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. #electronics
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 🥳
A couple of weeks ago I finished a beast of a project.
The interactive installation (titled InStability) is an artistic endeavor to demonstrate how seismic stations in Iceland detect earthquakes.
Visitors are invited to touch the map, triggering "earthquakes", and observe how LEDs, representing seismic and GPS stations, light up as the seismic waves propagate across Reykjanes peninsula.
#Fake operational transconductance amplifiers I bought on #EBay over 6 years ago. Date code doesn't make sense given that Intersil discontinued the #CA3080 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. #electronics#opamp
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 #synthesiser prototyping. #electronics
Next part of my dad's HiFi is trying to understand his home built amp; it needs a bit of a front clean but was working OK. It's dated 1977, but has obviously been tinkered with over time - the power transistors on the back are dated from early 70's before I was born, but then there's a little preamp in there from mid-90's; so I need to figure it out. #electronics
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
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
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.
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. #diy#electronics#recycling
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.
