04-14 | The best place for an always spinning sphere driven by solar energy, is in a glass jar. A moving thing is an ideal toy for cats or other pets and a jar gives some protection. The electronic driver circuit and the mechanics consists of just a few components. The styrofoam ball with a sharp needle as axis, rotates under a magnet bearing. The needle rests against a small glass plate. Four magnets on top of the ball, a solarpanel, a supercapacitor, a coil and a sensor are all the essential parts to keep the sphere spinning for a very long time.
Parasite Pulser Berto A 2020-03-29 | The DIY Parasite Pulser looks simple but it has some nice features build-in like a 8 minutes timer and a sweep pulse generator. The frequency range (10 to 200Khz) is very wide compared to conventional products. The potmeter determines the central frequency. This pulser, also called the hulda clark zapper, is often used in alternative medicine. Its primary purpose is to boost the immune system by killing bacteria, viruses, mold, fungi, etc.This works by applying a very small current of a specific waveform and frequency to the hands by electrodes. For more information: rifeandzappers2.com/coronavirus-frequenciesCentral frequency is 33.4 and 72.5Khz. That is Pulser potmeter scale 3 or 7.Claims and counter claims of its effectiveness are all for what it is worth.
Continuously spinning Ball Berto A 2020-02-27 | My goal is to make a continuously spinning electric pulsemotor on solar power with Supercap storage. So, also by darkness, cloudy sky, winter and in-home light conditions; it keeps on going. The circuit is using far less than 100 micro ampére. Magnetic bearings are reducing the friction to a minimal. Experiments in this very low power field requires specific skills in mechanics, electronics and measurements. - My starting point:Solar panel 5.5V and a Supercap of 50F 3V maximumThe challenge is to keep the objects small, windowsill size.Forever, eternal and always means at least a year testrun. Simple design has the most chance to resist wear or stop.This project has no perpetuum mobile nor free energy claim.- Meeting friendsComing in my room with this ‘fragile moving entities’ is meeting friends. It is my way to come into contact with the everlasting power of the sun and the electro-magnetic, magnetic and gravity forcefields.
Double Spin Pendulum Berto A 2020-02-22 | This is a pulsed pendulum of a special kind. The magnetic weight hangs on a sharp needle. It can move near frictionless around with the magnet poles in horizontal direction. The pendulum spins around the coil and around it's own axis. A 3V solar panel feeds the 10 Farad, 3V supercapacitor. A simple 2 transistor circuit is firing the coil as a magnet passes by. This pulse then repels the magnet. The very low power circuit uses only 15 uA on average.
Ultra Low Power Pulse Motor and Pendulum Berto A 2019-04-30 | Why not building a machine that can almost run without extra energy? The ultra low current research is for people interested in ultra efficiënt electronic and mechanical devices. In my case pulse motors and pendulums. This video shows an on-going investigation to make this devices forever running on solar power.
Donut Motor; a very low current pulse motor. Berto A 2017-12-13 | The Donut Motor is powered by a 3V and 235 mAh Lihium cell with a current of 13 uA. This gives a motor runtime of 2 year. It is a DIY projectvideo with all the information to copy. It is an ongoing project to enhance the efficiency to the max. When you subscribe, you can follow this quest.
