I have been trying to design a K9 for 3D printing for a while, even using Fusion 360 getting the body designed has been a stumbling block, On Facebook, there is a k-9 builders community and a link to an OneDrive account with 200 x 200 sliced STLs. I have […]

At work, I am trying to make some automated test equipment, (I also have some personal test equipment to automate as well). At work I use MS Windows 10 for my laptop, home I use macOS, and for embedded test equipment I am planning on using Raspberry Pi and Pi […]
A fair while ago Swindon Makerspace started a group project called LogoBot, a cheap, expendable and extendable easy to build robot for playing with. Even longer ago I bought a MiroBot from kick-starter, it had lived in a box, and parts of it had got damaged. Tamarisk showed me and […]
I picked up a 37 in 1 box sensor kit from china, it includes basic components and sensors, and is compatible with Arduino and Raspberry Pi The Package Included (their description): Small passive buzzer module KY-006 2-color LED module KY-011 Hit sensor module KY-031 Vibration switch module KY-002 Photo resistor […]
Most of the stuff you will need to do the electronic projects I do on this site can be got by going to Amazon (I have affiliate links), I know I have mentioned the Oomlout Starter Kit for Arduino, However I fear that this is discontinued 🙁 The Oomlout Starter […]
https://www.jeffgeerling.com/blog/2017/raspberry-pi-zero-w-headless-time-lapse-camera https://github.com/geerlingguy/pi-timelapse ==== Set up pre boot ==== Since the /boot partition is accessible by any computer with an SD card reader, wifi configuration is now much simpler. A typical wpa_supplicant.conf file is: ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 country=«your_ISO-3166-1_two-letter_country_code» network={ ssid=”«your_SSID»” psk=”«your_PSK»” key_mgmt=WPA-PSK } For headless setup, SSH can be enabled by […]
A while ago I made some videos of writing a Raspbian to a SD card for use with a Raspberry Pi, I am on a mac, which makes my life much easer as there is now an awesome tool called ApplePi-Baker that makes making SD cards much easer than DD […]
Today like last year I went to Bristol for the mini maker Faire (unlike Manchester and Liverpool Makefest this one still pays the silly amount of money to use the make branding). Unlike last year @Bristol charged at the door (£3 pp which may not sound like a lot, but […]
I downloaded Random Nerd’s Build a Home Automation System for $100 and started testing it out, A while ago I aquired a Fish Dish (not sure where from), It’s a small PCB that fits on the GPIO header of the Raspberry Pi. I set up NodeRed and MQTT on the […]
The Arduino IDE serial console sucks! (the entire Arduino IDE kind of sucks, but one fix at a time). I first tried to use the native Minicom package, the most up to date one I found was version 2.2 (compiled Mar 16 2007), it can be installed and set up […]
To facilitate remote tech support, we need a server some place safe, like this one. We also need to give the Raspberry Pi a username and password so it can log in (this article was used as a guide). But why would we want to do this? I am looking to […]
A while ago work bought an Ultimaker 2 to produce cool things at work, A Raspberry Pi B+, and Pi Cam were also acquired for it with a view to using OctoPi (a copy of OctoPrint developed for the R-Pi). OctoPi can be downloaded from the official mirror, and burnt […]
What Do I Need? Raspberry Pi unit with Raspbian installed Ethernet connection to R-Pi USB Wi-Fi Stick In addition to the above items, you will need to check the configuration of the Wi-Fi network you plan to connect to, you will need the SSID, password, and encryption type/method (e.g. the […]
The Raspberry Pi is an awesome little computer that can feed either a composite video feed, or a HDMI output, however most of the time I want the thing headless, If you set up Rasbian the same way as I showed in the last guide then this will work for […]
I have used a number of Raspberry Pi’s for things, and despite there being more than one linux distribution available for the R-Pi I have not tried anything other than the Debian based Raspbian “wheezy”, These instructions are written assuming that you are using a Mac Running Mountain Lion. Raspbian […]
The Raspberry Pi A, and Raspberry Pi B both had a composite video out, on an composite video plug (RCA), the new model B+ uses a 4-pole socket which carries both audio and video signals. This style of connector is sometimes referred to as “TRRS”, which stands for “Tip-Ring-Ring-Sleeve”. The […]
For my boat automation system I plan to use RJ45 sockets and cat 5 cable for interconnecting the master and the nodes. Some nodes will have their own 12 V supply for larger loads, but ones that are just for switches and other transducers (sensors) will need to have 12 […]
I have been playing with OpenSCAD to make design 3D printed parts for use with the Raspberry Pi, I found one online, and have made some changes, have a look at the OpenSCAD R-Pi model. In the model are both A and B, to choose the one you want you […]
Tom and Jan of nbWaiouru have a really awesome thing on their boat called Empirbus, it is like a home automation system, but on a boat! Empirbus NXT is a new product line, based on more than 10 years experience in power distribution using Digital Switching. EmpirBus NXT is an […]
