Do you have a assembly or a interesting device?
Please show it here!
Whether it is a finished audio amplifier or just "scattered" wire on a PCB test.

 

Are you familiar with the "Completed Projects" area of this site? Plenty of pictures in there.

 

I just hoped maybe someone wants to just put pictures without to public project.
I have no pictures of my old projects anymore.

 

I have several pictures of my completed projrct The most interesting one for mwsd gluued with super glue, Does yhe terms dead bug style prototyping or Manhatten style prototyping ring any bells?

 

Here's my precision temperature controller from this thread.

 

Seismology (studying earthquakes) is my main interest and I build seismographic instruments from scratch.

This photo is just the drum recorder which has three pens that trace ground motion in three axis on sheets of rotating chart paper. The ground motion sensors, telemetry system, and the amplifiers are not shown. However, I will post them later.

 

This might be something @Little Ghostman migh be interested in I belief he was looking for a PIC based temp controller for a chicken egg incubator.

 

Congratulations on your results!!

How did you make that PCB?
Did you solder SMD components with your hand?

I know the seismograph principle. Earth Structure, Waves P, S, R and L and those that derive from them.

Which PIC is that? PIC18F26K22?
Fun to see you are using the metric system for scale and not the imperial. Or are you...?

24k22. Imperial.

 

How did you make that PCB?

I sent the gerbers off to Advanced Circuits.

Did you solder SMD components with your hand?

Yes. As my age accelerates past 100, I find I need a microscope these days for the small parts.

 

This is a 4-layer PCB I was involved in designing many years ago. It has 64 channels on a 5.4" by 2.7" (137mm by 69mm) board.
Due to limited board space, the PCB layout guy had to put the diodes partly under the transistors. When I commented that he hadn't used very many vias, he replied: "There are 16 of them. That is all I had room for!".
Note: There are 64 transistors, 64 diodes, 8 10-pin SIP's, 8 16-pin DIPs, a 50-pin connector, 2 40-pin connectors and over 30 miscellaneous parts. The 50-pin connector is not installed. I would be in the empty holes at the front.

 

Now I have to realize a PCB too. Use print and toner transfer foil. Or is better to ordering at a specialized firm?

Define "better".

 

Why is this my strange response? I wanted to bring this discussion back to the "forefront". That's because I like to see various devices from users.

I dream of selling a small device. But PCB gets expensive if I do it in China (PCB way).
Transportation costs a lot.

I could do it with the ironing machine......

If that were a cost effective method of PCB manufacturing, wouldn't everyone be doing it that way?

 

Making PCB with toner transfer is a lot of manual labor. A bit less labor with UV led and photoresist. With the latter, you can re-use the graphic. But then again, you need a developer.

 

I want to show you my program in Assembler x86:
