A quick five-minute hack to use the external ammeter while retaining PC control of power settings EDIT: MORE INVESTIGATION IN PROGRESS. DON’T TRUST THIS. This article is for the Cloudray M100 Laser Power Supply , but it should apply across the entire M-series of Cloudray Supplies. Full Disclosure: This is an affiliate link. Even if you never intend to order a massive CO 2 laser, just clicking that link will still help us stay afloat – Thanks! The power-supply comes with this sweet display screen, letting you know exactly how much power you’re actually running! Not necessary, but cool. The problem is that when this is plugged in, the knob on the left side will override the power-setting that your laser control software (lightburn, etc) is sending. Cloudray claims they have a switch on the PSU itself to disable this, but our supply shipped without said switch. Luckily, this is easily remedied with a pair of diagonal-cutters and a tiny screwdriver! Remove the knob itself by pulling straight off Insert the screwdriver to remove the back panel Remove the PCB/Screen assembly from the housing Gently push on the screen Pry the retaining tab back just far enough for the pcb/screen assembly to move slightly Repeat this for each retaining tab, working around the screen multiple times Once both the PCB and then the Screen have passed the tabs, the assembly will slide free Using your diagonal cutters, snip the center tab of the potentiometer You can also desolder the entire potentiometer from the PCB if desired Use the screwdriver to bend these tabs for additional clearance Reassemble by gently sliding the pcb/screen back into the housing, and pop in the back plate Make sure the PCB slides past the retaining tabs Done! And of course, we have pictures for all of this: Bonus: How did we figure this out? / Why does this work? We knew there were only two options for the layout of this control board. Either: 1) There is a custom microcontroller on this control board 2) This board has only an off-the-shelf display driver, and passes the other signals through First, we checked the IC on the board…. if we could look up a part number that would be a giveaway – however, it was completely blanked out. So we investigated, trying to figure out where the signal from the potentiometer (signal is always the middle pin, with V+ and GND on the two sides) was connected to. Probing with a multimeter, we found a direct connection (0.2 Ω – close enough!) between the center pin and pin 4 on the RJ45 jack! This points to the pass-through option, so we snipped it – worst case, we’d have to solder it back. We put it all back together and…. we were right!

Am letzten Tag des offenen Hackspaces kam haben wir uns überlegt, solche Treffen ab jetzt in gewisser Regelmäßigkeit zu machen. Zwar heißen wir ja immer alle Interessierte willkommen, aber an diesen Treffen möchten wir explizit alle einladen, die sich für Spaces, Hacking, Basteln, Elektronik, Computer u.v.m. interessieren oder mal schnuppern wollen. Neben den Dienstagabenden werden wir versuchen das einmal im Monat auch am Wochenende zu machen, um möglichst vielen die Gelegenheit zu geben. Ein erster Termin ist der 26. April ab 16:00 Uhr. Alle solchen Termine können nun über den Eventkalender oben auf der Startseite gefunden werden.
Liebe Kohlenstoffeinheiten, Hallo Nerdschaft!, Liebes Chaos, bei allerbestem Frühlingswetter und 20er Temperaturbereich fand vom 11. - 13. April das erste Geekend Weekend in Halle (Saale) statt. Endlich mal Zeit was zu machen! Mit 40 Wesen auf 700m² gab es ohne viele Vorträge mal echte Freiräume. Mit Willkommensbadge und dem Bingozettel in der Hand ging es für die meisten erstmal an den Laser um den eigenen Namen ins Feld zu lasern. Einchecken, ankommen, alkoholfreien Tschunkslush schlürfen und erstmal Überblick verschaffen.
