Following on from my previous Makevember posts… This is another virtual post, I built the Wind Turbine Hub as designed by Daniel Davis, one of the changes I would like to make, is the methord of making the blades. It looks like Daniel has a background in Mechanical Engineering, and […]

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 […]
Following on from my Makevember post yesterday, where I tried to make turbine blades, and Failed… I fed 6050 from SG6050 into Fusion 360 and this is what it gave me: SG6050 profile To check it wasnt it that was broken, I ran the script with the defult value of […]
I missed a Makevember post yesterday, and the one for today is going to be quite virtual again… Last time I did a post on K-9’s Back it was to work out how to read the buttons, and to do a first draft of the CADing up for the 3D […]
I have been a bit lax on my Makevember posts; these were just quick prints I lobbed on the 3D Printer: bathtub boat (visual benchy) Duplo train joint The Duplo Train Joints are for MiniBoyGeek, the other part will appear once I have printed the rest of it.
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 […]
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, […]
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:
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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, […]
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 […]
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.
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 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 […]
I found the ‘Picktor’ Pick and Place head for retrofitting on a 3D printer on Thingiverse (GitHub) As designed it uses a Nema 17 stepper motor, however I suspect that will be too big for my design. I got 3 x Nema 14 stepper motors from an old RepRap Huxley, […]
This is version one of a set of Left-hand Switches made for MiniBoyGeek’s Duplo Railway Yes there is already a version two waiting to print, with additional check rails and re-designed mechanism: You can find it on ThingiVerse here
If you do any amount of design with 3D printers, sooner or later you will find your self using bearings between two bits to help them move; normally you will reach for a “skateboard bearing” or a 608ZZ, however if you need a size that is not a 608ZZ the […]
On Saturday Tamarisk, MiniBoyGeek, Thinkl33t and I went to The MAD Museum in Stoke-on-Trent with Emily and Glen. We also found a nice little vegan coffee shop called Plantarium. Emily made Tamarisk and I a Flappity Bat for Christmas: Go look at her shop!
Since I got Pycom working on my Mac, I can now update the firmware on my expansion board, the DFU updater is available in Brew, which we should have installed in the last post. From the Updating Firmware page we can download the correct firmware file; I have the Expansion […]
