Voltlog #248 – Atorch Q7 USB Meter/Load With QI Wireless Charging

So this load is built with 3 active pcb’s as well as a fourth passive one as a front panel. They are joined with these brass standoffs and I think the standoffs act as circuit paths as well because I see no wires between the different levels. In order to get the alignment right during assembly the designer of these pcbs, made these corners rounded while these ones are diagonally cut and you can see these features along an entire side. This is a neat solution overall because it saves cost and as long as the screws are tight these should provide adequate connection.

Voltlog #247 – InTheMail

Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. We’re going to start with this small module, at first when I ordered it I didn’t fully understood what it does but now after doing a bit of research for this mailbag it seems this is an immobiliser emulator for the VAG group. So am immobiliser is a security component of your car that will not let the ECU start the engine unless a certain key or token is present. And there might be valid reasons why you might need this emulator, for example if the immobiliser is broken, you can supposably cancel it and start the engine with this emulator or if you exchange the motor/ecu combo once again it might not be possible to use the old immobiliser and so an emulator will help.

It talks over a K-line interface which is something specific to the automotive domain but it’s basically a form of serial interface. At first I thought this was going to emulate some kind of can bus and I was planning to play with it by scanning the bus but now I realize this is useless for me.

Voltlog #226 – InTheMail

Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. We’re gonna start with this set of tweezers from Vetus. A few months ago I was considering buying some more expensive electronics tweezers but the good ones are really expensive when you include shipping as well so in the end I decided to give these a try. I’ve had Vetus tweezers in the past and some were good some were bad. This time I asked multiple sellers on Aliexpress if the tweezers are original Vetus or not, some responded and promised their goods are original. Coincidentally or not those who said their products are original also had higher prices. In my experience with suppliers, they never lie about the origins of a product if you directly ask them so I tend to believe that what I have here are genuine Vetus tweezers

 

 

Voltlog #194 – Gift Ideas For Makers – Christmas 2018

Welcome to a new voltlog, so december is coming up and some of you might be thinking what gifts you could offer to your loved ones. I thought I’d share my ideas and what I would like to receive as a maker or hobbyist. The criteria for choosing these items were mainly to be decent quality products, at affordable prices and be things that a maker would later use in his projects. As usual you will find links in the description on the video on youtube to places where you can order these online.

So these are my recommendations for you, I would for example be happy to receive any of the above and that’s how I made this list, thinking about what I would be happy to receive or what would be really useful and fund at the same time for a maker. Let me know in the comments below if the list helped you in any way to choose the right gift for someone. Thank you for watching!
