An update on the autonomous self driving Uber Volvo XC-90 involved in the pedestrian fatality.
It is being reported that Uber disabled the Intel Mobileye collision avoidance sensor that is factory fitted in Volvo XC90.
Intel have ran the dashcam footage of the accident through the Mobileye system and said that even with the dark footage it would have detected the pedestrian a second before the incident.
Are analog multimeters still of any practical value compared to digital?
Only Dave can ponder that question for a half hour video…
A self driving autonomous Uber car killed a pedestrian in Tempe Arizona. How did this happen?
It basically shouldn’t have.
TLDR; It looks as though the LIDAR and/or RADAR system failed to detect the pedestrian until fairly ideal practical circumstances.
A look at the newly released camera footage of the accident, the location, and the car LIDAR, RADAR, and camera sensor suites available to prevent such an accident.

A further clarification to the previous video on the Hakko FX-888D vs the JBC direct heat CD-2B soldering station. And the differences between applied power, tip design, sensor design, control loop design, and power delivery to a ground plane.
Power measurements and DaveCAD explanations.
What are the differences between the “old” style soldering iron tips like used on the low cost Hakko and Weller et.al low cost irons, and the more expensive integrated tip type?
An apples to oranges comparison of the Hakko FX-888D and the JBC CD-2B stations.

Repairing the Data IO universal programmer.
Will it be a happy ending?
Marty! This is the big one, the one I’ve been waiting for all my life!
Teardown of the classic Data IO Unisite Universal Programmer from the 1980’s, with a typical configuration selling for $35,000
It stayed in production for over 20 years.

Just the product the world has been waiting for!
A $7000 Internet of Things intelligent umbrella with GPS, WiFi, Bluetooth, solar power, 360 camera, and an app.
Someone liked the idea so much they invested $2M in seed funding.
Throw in a bunch of patents and a dodgy Wikipedia page from an Indian marketing company and we have a winner!
WIRED are looking for a new tech journalist, and this triggered something in Dave he just has to rant about. What about skepticism in tech journalism?
