The plywood product I used was 1/2x2x4 G1S, $37 ea before tax in Ontario in summer of 2022. For the project infrastructure, four 1" x 4" x 8' knotty pine planks would be price competitive and less work to waterproof, but less convenient to transport....
I first visually look for shorts/opens, especially on the QFN or QFP and USB (shorts can be easily reworked with the Kester 2331-ZX flux pen; always clean and dry boards after rework; I use isopropyl alcohol and a toothbrush followed by running water)....
Clocks are an important part of practical digital design. Suppose you have a two input AND gate. Then imagine both inputs go from zero to one, which should take the output from zero to one, also. On paper, that seems reasonable, but in real...
UV-C bulbs use a dab of mercury plus a glowing hot filliment in a low pressure tube of glass to generate ultraviolet light that peaks around 253.7 nano meters, the optimal germicidal wavelength in the UV-C part of the spectrum. Not to be...
Make you the PCB and get the components and any standard 60mm 4-wire fan will probably do the job. I used a JMC "6015-12HB APW" that I had lying around. The exact the same fan is readily available on eBay.I used eagle to design my PCB, and the files...
Next step is to wire all the source leads on the MOSFETs together (the right lead when you're looking straight on at it), and also wire them to the one 2-pin female headers on the lower left side of the board (which will be connected to the positive...
Time to start putting together the low-side driver board with the CAT4101s. First step is to install the connector on the 11 x 8.5 cm protoboard. This is the spec'ed component, but if you can't find one that size, you can use another one up to 11.5 cm...
In this step we will add the video module and optionally the sound module at that point you'll be able to run demos and games written specifically for this setup. Unless you want to run MSX BASIC or MSX games then you may want to stop there. RC2014 +...
Multifunctional DIY DC to DC Converter Auto Step - Up Step - Down Boost Buck Solar Power Supply ModuleThis is a buck–boost converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude.Comparing with...
In case we want to use more demanding Odroid-XU4's instead of Raspberry Pi3's, we have to improve power source leads to lower lose. Keep in mind that 5x Odroid's can pull > 100W under full load. As a part of my Ph.D research was to accelerate operations...
Autonomous Cyborg Backpack Instructions:--Hardware Setup--Mount Dagu arms on rigid surface (such as a cardboard box or plastic container).Place arms/surface in backpack and seal backpack so arms do not fall out (possibly seal via industrial-grade tape).Mount...
I've had comments regarding the validity of using Geiger–Müller Tubes for a cosmic ray (muon) detector. Pointing out that Photomultipliers and scintillation panels are best, and yes the are far more effective. However, they are also expensive,...
