<hr />
<div>=Introduction=<br />
<br />
This tool cuts sheet material such as card, acrylic and wood. At a reduced power rating, it will mark the surface without cutting all the way through. The laser cutter focusses a point of high-energy light into an area just a fraction of a millimetre across, and it instantly vapourises the material that it touches.<br />
<br />
This information sheet does not describe how to create a computer file containing the shape to be cut.<br />
<br />
The maximum size of material is 680mm by 500mm. That's a little larger than A2 size. Maximum thickness depends on the type of material and it reduces as the laser tube ages. 3mm plywood, 3mm MDF and 5mm acrylic are about OK.<br />
<br />

=Safety=<br />
Two things to remember: Don't use it with plastic compounds containing chlorine (PVC, poly-vinyl-chloride for instance), and don't ever look at the laser beam when it's cutting.<br />
<br />
There are protective glasses allowing you to glance at the beam while cutting, but these are not recommended for continuous viewing<br />
<br />
Hazards include:<br />
<br />
* Chlorine gas fumes when cutting prohibited materials<br />
* Eye damage from looking at the light beam<br />
* Material catching fire when cutting too slowly<br />
* The mechanism crashing into something on the cutting table that's too high<br />

=Instructions=<br />
<br />
==tl;dr==<br />
*The software is on the windows 'lasercutterpc'<br />
*Ruida RDWorks (<s>https://www.thunderlaser.com/laser-download</s> <s>http://www.rd-acs.com/newsinfo/1078010.html</s> https://www.rdacs.com/download?id=1&m=software&a=RDWorksV8&v=4<br />
<br />
sends commands over the network and will do basic design BUT....<br />
*Most people export from Fusion360/ Inkscape etc. into a .dxf format and then import that (or .ai files) into RDworks<br />
*Suggestion is that you install RDworks and play. An improved English translation of the RDWorks 8 user manual can be found [https://lasermeister.ee/wp-content/uploads/2021/04/RDWorks-V8-manual.pdf [here<nowiki>]</nowiki>]<br />
* Laser cutter induction document [[File:LaserSummaryGuide.pdf]]<br />
<br />
==Before use==<br />
<br />
Switch on the laser cutter using the illuminated green rocker switch on the right-hand side. Check that the cooling water reservoir is not empty and that the pump is running. Check for a gentle air blower at the cutting head.<br />
<br />
Switch on the computer monitor. The computer itself is left normally running.<br />
<br />
==Preparation==<br />
<br />
Using the computer, keyboard and mouse, open the RDWorks programme. There are two versions. Version 8 is recommended. Use File > Import to read in a .dxf, or use File > Open to read a .rld<br />
<br />
Select the shape that is to be cut, then allocate a colour from the strip of colours at the bottom of the window. Double click the colour as it appears in top right of screen, and set the power level and the speed appropriately. Cutting all the way through wood requires a high power level, cutting through card or plastic sheet can be done at a lower power level and a higher speed.<br />
<br />
Optionally, text or patterns can be selected in a different colour, and the speed and power settings may be chosen for marking without cutting. Large areas or designs with half-tone regions may require the 'scan' setting to be used.<br />
<br />
Open the cover on the laser cutter and position the material to be cut onto the honeycomb support. Use the arrow controls on the top panel of the laser cutter to move the cutter head to be above the material. Adjust the height of the honeycomb support using the push buttons on the right-hand side of the laser cutter, so that the head is exactly 20mm from the surface of the material. There's a plastic guide to help with the measurement.<br />
<br />
==Using other programs==<br />
* [[Inkscape to Laser Cutter via Illustrator]]<br />
* [[OpenSCAD to Laser Cutter]]<br />
<br />
==How big can I cut?==<br />
<br />
There are two parts to the question, how big a sheet can I put in the machine, and then what's the biggest part I can cut?<br />
<br />
1) The machine can take a sheet 740 x 600mm, but the laser can't reach all of that area.<br />
<br />
2) The machine can cut in an area 680mm x 500mm (a shade larger than an A2 sheet of paper)<br />
<br />
==Using it==<br />
<br />
On the screen note the 'origin' mark, a small green square. Manually drive the cutter head to a position over the material where the origin should be.<br />
<br />
The cutter head has a small red light beam that shows where the laser beam will cut. The accuracy of the red beam is affected every time the height is changed, so you may need to re-calibrate it.<br />
<br />
Close the top cover. Back at the computer screen, click on the button 'Send to cutter' and the laser cutter should start to operate almost immediately. Sometimes there's an error message, in which case just repeat the click on the 'Send' button. If it still won't work after a few tries, switch off the laser cutter and switch it back on again. <br />
<br />
At the end of the cutting process, the laser cutter emits three quiet beeps.<br />
<br />
==When finished==<br />
<br />
Clear up any cuttings from the honeycomb support. Switch off the laser cutter and the extractor fan. Exit from RDWorks, turn off the computer monitor leaving the computer switched on.<br />
<br />