DIY Digital Gauss Meter Berto A 2016-02-05 | Looking for a Gaussmeter in a shop, I saw prices of more than hunderd Euro. There are just a few DIY magnetic field meter circuits on internet but of poor build. So, I designed one on my own. The circuit is simple to replicate with a Linear Ratiometric Hall Effect Sensor, the SS495A from Honeywell (2.50Euro). For the display I choose a mini digital panel voltmeter(2.50Euro). The window comperator is made with a LM339 IC. There is only one trimpot for the offset between the North (Red LED) and South (Green LED).The Hall sensor I made on top of an aluminium tube; this probe can be separated from the box for tests at difficult places. A voltage read out on the display can easily be converted to the Gauss or Tesla units for magnetic induction or flux.More info: www.laboratoiredesynthese.comMuch more info: http://www.instructables.com/id/Digital-Gauss-Meter
Linear Electromagnetic Resonator 7 Berto A 2016-01-25 | Last time we saw that the total use of the resonator was about 15 mA by a voltage of 5Volt. Motor and the generator circuits are now on separated breadboards. The use of super capacitors improve the puls power in the motor coil. This you can see and hear when I switch the caps on.With bon courage I started making a stack of seven spools; the effort was worth it. The new linear generator coil stack looks fine. I was very curious what the output power of the coil stack was doing. The first testst were disappointing All coils in series arouse lesser power than the single coils. I have to change windings and magnets; with hope for better results.More info: http://www.laboratoiredesynthese.com
Linear Electromagnetic Resonator 6 Berto A 2016-01-18 | This video shows the making and use of magnets in repulsion mode. Two magnets are glue'd together and are showing a special behavior at a 20 Hz resonance of the resonator. I was surprised by a perfect triangel waveform and a decrease of the supply current.More info: http://www.laboratoiredesynthese.com
Linear Electromagnetic Resonator 5 Berto A 2016-01-14 | There have been many changes made to the resonator. Experiment shows that the vertical position of the resonator is the best. That's to say; less friction, stable resonance, use of the gravity and the least energy usage. The 2 magnets are bouncing inside the tube with the help of gravity and the bump magnets. This 2 magnets at both sides of the tube I placed in the hackneyed pen cap for a quick change of the magnets within the tube. The resonator has now three bifilar wound coils: - An activator solenoid with a 0.2 mm AWG32 and a 0.16 AWG34, 50 and 130ohm.- Two pick-up coils with 0.12mm AWG36, 2x 320ohm per coil.I did connect the bifilar windings in series, to get the maximum energy transfer. After the attachment at the tube and the connection with the circuits, the test could start.What is the best arrangement of the magnets within the tube for the best energy transfer? What frequency and pulswidth gives a strong resonance? How to decrease the input current? How to increase the output voltage of the pickup coils? This are the results of the first test:Input voltage: 6VInput current: ~22mA (for the whole circuit!)Output voltage, no load: AC 6V peak per coilOutput current, shortcut: 2 mA per coilThese results are not bad when you take in account the low frequency of the resonator (4Hz).More info: http://www.laboratoiredesynthese.com
Linear Electromagnetic Resonator 4 Berto A 2016-01-07 | This test setup explores the behavior of one or more magnets in a pulsed solenoid. The magnet can move free in a tube. At both ends are small bump magnets. The permanent magnets are all placed in repel position. The oscillator can change DC pulses in width and frequency. Both parameters can change the mechanical resonance of the magnet in the solenoid. With 2 magnets a peculiar interactive magnet behavior can be observed.More info: http://www.laboratoiredesynthese.com
Linear Electromagnetic Resonator 3 Berto A 2015-12-23 | Part 3 shows the progress made to reduce the current in the motor solonoid. The electronic circuit has no longer a relay but a MOSFET to switch the coil. A pulse delay circuit is build around a cd4093 IC. Although it is hard to measure the average current of a pulse wave, I suppose my analog meter can do this well. The input current is now around 35 mA, a reduction of more than 50 percent.More info: http://www.laboratoiredesynthese.com
Linear Electromagnetic Resonator 2 Berto A 2015-12-18 | Part 2 is an explanation how the electromechanical resonator works. How this 'motor' can be made more efficient by decreasing the activation time of the solenoid. I lifted the permanent motor magnet by 2 supporting wheels what will decrease the friction. At the end I show measurements at the motor solenoid and on a generator coil. More info: http://www.laboratoiredesynthese.com
Linear Electromagnetic Resonator 1 Berto A 2015-12-18 | Free Energy for Geeks is the exploration of a linear electromagnetic resonator; on a simple and easy to build electromechanical test set.

Kupferspulen Wickelmaschine aus einer Angelrolle Berto A 2015-12-03 | Diese Kupferspulenwickelmaschine, für kleine Spulen, kann leicht von einer Angelrolle konstruiert werden. Eine Umdrehung der Haspel Griff macht vier Windungen der Spule. Nehme der Bügel, die Schnurrolle und die Fadenspule von der Angelrolle auseinander. Aus einem Aluminiumband machen Sie eine U-Form Bügel, um an den Wickler mit zwei Schrauben zu befestigen. In der Mitte ist ein Loch für das zentrale Auf- / Ab-Spindel. Der Bremsanpassung wird der neue Spulenhalter. Die Drahtführung macht gleichmäßig verteilte Wicklungen auf der Spule. Am oberen Ende der Drahtführung ist ein Stück Leiterplatte mit Löchern für Wicklungsdrähte parallel an der Spule zu führen. Das Video spricht für sich.
