Afin de motoriser un véhicule télécommandé je vais utiliser des servos modifiés pour autoriser une rotation continue. Normalement les servos classiques sont prévus pour des rotation de 120 ou 180° mais pas 360.

Cela est du à la présence d’un potentiomètre pour l’asservissement du moteur et d’une butée sur les engrenages. En retirant ces deux éléments, on peut autoriser la rotation continue du servo. On démonte l’arrière du servo en retirant les 4 vis. Le potentiomètre est dessoudé de la carte du servo. Le potentiomètre est remplacé par 2 résistances de 2.2K permettant de bloquer le point « milieu du servo » Pour la partie mécanique, il faut retirer la butée d’un coup de dremel. Encore 3 à modifier… Des roues de voiture radiocommandée 1/10 vont être montées sur les servos. Ressortons openscad. Et hop des adaptateurs ! L’objet est disponible sur thingiverse La suite bientôt avec la modification d’un routeur TP-LINK MR3020 pour piloter le robot.

Polar Coaster Version 2 at Buildlog.Net Blog. December 21st, 2018 by bdring I recently decided to update the Polar Coaster project. The primary reason was to update the controller to use Grbl_ESP32 firmware. I also thought I could make it smaller, lighter and remove a little cost. Controller The old controller was not custom made and just sort of tacked onto the back. This increased the size and didn’t look very good.

Firmware The controller runs Grbl_ESP32. WebUI The controller has a web server that serves a web app. SD Card This is a great feature. Stepper motors Both versions use NEMA 14 motors. Gear Driven Rotational Axis I decided to change from a belt driven rational axis to a gear driven one. Rotational Platter The platter rotates around a central bearing. Buttons Since there was a little room left on he board, I added three buttons. Battery Power I made a battery case in the base of the machine to hold an RC style LiPo battery. Future Put kinematics into the firmware. currently files need to be pre-processed with the python script.

DIY GPS for Nikon D7000. Hello All, With this unit plugged in, all pictures will be geo-tagged automatically secondly, camera clock will automatically be synced. Though there are GPS unit available in market for camera but for me it was fun to put it all together and do it as DIY project. Here is how you can build your own unit. Tech details before we proceed Nikon D7000 → GPS input should be plugged into shutter release cable. Adafruit GPS breakout board → Works with 3.5V/5V input. MC-DC2 to USB Mini pin cable → Use multimeter to to figure out which MC-DC2 pin leads to USB pin. USB Mini B breakout boardVCC → this draws power from cameraD - → shutterD + → GPS Data in @ 4800 baud rateID → Focus "ID" pin is "D-" pin is for Shutter release Once USB breakout board is connected to camera, it starts drawing power. If you are planning to use camera with shutter release cable, you will have to extend this circuit to have addition connections/controls for cable release.

Circuit Arduino Code for ref. #include Finished Product. Seven Pro Tips for ESP8266. This part is taken from the blog by Erik H. Bakke. Thanks to Mr. Bakke for is valuable work. From the power consumption chart below, we see that the WiFi radio switches on as soon as the ESP wakes up. The bootloader runs for about 0.35 seconds, after which it hands over control to the code uploaded to the ESP.

After that, the next 2.3 seconds are spent connecting to the WiFi access point. This is just establishing an association with the AP, there’s no DHCP or other traffic yet. Next comes 1.2 seconds of nothing at all happening. Next is DHCP traffic. From the graph, we can see that each time the device wakes up, we spend about 1.5 seconds doing useful work (reading sensors 1.2 seconds, transmitting results 0.3 seconds), out of a total 8.3 seconds the device was awake.

Now, let's see how we can reduce the consumption. Disabling WiFi when waking up As the WiFi radio is on when the ESP wakes up, we wake up with 70 mA current even if we’re not using the WiFi yet. Using WAKE_RF_DISABLED. Arduino USB Number Pad Project « Mr Jones Education. This has been an experimental Arduino project – it’s to prove a concept idea for a giant number pad floor pedal for use in a classroom environment. I thought if I can design and make such a device it would greatly increase motivation for learning times tables etc. where children can key in the answers by hopping from digit to digit or by hitting the keys with a sponge mallet – should be fun! These notes can also serve as a classroom project that integrates science (electronics), computing (programming) and DT (switch design). All the materials here are low cost. Better still, the same Arduino board and jumper wires can be attached to each independently designed and built number pad in turn – so very manageable as a classroom technology project.

