I printed it on a full page label using an ink jet printer. I laminated it with clear packing tape then cut it to size. See the ZIP file (WORD) and PDF attachments below. MD5 for ZIP file is 8DFBED52BD713026C776B4490838C00C Header label LEDandSwitch PCB X6.pdf (133 KB) Header label LEDandSwitch PCB X6.zip (12.6 KB)

Arduino Pro Mini interface board. Plugs directly into the bus lines of the breadboard, and has both male and female headers along the side. ESP-01 Programming board with integrated 3.3v regulator and easy access to the GPIO pins as well as a header for connecting an FTDI board. Not my best work, but it's functional, and it was about 20F in the workshop when I put it together.

If you have a tight fitting head on the screw, you can cut it down with a file and a electric drill. [C.jpg] To protect the threads, thread the screw into a standoff. [screw head.jpg]

A few from my palette of neat tricks: A pair of pliers with an elastic band around the handles makes a very convenient desk vice for soldering. CAreful of your fingers if it slips and they snap shut! I have the scars to prove this hurts :frowning: Blu tack or putty can be used to hold things in place while soldering, but can leave residue if the blutak gets hot. Servo leads (JR/Futaba) make convenient 3 pin leads with already attached male or female header pins. They are cheap and available in large multi-packs. A simple hardware store 20W/30W/50W 12V halogen spotlight bulb can be used to create a nice hefty load on a DC circuit. You can use the built in LED of the arduino to flash error codes when you have no serial or screen attached. Blink the LED as a heart beat, on error, flash it much more rapidly. So 1 flash = success, n flashes = error code.

Make yourself a simple but very useful Logic Probe with Logic Pulser. Resistors, diodes and LEDs are 1206. [Probe] [2018-01-30_20-51-09.jpg] [2018-01-30_21-17-36.jpg] [2018-01-30_21-18-06.jpg] EDIT D2 has now been added.

I find there are many times when I need to access an Arduino header pin with several external devices. You can make a simple interface with male and female headers. Cut a 6X1 male header and two 6X1 female headers. Solder them as shown in the images below. If you have a long pin (stackable) female header, you 'don't need the male' header. :confused: [2018-02-04_15-44-05.jpg] [2018-02-04_15-44-47.jpg]

Neat... :slight_smile: :slight_smile: :slight_smile:

Got to get my inventory under control. :confused: I did have some stackable female headers. These turned out much better. [2018-02-06_21-33-35.jpg]
