Lasercutter

 

 

In summer 2021 I decided to make the plans for a lasercutter. I found the project Y400/Y1200 from Further Fabrication pretty interesting, followed the video's and finally bought the plans from Rob Chesney. In November 2021 it was ready after a 5 week build. I made some upgrade chassis parts in aluminum 6082 (instead of wobbly 3d printed mirrormounts, carriage plates) to make it even more strong and made a 4040 extrusions table under it. The outer plating was ofcourse drawn in Fusion360 and milled on my CNC. Some chassis and electronics changes were applied to answer my own needs. Best was buying an autofocus ultrasonic sensor, with one touch on the Ruida controller your laser is in focus. I also made my own Bofa filter casing for fume extraction and they say these filters block 99.997% of the fumes, now I can easily use the laser in my house without spilling warmth in my mancave and without suffocating from smoke.

I will mainly use this to cut and engrave wood (decorations), acrylic (Nixie/VFD clocks) and engrave aluminum (frontplates)

Furniture

 

Yes, HMR-Audio started making furniture after the pile of audio equipment became to large to show and replace easily in the wooden rack I once created from wood.

In 2019 I had build the CNC milling machine based on aluminum extrusions from Item Systems.

So why not make a new rack with Item Systems profiles (170cm x 60cm) !

Item Systems has a wonderful online tool to design your own rack, table or whatever.

If you want something cheap, stop reading ;-).

In this case I wanted to have a large table on wheels and with 3 glass layers and alubond panels.

 

The hardened glass was made on size  by GlashandelOnline and Alubond panels from Plexideal in the color RAL9006.

 

You see the holes for the cables and connectors, done on the CNC milling machine.

 

Well, It did not stop. My wife was so exited that she wanted a table in the same look and feel. She got a table and cupboard !

CPLD/FPGA

 

It is highly unusual to use this in hobby projects but since I started programming hardware devices in 90's, when Arduino and Raspberry did not exist, I am able to program these devices most in VHDL language.

I am used in using the Altera devices from classic to new devices. I do even own a Pentium4 PC 600Mhz with the latest version of Maxplus2 for programming classic devices as EP900 (25 years old platform). Currently Altera is owned by Intel and does provide Intel Quartus Prime software suite and most devices are programmed via JTAG.

The big advantage is the very high speeds these devices run and can run loads of parallel tasks on different clock busses.

And it is hardware that runs (fuses get programmed in logical blocks), not a processor running software.

 In the old days I designed hardware were we controlled the grid (electricity) of South Hollland with these kind of devices. 

My early hobby nixie clocks and CD-player were running on FPGAs.

SMD soldering

HMR-audio has small SMD reflow oven and is able to do the soldering for you. HMR-audio also owns a manual dispenser to set dots of solderpaste.

Many pcb manufacturers can also provide you with a solderpaste stencil. Youtube has many videos on how to apply.

You can contact me with the contact form.

Arduino

 

I am able to write programs (in C) for most of the Arduino processors.

It can be as simple as a delayed output or complete cd-player interfacing with (touch) LCD panels and IR remote control.

Do you have an idea but like to have it physically in your hands ? You can contact me with the contact form to discuss the possibilities.
