Making a Lego Man in Autodesk fusion 360

Lego man

I have been working with Autodesk Fusion 360 to get knowledge about the program and to make a tutorial for a Coding Pirates class.
The tutorial is about learning the kids drawing in 3D and what is better than drawing something they all know and love.

I am in the process off making drawings and youtube videos for the tutorial. The first video is uploaded: Youtube video – Lego head in Autodesk Fusion 360

 

Learning the art of electronics

Finally got my copy of the book “Learning the art of electronics” it has been underway nearly 3 weeks but it is definitely worth waiting for.  And it is a must have companion for the AOE A.K.A. “The bible” when you are a novice like me.

Thank you David Jones – Eevblog.com for blogging about the “Art Of Electronics” last year when the third edition was published.

ESP-01 Programming adapter

This weekend i finalized my ESP-01 programming adapter board.

Protoboard for ESP-01 ProgrammingThe circuit is a little bit changed compared to the diagram posted earlier in the post “ESP-01 Module”

I added two terminals for connecting external 3,3V and GND. This change I made because I could not get the wifi function on the ESP-01 module to work, when the module was powered through the USB to TTL board.
On the left you see the board i made.

 

 

 

Protoboard for ESP-01 Programming with modules And here you see the board with the ESP-01 and USB-TTL modules connected.

I have not desided yet, but maybe I will add two terminals for wire connection to the GPIO0 and GPIO2.

 

 

ESP-01 programming circuit

The programming circuit is finished. And guess what! It works.

The buttons is from the left: Reset and Flash.
When uploading your Arduino sketch follow this procedure

  • Push and hold reset button
  • Push and hold flash button
  • Release the reset button
  • Release the flash button
  • The ESP modul is now in flash mode
  • Push the “upload” button in the Arduino IDE
  • First the sketch is compiled and afterwards it will start uploading.
  • Then push the reset button momentarily to (re)start your program.

ESP-01 Breadboard adapter

As you might know the pins on the ESP-01 module is very tight.ESP-01 adapter
This means that it can’t be mounted on the breadboard without shorting the two pin rows.

One solution is replace the straight pins with some angled pins.

Another solution and very commonly shown on the web is making a breadboard adapter. This way you can connect it across the middle of the breadboard without shorting the pin rows.

The adapter is made of two 1×4 or one 2×4 female header, two 1×4 male pins and a piece of prototyping pcb. my pcb has single islands and the soldering is shown on the photo. It works like a charm.

Next up – making the ESP-01 programming circuit.

FTDI FT232RL USB to TTL Serial Converter

Today I got my USB to Serial converter.
I need the converter for programming the ESP-01 I received a couple off days ago.
Actually I can program it with the arduino board but don’t want to.

I bought the converter on Ebay from a Chinese seller for the price of approx. $2 so properly not a origianal FTDI chip.
But hey! It works.

FTDI TTL Converter

Here is a picture of the board.

It has serial pin out at the bottom and mini usb on the top.
Along the sides is breakout of other, but not needed chip pins.

On the front it has a jumper setting for 3,3V and 5V.
Nice as ESP-01 is strictly 3,3V
