Steve made this 6 volt 5 watt solar charge controller project, that is available at Github: Here is a 6 volt 5 watt solar charge controller project using a dedicated printed circuit board from dirtypcbs.com and an Arduino pro-mini. The board uses sot-23 low RDSon P channel mosfets (Si2369). It has voltage and current sensing, and 3 […]

A signal amplifier module for HF
Marcus Jenkins blogged about his radio frequency amplifier project he made using DirtyBoard PCB’s In building QRP HF radios, having an RF signal level amplifier building block is handy. You want 50 Ohm output impedance, some reasonable gain, supply voltage of the usual 10-14V and ease of building using standard parts from your parts bin. Some […]
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 […]
Mikey’s first DirtyPCB experience
Mikey shares his first impressions with DirtyPCBs: Yes, exclamation mark and lots of yelling! The PCB’s has arrived, lets have a look at them. At first glance they look very good, silk screen is fine, both on top and bottom. The outline of the board feels smooth with a sharp edge, just as it should […]
How to develope for the ATtiny85 without becoming insane
Lembke writes: I like the ATtiny85. It is small, comes in a solder friendly DIP 8 case, has 8k Flash + 512 Bytes Ram, 5 to 6 IO pins at 8 MHz with no external parts. But developement is a pain: no serial (ok, it is possible but needs ports) and debugWire is even more […]
DirtyPCB BeagleQ
HouseOfBeck shared his DirtyPCB BeagleQ in the project log forum: The BeagleQ is a wifi enabled wireless intelligent bbq smoker controller based on the BeagleBone Black controller. This device is designed to control a fan connected to the smoker’s input vent/damper. Using a temperature probe placed in the pit the controller can read the pit temperature and […]
ESP8266 relay board
renze shares his ESP8266 based relay-switch board in the project log forum: Functions – 2x relay output – DHT22 temperature and humidity sensor – GPIO header – On board 3.3 volt regulator Project info at RN+ site. The design files and firmware are available on GitHub.
ESP8266 WiFi LED dimmer Part 8 of X: Version 2 of the PCB design
Quindor blogged about his ESP8266 WiFi LED dimmer project with DirtyPCBs: With the help of kind internet folks I was able to get a fritzing part for the new voltage converter I wanted to use to try and make a smaller board. A few weeks ago I sent my new ‘panalized’ design to dirtypcb’s and I got […]
DirtyPCB’s based project: TDR pulse generator for testing coax
Marcus Jenkins blogged about his TDR pulse generator build: I saw an excellent YouTube video from Alan W2AEW and thought I’d have a go at making a prettier version of the tool myself. After all, checking 50 Ohm coax cables is a pretty common need for an amateur radio enthusiast. Alan’s video says it all, but here’s […]
DirtyPCBs two layer ENIG PCB closeups
DirtyPCBs two layer ENIG PCB review by manis404: The standard service is $14 for 10 boards. You can have the pads ENIG finished for $15 more, which brings the total cost to $29 for 10 boards, shipped. It is still an excellent deal. The quality is excellent too, as the closeups below illustrate. See more […]
KF5OBS’ Dirty PCBs review
KF5OBS’ first PCB manufacturing run with Dirty PCBs: So what’s the quality of the board? For $ 33 delivered I naturally didn’t expect much. But I was wrong. First off, I received 12 PCBs. So the Protopack definitely worked in my favor over ordering a guaranteed 10 pack for twice the price. Asides from some […]
DipTrace export settings for Dirty PCB
As a follow up to the PCB layout design with DipTrace post, KF5OBS blogged about on how to set-up DipTrace to export a PCB layout correctly for Dirty PCB: Dirty PCB offers – as the name implies – dirt cheap PCB manufacturing. The trick is a very low profile and a straight-forward system that needs minimum […]
DirtyPCBs: HDC1000 temperature and humidity sensor breakout, with Arduino library
Francesco Truzzi published a new build: a breakout board for the TI HDC1000, a tiny (8BGA) temperature and humidity sensor The boards were again fulfilled by DirtyPCBs, perfect for this kind of small projects. So here are the pictures of my board and here are the features: Address selection jumpers: ADR0 and ADR1 are tied to […]
DirtyPCBs: C64FC 16K edition ready
Stian Søreng writes: A stack of release candidate 3 boards of the C64FC are on my desk, and a few changes have been made since RC2. We’re talking 16K support, software switches to select 8K/16K cartridge, cart disable support, bugs fixed and patched. I also want to give a good shoutout to DirtyPCBs for their […]
DirtyPCB LSF0204 breakout board – a bidirectional, multi-voltage level converter
Francesco’s LSF0204 breakout board, a 4-bit, bidirectional, multi-voltage level converter: I needed a small, fast and reliable multi-voltage level translator (mainly for connecting ESP8266 boards to the Arduino, got tired of resistor networks pretty quickly) so I built a breakout board for TI’s LSF0204(D). Datasheet and info here. The LSF0204 is a nice little chip. […]
DirtyPCB Pico-Kubik quadruped robot
Pico-Kubik, the tinniest quadruped robot with Micropython on board by Radomir Dopieralski: This is the fourth quadruped that I’m building, after Kubik, µKubik, and Nano-Kubik. This one literally fits in the palm of your hand (you can see it next to a LEGO brick on the photo). It’s going to run on Micropython on a VoCore […]
Avoccado° Nora, batch of PCB from DirtyPCBs
Natalie Kane writes: Nora is the most recent approach to cram up everything of the recent prototypes but use only 2 layers and populate all of the components on one side. Nora is the smallest board with a LiPo charger yet, measuring just 23.5 mm x 23.5 mm. Nora is the first version having the […]
“Dirty” isoUSBRS422 boards just arrived
@alper_yazar tweeted picture of his “Dirty” isoUSBRS422 boards.
Free PCB the other way around
Last week Sjaak got a free PCB and a small SMD antenna from a user called Claude on the esp8266.com forum . Claude made the board using Dirtypcbs.com. As Sjaak is a huge fan of QFN chips he went straight to his mancave and started to assemble the board. Close-up of the soldered QFN chip under a USB microscope. There were […]
