This is an alternative, to replace the original two 41464 dram on pcb.It can use 8x 4164 or 4264 drams, and is ready for 41256 but locked in 64Kx1 page mode.I want to note that I never built it, so anyone it's doing it is with your own risk.

With this ATX Power Supply Tester board you can test any modern and old PC power supplies. Only a switch (you can skip it), a handful of resistors, LEDs as well as an ATX Power socket are needed.It gives feedback on the all the power and control lines.Easy to use.

Practice makes perfect and soldering needs a lot of it...This 100x100mm board contains all the features you will need in order to practice your soldering, improve your skills and boost your confidence. Depending on your soldering experience, it comes in handy both as an exercise tool and as a quick way to warm-up before a soldering session.Watch my video for all the necessary details: https://www.youtube.com/watch?v=czXJevPWIsA Main features of this soldering practice board:- Castellated holes (plated half-holes) in four (4) different sizes, along all the edges of the board. - Six (6) types of pads in a total of eleven (11) rows, with different heat dissipation characteristics.- Large pads with very high heat dissipation, from 2.5x2.5mm up to 7.0x7.0mm sizes.- Tiny pads in four (4) large groups, for precision soldering and pad bridging practice.- Cold section with four (4) different types of pads, interconnected with traces for varying heat dissipation.- Rails in various widths, for long, uniform and continuous soldering using different tip sizes.- Battery connector section with mounting holes for XT60, XT30, PH2.0 and BT2.0 connectors.- SMD section for surface mounted components, with different spacing.- Board mounting pads for a RX5808 module - the pad spacing should fit other surface-mounted boards too.- Antenna connector pads for SMA, MMCX, IPEX and uFL connectors.The spacing of the pads and the castellated holes becomes smaller as you reach the end of each row, for more challenging soldering conditions. You can add wires between the pads to increase heat dissipation even more.The XT60 holes can be used for holding the board with the alligator clips of helping hands. There are also mounting holes on the board for your own custom stands/holders. Check the info sheet for more details on my Ultimate Soldering Practice Board: http://www.mutefpv.com/uspbinfo Ordering details:- Join PCBWay here: http://www.mutefpv.com/pcbway or Sign-in and add my design to your cart.- Make sure the "castellated holes" option is checked / enabled (on checkout).- Choose your desired surface finish: HASL will be like having pre-tinned pads. OSP adds an organic coating on the copper pads that goes away as you apply heat with your soldering iron. If you want something more premium, go for the ENIG (immersion gold) option.- Insert the quantity you want.- Select the "solder mask" color you want (this is the color of the PCB board).- Select the "silkscreen" color you want (this is the color of the text, logo and borders on the board).

In this project as you can see we used a custom-made PCB board and the ATmega328p micro controller. The board is specially design for this project and for small RC models. You can simple control it from your Android phone or tablet via Bluetooth. From the Android application you can also turn on/off the front and rear lights and play a horn sound! For our RC model we used only 3x1.5V AA batteries!Project updates,code, schematic and other files can be found here:http://www.ardumotive.com/arduino-bluetooth-rc-car...http://www.ardumotive.com/arduino-bluetooth-rc-caren.html

A shot at making a good metal/battery spot welder, which will be controlled by an Arduino Nano.The PCB design is pretty simple, therefore one should not have a hard time replicating this project to fit their needs.It is not necessary to follow our example exactly, it is just there to give you some ideas to create something unique of your own.You can find why it is necessary to have one if you are building medium to large scale projects, by reading the PCBWay Blog HEREYou can also check the project's full description by visiting Hackster.ioHappy welding!https://www.pcbway.com/blog/technology/What_does_a_spot_welder_do.html

### DESCRIPTIONA tiny board to controll rgb stips from your pc.### TECHNICAL DETAILS / COMPONENTSA little board I made based on an ATSAMD21G18 ARM Cortex M0+ processor.It has 6 addressable RGB headers and 4 normal ones, one of which supports RGBW or RGBUV.There is also a controll software that goes allong with it, but it's still under development.Currently it looks like this.The software is also compatible with ASUS AURA products (M/B, GPUs RAM)using the AURA SDK, and serial for linux (yeap rgb software on linux) and Cooler Master Keyboards and mouse.### LEARN / TOPIC / BUILD INSTRUCTIONS
