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 […]
Using a LED and a 560 Ω in most breadboard projects means that you end up with four pins connected for two components, soldering them up like this makes them much easer to handle.
In the UK if you want to place some thing on the market you need to ensure that it has a CE mark and has a DoC (Declaration of Conformity), there are a number of things that need to be done. Looking through the list, we have CE, RoHS, WEEE, […]
…Are negligible! Following on from my last post; that seems to have got a wide readership, I got sent this link and asked to review it; the title of the article is “Scientists Appeal that 5G Wireless is as Hazardous as Asbestos”, which I think we can all agree contains […]
…and other lies adults who should know better spread! On Facebook a friend of mine has joined the crazy Electrosmog people; I was first made aware of it when she posted outrage at an article in a small paper with the headline “Glastonbury Festival 2019 to be first ever music […]
We went to Hack Green Secret Nuclear Bunker, to be fair it is badly named… its got far too well signposted; the entire place is a maze or exhibit rooms, and displays showing an over view of life during its time as a bunker.
Following on from last week where we drove a motor in one direction with the help of a simple amplifier, this week we are going to have a go at driving a servo. Those of you who read older posts in my blog will know I have done this before […]
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 have started putting these on Github so you can also follow along. In Weeks 2, and 3 we were driving LEDs directly from the Arduino, While the Arduino can drive a LED directly from a pin, if you want to power something that draws more power like a motor, […]
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 […]
Following on from week 1 and week 2, we will be continuing our way through Oomlout’s Arduino Guide, at this point however we hit a snag with using iCircuit. Annoyingly iCircuit is unable to deal with arrays. An array is a cunning way of holding multiple variables inside a single […]
In Week 2 we made a single LED blink using an Arduino, now about 99.9% of the time this would be overkill (the 0.1% of the time is when you are learning); actually tell a lie, There is a VERY good reason to flash a LED with a micro, but […]
Following on from Week 1 and talking about faking it with an Arduino, we will use UnoArduSim.exe and iCircuit to model the first few circuits from the Oomlout.com’s “Experimenter’s Guide for Arduino” (Full kit was available from here). Oomlout have made the ARDX-circuit-sheets available separately to their guide PDF. Circuit […]
If you want to learn Arduino programming, but don’t always have access to a box of physical hardware, there are a number of Arduino Simulators available, however one of the best ones I have found to use, is also free. UnoArduSim Arduino is a great platform, but If you’re trying […]
After the print yesterday, I wanted to know what the 100% sized eyes would look like. Having also thought a bit more; I can think of a better way of constructing the head, so that is back to CAD for a re-design. The 100% eyes seem to have printed only […]
A while back, I went on a Geek Walk to Bletchley Park, This time Tamarisk’s Uni Computing Society went for a Social. We didn’t catch up with them, but we went as a group anyway 🙂 Last time I thought it would be cool to make an Enigma Machine, this […]
Many moons ago, before Seven Fields was built on, so I assume 1990s, My mum, Debbie McGaw took some photos of the area showing what it looked like at the time. These photos were for many years on show at Emmanuel URC Haydon Wick in Swindon. At some point the […]
On Boxing day, Tamarisk, MiniBoyGeek, and Granny went for a look round Warwick Castle, We also saw the Mill and Hydroelectricity plant on the river Avon
In traditional fashion, A challenge I am likely to fail… however anything that risks me reading more books than normal… So lets try Linz’s The Bookworm’s 2019 reading challenge, this 60 book challenge can be done in parallel with attempt ¿Four? of the 100+ Reading Challenge. Level 1: Book of […]
A while ago I picked up these buttons for my Dr Who’s K-9 robot from AliExpress, Hobby Components have similar available online, The ones I purchased are SPDT with a 24 V DC incandescent bulb in them, regardless of the button colour they are all illuminated with a white incandescent […]
As in my Q-Blade Post 1. I made reference to both HAWT (Horizontal Axis Wind Turbine) and VAWT (Vertical Axis Wind Turbines), A standard VAWT design has been covered by the Ultimaker Blog: There are several other designs that are more novel. One of these novel approaches is the O-Wind, […]
After my previous attempts at cadding up air foils, that can be found here and here for #Makevember, I came across QBlade; According to Wikipedia: QBlade is an open source wind turbine calculation software, distributed under the GNU General Public License. The software is seamlessly integrated into XFOIL, an airfoil […]
I have been back in Fusion 360 designing parts for my wind turbine: These are parts of the hub, they are the bearings 3D printed to be the size of F 6902-2RS (15x28x7 mm) bearings that are commercially available, the printer settings have been edited slightly, so I still have […]
Another boat: I was trying to dial in a 3D printer, the blobs on the hull seem to be caused by buffer under-runs from the Raspberry Pi. In the last Makevember post, there were some strange shaped Duplo links, here they are in use:
With MiniBoyGeek’s help I made a Crocodile: Perhaps it should be said that MiniBoyGeek had my help with this Makevember post.
Libvirt has finaly been fixed to work on OS X, LibVirt Manager is what I use to manage the Virtual machines on Sandraudiga. libvirt is an open-source API, daemon and management tool for managing platform virtualization. It can be used to manage KVM, Xen, VMware ESXi, QEMU and other virtualization […]
