It can be programmed in C/C++ and Python. My second issue is that when you have done your breadboarding, and want to go to a permanent project, which does not always need a dedicated PCB, you are now required to either live with things on a breadboard, scary to say the least or have a spider with many modules and wires, in a box or partly on protoboard etcMy Solution, the ESP32-S DEV Board, in Arduino Uno form factorMy solutionWhile not the most elegant, personally I really like the size, and layout of the humble Arduino Uno, with its standardised pinouts, and a large number of addon shields available for the platform. It comes in a syringe so you can dab a little on both pads (does not need to be supper neat), place the part down and reheat with the hot air gum.

Along 3 years I have been trying several leg mechanism, at first I decided to do a simple desing with tibial motor where placed on femur joint.This design had several problems, like it wasn't very robust and the most importat is that having the motor (with big mass) that far from the rotating axis, caused that in some movements it generate unwanted dynamics to the robot body, making controlability worse.New version have both motors of femur/tibial limb at coxa frame, this ends with a very simple setup and at the same time, the heaviest masses of the mechanism are centered to the rotating axis of coxa limb, so even though the leg do fast movements, inertias won't be strong enough to affect the hole robot mass, achieving more agility.Inverse Kinematics of the mechanismAfter building it I notice that this mechanism was very special for another reason, at the domain the leg normally moves, it acts as a diferential mecanism, this means that torque is almost all the time shared between both motor of the longer limbs. "); Serial.println(" 'i'-> PRINT INFORMATION. "Battery Holder PCB" is the second board that holds the main power source of this whole device, two Li-ion cells.IP5306 setup is used, for charging, there's a USB Type C Port and also one for discharging.PCB DesignAfter getting the rough Idea of the shape for both the Front and back PCB, I designed two separate boards, Front Panel and Battery Holder PCB.The Front Panel PCB contains mainly the screen and buttons, it has mounting holes for adding the Battery Holder PCB and Screen holder.The Battery Holder PCB was simple as well, it's an IP5306 Based board that controls Li-ion Charge and discharge cycle as well as gives stable 5V output for Raspberry Pi and screen to power.Both PCBs are made in such a way that they can be connected by three PCB Standoffs making the PCBs the main body so we don't have to use any sort of 3D Printed cover for this version.PCBWAYAfter completing both designs, I exported their Gerber data and sent it to PCBWAY for samples.A White solder mask and Black silkscreen were used for this project.I received PCBs in a week and the PCBs were nice as expected.I like the quality of the white solder mask, it was a tough sample to manufacture as the silkscreen that I have laid out on this board was not completely symmetrical and I also added a rectangular void in the middle region which was not like normal PCB layout but PCBWAY did an excellent job of manufacturing this PCB with no error whatsoever.check out PCBWay service for getting great PCB service at less cost.Solderpaste Dispensing ProcessNow the first step is to add solder paste to each component pad one by one.To Apply solder paste, I'm using a Solderpaste Dispensing Needle with a Wide syringe, and the solder paste I'm using is a regular solder paste consisting of 63% Tin and 37% Lead.We first applied solder paste to the Battery board and then did the same for the front PCB.Pick and Place ProcessAfter applying Solderpaste we move on to the next step which is to add componenets to their assigned location.I used an ESD Tweezer to place all the components on both the Front and Battery PCB.Hotplate Reflow ProcessAfter the "Pick & Place Process", I carefully lifted the whole circuit board and placed it on my DIY SMT Hotplate.the hotplate heats the PCB from below up to the solder paste melting temp, as soon as the PCB reaches that temp, the solder paste melts and all the components get soldered to their pads, we lift the PCB and then place it on a much cooler surface for a little bit, to cool down the heat of PCB.Adding SMD Rpi GPIO Header and CON2Next, we add the 40 Pin Female Header Pin on the Front Board's bottom layer using a soldering iron, this will take a while as we have to manually solder each pin to its SMD Pad.After adding Header Pin, we add CON2 JST Connector to the 5V and GND pin of the board, we later connect a JST Wire Harness to this CON2 for powering the RPI with Battery Board.SMD Li-ion cell HolderNext, on the Battery Holder PCB, we add Li-ion Cell 18650 SMD Holder in its place by using a regular Soldering Iron.Battery Board TestAfter adding the SMD Cell Holder, we add two 3.7V 2900mAh Li-ion cells in the Cell Holder, making sure to place them in the right polarity.Next, we press the Main ON OFF Button and measure the voltage at Output Terminals which should be more than 5V.Adding Screen with Front PCBWe now add the PAL Screen on the Front Panel by using two 3D Printed Screen holders and a couple