DIY USB TO SERIAL CABLE FOR $3! Jonathan Thomson submitted this useful article about converting a low cost cell phone USB cable into and easy and cheap way to connect to an Arduino microcontroller setup. Jonathan found a cable for less then $3 which can be hacked to perform the same function as the typical $20 FTDI USB cable often used in Arduino projects.. Jonathan submitted as part of the uCHobby Giveaway project HACKING A CAT LITTER BOX Now thats some nice hardware running that thing it just cant be more hackable. First thing i would do is plug a programmer on it and read out the entire program, so you can save it in a safe spot in case you want the original functionality again (I hope the pics memory is not locked, but if they put a really obvious programming connector on it i don’t think it is.)

– January 22, 2018 ------------------------- BAD DESK LAMP + 3D PRINTING = COOL CAMERA MOUNT + USEFUL HANDMAGNIFIER
Useful 3D Prints
I recently purchased a hot-air gun + soldering iron station from X-Tronic which came with a desk lamp magnifier. The desk lamp was not functional so I took it apart to fix. It was made so poorly, I considered it too dangerous to use. It went on the scrap pile. Today, I decided to make use of it. The base with its flexible stalk became a nice mount for my new webcam. The desktop magnifier part became a nice large handheld magnifier. I designed the parts using Fusion 360 and a digital caliper. Printed on my Creality CR10 using Maker Geeks Raptor Steal Blue Filament. Note the blue magnifier handle and the blue bit on the lampstand where the camera is attached. This will be my latest answer to the common question… “What USEFUL things can you do with a 3D printer?”Continued…

– December 11, 2017 ------------------------- AA BATTERY PACK TO 3.3V FOR IOT PROJECTSI
tweeted about my experiments with the AAT1217 switching supply controller a few days ago. I found the chip in a product design I was evaluating. It looked like a great answer to the power problem in an IoT project I’m working on. I ordered a few from Mouser and some breakout boards to try. My first experiment was to fire it up on a breadboard with a load and a AA battery pack. I recorded the performance while the batteries drained into a constantload.
RESULT SUMMARY
* Rock Solid 3.3VDC at 75mA continuous * More than 15 hours. I missed the very end, it went longer. * From a pair of AA Duracell Alkaline batteries. * Simple to use, 1 inductor, 2 caps and a resistorRESULTS

Some data is missing above. I was doing this all by hand and just stopping by now and then. The test ran much longer than I expected it would. I had to sleep. The 12:00 reading was an unexpected wake up with the 14:15 being a return to bed mark. The pack was all but dead at this point, but I don’t know how much longer it took to diecompletely.
TEST CIRCUIT
I used the example circuit from Skyworks for the AAT1217 breadboard. The part was a pain to solder to the adapter I had. The adaptor was for a SOT type package with different spacing, but I made it work.The
AAT1217 only needs an inductor and two caps. A resistor is used to hold the enable high. The output was 3.3V with about 100mV of high-frequency noise/ripple. I added a 0.15uF ceramic cap to cleanthat up a bit.

The 22Ohm resistors were used to make a 44 ohm load. At 3.3V this would be a continuous 75mA load.OBSERVATIONS
The AAT1217 works great. I will do some more test, but I plan to use it in future projects as the battery power solution with 2 AA batterypacks.
Battery lifetime was considerably longer than expected. I probably have a flaw in my test somewhere. Based on discharge curves an Alkaline AA would give about 2.4A/hr @100mA and discharge to about 1V. The charge after about 1V is not significant. I estimate that the batteries should have drained in lessthan 8 hours.
The AAT1217 is specified to run down to 0.8V which would pull the pair of series AA batteries down to 0.4V each. That might yield some more time but not double the estimate. My assumptions are that a AA battery is all but dead when it’s at 1V. But that might be wrong while under load. The load was close to the 100mA load a AA is designed for. Efficiency was much less than expected. I was hoping to see closer to 90% which would make a significant difference in battery life. I’m thinking the inductor used is not the best for this application. I chose it to be easy to use in a solderless breadboard. I plan to get a few better parts when I do a more controlled test. I used a new Rigol DM3058Eand a Fluke
175 for measurements. I hoped to use just the Rigol as it should be able to display two measurements, voltage, and current, at the same time but I did not figure that out. The Rigol DMM also has an easy to use serial output so I could record one of the data values simply by logging it. I might create a QT app to do a DMM logger, especially if I can get the meter to do bothmeasurements.
When I repeat this test, I’ll pull out a device I designed and built if for some consulting work recently. It could be adjusted to be an ideal tool for this kind of testing. Posted in Uncategorized.