DIY Coil Winder from a fishing reel Berto A 2015-11-25 | This simple copper wire winder is perfect for small coils. With a minimum effort you can make customized coils. The only material you need are some strips aluminium. The wire guide makes evenly distributed windings in the spool. http://www.laboratoiredesynthese.com
Hammock build within clothes Berto A 2015-08-01 | This diy project investigates the multi-functionality of clothes. In this case a built-in hanging chair. This is a proof of concept rather than a fashion design project. The WeDangle can change the way we sit drastically; it is a customized comfy seat that we carry always with us. You can use it as a swing seat, as an armchair and as 'une chaise longue'. The only thing you need is an attachment ring above your head. I take always a tension belt along, with that I can adjust the height of the attachment point. That is also the only limitation. You can use the WeDangle, just as a hammock, on trees, with a ceiling connection or at a frame. This invention can make standing chairs and benches obsolete. They need more space, maintenance and material. The WeDangle is a seat that suits your posture/comfort at home, at work and outdoors. Most important is the children's fun to swing and to turn around with the feet from the ground, just easy dangling. More info: http://www.instructables.com/id/WeDangle-A-seat-within-your-clothes
Landhuis Reopening Berto A 2015-03-15 | Saturday 14 march 2015, the start of the new season with a reopening of the livingroom and kitchen. We enjoyed workshops, cooking, music, chatting, fireplaces, cake, tea and.....pizza.
Pallet Coffee Maker Berto A 2015-03-06 | This is a project of creative reuse, upcycling or repurposing. Breaking down my coffee pad machine, and separate the housing from it's essential parts, is a revelation. My first impression; so much plastic housing and just a few parts machine. Why not showing the machine in it's real shape in this pallet age? A reused pallet is an icon of a movement that points to an anti consumerism lifestyle and sustainable living. Thousands of pallet projects worldwide indicate upcycling, creativity and a personal production of consumer goods.I show a coffeemaker inside out, on a mini pallet. A form of 'guerrilla machine redesign'. Living in a world of black boxes, it's a provocation to show the "internal parts". Also an insight in the machine processes gives us more understanding if something goes wrong. 'When you don't open it you don't own it'. How many broken coffee makers have never been opened for a short inspection inside the housing? I am surprised, as repairer, how fast the problem is found after opening a 'secret box'.

Het Bellevue Wandelpad Berto A 2014-04-23 | Het zou mooi zijn als het Bellevue pad er kan komen, langs de noord- westelijke hellingrand van het Maasdal. Die rand begint bij de Hoge Fronten gaat voorbij Fort Willem steekt boven aan de Cabergerweg over naar het Rondeel en gaat verder richting Belvedere berg. Het is een groene zone waar weinig mensen komen omdat het ontoegankelijk is. Met behulp van luchtfoto's (10 jaar oud!) en video heb ik geprobeerd een voorstelling te maken van het gebied. Een eventuele uitkijktoren geeft een prachtig uitzicht over stad en Maasdal. Vooral de mogelijkheid om een rustige natuurwandeling in dit deel van de stad te kunnen maken zette mij aan tot dit plan.

Wood drill bits made of a spoke Berto A 2014-03-03 | Drilling wood, specially if you have to do it by hand, must be done in steps: first a small hole, then a bit larger, then to size. Or as many in-between steps as needed. Woodworkers have collections of drills, but what to do when you have to start from scratch? We start with a drill bit of good quality steel, that is within reach for many people: a bicycle spoke!A step by step Instructable shows you how to make with your bare hands from a bicycle spoke a multi bit wood drill. See: http://www.instructables.com/id/Wood-drill-bits-made-of-a-spoke
RattleGen LED Flashlight Berto A 2014-01-05 | Nearly 200 years ago Michael Faraday has discovered electro- magnetic induction. A changing magnetic field produces an electric field in a coil. Today, I found a simple way to gain electricity with a relay and a strong magnet. I call this kinetic generator the RattleGen because by quickly pressing the lever of the relay (the only moving part!) it makes a rattling noise. This electro generator is nearly solid state and produces enough energy to power a LED. Compared to 100 years of dyna flashlights, as we know them, my RattleGen torch is nearly indestructible because of the few parts. The electronic circuit is very elementary; 1 relay, 4 diode's, 1 resistor, 1 electrolytic capacitor of 1000 microfarad 16 Volt and one superbright LED.
