He has many achivements to his credit; From converting a Thomas Saf-T-Liner, a flat-nosed diesel school bus into a family camper To a DIY Op-Amp Hot Tub Temperature Controller.

DIY Op-Amp Hot Tub Temperature Controller

Look at Mr. Jake von Slatt, How he done things. This is what we learn from him …SteamPunk Workshop Guitar Amp

Jake’s School Bus Conversion and Other Projects

Jump into the problem and solve it, See the way a Creative DIY Enthusiast solves an automation problem at home. The Job gets done this way, such seasoned people are rare. Now the idea is …

Think – Deliberate – Draw – Build – Test – Install

We all get stuck at the ‘Deliberate’ step, If its team work, a few should leave the desk and the conference rooms and start Prototyping and Simulating. This helps understanding a tough problem. Better still find a fast and simple solution.

Then there is that Sensational Site That Jake Built – The Steampunk Workshop. This is where it all Happens.

Perpandle has a new Look – LED Lighting

The Center piece is a bamboo tube. The bottom of this pipe is a brass part. A autotransformer dial is the big washer. The LED array is from a Failed China Lamp and The Enclosure is a 10 CD Box. The Top Byzantine Structure is a Pepper Cap from Africa and a Furniture Knob.

Perpetual Candle – White LED Lamp on Ni-Cd

Perpetual Candle – Emergency Light 1W using LEDs, Solar panel can be also integrated with a single diode at input of LM317T. If your Solar Panel Voltage is low then use a DC/DC Converter or Joule Thief.

From Hobby Hound – DIY Electronics

Read Earlier Post – Perpandle Design

How It Works ?

I will give a short summary, The LM317 here configured for around 6.4V DC. The Q3 BC547 limits the current, you can select R3 to suit, make it 1/2W. The Ni-Cd battery pack 1.2 * 4 will not get Over-Current or Over-Voltage due to this circuit.

The IRF540 Mosfet or any other equivalent you have around, along with Q2 BC547 forms a current source for the parallel 12 LED array. Ultra-bright White LED at 20mA each or use a 1W ready LED Chip. R4/R6 can be selected for the Max LED current. The voltage of LED is around 3.1 and 20mA * 12 = 240mA is the max current. You can Tweak the design for even 5A or more but then you will need a DC/DC High frequency converter in place of LM317. The Current source also needs to switch to improve efficiency. A PWM on the mosfet gives brightness control. The entire solution (switching) can be found in many chips with semiconductor vendors today.

Also use Heatsinks for both devices, may not be required, test is out.

Two Floppy Boxes and Little Quickfix

Here two 1.44 Mb floppy boxes were used up creatively, an unique Desktop Utility was created. 1.44 Mb seems to be supersede-ed by Pen Drives or Thumb Drives. This is as Green as you can get, no plastic waste. Something rare, one of a kind. You don’t get these kind of things in the stores. [...]