– January 29, 2016 ------------------------- UCHOBBY SITE ON NEW HARDWARE. Those of you that visit often have probably noticed that my site has been down often. The problem with that server has not been definitively located so we have moved to a new system. We are looking forward to getting back to regular projects using the new Arduino, Raspberry Pi and ESP8266 boards. We have also gotten into 3D printing, it is an addiction, have been designing and printing a bunch since Christmas when a LulzBot TAZ5 was added to the lab. If you have been watching the Twitter feed (uCHobby) , you have seen some of the recentcreations.
For new toys we have an Arduino Zero, Arduino 101
, and the OAK boards from their Kickstarter. Look for or suggest some projects usingthose.

------------------------- CHINA GOODIES – GEARBEST.COM – ARDUINO BITS A review for some Arduino related items we recently received from Gearbest.com . A cheap Arduino Mega compatible board, LCD/Keyboard shied, Acrylic mounting plate for Arduino and a simple cable. Each one with some details on cost and function. Click on the pictures to visit the product page at Gearbest.
Generally, I’m amazed at the variety and often surprised at the quality of the products from China, considering the price paid. Yes much of it is lower quality, you are not going to pay $1 for something that would normally cost you $100 and be happy with the result. One of the major differences you will notice when purchasing from China is the time it takes to receive your items. Typically you will wait 2 or three weeks but it could take longer. You will also notice that most suppliers don’t charge for shipping which surprises me. The language barrier is evident on the Chinese sales sites. You will notice that everything seems to be Arduino compatible, even things like LEDs… They have picked on the Arduino craze and milk it like crazy. The descriptions of the products is often strangely worded and it’s often clear the writer does not understand the product or the market. But it’s good enough that you can find what you need. I wonder about starting a consulting gig, where I would go to these sites and get paid to clean up the product descriptions. They ought to hire some Arduino nerds to clean up things, they would benefit inmore sales.
LCD1602 CHARACTER LCD KEYPAD SHIELD:
$4.47/EACH
Pretty much exactly what you see. A standard 1602 2×16 character display with backlight and 6 buttons. The LCD is interfaced using 4 DIO signals and the keyboard is done using a resistive ladder trick so that only one A/D input is used. One of the switches, on the far right, is a reset button. One complaint on this.. it’s easy to hit reset when you mean to tap a regular key. Also, it can take some tweaking to get the values just right in your code to read the switches. There are other sources for the same design, I feel that this lower cost version works fine. ARDUINO COMPATIBLE DIY MEGA 2560 R3 BOARD AND KEYPAD SHIELD 1602 LCDBOARD :
$22.95
This is a combination of the above LCD Shield and an Arduino Mega 2560. Read above for more about the shield. The Arduino Mega works fine and seems to be of high production quality. The quality on this is apparently equal to any board I’ve ordered without regard to the supplier. My biggest concern here is that it feels wrong to get so much for so little in cost. I personally would order my Arduino boards from a local registered supplier such as Sparkfun for $50/each. With that said this board works great and is very inexpensive, if you are on a tight budget and don’t mind waiting… ARDUINO UNO R3 COMPATIBLE ACRYLIC PLATFORM PLATE:
$2.08/EACH
This acrylic plate is convenient to use with your solderless breadboard to keep your wires from pulling out of the Arduino connectors when things move. Not much else could be said about this product. It works as designed. Simple and inexpensive. EXTENSION CABLE FOR ARDUINO – 8.5 INCH / 21.5CM:
$2.04/EACH
Another simple product, just an 8-pin header connector cable. Funny they mention Arduino in the name but no Arduino I know of has an 8-pin header. Some have a 6-pin one… The quality is good and the price is amazing. These kinds of cables require hand assembly which drives the cost. In China, labor cost arelow, obviously.
