Can you shows bit more on this angel eye thing, please? I recently made a 2 color indicator that works off an existing signal. Had a lot of community help with it. 2 or 3 LED colors on a single digital pin - #32 by chrisknightley I'm interested to see how yours works.

@er_name_not_found It looks like an anti-parallel LED to me. https://electronics.stackexchange.com/questions/408880/antiparallel-led-circuit BTW, there are also ready-made products. https://www.ebay.com/sch/i.html?&_nkw=led+bi+color+2pin

I use two LEDS and two pins yes. One LEd for the inner light and one for the ring light. With two lights you can use many combinations.

THT foam compression tool See also: [image] Share tips you have come across General Electronics DIY Circuit Board Holder See post 935 also. If you have been following this thread, you will know several magnetic tools have been discussed. Existing magnet tools can be easily turned into a new tool set as shown in the images below. The two magnetic High Boy stands can be fitted with locking binder clips to form a circuit board holder. Commercial version costs about $130.00 USD. The DIY version costs about $2.00 Not shown in the images below would be a component arm with foam pad; this a… A commercial PCB holder/soldering jig is quite useful but expensive and takes up a lot of space on your work bench. We can make our own version of this jig. Seeing we already have our magnetic High Boy tool set, lets make a compression tool end for soldering THT components flush to PCBs.

The foam compression tool end can also be attached to the Torsion Spring Clamp made earlier. [image] Share tips you have come across General Electronics Torsion Spring Clamp Soldering a THT component or daughter card to a PCB can be frustrating at times. Before soldering you must make sure that the component is flat against your circuit board. You can use ‘Masking Tape’ or ‘Blue Tack’ to keep the part in place before the PCB is inverted. Torsion Spring Clamp (TSC). Make a torsion spring clamp to hold THT components while they are being soldered. When making the clamp, select a spring that has a reasonable amount of strength.

Bench Block When hammering on your work bench it is nice to have a Bench Block tool. This gives you several different surfaces to hammer items on. Not only does the tool protect your work surface, but the rubber base in this version also keeps the hammering noise down. The rubber is also a non-slip support for the inserts and the rubber can be hammered on too. I have to make a few wooden inserts as backstops for drill items. I will use the nylon insert as a template to be used with a flush trim router bit. [1] [2] [3] [4] [5] [6] [7]

I looked for answers to "Programmer not responding" on upload attempt and it was only after I remembered that the UNO clone manufacturer had used a special USB chip (CH340) and that I needed to download and install their driver which finally led to it working; now, to re-install the beta release if the Arduino IDE.

CH340 Added to the index. Yes, the CH340 driver would need installation.

It seems that a driver upgrade included in a recent Windows update is the cause of this problem. The affected users have found that uninstalling and reinstalling the CH340 device fixed the problem. I'll share the instructions you can follow to do that: Close Arduino IDE if it is running. Connect the Arduino board to your computer wi…

Blind Standoffs, Mounting Feet for PCBs See also, post #1110 We have covered chassis PCB mounting without the need of drilling through the chassis itself. This method used a M2 brass insert in an Acrylic foot; the height of the finished foot is about 3.5 mm. The assembly is glue welded with DCM (Methylene Chloride) to the chassis inside surface. There are, however, times when the 3.5 mm brass insert foot is too high. [image] Share tips you have come across General Electronics Prior to using 1/8" material for blind attaching parts to a panel, I used two 1/16" pieces of plastic. This is still a very viable and strong way of attaching things to a surface without drill a hole through it. Plastic mounting shoe [2017-02-16_10-30-06.jpg] .

This is especially true if the are no mounting holes in the PCB. Below shows one way to attach an Arduino Pro Mini to the top of a case. Note: no holes are made in the project case. If the Pro Mini fails, just throw the assembly away with the Pro mini. [1.png] [2.png] .

A while back we discussed making a blind standoff. The nut used in the blind standoff can be quite difficult to tighten as the screw rotates. Using a modified brass standoff, we can make an effective tool to easily accomplish this task. Note: the brass standoff is made from brass and is tapped for an M2 thread. The very useful razor saw… About 6 months ago I ordered Phillips M2 FLAT headed screws. The screw heads are only 0.34 mm thick with a diameter of about 4 mm. With the flat headed screws being so thin a shorter PCB mounting foot can be made. The following method does not require a brass insert. Used here is 1.6 mm Acrylic plastic feet that measure 8 mm by 8 mm. For the foot to lay flat on the chassis inside panel, the screw head needs to sit in a counter sunk well. A square cut 6 mm milling bit is used to counter sink the screw hole to a depth of 0.4mm. A drill guide, made from PCB material, is clamped on top of our work to prevent the milling bit from skating on the Acrylic plastic, when making the counter sunk hole. The images below discuss the process for making the shorter mounting foot.
