Are you working with an KiCad or Fritzing and want to support them? Select the Development Contribution option during checkout. This will add a €2 charge to your order, we will double this and transfer it to the developer of the tool you used.

Finally got myself one. It's been a long time coming but really wanted to get some accurate data on how good/bad my board's power consumption is.

We at ZERO GmbH have completed our first prototype to display our own content in vehicle on-board systems. The touch function of the display can also be used to write ZERO in the most beautiful font ✍️ 😅

So...why all this? With the help of our AMPS platform, our customer can easily show new designs or functions in a vehicle and bring them to life - without having to access the series components directly.

And "easily" really means "easily":
Connect computer viaHDMI => switch on via button or CAN => be happy 🥳

Person writing "ZERO" on a vehicle infotainment touchscreen inside Microsoft Paint. You can see that MS Paint has been displayed in the vehicle by using our "HDMI to car infotainment" product.

That one time 11 years ago when I was trying to build my own 8-bit computer from scratch.

operational transconductance amplifiers I bought on over 6 years ago. Date code doesn't make sense given that Intersil discontinued the over a decade ago. The real chip should have a diode across pins 4 and 5. Only one chip seems to have it -- but it is reversed. The rest have resistors between pins 1 and 4, and between 4 and 5, consistent with an op amp that provides offset null pins. Pin 8 also seems to be connected. Both 1 and 8 should be NC.

In my dreams, there exists something that is as simple to write code for as the Arduino, but it's as fast as the latest AMD or Intel chips. This would greatly help me with the prototyping.

The DC rails on this failed switching power supply from a wall wort AC adapter, were shorted together. It could be one of 4 components: 2 electrolytic capacitors, a surfacemount ceramic capacitor, or a surfacemount Schottky diode. Started desoldering each one and testing for the short. It cleared when the Schottky diode (SK26) was removed

I don't think I have a high current replacement diode in this form factor.

I do have a 1N5822 Schottky

Comparing datasheets
SK26 60V 2A
1N5822 40V 3A

The voltages on this side of the switch mode power supply are not expected to be much higher than 12V DC. This wall wort is rated at 600mA 7.2VA. The electrolytic caps are only rated up to 16V

Will it work?

Curious about our ArtNet based light control system?

We've created a web GUI that enables easy access to various typical vehicle lighting scenarios. The operator gets instant feedback about the currently activated scenario.

Our layering concept allows prioritizing lighting animations and stacking them on top of each other.

By the way: Animations are provided as CSV files. You're free in choosing the tool to generate these.

Video shows a split screen: Left side displays a web GUI in blue color. Various buttons in a row. Each button has a light function assigned to it: "Welcome", "Goodbye", "Warning light", "Brake", ... Right side shows a light strip and a light controller that translates the button pressed into light animations on the stripe.

Does anyone want to have some of those smart watches to recycle? I have hundreds more of the color watches and about a few thousand of ones with a black and white round lcd (dot matrix) and batteries in unknown states. They are all broken (amazon returns) and the company that did the backend is bust since corona hit, so getting them to run again is not possible. If there is private interest i think i can convince my boss to give them to you for shipping.

https://cemsim.com/ is a really cool real-time 2D electromagnetic field simulator.

It's open-source and implemented with GLSL shaders. The simulation kernel is right here: https://github.com/RobinKa/maxwell-simulation/blob/master/src/em/kernels/simulation.ts

A real-time 2D electromagnetic field simulation of the double-slit experiment.

Long shot but my DIY analogue chorus pedal (clone of the Julia) makes clicking sounds in time with the chorus rate. I am pretty sure it originates in the TL072 op-amp used for oscillation. What I can’t work out is how to stop it. Others have built the same kit and not had the same issue. Power is clean (battery), have tried a different chip. Going slightly mad with it.

Note to self:

Do not try to pull more than the rated current from a cheap Chinese Solar Charge controller's USB output.

Even if it's just 60mA...

Does anyone know what that chip could be - I'm having trouble finding anything...
