At this point I am just testing waters.

Ugh.  I would love to go in with you for 5 to 10 of those things but I just can't do it right now.  I do hope you round up enough people to pull it off.

Used to get freebies from Texas Instruments but they stopped giving stuff away

Recently they sent me a TLC5940NT and a TLC5940PWP three days after I ordered them; no cost.  While ordering the website offered six other chips that might interest me (I declined).

One time it 'offered' me a rather high-end ADC that could not actually be sampled, by me at least.  Maybe there are other levels of accounts, though they have sent me some very high end parts that I expect to be able to implement maybe in a few years...  smiley-lol

Seems familiar.  24 bit high speed ADC.  I think it had an SPI interface.  I very likely passed because it was itty-bitty.  The surface mount chips seem to be easier to sample.

Mine is definitely at the bottom of the pit so I consider TI to be very generous.

My order (through a friend, PayPal doesn't like my address) from Yourduino arrived, I finally got one through.

Shipping seems high in ratio to the total but that's because they charge so low for parts! Also the box (not bubble wrap bag) is well packed, padded and sealed.

2 wall warts, 1 5V and 1 12V
40 RGB leds -- at 5/$1 I don't need a specific use. Status led can be 1 of 8 colors easily.
200 220R -- will need 3 per led, they ran 1 cent each.
40 74HC595 Serial in parallel out shift registers -- yes I got more than just for the leds.
30 ULN2003 7-bit Darlington arrays (thought they were 2803's but these will do for the price)
40 PC817 Single channel opto-isolators -- car 12V to Arduino pin or vv safe and 1 step easy.

All shipped here for 40-some bucks. And yeah, the eBay Bottom Feeders will probably call me a spendthrift sucker or worse.

Sorry, we try to make it clear: you don't need a Paypal account at YourDuino, you can pay with any credit or debit card. Paypal handles the credit cards so we never see any customer card information.

Paypal has great security reputation: we have had 4000+ orders and zero Credit Card fraud.

And we will ship to the address you put on your order, not necessarily a Paypal confirmed address. 

Any problems with this stuff please email me: terry@yourduino.com

I'll try it myself next time, in about 2 weeks.

Got a new Makerbot Replicator off Ebay for around 2/3 the price from the official website. 

Replicator Article - https://www.inventables.com/technologies/makerbot-replicator-3d-printer

I have printing non-stop for about a month now.  Just had to purchase my first set of filament.  This thing is amazing, especially if you're designing something that needs prototyping and don't like waiting.

My latest dealextreme order arrived.

100 super magnets, 12mm dia x 1mm thick. I shall not want for small magnets any time soon. I like magnets.

10 x 1m heat shrink tubes of various diameters. I misplaced the ones I had, I actually need these.

2 x 5V regulated power modules with on/off button. For try-out, they were cheap. There is a DC barrel connector jack, on/off button, regulator, caps, diode, resistors and 8 pin header with one side as GND, the other as VCC.

3 x 20 Schottky diodes --  20 each -- IN4004 / 1N4148 / BAT85. Hey I wanted Schottky's and now I got em. Signal strength only which is fine. Now I can make piezo buttons that are even more sensitive? Or be able to cut .3V in a circuit. Or maybe do something more useful?

I bought a hc sr04 just a few days ago.
Don't know what to do with it though.

I bought a bunch of things from dx.com, ebay and futurlec.com. Have a few project ideas and lashed out for components for all of them. In the next 2-3 weeks I am going to be inundated with a treasure trove of components, sensors, microcontrollers and what not.

Regrettably, my sparkfun.com order didn't go through. :-/ No error message on the order screen, just a red span (sans error message) indicating something wasn't right, as well as a debit+credit for the order amount from my account. Have emailed support to see if we can work out what's up.

The most interesting (for me) things I have bought include:

- rf transceivers ($5.60 a pair from dx.com!?)
- high powered rf transceivers
- wireless rf remote control + receiver
- (water) flow, CO2, PIR, relative humidity & temp, ultrasonic, 6DOF accelerometer + gyro and GPS sensors
- bluetooth transceivers
- slipring
- Atmel 328, 84 & 85 microcontrollers + IC sockets
- strip and proto-board
- SD & micro SD modules

Nice! Would like to see some pics of what you've printed?

Haven't printed anything worth a Nobel prize..  I am in the process of teaching myself 3D design and tried a number of CAD programs.  I think I found one that suits me, Solidworks.

Here is a clevis that costs around $12 and made it for pennies


Other things include a hood for my camera and some upgrade parts for the 3D printer.