<hr />
<div><big>Ham Fair 10th June</big><br />
<br />
''' 9.00am Set Up '''<br />
* '''9am''' 2 people to help load gazebo and tables into camper van from St Richard's Church (opp Tesco Express) <br />
* '''9am''' 2 other people to collect from Little House: RML Banner, A5 leaflets, two wooden trays and two boxes of acrylic shapes (Penrose and Einstein tiles) with three A4 leaflets explaining the tiles. Also collect the wind turbine and the tripod stand. These could be hand-carried to the site as they won't fit into a cargo bike.<br />
* '''9.30am''' All 4 people proceed to Ham Common to put up the gazebo, set up the tables and put up the banner. Same location as last year. Stalls 5 and 6 in the Green zone.<br />
<br />
''' 11am Morning session until about 1.30pm '''<br />
* Carl will need space to demonstrate how to create giant bubbles<br />
* MartinC may have a wind generator to display<br />
* The Penrose tiles and Einstein tiles will be on show<br />
* MartinL will provide leaflets describing the electric Isetta project<br />
<br />
''' 1.30 Afternoon session until about 3.30pm '''<br />
* Continue to show and tell what RML does and hand out leaflets. <br />
<br />
''' 3.30pm or 4pm Fair closes '''<br />
* Put away everything, take down the gazebo and fold up the canvas covers, load it all into the transport. <br />
* Give a hand unloading and putting away at St Richard's Church. <br />
* Return other stuff to Little House.<br />
* HUG have some display material they want stored at Little House till next year. They will deliver to LH and we will find storage space on another day.<br />
<br />
The gazebo needs 6 people to open the frame and put the roof on. It needs 6 people to close it down again. All 6 are only essential for a relatively short period of time. HUG is relying on RML to provide 4 of those six people at the start and the end of the day. We don't have any confirmed volunteers for those two tasks.<br />
<br />
For staffing the stand during the day, we can probably have MartinL and Carl for the morning. Jane and PeterH will do some of the afternoon. If anyone else is willing to help out for a short time to give those people a break, it would work very well.<br />

<div>==Self-assembly==<br />
At RML, we have a whole stack of cheap AM radio receiver kits to practice assembly and learn more about electronics. As of October 2015, a young adult is building one. And in March 2023 two people have started assembling from the kit. The instruction sheet is in Chinese. <br />
<br />
English language instructions here: [http://f6kfa.fr/wp-content/uploads/2019/12/Receiver-S66E-Manual-en.pdf Receiver-S66E-Manual-en.pdf]<br />
<br />
Some software-defined radio receivers have also sparked quite a bit of interest from the maker/tinkerer community:<br />
<br />
==RTLSDR==<br />
"rtl-sdr" is a generic term for cheap USB digital TV (DVB-T) receivers that use the Realtek RTL2832U chipset, which can function as general purpose software defined radios (receive only). All rtl-sdr compatible devices employ the RTL2832U as an ADC and USB controller, but different RF tuners may be used. '''Note that rtl-sdrs do not transmit!'''<br />
Typical specs (some depend on specific tuner):<br />
Device Cost: ~£5-20 (Look on eBay, Amazon, or AliExpress)<br />
Frequency range : 24 - >1760 MHz (100 KHz - 24 MHz in direct sampling mode)<br />
Max sample rate: 3.2 MS/s (2.6 MS/s in practice)<br />
Resolution: 8 bits/sample<br />
Noise figure: < 4.5 dB<br />

* [https://www.reddit.com/r/rtlsdr reddit RTLSDR forum]<br />
<br />
==SDRplay==<br />
The RSP (Radio Spectrum Processor) from SDRplay is a Software Defined Radio which can turn a PC into a general coverage receiver spanning Long Wave (100KHz) through to Microwaves (2GHz). The SDRplay is home-grown in the United Kingdom and offers a much wider set of capabilities than the RTLSDR.<br />
Device Cost: £118.80 <br />
Frequency range: Total coverage from 0.1MHz to 2GHz<br />
ADC performance: 12 bit native ADC<br />
Max Sample Freq: 2MSPS – 10.66MSPS<br />
10.4 ENOB<br />
60dB SNR<br />
67dB SFDR<br />
