DirtyPCBs adds full range of steel and framed stencils

  Stencils for solder paste and red glue are now available in a bunch of standard sizes for solder paste/red glue dispensers. You can choose from all the options offered by our favorite stencil maker: Purposes: Solder paste for surface mount component reflow process. Red glue for two-sided or through hole board wave soldering process […]

DirtyPCBs site update with encrypted https connections

  DirtyPCBs.com now supports secure, encrypted access with https://DirtyPCBs.com. We used a free certificate from Let’s Encrypt and the process was almost painless. You’ll need to add the ‘s’ to the address manually to access the secure version of the site. Https may become the default eventually. It’s trendy to force everyone onto https these days, […]

Bi-directional voltage level translator – Board house test

Lukas Fassler from Soldernerd shares his experience with DirtyPCBs: I can think of a lot of situations where it could be useful. But the main reason for this project was to gain some experience with getting a PCB professionally manufactured by a board house. For several years I have done my own designs but I always milled […]

Capacitive battery charger

Marcus Jenkins made a capacitive battery charger using Dirty Board PCB’s to revive rechargeable batteries: This is really a basic, bare-bones circuit. I’ve prepared the PCB with a view that it could be used as a module in a rather more-sophisticated charging system. You could imagine using a microcontroller (e.g. Arduino, PIC, etc.) to monitor […]

Lab LED constant current controller board

Ladvien blogged about his Lab LED constant current controller board project he made using DirtyBoard PCBs: A little lab controller PCB I’m working on. It centers around four high-power constant current circuits meant to be driven by an Atmega328’s PWM. I hate working on anything mechanical in dim light; comes from dropping parts down under […]

Souliss device ESP based combined with 3D Printing

Juan has been working on a Souliss device ESP based project, that is available at Github: With this board we can control 3 monocolor led strips (or 1 RGB), can host multiple sensors and options to come by external modules or internal conectors, Im working on this modules now. For now this board can host a […]

Making a PCB business card

Ilia Baranov has designed a reference business card: Back of card includes: Ruler in both 1/10″ and mm. AWG Hole size gauge (not super accurate due to plating, but that is unavoidable) Resistor/capacitor/inductor/diode sizes Common surface mount component sizes Common electrical symbols and shortcuts/equations Common conversions Trace size comparison Quote from Dune! Project info at Mr.Robot […]

Raspberry Pi and ARM uC Breakout + DirtyPCBs mini-review

hipfan75 writes: Briefly, it’s a Raspberry Pi v1, Model B, Rev2 breakout with an STM32F030 microcontroller connected to the Pi UART, with all GPIOs for both broken out. There are also connectors for an NRF24L01+ module, a 12V boost module, and 315/433 Mhz wireless transmitters. One board will serve as my Garage Door Controller, while […]

Review: Dirty Circuits Done Dirt Cheap

DirtyPCBs detailed review by Gee_Rabid_Inventor:  Often design and research is and expensive business, especially when dealing with technology that your are unfamiliar with. A big proportion of this is PCB manufacture and I have spend a few years looking for a low cost reliable method for PCB production. The most cost effective method is to […]

Pro mini shield

Albert blogged about his mini pro shield project: Just finished my little mini pro shield which makes it a little easier to use the mini pro with projects and it now also makes the mini pro easier to use with test and trial projects. The shield has a 3.3V and 5v power supply on board […]

DirtyPCBs based project: Isolated USB Serial Interface

Steve Rodgers just completed another project using a DirtyPCB order, an isolated USB serial interface, that is available at Github: Here is another project I just completed using a Dirty PCB order. It’s an isolated serial port using the CH340G chip and 4 Silicon Labs Si8410 digital isolators. Isolating the serial port ground from your […]

Arduino time lapse – camera pan device

An Arduino camera pan device project from Bajdi Electronics: I own one of these small action cameras (SJcam SJ4000). I bought it because it’s small, and easy to take with you wherever you go. To make nice stable videos I mount it on a mini tripod. This got me thinking that it would be fun to have […]

Low noise amplifier – 100MHz to 300MHz

In this video Hpux735 demonstrates his Sky67015 LNA breakout board: A Low noise amplifier (or LNA) is a special amplifier that is designed to be the first amplifier in a receiver. It is vital that the first amplifier of a receiver has low noise, because the noise of the whole system is dominated by the first […]
