My Chinese knock-off USB wall chargers say “Designed by in California” on the back. Classic.
I got myself a new iPhone 6s this week on eBay for forty bucks. Gonna use it as an extra small screen on my bench. The features to price ratio is insane. When I was a kid I couldn’t even imagine a pocket computer like this, let alone getting one for forty bucks.
Here’s a happy snap of me getting the new iPhone setup:
Some articles about USB on Hackaday recently:
This week I discovered Jan Axelson. She’s a tech writer and her website is here: http://janaxelson.com/.
I have ordered four of her books:
I organized my USB cables drawer. Left is USB 2.0, right is USB 3.0. Front is Mini-B and iPhone cables (including Lightening cables), middle is Micro-B (5-pin and 10-pin) and Type-A, back is Type-B. Conspicuously absent are Type-C which are filed in a different drawer. Also front-right are adapters, switches, hubs, and there’s even a USB light in there.
As mentioned on EEVblog 1619 – Mailbag: Featuring Don McKenzie the ADUSBCIM USB CABLE CHECKER 2. Gonna put that one on my shopping list.
Happy New Year! Best wishes to all my friends for 2024.
I have this weird problem with my new studio computer ‘verve‘. When I press the power button, it doesn’t turn on. It does have 15 USB cables plugged into it, and quite a number of those are powered, which seems to affect the system.
The power for most of the devices on my bench goes through a PowerShield Defender 1600VA UPS battery, and then through an Arlec PB91 Residual Current Device (RCD).
The RCD has a test feature so you can press the button on the RCD and it will trip the safety which will disconnect the power. If I do this most of the equipment on my bench will turn off (but, importantly, not my workstation ‘verve’) including all the powered USB devices which are interfering with my computer.
After I trip the RCD I can power on my computer, and then once it’s powered on I can reset the RCD and bench power is restored. It’s a bit fiddly but at least it works!
There’s nothing like being organized! There’s nothing like having the right equipment!
By my count I have 25 USB ports on the back of ‘verve‘ and I’m already planning to use 15.
I have the first draft of the USB cabling for ‘verve’.
Got myself a USB powered UV light. It came with a few tubes of solder mask:
I’m gonna keep this in my booth where it will be used. Don’t want to use it anywhere near where I keep my UV solder mask because I don’t want to accidentally cure it!
