The $20 10 MHz heat controlled crystal oscillator was bang on! https://www.amazon.com/dp/B0BBVTPPHZWho says hot glue isn’t for professional applications.You can see how the ultrasonic cleaner damaged the 6 aluminum blocks on the heaters. I’m holding an uncleaned block.Jig to help attach aluminum vial heating blocks to the hotplates. The important dimentions are the locations of the blocks. This jig lets the hotplates be moved while holding the blocks in place.SMC100 Configuration GUIGot the Newport SMC100 motor controllers hooked up for the automated probe station.Here is what’s left of the DELTA remote chemistry lab.Cleaned out the DELTA robotic lab fume hood.MHP30 hotplates in action with vials.Two MHP30 hotplates setup in the Opentron OT-2 for a demo for the National Renewable Energy Lab.MHP-30 hotplate heating element.MHP-30 hotplate heating element.MHP-30 hotplate with its I2C breakout cable.I2C mux board for communicating with up to 8 MHP-30 hotplates over I2C. This is needed because the Arduino Mega can only be an I2C slave on one I2C interface.Bottom side of the I2C mux.A clean bench ready for new projects!A messy bench is a productive bench.Finished printer!!!More printer progress.Getting started on building my Prusa 3D printer.My Prusa MK4 kit finally arrived!RAMPS 1.4 CNC controller.Another view of the camera.Webcam mount for looking at the PCB and components.Initial nozzle holder designInitial nozzle holder designInitial nozzle holder designDIY pick and place nozzle shaft. It will rotate.GPS expansion card I messed around with designing.RP2040 LED bar expansion card idea that I was playing around with. It would have a buzzer and maybe a vibration motor. That way you can use it for all sorts of notifications.Close render of the RGB LED matrix.Close render of the RGB LED matrix.Front of my version 2 panel.The back of my version 2 RGB LED matrix in a 2 by 1 panel for assembly..The back of my version 2 RGB LED matrix.Arya included my LED matrix in one of her blog posts on HackadayOfficial Framework LED matrix module.Official Framework LED matrix plastic shell and ribbon cable.My version 1 RGB LED matrix along side the Framework input module test jig.First LED test!!!A look at the bottom heating elements. Also the insulation on the bottom of the oven.Back panel of the oven is now insulated.Insulation on the roof of the oven. Also a look at the top two heating elements.Stripping out the electronics from a toaster oven.DIY reflow oven shelf.Version 1 of my RGB LED input module for the Framework 16 laptop.Version 1 of my RGB LED input module for the Framework 16 laptop.I have a lot more respect for people who layout PCBs as their job. It’s hard work.Max brightness LED matrix module test.A look at the engine bay of the solar car.The solar car that I helped build looking beautiful in the sun.
