• On this page I am going to show you my equipment & tools that i work with. Some of them are homemade and some of them are quite old, but they fulfil their task.

    1. Measuring Instruments
      • Analog Oszilloscope
        An old Hameg HM312 1-Channel oscilloscope. Bought it about 10 years ago in used condition, but it works well.
      • Digital Storage Oszilloscope
        An Atten ADS1102CML 2-Channel DSO.
      • Multimeter
        Some cheap multimeter from eBay. My old one had no capacity-meter and did not beep in conductivity mode, so i bought this one recently. Also has an internal an external temperature sensor and frequency counter.
      • Caliper
        Essential tool for measuring, especially for parts to enter them into the eagle-library.
    2. Soldering tools
      • Soldering iron
        Temperatureregulated soldering iron without temperature display.
      • Soldering iron tips
        Some fine tips for SMD-soldering and some bigger ones for bigger parts and desoldering.
      • Various needles, scalpels, brushes
        Needles and scalpels for scraping of excess toner from ironed layouts and brushes to remove fluxresidue.
      • Stereomicroscope
        Not too expensive stereomicroscope from eBay. Provides 10x,20x,40x,50x,80x and 100x magnification. Greatly simplifies soldering of SMD parts.
      • Magnifing glasses
        One goose-neck magnifing glass for SMD-soldering and two lens-assemblies from old scanners, which provide very good magnification for inspection of etched boards.
      • Helping hands
        As the name implies, those are quite helpful in holding the boards while soldering the parts.
        Never can have enough of them.
      • Desoldering pump
      • Normal and fine solder wire
      • Various tweezers, pliers and wire cutters
    3. Machines
      • Drilling machine
        Rather cheap drilling machine from the local hardware store. Good for wood, bad for metal. The holes are not very round 🙁
      • Proxxon with drill press
        For drilling circuitboards.
      • Files, saws and taps
      • CNC Router
        (Coming soon)
    4. Misc.
      • Various screwdrivers for all sorts of screwheads
      • Power supply
        Dual output laboratory power supply.
      • Homemade square-wave generator
        555-based squarewave generator with adjustable frequency and dutycycle as clocksource for breadboard-projects.
      • Breadboards
        One big breadboard for big projects, a smaller one for quick test circuits and one as interface for the AVR-Evaluationboard.
      • AVR-Evaluationboard and programmer
        A board which can house some different kinds of AVR and provides some basic I/O (2 Leds, 3 buttons, piezobeeper, rs232 and ISP) and one big port where all I/O pins are available for external circuitry. The ISP-Programmer is connected to the PC via USB and can be used from within AVRStudio.
      • PC
        Some old P-III box with 128Mb of ram and a 4GB SCSI-Harddrive running Win98se. Win98se does not prohibit direct access to the parallel- and serial-port, so it is ideal for testing.
        Runs AVRStudio, TurboC++ and QBasic. (Second PC with Linux waits for a kvm-switch).
      • Panel
        Homemade socket panel with 5 switchable 12V outlets, 5 switchable 5V outlets, 6 extensions for power, 1 extension for oscilloscope, 1 extension for D-SUB25 and connectors for the parallel/serial ports of 2 PCs. Saves a lot of cable tangle and makes everything accessible directly on the table.
