While i was in between houses, i was watching a lot of DIY nanoleaf projects but none of them really stood out.So i want to make a DIY Nanoleaf solution that everyone can afford (by doing it themselves) most important part is i want to make different versions for the different types of people in the world. the ones that can Solder, the ones that cannot, the ones that have the ability to program a ESP device and the ones that cannot. so in short everyone deserves beautiful lighting options in the game room, study or bedroom without the big pricetag but with the satisfaction of building it yourself.I am an starting YouTube creator with an IT background and love to keep my mind in shape by learning new things, i hope in achieving this by looking at products i like and make my DIY version of it.for this projects i have come up with some different pcb’s to make an awesome version of the Nanoleaf Triangle Mini:This part will be placed on three sides of the triangle to connect the LED’s in a closed loop and connect them to the other triangles.i used one in the DIY controller part to.This is the controller pcb i created for the persons that do not want to solder everything together with wires.You put a Wemos D1 Mini on here and flash it with arduino or WLED (i prefer WLED, it comes in a complete package.)if you want to do less soldering and hook all the leds up as one you can use this board, if you order this in white it also reflects the light better.now for the crème de la crème:If you do not want to solder the led’s or connections just use this board, led’s are placed in the corners with the connectors in the middle, the led’s are connected in a circle with an in and out signal. This can be ordered assembled by PCBWay.the 3D printer parts:I made different base parts because of the choices you can maken in pcb’s:the left is for the pcb with everything on board the right is for the connectors where you need to solder the leds on.this is the cover for the version where you solder the leds, the thicker part covers the leds so you do not see the leds but only the diffused light in the middle, the version for the onboard leds has a bigger output in the middle.controller box that you can just like the originals one attach to any side of the triangle.there is a different model for the pcb with everything on it.If you do not have a 3D printer PCBWay can hook you up with amazing printed parts ;)When i have al the parts, i will make a series on how to put them all together just like the other videos i linked below !! to give you an impression on what i made before:DIY Nanoleaf LinesDIY Nanoleaf Lines - Process from start to endDIY Nanoleaf (Hexaleaf)DIY Nanoleaf

we have developed this print for our non-profit organization that makes it possible to talk to a walkie-talkie all over the world we are expanding our services every day and currently we already have members in the Netherlands, Germany, Belgium and want these continue to expand the service on the basis of sponsors.Handyman* aims to connect analog and digital communication in an open domain and to raise radio communication to a higher level using existing and new techniques. This is how we keep this hobby alive and current.Activities take place on a non-profit basis.We do not charge a fee for the use of our website and it is accessible to everyone. We also build svxlink Raspberry repeaters and need support for this.

Who I amHi, My name is Joram and I'm a 3th year electrical engineering student from the Netherlands who likes to make projects at home, mostly projects which involve lighting / LED. Project desciptionThis display is made to connect to a DMX ledstripcontroller. because a display and buttons uses a lot of pins I decided to use a TM1637 module and extend the standard module with 4 buttons and 3 leds. the entire module is controlled by only two data lines (and power). In the link to the documentation you will find all documentation, schematic, gerber files, Bill of materials and a complete 3d model. This model is an upgrade of the first version and is a lot smaller and uses SMD components. Words to PCBWayThe first versions of this projects were made with PCBs from PCBWays and they turned out great. PCBs were completed in 2 days and arrived a week later.Thank you!

DESCRIPTIONMy name is Elmar Peters and I'm from the Netherlands where i study power electronics at TU delft.I design power converters and for testing these power converters an electronic load is required. An electronic load is the opposite from what a power supply is. Where a power supply delivers an electronic power with a certain voltage and current, an electronic load sinks an electronic power. An electronic load can be configured to draw a constant current, power, act as a constant resistance or keep the voltage across the terminals constant. TECHNICAL DETAILS The load I designed dissipates power is a single mosfet in a to-247 package. This mosfet is attached to a large CPU heatsink mounted on an extruded aluminium housing. A maximum of 300W can be dissipated where the current and voltage are limited to 15A and 300V.The front panel of the load is made out of a PCB. The front of this PCB gives a nice user interface, the back of this PCB is used to mount all components required for controlling the load. Incoming voltage and current is measured and used to control the dissipating mosfet. The user interface consists of a rotary switch that can be used to select different modes and configure the limits for the current and voltage. All setpoints and measurements are shown on an OLED display.The load also has a wifi module for connection to a PC. This is great for configuring the load in automated test setups. Words to PCBWayI'm looking forward to get the PCB for this project produced at PCBWay!

### DESCRIPTION ( Introduce yourserlf and your project)Hello, we are Andy, Branco and Jonathan. We are 4th year electrotechnology students. This is our endproject.We are making a machine that makes 3d printed objects smoother by heating a chemical fluid. We have our main pcb and the machine itself, but we need a second pcb to connect a little bit more IO from our microcontroller to our raspberry pi.### TECHNICAL DETAILS (With project photos)This is our machine almost completedly assembled. The only things missing are the PT100 and the heaters.This is our machine from the inside. The ribbon cable connects our current pcb with the Raspberry Pi. The 2 fans in the back of the machine are for internal cooling, the fan on the side is to suck the fumes out of the enclosure where the 3d print is seated.A close up of our pcb. The microcontroller is an ECIO40. We use an old PSU to power everything except for the RPi, which is powered by its own adapter.### Words to PCBWayWe need a small pcb, without the components. We have the parts and can solder it ourselves. This is the pcb we need. The pcb is 2 layers, and is 86mm by 66mm.

About SHA2017SHA2017 is a non profit outdoor Hacker camp taking place in The Netherlands in 2017 on August 4th to 8th.It is the successor of a string of similar events happening every four years. These are GHP, HEU, HIP, HAL, WTH, HAR and OHM.Similar events are EMF Camp 2016 in the UK, CCC Camp and congress in Germany. The location is the Scoutinglandgoed in Zeewolde, 55km east of Amsterdam.The festival is organized for and by volunteers from and around all facets of the international hacker community.Knowledge sharing, technological advancement, experimentation, connecting with your hacker peers and of course hacking are some of the core values of this event.About SHA2017 BadgeWe are designing a badge to help our visitors and volunteers navigate the camp. It will feature an e-paper display for visibility in bright daylight, as well as a powerful ESP32 module for wireless development.Over the past months, the badge team has been hard at work designing a badge centered around a beautiful e-ink display and Espressif's brand-new ESP32 microcontroller, the improved version of the popular ESP8266. This makes the badge flexible enough to write your own applications for. As most of us like to tinker with hardware and software, the badge will be an open platform to experiment on. The design is already fully open-source and available on github and the SHA2017 wiki. It will utilize touch controller inputs, a decent sized battery that should last at least a day and the most unique feature, an e-paper display that is reasonably fast and most importantly, easy to hack.First and foremost, the badge will have a 2.9" e-paper display (296x128pixels). This is a 1-bit monochrome display which supports partial refresh, and with some firmware hacking we are able to emulate a larger bit depth and increase its responsiveness.Footprints for six SK6812 or pin-compatible addressable LEDs are placed above the display. These were chosen to match the official SHA2017 design, which includes a freedom flag consisting of six RGB colours based on the SHA1 hash of some text or data. Using the ESP32's hardware SHA1 unit we may be able to display the colours corresponding to for example the name on the badge.Any interactive badge needs input. To keep the badge a single-sided load for production, we opted for eight touch buttons (up, down, left, right, a, b, start, and select). The battery will be decently sized, and should be able to last for at least a day when used interactively. The battery life will of course be better when only used as a badge, thanks to the e-paper display :)
