More than a few years ago, I bought myself a Remote Control boat, a Kyosho Wave Master: The WaveMaster is a semi scale model of an F-1 tunnel hull racing boat. Tunnel hulls work by trapping a cushion of air between the hull and water to reduce friction which allows […]

Following on from trying to program the LinkIt ONE on Mac, and Windows, I went looking for further information, I managed to find some information on the IDE GitHub page, I will compare how easy it is to program each of them with Blink.ino. My mac is set up as […]
Tas, Bob and I headed over to the National Model Engineering and Modelling Exhibition 2015 in Harrogate.
Following on from the Mac instructions, I have also set up MediaTek’s LinkIt™ ONE on a Window Machine, Setup Download the MediaTek LinkIt SDK for Arduino Windows. Unzip the downloaded zip, right click on the installer “mediatek_linkit_sdk_(for_arduino)-1.1.05.exe” and “Run as administrator” Change the location on Screen two to the location […]
A few weekends ago, HACMan, Tas and I were at MakerFaire New Castle. One of the exhibitors there was MediaTek, showing off their range of LinkIt Wearables / IoT (Tnternet of Things) development boards. I have managed to snag myself a LinkIt One development board kit: Optimized performance and power […]
I have finally got round to trying to Automate the hot water pump on the boat, using what I found out about the DS18B20 one wire Waterproof Temperature sensors from the Arduino Data logger I wanted to try out controlling the pump, (the same PCB will be used for other automation […]
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 […]
At work we had need for a multiple temperature logging device. Using one of my cheap Chinese Arduino Uno clones, some DS18B20 one wire Waterproof Temperature Transducers (like these ones), a cheap Ethernet / SD card shield (like this), and a DS1307 RTC (Real Time clock) (link). The DS1307 RTC […]
I found these Arduino Uno clones (link) on Ali Express for £2.16 each with free shipping from china, I can’t even get Diavolino for that little (Also a Diavolino needs a RS232 / FTDI or something as well). These clones come with something different, rather than the usual FTDI they […]
A Stevenson screen is an outdoor enclosure to shield meteorological instruments against precipitation and direct heat radiation (sometimes called a radiation screen) from outside sources, while still allowing air to circulate freely around them. The World Meteorological Organization (WMO) agreed standard for the height of the screen is between 1.25 […]
Similer to how I deal with keeping Eagle in sync between multiple machines, I try to do the same with the Arduino IDE and Processing. In my dropbox folder I store my projects in a sub folder called Projects, and in there I have a folder called “_Vitamins” (the _ […]
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 […]
I have a MacBook Pro, and a Windows XP Virtual machine, and use Eagle at work on another windows machine, The work machine and my mac are both sharing a Dropbox folder, (Alex Lang has instructions on how to install Eagle on Windows). (If you use Eagle 7.1.0 you can […]
My test print of the Maritime Research Institute Netherlands (MARIN) No. 37 profile. The Kort nozzle is based on the one from Tomi Salo put on Thingiverse, I didnt make any alterations to the .dxf file, and a few alterations to the .scad file. I have sized the nozzle to […]
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 […]
I have been looking to build an ROV (underwater Remotely Operated Vehicle) for a while, There will be other blog posts on this in my blog some where. I have been looking over the designs for the OpenROV and have signed up on the forums. there is one guy on […]
As part of my R-Pi K-9 I want to have a web browser interface, (also because I want to build an ROV) I don’t have a beaglebone black. Using a web browser as my interface will allow me to use my recently acquired iPad to control it, I want to […]
Sooner or later you will find something that you want to attach to something else, and if any of those some-things is a camera or a tripod, you will soon meet the challenge of WTF? its almost an M6? what the hell is it? Say hello to the 1/4-20 UNC, a […]
Following on from How electrically noisy are Servo motors – Pt1 where I subjected a Tower Pro MG996R and a Tower Pro Microserver 9g to the ERAD (Emissions Radiated) test. I am now going to do the ECON (Emissions Conducted) test. The ECON test is a scan between 150 kHz […]
At work my day job is as an EMC test Engineer, on of the Tests we do as part of EMC compliance testing is a Radiated Emissions scan between 30 MHz and 1 GHz. There are two sets of emissions limits that are most commonly tested for (others are more […]
Normally when using Eagle Light, you only get to see one sheet, and you can not add additional new sheets to a schematic file. However there is a sneaky trick…
A while ago I bought a DIY Arduino Geiger Counter kit from ebay and a SBT-11A Russian Geiger counter tube. The SB-11A is a very sensitive alpha tube, comparable to the LND 7317 in some ways. It also seems sturdier and is certainly cheaper. The data sheet gives: 44-49 cps/uR/sec, so the CPM to […]
As some of you know I may be a bit of a geek, one of the tools I use is the Teensy, it is very smiler in use and specification to an Arduino while not being a pure clone unlike the Diavolino. My preferred member of the family is the […]
