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, […]
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 […]
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, […]
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 […]
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 […]
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 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 […]
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.
At work we have a Narda probe for measuring EMF. We wanted to read the value of the three orthogonal coils into an oscilloscope. And of course by not removing the ferrit of shame its too short.
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 […]
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 […]
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 […]
In the UK there is a monthly free PDF magazine called Hackspace. Back in Issue 4 they featured a Project by Archie Roques where he made an IoT Kettle… Here is the Pages from the magazine: The relay board chosen for switching the mains in this project is the ‘Spark […]
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 […]
I came accross Makevember randomly from This blog. The 2018 Manifesto: Every day in November make a thing – if you can’t do it every day then do what you can. Push yourself to make daily, with less procrastination and quickly. Limit your time, always share the results. Be kind […]
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 […]
Bob found these ESP8266 based Wi-Fi Relays from china, the “Sonoff – WiFi Wireless Smart Switch For MQTT COAP Smart Home” and being that he is is kind of a geek he bought some, now in typical China fashion the difference between 3 and 5 was not all that much, so […]
A while ago I looked at the HLK-PM01, and amazingly it turned into a very well read post… (do not even touch the cheaper crap!) with a lot of people asking how to make it work properly. I also got an email from Tom at smart-sense.hr saying that he had […]
Every so often we see on line storeys of fake chargers burning down houses, and electric shocks. Normally these chargers are refereed to as ‘Apple’ or ‘iPhone’ chargers, however that is just because the small triangle chargers (in a variety of colours) are so prevalent. An official Apple 5W USB […]
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 […]
I have been playing about with Fusion 360, one of thrings you will need to include before very long is a fixing, even if you can 3D print everything in your design at some point you will want to stick two parts together at which point you will need a […]
I have been playing with Fusion 360 again… and as part of that I have been finding cunning tricks that I am thankful that I now know. Since I think I have a blog or something, I shall share those I find to be useful. And for this I shall […]
Everybody loves a train set and LEGO Duplo tracks make it very easy to build your own set, I have watched YouTube videos of peoples Lego Train Sets, and thought that they were cool however if you look at the price of Lego City Train sets, prepare to cry even […]
Recently there have been people claiming that they can steal money from your pocket (up to £30) by skimming your credit or debit card info using a EPOS (Electronic Point of Sale) or PED (Pin Entry Device). It said thieves could exploit a security flaw to steal key data from […]
I picked up a Hantek 6022BE USB Oscilloscope as sometimes its useful to have something more than just a multimeter for seeing what a circuit is doing. While the specification makes it more of a toy than a real instrument, however what can you expect for £46.00? The Hantek 6022BE […]
