Its sad when someone tries their best to solve problems for them selves and get scammed by some lowlife. This customer of mine had a small issue with her log on to get her Yahoo Mail, just a bit of a password problem. So she went onto the yahoo website, and saw what she thought…

New Home Computer
It’s not often I splash out on a new computer, normally my computers are Frankenstein machines rescued and upgraded using stuff abandoned by customers. However, the last computer I bought for home, about 10 years ago, was starting to show its age. It is an Acer L3600, with a dual core E4600 processor, originally with…
Ebikes – DBMS issues with counterfeit parts
The DBMS worked fine for 50 or 60 km, but the behaviour of the various components – batteries, motor and controller and DBMS started to get erratic, and it started to get difficult to tell what was going wrong. I slowly removed items until I was back to a normal set up on both bikes,…
Ebikes – dual battery managment system more riding.
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. I realised…
EBikes – Dual Battery Management System
The only commercial developer of dual battery electric bikes I have seen to date is Bosch, who do an optional Dual Battery kit, which one or two manufacturers have taken up. Being proprietary technology, there is not a lot out there about it. The only two things I can glean are: 1. The real technology…
Anatomy of a scam
This post may take a few days, so keep coming back! Some background first. I repair computers, and a few customers (3 or 4) have been hit by the “Windows Corporation” scam, where someone thief rings up with a very Indian accent, but with a very English name, claiming to be from the Windows Corporation,…
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…
