Two more days of testing, a week apart, building on the numbers from day one. Total kilometres over the three days 66.4 and total time on road 3h22m, giving an average of speed of 20kph or thereabouts. The bike was definitely starting to get sluggish towards the end, and the gauge on the bike was…

Ebikes – dual battery management system – first rides
I have waterproofed both the DBMS and the power meter, so am feeling a bit happier about going out for a ride or two. I did my first ride just after I finished the basic unit, but it was all a bit short and hilly to get a grip on what was happening. I had…
Ebikes – dual battery management system – build and install
Build After a few months of designing, prototyping and waiting for all the components to arrive, I finally had enough to build a working, install-able prototype of my Dual Battery Management system. It is still a prototype, and like all prototypes is too big, too heavy and too expensive. I am not an electronic designer,…
Counterfeit Laptop Power Supplies
A few months ago, I supplied a Dell charger and battery for an older laptop. Because I wanted to get them at the same time, with a single postage charge, and the battery was quite difficult to find, when I found a site that had both available, namely adaptershop.co.nz, I ordered them both.

Onion Omega – next steps
I have made some serious changes to the PHP web page which servers up the door controls and web cam images, so I decided to finally get FTP access to the files on the Omega. The arrival of my second Omega made this even more relevant! Wirelessly access and edit the files on your Omega…
Business Directories – unsolicited entries
I seem to be getting a number of requests by phone and email to confirm details for an entry on yet another internet business directory. I fell for this as the start, adding myself to a couple of directories, at the time they were respectable and small business advisers advised “claiming” your listing. Since then,…
Yuba – display woes
After just a couple of hundred kilometres, the main display unit described below stopped working correctly. It bega with it occasionally not switching on first time, needing a repeat try, and this gradually got worse until it was taking 6 or 7 tries to get it switched on. Eventually it reached the point where it…
Garage Door Opener – a tinier computer project
Despite the issues with bricking the device and it recovering itself in a random state, I decided to go with what I had rather than risk bricking it again. This caused a few issues, but I can live with them. Below are the steps and some notes about how things went.In the picture below is…
