This is following on from my previous post introducing the Protek 608 multimeter and my software project. In this post I detail the communications hardware, an important consideration for future development. The Protek 608 uses an RS-232 connection to allow for interfacing with a PC. This is a very common connection that most DMMs used. […]
The Protek 608 is a 5000 count digital multimeter made by Hung Chang, who have since changed their name to GS Instruments. I’ve owned one of these since about 2009. This multimeter is now discontinued and no longer available new, although they occasionally show up on the second-hand market from forums and eBay. This DMM […]
I’ve used an infrared thermometer at work for a while now and find it a great tool in many situations. However I felt that there is still room for improvement. I’d like to see better sampling modes, live trend graph, and even USB data logging. There are some tools that have some of these features, […]
After posting my project I had a number of questions online. I thought this is a good opportunity to update the blog to share more information on this project. GUI concepts I’ve made some more progress on the software side of things, mostly just playing around with the graphics display. The Nokia 3310 LCD screen […]
This is a project I started about a week or so ago and have been working on when I find time after work. It’s a GPS and compass that temporarily uses an Arduino Nano micro-controller, Nokia 3310 screen, EM-406A SiRF III GPS receiver, and a simple (non-tilt compensated) magnetometer for compass heading. It’s obviously in […]
My video review of the cheap Aoyue 937+ solder station:
Last night was a bit wild. I remember getting home sometime in the early hours and stumbling from the car (wife was driving) to the shower to soak away the drinking. By the time I realised that I was still fully clothed and had my wallet and week old iPhone 4 in my pockets, they […]
The lowboy arcade cabinet design, as the name suggests, is a relatively small cabinet that was common in Australia during the 90s. I remember these being more popular in corner stores than video game arcades. They were a cheap and compact alternative to the standard larger cabinets and could easily be converted to play different […]
