Simple USB Cable Tester

Steamhead, being a Maker Space, has a lot of USB cables. Some of these might be broken, or only have two power wires for charging something, or might be intermittent or broken wires. I was working on a Arduino Nano project and didn't know if it was the old Nano I have been carting around Asia for th...

Solder Practice Board

You can find many cheap and interesting SMD or Through-Hole soldering practice PCBs on-line. I thought I would have a go at making my own in KiCAD, with some Steamhead branding. It's a simple two transistor mono-stable blinky LED device and combines a few through-hole and simple SMD components. JLCP...

Chinese PCB Hot Plate

Been designing quite a few PCB's while staying at the Shenzhen Steamhead Maker Space. One bug bear is the lack of a PCB Reflow oven or a hot air gun. This was fixed by purchasing a small 400W Chinese PCB Hot Plate. This cost RMB170, or about A$36 and was donated to Steamhead. PCB-Hot-Plate_sml.jpg W...

Digital LED Candle

I have always wanted to make my own digital LED candle. Since I am currently in Shenzhen, China - the capital of the world for electronics, I thought it could make a quick simple project to do here. No real pre-project specs, just that it must have multiple LEDs and use side-lit fibre optical cable....

Re: WiFi LED Matrix Display

Now that I have a working LED display on WiFi, I have configured to be either an independent WiFi Access Point, or at a push of a button, it can connect to a previously configured network (Static IP, or DHCP IP). I was walking the Shenzhen HQB electronics markets the other day and came across an ESP...

Re: WiFi LED Matrix Display

The LED Display Arduino code and webpage have now been updated to display a SW Maker logo. Three seconds after you turn on the Display, the colourful SW Maker logo is displayed: swmakers-colour.jpg If you then attach your computer/mobile device onto the 'SWMakerDraw' LED Display Access Point, this w...

WiFi LED Matrix Display

While volunteering at the 2019 BSide cyber security conference: https://bsidesperth.com.au/, I came across a cute 16 x 16 LED Matrix display. This used an ESP8266 to host a WiFi access point to display a webpage that allowed you to draw patterns that could be submitted to be displayed onto the matri...

Re: Mobile Game Tracking Rig

The above rig was built around a RPi 2B computer board. I found that it would OCR a screen photo in about 5-6 seconds. Driving at the speed limit of 110km gives us around 9.8 seconds before we enter the next 300m cell. Not much time to react to any information that might have been gleaned from the O...

Re: Tracking a Website Block Post Comment Relationships

So, I have now collected and parsed a lot of 'The Conversation blogs and their comments. I thought it might be interesting to view a word-cloud of all the blog post tags, or categories that have been listed against each blog post. Blog posts can have anywhere from 0 (I think that was an error), 1 to...

Mobile Game Tracking Rig

A friend likes to play a mobile phone game (no names). One of the functions is to physically visit locations/cells to capture them These cells are around 300m in diameter, so there are lots of them around. Unfortunately as of August 2019, there is no method of viewing the places you have visited. Wh...

Re: E-Ink Data Display

With the electronics and programming out of the way, it was then time to design up and print a housing for the display. I wanted it to sit on my desk monitor, with gravity holding it in place. I also gave it the option of sitting on a flat surface, ie Desk. This is the Design Spark Mechanical design...

My wife wanted a device to hold a normal thread bobbin onto a Bernina bobbin. I opened Design Spark Mechanical and quickly whipped up a drawing for two different thread bobbins: Bernina-peg.3.jpg There are two different length spools and they both have different sized diameters, hence the need for t...