Needed for this is: an Arduino Leonardo – because of its built in USB capabilities some jumper cables (x7) some crocodile clips (x7) a USB type A to miniB cable some card, foil and double-sided tape Step 1 Designing and building the board… Step 2. Encyclopedia of ATX to Bench Power Supply Conversion. This guide has almost every ATX computer power supply to bench power supply published to date on Instructables ( as of Dec 2014, about 70 unique instructables). It should be interesting to both those who want to do a conversion, and to those interested in the evolution of a popular topic that has been done over and over on the site.

Sometimes the new projects had something to add sometimes not so much. Some of these projects are great, some original and some just so so. I have sorted more or less by year. The first instructable listed, is I think the first one, by date, on the site. ( but this may have been messed up byupdates that are now added at the top ) I have added a brief comment on each one. I do not normally view videos so the only comment on them is “Video”. Salvaging Liquid Crystal Displays (LCDs) - All. 10 Breadboard Projects For Beginners. Before you start making the projects, you should understand the functioning of every project to know what are you really doing. For this you need to know about important electronics components used in a circuit. So here is a brief description of all the electronic components used in the projects.

I have left the ones that are not used in the projects and are too complicated to understand. Check out randofo's Basic Electronics guide that teaches you almost everything about basic electronics. (1) Resistor: A resistor is a device that reduces current in a circuit by offering obstruction to the flow of electrical current. . (2) Capacitor: A capacitor is a device that stores electricity inside it when it is supplied and gives it out in a circuit when there is a loss in electricity.

. (3) Transistor: A transistor is a device that amplifies a small current applied on its base pin to produce a large current that flows between the collector and emitter pins. . (4) Integrated Circuit (IC): (5) Diode: UobboU Photo Arduino. Un graveur laser à commande numérique à base de Raspberry Pi. J’ai contacté Daniel pour obtenir son accord afin de traduire son article.

Il m’a répondu très rapidement que cela ne posait aucun problème : « Hi François, Sure! I definitely love to see the project translated to French and have more people get interested in it. Please go ahead and translate it, and fell free to let me know if you have any question. Comme il est intéressé par cette traduction, je vous propose de découvrir son projet qui est vraiment très intéressant. N’hésitez pas à vous rendre sur cette page qui donne tous les détails de la construction. J’ai récemment construit un mini graveur laser CNC (computer numerical control = à commande numérique) à l’aide de deux graveurs de DVD de récupération et moins de 10€ de pièces supplémentaires achetées sur eBay. Il y a eu beaucoup d’exemples de personnes utilisant un Arduino pour de la commande numérique. J’ai choisi une approche différente en utilisant un Raspberry Pi. Soit une batterie déchargée immédiatement. Raspberry Pi GPIO home automation. DIY SMD metal stencils – the definitive tutorial | LowPowerLab.

In previous posts (here and here) I described my efforts and research to develop a DIY method to make good quality SMD metal stencils at home. I have since experimented some more and I believe I found the best method (so far) to do this with very cheap materials, yielding very good results. Since transferring the toner to the soda can aluminum alloy was the most challenging part, I kept experimenting with different transfer mediums and other ways of possibly facilitating and perfecting the transfer.

Finally the solution is here: consistent, repeatable, “perfect” toner transfer, every time. Step 0 – Be safeBe safe and wear a respirator mask, goggles, gloves and use ventilation! Step 1 – Prepare soda can aluminum Cut and unbend the aluminum on a flat surfaceHeat the aluminum with your iron for a minute. For toner transfer I tried many things and initially I recommended transparency film. Step 3 – Transfer the tonerI then use a stack of sticky notes to transfer the toner. Costs Conclusion.

Idée d'insoleuse. L'objectif de cette page est d'inciter tout novice en électronique, qu'il peut réaliser une insoleuse légère (j'insiste), de qualité et pour un prix très abordable. Celle présentée est prévue pour faire du double face, mais qui peut le plus, peut le moins! Matériels nécessaires: 8 tubes actiniques (U.V) spécial circuit imprimé 15W (4 par faces). 1 mallette plastique de largeur au moins égal à 50cm, de profondeur ~35cm et d'épaisseur ~12cm. Vu chez Radiospares (pub gratuite) Du miroir adhésif (on en trouve dans des camions itinérants).

Etapes de réalisation: 1 Mise en place du miroir adhésif + réglettes alu pour le maintenir (à moins que vous n'ayez un adhésif de meilleur qualité que le mien... qui adhère mal sur le fond de la mallette). 2 Mise en place des colliers "CLIPX" avec visserie de diamètre 4mm (il va falloir couper les vis pour ne pas dépasser et empêcher les tubes d'être clipser). En pratique: la récupération de l'électronique des ampoules économiques 4 Câblage final. /book: Bootcamp : "Make ta machine"