of screws.After this, we connect the Screen's VCC to 5V of the Front Panel board, GND to GND, and PAL port to PAL port connector given on the left side of the board.Adding Side Holder/Grip with Front PCBNext, we add two Hand Grips to the Front Panel, these grips are 3D Printed and are mounted by two M2 screws each.Raspberry Pi Zero Merge with Front PCBIt's time to place the Raspberry Pi Zero in its Header socket.We first solder a wire to the PAL port nearby the Raspberry Pi zero area.Next, we secure Raspberry Pi in its place and add solder wire to the PAL port of the Raspberry Pi so we can attach the wire easily to it.Front PCB and Battery Holder PCB MergerWe now start the final assembly by first adding Three PCB Standoffs to the Battery Holder PCB.Next, we place the Battery Holder PCB on the Bottom side of the Front Panel and use three M3 Screws to connect both PCBs.Connecting Battery Board with Front Panel through JST wire harnessAt last, we add a JST wire harness to the Positive and Negative port of the Battery Holder PCB so we can connect this wire harness with the CON2 JST connector on the Front Panel.RESULTHere's the result, a handheld console that is powerful enough to run a bucket load of old retro games like Super Mario, Pokemon games, Contra, etc.But before doing that, we first need to set up the RECALBOX OS.Setting up Recalbox OSI used RECALBOX OS to run this setup.Why Recalbox OS, why not Retro Pi or another OS?well, the answer here is simple, recalbox is an easy-to-use OS that comes with a lot of Free games pre-installed.Also, it's small and can run on low-spec raspberry pi systems.like in my case, I'm using a Raspberry Pi Zero W which has 512MB ram.it's not exactly a powerhouse but it can handle a few retro games without breaking a sweat.Installing it is also very easyDownload the Raspberry Pi imager.Select the right OS for your device, which would be RecalBoxselect your system which is Rpi zeroRaspberry pi imager will do your work of downloading and installing the RecalBox on the memory card.After installing the RecalBox os, you need to plug your Raspberry pi setup with a Keyboard as the first boot always requires a keyboard.After plugging the setup into an HDMI monitor and booting it, the RecalBox works like a normal emulator.Editing Config File- GPIO Enable and PAL DisplayThis console has GPIO Buttons and PAL Display that we need to configure through two different files.Before SSH into the PI, we open the network settings in the Raspberry Pi and connect the recalbox to a local network for the internet.

This article covers the types of fluxes available, the advantages and disadvantages of each, and options for flux removal. And remove the access soldering residue using alcohol.Mounting the heatsink:STK comes with an aluminum back which acts like a heatsink but for heavy load it is not enough. Serving the maker community since 2013, focusing on SMT and SMD based stencils for solder paste electronic circuits and electronic design applications. Did you make this project? While it is not specified in NB-IOT applications, I have also tested it on a moving vehicle, and it worked. In the kit, you will get the following items:1. EN 29454-1:1993 and ISO9454-1:1990, the No-Clean and Lead-Free fluxes have a classification of 1.2.3.B. Both the top and bottom parts are printed with support structure, so we have to remove them before final use. For example, 19200 translates to the 200th day of 2019, or July 19, 2019. It also provides automatic turning ON during the night. Those who have a checking or savings account, but also use financial alternatives like check cashing services are considered underbanked. The shelf life of a product can be found on either the technical data sheet (TDS), available on the product page, or by looking on the certificate on conformance (COC). With more than 10.6 million unique visitors over the last year, Practical Machinist is the most visited site for metalworking professionals. That was an improvent since with the old mechanism tibial motor had to hold most of the weight and it was more forced than the one for femur.To visualize this, for the same movement, we can see how tibial motor must travel more arc of angel that the one on the new version.In order to solve this mechanism, just some trigonometry is needed. Indeed the VM pins on the protection chip should be connected to the charger GND which needs to be disconnected from the battery GND, and no over over-discharge protection is provided for a solar charged application, as this chip is intended to be used for short high current bursts connected to a low current constant source such as a camera flash which uses regular batteries to provide a reliable power source.Nice try and a good use of a small part of the massive oversupply of plastic bottles, but small battery management circuit boards are easily available, such as the TP4056 board which can be obtained from amazon or aliexpress among other places.P.S. Careful not to drag the braid over the pads, which can scratch. "Front Panel PCB" as its name suggests is the front part of the console, It holds the screen in its place and has 13 SMD Buttons.It also contains the Raspberry Pi Header Pin socket which is mounted on the bottom side of the board.
