Like the bearing size code, resister values for LEDs is something that I keep needing to work out, or just go back to my nominal somewhere between 200 Ω and 1 kΩ rule of thumb. While I could work it out every time I need it using and then chose […]
I just realised that in Part 1 and Part 2 that I didnt discuse how to go from Datasheet to Fusion 360, While I am not going to cover how to do the drawing in great detail, there are plenty of sites which tell you how to make drawings in […]
I found some cheap small microswitches on AliExpress, working backwards I found the same switch part numbers, and subsequently found a Switch Data sheet for the same size part. I use a mix of Fusion 360 and KiCAD for design, so I CADDed up the three flavours of microswitches, using […]
I have started designing assembles in Fusion 360 using T-Slot, a lot of head scratching on how to make use of it at arbitrary lengths in my designs… I started by making a 20mm length of T-Slot as its own model in Fusion 360; This is model has all of […]
This week we will be having a play with a 74HC595, the Data sheet lists it as an 8-bit serial-in, serial or parallel-out shift register with output latches; 3-state.” In other words, you can use it to control 8 outputs at a time while only taking up a few pins […]
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 […]
I have now been to Bletchley Park twice. In the gift shop they have a Build your own Enigma-E Kit: The Enigma machine was the German cipher machine used to encrypt their WW2 communications and systematically cracked by the Bletchley Park Codebreakers. This highly detailed replica design gives you the […]
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 […]
Today’s Makevember There seems to be very little consensus on the arangement of the colours of the buttons on the back of K-9, K9 has a 4 x 3 array of buttons on his back, I am using this image Binary kitten got me from the k9 at the Doctor […]
As part of my Weather Station Project, I want to be able to deploy it anywhere, including places with ZERO electrical power. I found this Wind Turbine on ThingiVerse, however it is released under a Attribution, Non Commercial, NoDerivs (CC BY-NC-ND 3.0) licence by 3dprintable, which means I can’t edit […]
Tas, MiniBoyGeek and I had a quick walk round the Steam Punk Spectacular at the Swindon Steam Museum (will have to do Photos of that some other time). Podpad Studios were there with some of their cool steampunk stuff, and some one (not sure who) brought a Caravan. The rest […]
A while ago I backed the kickstarter campaign for Particle (formerly Spark)’s Electron board, a IOT (internet of things) with a built in 3G modem (2G are available) with global data coverage, recently they shipped, Setup was as easy as getting it out the box, wiring it up and following […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
Down at hackspace today jake and I had a go at taking the eMac to bits. Jake is a bit of a cos play geek 🙂 This is the old eMac that is being turned into the helmet for his costume. I will ask jake for a picture / details […]
Today I am sat with Nathaniel, working out how to get parts for my Tantillusup and running, I have downloaded the Mac pre compiled copy of kliment /Printrun, from koti.kapsi.fi/~kliment/printrun/, (also needed Slicer for Mac). With both of these installed, when trying to load Nautilus Gears as a test, I […]
Following on from Part One, I have come across a number of ways of changing the focus ring via a servo, and if I was to use a Telephoto (Zoom) Lense on an SLR (Single Lens Reflex) Camera The Focal Length as well: Shoulder Rig Geared Follow Focus labeled lensgear-set […]
I have got the first parts of my Tantillus 3D printer, I got the outside parts laser cut by Sham Glam (1st post). Here is the unboxing photos, these were taken at Swindon Hack Space, at the Swindon Museum of Computing: Just need to order some printed parts, and get the […]
Instructables “21 Projects Guaranteed to Keep Your Kids Occupied This Weekend” is a free Kindle book, that I picked up to have a read of; there are some cool projects in it that would be worth a look at doing with the Cub Scouts 🙂 21 Projects Guaranteed to Keep […]
[toc]I have been looking around the internet for more ideas on Chording keyboards; and have come across more examples that I can use to refine my plan: The AgendA The AgendA is a British-designed organiser from the mid-80s. Its most striking feature is the microwriter keyboard. As if to encourage the use […]
