Things I've Built

HW: USB powered water sensor for office green lily

To get constant moisture level, I've put together an USB powered whatstone bridge with uA-meter as display. Moisture is measured with two wires and an npn transistor. Other side of bridge is a trimpot for 0adj. 40uA makes my green lily happy.

LED lights for whole flat

same principle as "LED torchiere", but built low-cost with steel cable spanned across the room, crocodile clips, massive copper wire. Approx. 3 Watt per square meter for a daytime-like light impression plus super low electricity bill.

Lab #02 (Lab #01 relocated and expanded): electronics

most of my electronics stuff happening here. power supplies, isolation transformer, signal generators, multimeters, scopes, microscope for smd work,... there is an additional storage room with shelves/boxes for projects and less used parts

~500l/min air compressor upgrade and repair: works.

poor litte air compressor fell off a forklift... new motor, belt and pulley, motor control (all smashed), oil exchange, built mechanical motor adapter, belt protection cage, sandblasting cabin...

Mercedes Benz L319 restauration (ongoing...)

never ending story ;) Lots of (sheet) metal work to be done, starter does not work yet...

SW: "simple 3D scanner" (Jugend Forscht) volume intersection stuff based on point cloulds (re)constructed from reverse projected light path from webcam images. C++. high school project info/math.

SW: Unitrent UT61E linux SW for USB cable

Had to interface my two UT61E with my Linux box but no SW was available/working due to kernel usb stack changes. in the meantime there should be a kernel module for that usb-rs232 converter.

SW/HW: exotic IBM/SGI "dials" connect to modern computer

no documentation was available

HW: Röwac KGL161 MIG/MAG welder repair

control board was completely broken (no protection fuse + short circuit...), most switch contacts bad/highZ, no documentation was available (=reverse engineered the whole thing)

HW: VGA ambilight clone 1channel 1. Take voltage of r,g,b VGA channels 2. voltage-to-current opamp circuit 3. drive led stip 4. ??? 5. profit

HW/electronics: LED torchiere laptop power supply, led modules (step-down current regulated), CNC wood mounting bracket

HW/electronics: Ultimative Laptop Suitcase

based on aluminium Rimowa Service Suitcase from 1980s/1990s including: mobile phone charger, battery charger, flatbed scanner, card reader, 2nd ethernet port, tons of usb ports, dj gooseneck lamp, bluetooth, gps, mains or car powered, ...

Hi rawe,
Thanks for the skull! I'm going to have a look at your impressive list of projects here, very interesting.

Hello Rawe, I would love to see more about the Mercedes Benz L319 restoration. Please make it a project and add logs and photos. DIY modded mobile homes and small spaces are great. Like your other lighting project too. Thanks for sharing.

Thanks for the feedback :) I would love to see more about that, too... did not do anything on the car itself since last fall due to lack of time/personal reasons. As this is a thing we started to learn along, lots of things were done in addition, like buying a welder for way too much money, figuring out is was crap (only two current settings, live all times, motor powered by welding transformer which leads to stuttering), pimping it (seperate transformer for motor, contactor for the welding transformer,... - need to upload that as project, too), buying a professional-grade but broken welder that has seen quite a few race cars (the Roewac one) for nearly half the price of the crap one, repairing that, figuring out we need a bigger air compressor to do small-scale sand blasting.... etc etc.

I try to get my welding and sheet metal skills to a reasonable level before doing serious metal work on the car to not damage anything (more than it is already by rust), but that needs practice = time.

There is a slightly outdated project log in German over here: , if I update it, I'll plan to put it on, too, if I get time for that.

For the next 3 days, it is planned to get the rear axle out and to start reworking the parts.

Thank you for the follow. I also have saved many things from the dumpster. Crazy what people throw away sometimes. Hack on fellow warranty voider! Also please consider voting for my Ma'Tok Staff project.

Thanks for the feedback :) Dumping things and buying them new because they are relatively cheap vs. repair cost (plus people just want new and trendy things) - thats the downside of todays industrial mass production. But at least there are really interesting things to play around cheaply.

  Are you sure? yes | no
