I watched the Trump Speech and I must say.... It just showed that the Childish Democrats "stood" for the Pathetic Losers they are.... Hope voters remember this and NEVER vote Blue Again..... As to the Signing Meeting with Zelensky..... Zelensky had 3 years to learn how to speak to Brain Dead...

The Music and Images are good... IMO:ROFLMAO: Jerry

Yeah... His Cybertruck is God Awful Ugly.... and yes he seems a bit out of place in large crowds. I still think he is a Genius for all the things he does and has accomplished previous to him being Appointed to run DOGE. He and his young team have already found Billions of Wasted Tax Dollars $$...

Too bad we can't see the Trailer full of Batteries to power it...:whistle: Jerry

I don't believe you are still at it.... Boo... Hoo... Stop Whining already Paul.... Trump Won... Word Salad Cackling Kammy LOST by a Landslide... You really need to Suck it up and buy some tissues....😢 Nothing you can do or say will change the Fact that Trump is President for another 4 Years. Jerry

Got it.... -The Original Camera worked on 7.8VDC -The Original Camera is DEAD -You want to use an Off the Shelf 12VDC Camera to replace it. Try a Step Up Boost Converter like this...

If your Vehicle is only giving you 7.8VDC you have a problem with your Vehicle's Battery. It should be at least 12.8VDC fully Charged. Where are you Testing/Getting the 7.8VDC ?? What is the Vehicle's Voltage at the Battery Terminals ?? Do you have a link to the Camera ? Jerry

What current does the Camera Require ? BTW If you require less than 12VDC then you will need a Buck Converter. Jerry

Yeah that Canada Post strike put a Kibosh on our annual LPF Black Friday and Cyber Monday Sales... Haven't heard any complaints by customers of the Tarrifs if they are in effect. Jerry

I've been looking into spectrometers for a while. Here's a link to a Google Search.. https://www.youtube.com/results?search_query=spectrometer+diy I found this one to be quite interesting and seems to cost less than $50 USD. Jerry

Nothing Silly about it.... Been there done that. Good learning Laser Project. There are many circuits to do that out there. Google is your friend.... The problems lie in how you set it up. Also keep in mind Snow/Rain/Fog/Air Pollution will effect total detectable range to begin with. Another...

The Coherent Fieldmax is a great LPM. The Optical Sensor supplied is not. It's only good to 30mW and only in the Visible Spectrum. Here's a spec sheet. https://content.coherent.com/pdf/op-2_lm-2_opticalsensors_datasheet.pdf Problem is the Calibration of a Used Lab LPM. They are VERY expensive...
