It is taking forever -_-

Got a lot of exciting stuff to make videos about, but the latest project is just not ending ...

Some progress with the pressure sensor matrix

This 24x24 matrix on foil is supposed to be the last experiment before committing all the expensive materials to the full size 180x60 yoga-mat-compatible version.

Not looking forward to working with...

I am supposed to do this for a 60 x 180 cm mat

And I am dreading it (:

The copper tape is very difficult to put down perfectly. One tiny mistake causes...

Got a real firmware update through

But after that it still didn't work :((

Anyone wanting to file a patent?

Temporary, solvent-free, metallic nail polish foil. Also Available in silver. (aka copper tape, aluminium tape)

I have found the worst thing you can attach to an 18650 battery pack

Few will see what a big deal this is

But since you are here, I guess likelihood of understanding is at its maximum :)

This is the memory chip from the  damned  Zoom H4n audio recorder I have been working on for weeks.

Last few parts for another big project

300 $ worth of copper sticky tape in that bag ... that'll be fun ... I hope

New toy

This is an accelerometer-based screwdriver from the manufacturer of the infamous TS100 soldering iron.

Very good quality, but I am not sure if there is any market share left between manual screwdriv...

5V Arduino Mega running stably on 4.3V

... with an artificially bad USB cable (10 Ohm). I am trying to get closer to the flash chips max input high voltage of 3.9V without including roughly 48 level shifters ...

This better be working ...

Product videos?

I am being approached by many companies at the moment. Everybody wants their products in my videos. What do you think about it?

My thoughts: I am trying to make the product videos 'on the side' when...

I am very determined to get into this bricked Zoom H4n

Bought a surprise for the dogs, they didn't like it.

New laser machine

PID Toaster

It can't follow a proper reflow profile but I am sure it would do fine for a quick batch of boards. Or for heating etching solution to 50°C ... or aging components?

Another synthesizer module

I still need one for the empty slot in the Elektor Formant, but again, this seems a little boring, don't you think?

Time for the dogs

The Chinese sure like my videos

Now they are using International DHL Express to get stuff to me quicker. Hope I can keep up :)

Random rectifier regulator replacement

Keithley 164 Nixie Tube Multimeter Repair

But something is still not right (apart from the stuck 8)

Replicated an ancient nixie tube driver

For the Keithley 164

Hope this one will expose circuit board

No bumpy linear rails, no slow, proprietary motor controller ... I think it will :)

Bricked firmware on this beauty

Would be a drastic increase in audio quality if I managed to repair it. But I think I would have to do a lot of RE on a .bin firmware file and figure out exactly what to write where on a large flash c...

Something I haven't published

But I didn't sign an NDA either so here we go ...

Lasercubs will be back soon! :)

Gonna need a surgical robot for this

Well it is better than before ...

but has a dead display now :(
